Q-SYS NS Series Gen 2 网络交换机快速入门指南说明书
QUICK START GUIDE®The Q-SYS NS Series Gen 2 switches offer a plug-n-play solution for Q-SYSsystem installers intending to deploy a local, isolated AV network for mediadistribution. The NS Series Gen 2 switches ship pre-loaded with a QSCdeveloped configuration tailored towards the real-time demands of Q-LAN™Audio and Video as well as Dante and AES67 streams. The Q-SYS NSSeries Gen 2 switches eliminate the need for time consuming networkconfiguration and troubleshooting on site, thereby reducing labor costs,minimizing system commissioning time and reducing the need for networksupport specialists.The Q-SYS NS Series Gen 2 switches include QSC developed AV&C (Audio, Video and Control) profiles that provide optimal QoS (Quality of Service) configuration for Q-LAN™ audio, Q-LAN™ video, Dante™ audio (standard and low latency modes), and AES67 audio streaming formats. The preloaded configurations for the NS Series Gen 2 switches provide DSCP (Differentiated Services Code Point) values appropriate for each AV&C profile in addition to advanced protocol detection and queue mapping to ensure that all time-critical media data described above is prioritized appropriately for on-time delivery.In order to ensure optimal performance for real-time media in situations with large amounts of multicast traffic, the Q-SYS NS Series Gen 2 switches have preconfigured IGMP Querier and IGMP Snooping functions to facilitate multicast filtering and forwarding whenever necessary.The Q-SYS NS Series Gen 2 products are economical, enterprise grade, access class, managed network switch products.The Q-SYS NS Series Gen 2 switches are NETGEAR AV Line M4250 series OEM hardware products that are preconfigured forQ-SYS AV&C applications. The Q-SYS NS Series Gen 2 switch products are offered in 10-port and 26-port models. All Q-SYS NS Series Gen 2 models offer 1 GbE (1000 Mbps) operation on their primary copper ports. That is, for 10 or 26 of their ports, respectively. Additionally, all Q-SYS NS Series Gen 2 switches offer 1GbE and/or 10GbE uplinks via optional SFP (SmallForm-factor Pluggable) modules. All Q-SYS NS Series Gen 2 switches are PSEs (Power Sourcing Equipment) and are compliant with IEEE 802.3af and IEEE 802.3at PoE and PoE+ (Power over Ethernet) standards, respectively. Additionally, PoE++ models can deliver up to 90 Watts of IEEE 802.3bt Power over Ethernet. 10-port models feature 8 powered ports while 26-port models feature 24 powered ports.Every attempt has been made to ensure that the preinstalled switch configuration natively provides all prioritization and management functions required for a typical Q-SYS installation, including common 3rd party devices, meaning these switches are targeted as true plug-n-play applications. However, should the Q-SYS system installer need to adapt the switch configuration for any reason, the QSC-supplied configurations provide default IP addresses and administrative credentials that allow a network professional to access the Q-SYS NS Series Gen 2 switch products using a common web browser.Recommended NS Series Gen 2 Network DeploymentsThe Q-SYS NS Series Gen 2 network switches provide a unique feature called IGMP Plus. This feature greatly simplifies system architectures by enabling the same well-known IGMP techniques across the entire AV over IP (AVoIP) network. This enhanced implementation for automatic multicast across a Layer 2 multicast network should require no user configuration when deployed in the recommended manners shown below using supported Q-SYS AVoIP protocols and technologies.Example A: Completely Isolated SystemsIn this scenario, individual Q-SYS systems within a facility are completely isolated islands with their own dedicated networks and no interaction with, or connection to, other systems or the facility’s infrastructure and services.This scenario will work completely turnkey with no adjustments to the switches required.Room 1Room 2Room 3Example B: Completely Isolated Systems with Switch ManagementIn many facilities with existing infrastructure and/or IT staff on hand, they may desire a connection to the AV switches for basic monitoring or management. The Q-SYS NS Series Gen 2 switches feature an OOB (Out of Band) port that can be used for direct access to the switch’s management functions without the need to connect to the AV network(s). This OOB port is configured for DHCP and will fall back to 192.168.0.239 if no DHCP service is available. Note: It may take up to 5 minutes for the OOB port to fall back to its default IP after initial power on or a reboot.Example C: Centralized System Management, Access to Corporate Services and/or InternetThe following is the most common deployment scenario for Q-SYS Systems. In this scenario, the systems are still largely isolated with respect to real-time, multicast, and high-bandwidth AV traffic, but the Core’s LAN B or AUX connections are used to provide centralized management, integration with corporate services such as VoIP, or provide the Cores access to the Internet for remote management and monitoring through Q-SYS Reflect Enterprise Manager. Refer to the Q-SYS Designer Help file for information on configuring the specific services present on a Core’s LAN B or AUX connection.Example D: Integrating Q-SYS SystemsIn some cases, it may be desirable to share content between systems or integrate a facility’s centralized paging and background music distribution. As long as only Q-SYS NS Series Gen 2 switches are interconnected, attention is paid to the bandwidth utilization of ISLs (Inter-Switch Link), and care is taken to avoid IP address conflicts as documented further on, the unique QSC configurations and IGMP Plus features of the Q-SYS NS Series Gen 2 will allow a scenario as shown below.Facility AudioFor applications beyond these scenarios, please consult a qualified AV&C network designer or engineer.DHCP ServerThe Q-SYS NS Series Gen 2 switches have a built-in DHCP server which has also been pre-configured by QSC, but is disabled by default.In Examples A - C above, it may be desirable to enable the DHCP server when not using static addressing within the individualQ-SYS systems. This can make configuring, managing, and servicing the system much easier as any computer plugged into the system’s switch should automatically receive an IP configuration within the scope of the system, thus be able discover and connect to it.When the DHCP server in the Q-SYS NS Series Gen 2 switch is enabled, it will assign devices attached to the switch an IP in the range of 192.168.0.151 - 192.168.0.254.Enabling the DHCP ServerWARNING! If you choose to enable the DHCP Server on an NS Series Gen 2 switch, DO NOT connect it to any other existing network infrastructure or to any other NS Series Gen 2 that also has its DHCP Server enabled!1. Connect your PC to either one of the Gigabit copper ports or the OOB (Out of Band) port.a. If using a Gigabit copper port, configure your PC’s Ethernet interface with a static IP address in the 192.168.0.xscope.b. If using the OOB port, it will default to 192.168.0.239 (when no DHCP server is present) which will also requireconfiguring your PC’s Ethernet interface with a static IP address in the 192.168.0.x scope.Note: It may take up to 5 minutes for the OOB port to fall back to its default IP after initial power on or a reboot.2. Open a web browser and type in the IP address of the switch.3. Select “Main UI Login”.4. Use the default login credentials (if still applicable).5. You will now see the System->Management->System Information screen.6. Select System->Services from the top banner menu.7. Select DHCP Server->DHCP Server Configuration from the left hand menu tree.8. Check the “Enable” radio button under DHCP Server Configuration: Admin Mode.9. Click the “Apply” button in the upper right.10. Click the “SAVE” icon in the upper right.If you wish to use the NS Series Gen 2 switches for DHCP addressing in a scenario similar to Example D, only enable the DHCP Server on a single NS Series Gen 2 switch, preferably the most central switch (the NS26-300+).Default IP Configurations:192.168.0.110, 255.255.255.0 : NS26-300+ (26-port PoE+)192.168.0.111, 255.255.255.0 : NS26-1440++ (26-port PoE++)192.168.0.120, 255.255.255.0 : NS10-125+ (10-port PoE+)192.168.0.121, 255.255.255.0 : NS10-720++ (10-port PoE++)Default Credentials:Username: adminPassword: qscsystemsIMPORTANTDO NOT load any firmware or configuration versions other than those approved by QSC. The firmware version qualified by QSC will not always be the most recent release found on the Netgear website for the M4250 product line.It should be noted that QSC Support can only assist with support inquiries when the NS Series Network Switch is running the original, unedited switch configuration. QSC does not support applications beyond the supplied configurations, such as additional VLANs, other AV&C protocols etc. If necessary, a factory reset operation will return the Q-SYS NS Series to the QSC-provided default configuration.Changing Default IP Configurations or Accommodating Multiple Same-model Switches It may be necessary to change the default IP configuration on one or more Q-SYS NS Series switches to avoid conflicts orto fit your specific topology and network addressing schema. Use the following steps to verify and/or change a switch’s IP configuration:1. Isolate the switch. (Disconnect it from any existing network or other switches.)a. Connect your PC to either one of the Gigabit copper (numbered) ports or the OOB (Out of Band) port.b. If using a Gigabit copper port, configure your PC’s Ethernet interface with a static IP address in the 192.168.0.xscope.2. If using the OOB port, it will default to 192.168.0.239 (when no DHCP server is present) which will also requireconfiguring your PC’s Ethernet interface with a static IP address in the 192.168.0.x scope. Note: It may take up to 5minutes for the OOB port to fall back to its default IP after initial power on or a reboot.3. Open a web browser and type in the IP address of the switch.4. Select “Main UI Login”.5. Use the default login credentials (if still applicable).6. You will now see the System->Management->System Information screen.7. Select Management Interfaces->IPv4 Management VLAN Configuration from the left hand menu tree.8. Adjust the IP Address, Subnet Mask, and Gateway fields as necessary.9. Click the “Apply” button in the upper right. If you’ve changed the IP Address, you will now lose connection to the switchand it will log you off as it changes its IP configuration, however your web browser may not show that anything hashappened.10. Type the new IP address of the switch into your web browser.11. Select “Main UI Login”.12. Use the default login credentials (if still applicable).13. Click the “SAVE” icon in the upper right.Changing Default CredentialsIt may be desirable to change the login credentials for increased security. To change password for the administrator account:1. Connect your PC to either one of the Gigabit copper (numbered) ports or the OOB (Out of Band) port.a. If using a Gigabit copper port, configure your PC’s Ethernet interface with a static IP address in the 192.168.0.xscope.b. If using the OOB port, it will default to 192.168.0.239 (when no DHCP server is present) which will also requireconfiguring your PC’s Ethernet interface with a static IP address in the 192.168.0.x scope. Note: It may take up to 5minutes for the OOB port to fall back to its default IP after initial power on or a reboot.2. Open a web browser and type in the IP address of the switch.3. Select “Main UI Login”.4. Use the default login credentials (if still applicable).5. You will now see the System->Management->System Information screen.6. Select Security->Management Security from the top banner menu.7. Select Local User->User Management from the left hand menu tree.8. Check the “admin” account, change the “Edit Password” drop down from “Disabled” to “Enabled” and enter your newpassword into the “Password” and “Confirm Password” fields.9. Click the “Apply” button in the upper right.10. Click the “SAVE” icon in the upper right.WARNING! If you lose or forget the administrator account credentials, the only course of recovery is a factory reset procedure as documented below!Factory ResetTo restore the Q-SYS NS Series switches to their factory defaults, press and hold the reset switch on the rear for 5 to 10 seconds, then release.

平衡与非平衡输入
音频输入方面,具有平衡式输入和非平衡式输入 两种方式.
我们普通的莲花头也就是两芯RCA接头属于非 平衡输入方式,只放大+信号,-信号与屏蔽端共用；
而平衡式XLR输入采用的是三芯插头1地2正3 负；+、-信号都是独立放大器,屏蔽端接地；
平衡输出的目的就是为了减少干扰,除非设备不 是平衡输出的就应该使用不平衡输出的接线.所以 接线之前应该注意设备输入、出接口的标识 BALANCE平衡UNBALANCE不平衡

定压信号和定阻信号的区别
定压信号输出,是由电压来推动扬声器,特点是输 出的电压大、电流小.因此,定压信号传输距离远,扬 声器可以多个并联,但音质比定阻信号稍差. 定阻信号输出,是以电流来推动扬声器,特点是输出的 电流大,电压小.定阻信号传输距离不超过100米,音质、 音效好.
音频的基础知识
额定功率是一种平均功率,而实际上扬声器工作 在变功率状态,它随输入音频信号强弱而变化,在弱音 乐及声音信号中,峰值脉冲信号会超过额定功率很多 倍,由于持续时间较短而不会损坏扬声器,但有可能出 现失真.因此,为保证在峰值脉冲出现时仍能获得很好 的音质,扬声器需留足够的功率余量.一般扬声器能承 受的峰值功率是额定功率的2-3倍

The assortment of connections on the Core 110f.Connecting the POTS LineIn this design, the Core 110f connects to a Plain Old Telephone Service (POTS) analog line for teleconferencing. The modular jack on the core’s rear panel connects directly to the phone line via a suitable cable. A User Control Interface (UCI) created for a TSC-7 touchscreen controller contains the phone dialer, volume, and other controls, making them readily accessible on the tabletop. The TSC-7 connects to the core through the local area network (LAN), which is described below.For more information about connecting the Core 110f to a POTS line, see the QSC Technical Note Interfacing POTS with a Conference Room via Core 110f.Connecting the NetworkTwo RJ45 Gigabit Ethernet jacks provide connectivity to the primary LAN, and if required, to a redundant or auxiliary one. The primary network is labeled LAN A and the redundant one is LAN B. LAN B can also be configured as an auxiliary LAN for use on a control or corporate network.The LAN conducts all communication between the core and other network devices, such as any TSC touchscreen controllers. Connecting the USB Type B PortIn this design the Core 110f is configured with one USB endpoint serving as a speakerphone. This feature allows you to operate a teleconferencing session using software such as Skype, GoToMeeting, Lync, Google Hangouts, etc., on the PC connected via the USB port.For more information about using the Core 110f with a PC via USB, see the QSC Technical Note USB Endpoint functions in Core 110f: Soundcard or Speakerphone.QSC Systems / Q-SYS Core 110f POTS Design Application Guide 56 QSC, LLC / Q-SYS Core 110f POTS Design Application GuideFeatures in Q-SYS DesignerChannel GroupA Channel Group (Figure 7) is an efficient and convenient way to drawand apply one or more processing steps simultaneously to two ormore parallel channels of audio.Double click on the Channel Group to open it; we see that in thisdesign it applies high-pass filtering and parametric EQ to each channel(Figure 8).You may configure these eight channels separately, or you mayconfigure some or all them simultaneously; use the selection buttons(1 through 8, plus Prev, Next, Exclusive, Select All, and Select None) tochoose which ones to configure.The high-pass filter and parametric EQ blocks can be opened to allow configuration. The settings you configure will apply to theselected channels.Figure 7.Figure 8.Figure 9. High-pass filter configuration above, and parametric EQ at right.Gating Automatic Mic MixerAs the name suggests, The Gating Automatic Mic Mixer is a multi-channel mixer that has adjustable noise gating on each channel. The one in the default design is configured for eight input channels and one output. It is especially suitable for teleconferencing use because it can take out possibly distracting background noise and improve intelligibility.Figure 10 shows the component opened up for configuration. Like a conventional mixer, it combines multiple audio signals together, but it additionally adds noise gating with a maximum number of open mics, along with adjustable attenuation and threshold parameters. The “Last Mic On” feature leaves the last active mic ungated even when no one is speaking, allowing some background noise to come through and prevent the illusion on the far end that the connection has been lost.Figure 10.

Q-Sys系统完全集成解决方案介绍说明书
Q-Sys™ is a complete integrated system that encompasses everything from the audio input to the output of the loudspeakers; it provides all the routing, processing, control and monitoring, while maintaining the audio quality and reliability QSC has come to be known for. Physically located near audio sources and destinations, I/O Frames provide the points of connection used to interface Q-Sys with other components of the audio system, such as mixers and power amplifiers. Each I/O Frame features four card slots, which can support up to four of the following I/O cards, mixed and matched in any configuration: Mic/Line Input card — Four channels of switchable mic/line-level analog audio input with 48V phantom power (available with standard or premium pre-amps and A/D converters). Line Output card — Four channels of balanced, line-level analog output. DataPort Output card — Four audio output channels (2 DataPorts) for connection to DataPort equipped QSC amplifiers. AES Input/Output card — Four input and four output channels of AES-3 digital audio. The I/O Frame will also support a single network card (such as Cobranet, and future cards such as Dante / AVB) to provide a bridge to the Q-Sys Core, up to 16 inputs and 16 outputs.One of the primary development goals was to create a platform that had nearly unlimited resources; Q-Sys truly lives up to that goal with unrivaled processing breadth and depth. The design interface was created specifically to harness its unmatched power while remaining intuitive and easy to use. The processing tools are extensive and simple to apply. Once the system is designed, you will find that Q-Sys also offers a useful suite of trouble shooting and measurement tools. The strength of the centralized architecture used by Q-Sys is that it facilitates the implementation of total or partial system redundancy. A system can be created with Core, Network, I/O Frame and even amplifier redundancy. In a redundant Q-Sys system, a problem with any of the primary devices will result in the back-up device taking over. If, for example the Core experiences a failure, the backup core automatically takes over ensuring continued flawless operation.Q-Sys is a powerful and reliableunified system that features rock-solidperformance backed by the unrivaledservice and support QSC has built itsreputation on.

1.系统设计特点及概述鉴于该系统设计包括多个专业扩声系统，为了达到系统整合的目的，同时又要保证系统稳定性和先进性，这里我们选用QSC公司最新推出的大型网络音频矩阵Q-sys系统为整套系统的核心。
由于Q-Sys系统具有极大的音频处理能力以及通道处理能力，实现Q-Sys 网络音频处理系统最大利用率，达到资源配置最优化。
1. Q-Sys系统介绍Q-Sys系统是美国QSC公司最新研制推出的一套大型网络音频矩阵处理系统。
该系统重新诠释了网络音频系统，具有：非凡的音频处理能力、超强的系统整合能力、磐石般的系统稳定性、简单易懂的可操作性。
Q-Sys系统主要由音频处理主机CORE、音频接口箱I/O FRAME、控制软件以及千兆网络组成。
所有的设备通过千兆网络连接起来即可完成工作。
如图1CORE主机CORE主机是Q-Sys系统的处理核心，音频系统中所有的音频信号处理、路由和控制信号全部是在这里进行的。
CORE主机分有三个型号：CORE1000、CORE3000、CORE4000。
三种主机分别可以处理64X 64、128X 128、512* X 512个音频通道，是当今世界上处理能力最强的音频处理主机。
CORE主机摒弃了传统音频处理主机采用DSP芯片进行音频信号处理的老方式，而采用全新的音频处理核心-多核64位中央处理单元进行音频信号处理。
采用这种全新的处理引擎后，CORE主机的信号处理能力远远大于传统采用DSP芯片作为处理核心的音频处理主机。
对比此前处理能力最强图2. CORE主机的PEAVEY的NION N6型音频处理主机，最小型的音频处理主机-CORE1000的音频处理能力是NION N6的五倍。
CORE主机内部内置了多种音频处理模块，如：分频器、混音器、自动混音台、噪声门、路由器、动态处理器、噪声发生器、参量/图示均衡器、动态显示器、音频文件播放器、RTA测试工具等等，能够满足各类场所音频系统的需要。
超强的处理能力、丰富的音频处理模块，使CORE具有充足的资源来进行音频信号处理，给音响系统设计师提供了一个自由的平台，供其任意设计自己想要设计的音响系统。
I/O FRAME 音频接口箱I/O FRAME是1U模块化音频接口箱，最大支持16个音频通道，采用32比特浮点信号处理方式和高端数模、模数转换器，使整套系统具有高保真音质效果。
机身集成四个卡槽，可以配置不同种类的输入输出接口卡。
目前支持的卡的类型为：CIML4 :图3.|/OFRAME音频接口箱麦克风/线路输入标准卡；CIML4-HP :麦克风/线路输入高性能卡；COL4 :标准线路输出卡；CODP4: QSC开关电源功放专用卡；CAES4: AES信号输入输出卡。
I/O FRAME可以和CORE安装在一起，也可以安装在音频网络可以覆盖的任何地方。
这种系统结构极大的增加了系统设计的灵活性，并且大大的削减了铺设模拟音频线缆的长度以及铺设成本。
由于所有的处理和控制都是在CORE中进行的，因此单个I/O FRAME的故障只能影响到这个接口箱的输入输出，而不会影响整个处理控制中心。
I/O FRAME机身集成了8个GPIO通道（继电器控制端、电压控制端和地线），GPIO可以通过软件配置为受干触点控制或者电位大小控制，也可以输出TTL 电平等控制信号，控制外部设备。
网络QSys 系统基于千兆以太网实时传输无损音频信号，一个千兆网线可以传输512 个音频通道，且最大支持网络十跳。
Q-Sys 系列内产品全部采用高质量的信号转换器，网络延时仅为0.667 毫秒，而QSys系统的任一输入到任一输出的最大总延时也仅仅为固定的2.5毫秒。
值得注意的是，这里的延时指的是系统固定延时，无论经过网络节点多少、无论内部增加多少DSP处理环境，系统整体延时为固定的2.5毫秒，为音响设计师在系统延时控制上提供便利。
Q-Sys 系列内产品CORE 和I/OFRAME 配备的为标准网络传输设备，内部的音频信号和控制信号在一个网络中进行传输，无需将控制和音频信号分成两个网络单独传输。
Q-Sys 系列内产品CORE 和I/OFRAME 均具有双网口，即支持双网络。
当一个音频网络瘫痪的时候，备用网络可以无延时的接替工作。
软件Q-Sys系统有一套非常直观、易懂、易操作的设计软件—“Q-Sys Designe” 音响系统设计师学习起来十分迅速。
Q-Sys Desig ner软件无论是在“在线”或者“离线”的状态下，都可以运行工作。
在离线状态下，音响设计人员可以学习使用软件，并在电脑上模拟系统运行，无需任何硬件设备。
方便大家进行系统设计和仿真模拟。
值得一提的是，Q-Sys Desig ner的仿真速度非常得快，可以大大节省我们在设计大系统时候的时间。
此外软件中集成了强大的帮助系统，在操作者需要的时候提供必要的协助。
系统设计简单得就像图示化的音频处理组件堆叠一样，会使得系统设计者更加专注于系统解决方案的设计而不是怎样去运行软件。
软件中还有很多十分使用的处理模块和工具，当一个设计师使用QSys系统的时候，当一些细节和小技巧被掌握后，系统的设计会更加有效。
除了设计软件之外，系统还可以制作图形化的控制界面。
控制界面的编辑就是将处理组件中的指示器和控制器拖拽到控制面板编辑器中，此外还能够在界面中添加图片、线以及其他一些图形等元素。
编辑器可以自动生成控制页面或者定制的控制页面。
系统操作人员就可以通过密码，使用友好的人机交互界面来控制整个音响系统了。
图4.软件界面系统的可靠性但凡大型的系统，一般对系统可靠性都具有很强的需求。
传统的模拟系统通常采用系统冷备份方式，当系统出现故障的时候，需要重新连接系统，容易出现系统连接错误、导致系统不能马上工作。
而Q-Sys系统具有热备份机制，可以实现实时的系统备份功能供用户选择。
如图5所示。
Nct'ivork A卩run ary Corphktwo卩k B B<jckup Cofe Procesior图5.主机、网络、接口箱自动热备份a）主机热备份Core支持双机热备份，两个主机互为备份，每300毫秒进行系统控制参数同步，当主机出现故障的时候，备份机可以马上接替主机工作，不会造成系统停止。
无需任何变成、无需任何软硬件增加，即可完成主机热备份b）音频接口箱热备份I/O Frame支持双机热备份，两个接口箱互为热备份。
当主接口箱出现问题的时候，备份接口箱可以自动接替主接口箱工作。
两个接口箱可以同时接在一套功率放大器上面，由于其内部设计了备机断开机制，因此不会出现输入阻抗减小一半的情况。
无需任何变成、无需任何软硬件增加，即可完成接口箱热备份。
c）网络热备份Q-Sys系统的所有设备均支持双网络，具有两个网口，实现网络系统的双备份。
当一个网络出现问题的时候，可以自动切换到另一个网络上面。
（无延时）d）功放热备份QSC功率放大器在配合Q-Sys系统工作的时候，可以实现N+1备份。
即用一台功率放大器就可以实现对N（ N小于等于8）台功率放大器的备份工作。
实现功放备份的功能的时候，需要增加一台功放倒备器一DAB-801。
每台DAB-801可以实现一台两通道功率放大器备份4台两通道功率放大器，两台DAB-801可以级联，实现1台两通道功率放大器备份8台两通道功率放大器。
该功能多用于广播系统，在一些重要的会议场所也可以进行功率放大器的备份。
Q-Sys系统提供了这么全的备份功能，用户可以根据自身系统的需要，选择需要的备份设备。
对功率放大器和扬声器的整合Q-Sys系统不仅仅是一套网络音频处理系统，它还整合了QSC后端扩声设备-功率放大器和扬声器。
QSC所有开关电源功率放大器都可以通过Q-Sys系统进行远程遥控和监控（该监控功能还包含对功放后扬声器回路的监控），而所有QSC无源系列扬声器也全部集成到系统中，内置所有型号扬声器的“本征校正”音频处理模块，使得系统扬声器音质调整非常简单。
内置LUA编译器Q-Sys系统内置很多逻辑功能模块，帮助音响系统设计工程师设计功能更加强大的音响系统。
除此之外，系统还内置了LUA编译器，通过LUA语言变成, 设计逻辑功能更加复杂的音响系统。
2.本项目系统配置本系统包含会议扩声系统，采用一套Q-Sys 系统即可完成全部系统功能。
既实现了系统集中化管理和控制，又实现了资源优化配置目的。
配置原则：Q-Sys 系统在主机房配置系统主机CORE,然后通过网络连接每层所有的Q-Sys系统设备。
控制电脑也设立在主机房。
会议扩声场所分布在每个楼层，且有的楼层具有较多的会议室，基本配置原则是在每个会议室内配置一台I/O FRAME 音频接口箱，并根据房间内的音源输入数量（话筒、DVD 等）和扬声器输出回路确定需要的音频输入卡和输出卡的数量。
网络Q-Sys系统的千兆网系统可以单独建立一套千兆网系统，也可以利用大楼内部现有的千兆网络系统（资源优化配置）。
如果跟大楼内部网络系统共用网络的时候，需要给Q-Sys系统划定足够带宽的VLAN。
如果为了增加系统的可靠性，可以采用两套网络运行，Q-Sys系统支持双网络运行，且可以无缝切换主网络和备份网络。
Q-Sys系统的网络需求：a）必须为千兆以太网（使用千兆网交换机和千兆网线或者光纤均可）b）网络最大不可超过10 跳c）网络交换机支持QoSd）网络交换机端口至少支持4 个优先级功率放大器和扬声器配置原则会议扩声系统采用定阻方式驱动扬声器。
根据会议室空间大小，选择合适的AD 系列会议专用扬声器，并根据扬声器功率，选择合适的CX 系列定阻功率放大器即可。
3.系统特点介绍a）利用网络传输音频信号。
传输距离远、信号损失小。
采用模拟系统，既会造成线缆成本的大大增加、施工难度的增加、人力成本的增加；还会造成模拟音频信号在传输过程中信噪比下降和信号衰减，进而造成整个广播系统音质的下降，直观的感受就是语言清晰度不够、背景音乐音质不够优美等。
而Q-Sys 系统采用千兆以太网传输音频信号，可以有效的避免音频信号传输过程中的种种问题和施工上的难点。
利用一根千兆网线可以传输512 个音频通道，大大降低了施工成本和线缆成本；并且声音信号无压缩、无衰减损失。
b) 设备集中化管理。
管理智能化、人性化。
传统的系统通常不能够对系统所有设备进行管控、操作也不人性化，使用和维护起来十分不便。
如果是一个小的系统还无所谓，但是用在一个大型系统中那么使用起来就是非常繁琐了。
工作人员要面对大量的广播设备，需要经过专业的培训才能够了解系统的操作。
如果设备一旦出现问题，就要往返于设备间之间进行，增加系统的使用难度。
Q-Sys系统具有图形化、中文的，友好的人机交互界面，系统操作人员无需进行专业的培训即可根据才做界面上的中文提示进行系统操作。
并且系统具有权限管理机制，不同级别的系统管理人员具有不同的权限，需要根据授权或者密码对系统进行操作，防止系统误操作的发生。
