HXM-1 Hx Series微型电麦前馈器用户指南说明书

HXM-1 Hx Series Microphone Preamplifier User’s Guide The Hx Series from Demeter Amplification is a revolutionary approach in tube design utilizing innova -tive tube circuitry for the amplification functions and the latest in solid state for the driver functions. All Hx Series equipment use the finest quality components featuring metal film resistors, high quality film capacitors, and custom toroidal power transformers housed an attractive aluminum and steel single space rack mount case. All units feature fully regulated power supplies supplying 200V to the tubes and + and - 18V for the solid state components, giving all Hx series components tremendous head room up to +28 dB output into 600 ohms.The HXM-1 is a two channel microphone preamplifier utilizing Jensen transformers and the revolution -ary Hx Series tube amplification circuitry. Each channel has variable gain (30 to 60 dB) instrument input, low cut, phase, pad, overload indicator, volume, 48V phantom and 10 section VU with selectable sensi -tivity.INPUTS, CONTROLS AND FEATURESCH Input: instrument level input used to amplify guitars, keyboards etc. to line level. This input turns the microphone preamplifier into a tube direct box.Low Cut: this switch inserts a 6 dB per octave low cut filter starting around 200 Hz and is down -12 dB at 40 Hz. The slow slope reduces phase shift.Microphone Pad: this switch inserts a 20 dB pad in front of the Jensen microphone transformer; it is used to prevent overload distortion (red LED above) when the gain control cannot. it also prevents the transformer from saturating. Overload is indicated by the red LED above the switch.Phantom: this switch turns on the 48V phantom power to microphones requiring it. This switch should not be turned on for dynamic microphones or other microphones that do not require it. It should not be turned on for any microphones plugged into the 1/4” TRS inputs in the back of the unit or damage to microphone may result. Phantom on is indicated by the yellow led above.Phase: this switch reverses the phase of the microphone input. It can be used to match phase of differ -ing inputs or as an effect to enhance a mixing of sources by canceling out some bass frequencies.Gain: this control changes the gain (30 to 60 dB) of the tube preamplifier by controlling the amount of feedback going to the tube. The gain should be set at the lowest setting that will still produce a usable signal level. It should not be set too high or the unit will overload (red LED) and distort. If turning down the gain does not stop overloading, use the microphone pad switch. It is OK for the overload LED to flicker occasionally.6990 Kingsbury Road | Templeton, CA 93465 | 805-461-4100 | /HXM-1 Hx Series Microphone Preamplifier User’s Guide Volume: this control is a fader between the tube microphone preamplifier and the balanced line driver. It’s setting does not effect overload. It should be set near its maximum setting and used only for fine tuning signal level or for fades in or out.Meter: this switch controls the sensitivity of the VU LEDs and is calibrated for +4 dB out and -10 dB in.Overload: this LED indicates if the signal level of the tube amplifier is near reaching its distortion level. it is set to start flickering 6 dB before distortion is reached. A little flickering is fine. The gain must be lowered or Microphone Pad engaged if the LED is constantly on.Phantom LED: this yellow LED indicates that phantom power is being provided to the microphone input.VU: This row of LEDs indicate the output level going to the balanced line output jacks in standard vol -ume units. The level is indicated above each LED. There is no distortion if you go past 3 VU. The micro -phone preamplifier has over 18 dB more headroom above the meter’s highest indication.REAR PANELVoltage Selector: selects mains voltage 115 volts U.S.A. and 230 volts for Europe. WARNING: damage to this equipment will occur if this switch is improperly set.Fuse:******************************************.Output: balanced three pin XLR connector and balanced TRS 1/4” phono jacks. WARNING: do not hook up output connectors to any inputs that have 48 volt phantom appearing on them. This will damage the units output circuitry.Input: balanced Jensen transformer inputs on both three pin XLR and TRS 1/4” phono jacks. WARNING: turn off 48 volt phantom when using TRS 1/4” jacks. Damage will occur to the microphone when using unbalanced microphone input cables.HOOKUP TIPS1. Make sure that the tube microphone preamplifier is connected to inputs that are designed to operate at line level, otherwise distortion could result.2. Avoid ground loops. If hum occurs it may be necessary to telescope some grounds. This is done by cutting the ground wire on only one side of the three pin XLR connector.3. Keep wiring short and neat.4. Make sure AC grounds are properly connected.5. Don’t hesitate to call the factory or your Demeter dealer with any questions. We are here to help.6990 Kingsbury Road | Templeton, CA 93465 | 805-461-4100 | /。

8002功放音频IC芯片替代型号HX8358功放

8002功放音频IC芯片替代型号HX8358功放一、前言:8002系列率功放芯片，是前几年生产和开发蓝牙、MP3的音箱用的最广泛的一个芯片，也可以说是最经典的一款模拟芯片。

在淘宝搜素一下，各种各样的8002都有。

但随着时间的推移，产品的升级，很多的新的产品它适用不了，比如工作电压超过５V,功率要求比较大一点的，它都不能做。

因此就会有新的产品来替代它。

下面就针对我公司的功放芯片，给大家介绍一下。

先例出几款常用功放芯片的比较：从列表可以看出，我公司推出的HX系列功放芯片，工作电压和输出功率明显的高于其它的功放。

二、为什么要向大家介绍我公司HX8358这个功放芯片？做电子音频产品的，大家都知道市面上有一款8002系列的功放音频IC。

据我所知，8002一共有6个版本，8002A、8002B、8002C、8002D、8002E、CSC8002,搞的大家在使用上极其的不方便，有时还会卖错8002.它们的不同之处，就是功率的大小不一样,价钱也是不一样的。

但8002不管是那个版本，它的最高工作电压只有5.0Ｖ,超过5.0Ｖ,在生产或者用户在使用中，肯定会烧坏的，这是已经求证过的事实。

这方面，浙江省的生产公司就身有体会，他们在做童车、摇摇车的过程中，因使用的是4节干电池供电。

4节干电池的电压远远超过8002极限工作电压5.0V。

因此在生产的过程中，动不动就烧坏8002，发出去的成品，也是成了严重的售后问题。

有的生产公司为此把烧坏的芯片拿去开光，结果看到芯片的内部已经是烧黑了。

ＨＸ8358，他的工作电压最高可达7.0V,工作电压范围：2.5V—7V,根本不用担心4节干电池烧坏芯片的问题。

音质和功率也不会比8002差，功率甚至比8002大，可以做到5Ｗ的功率三、HX8358芯片功能说明：QQ:298391364HX8358是一款超低EMI，无需滤波器，AB/D类可选式音频功率放大器。

6V工作电压时，最大驱动功率为8W（VDD=6V,2ΩBTL负载，THD<10%），音频范围内总谐波失真噪声小于1％，（20Hz～20KHz)；HX8358的应用电路简单，只需极少数外围器件；HX8358输出不需要外接耦合电容或上举电容和缓冲网络四、典型应用电路：五、芯片功能主要特性：１、超低EMI，高效率，音质优２、AB/D类切换、单通道３、VDD=6V，RL=2Ω，Po=8W，THD+N≤10%４、VDD=6V，RL=4Ω，Po=5W，THD+N≤10%５、(防失真关断模式)６、宽工作电压范围2.5V—7V７、优异的上掉电POP声抑制六、8W输出功率设置：有拿到样品的朋友问我这样的问题，HX8358的输出功率达不到8W，声音大小和8871的差不多。

With the right care and attention it will give you many years of trouble free operation.Before operating the system, please read this manual fully to obtain the best results from your new product, and retain it carefully for future reference.2.1 Contents• AQ-SWA8-1BT Active Subwoofer• User/Installation Manual• Bluetooth Antenna2.2 FeaturesThe AQ-SWA8-1BT active subwoofer is a high quality, robust and durable subwoofer with built-in amplifier and outputs for connection of standard full range speakers. Tuned Port for enhanced bass response. Designed and built to withstand the harsh IPX4 conditions associated with use in marine, boat, pool or spa applications.Rated at 288W max power output (144 watts for the sub and 72 x 2 to the full range speakers) with a frequency response of 26Hz-125Hz for the sub frequencies and 125-20Hz for the full range frequencies. The amplifier is both 2 Ohm and 4 Ohm stable, so a maximum of four 2 Ohm speakers can be connected.The AQ-SWA8-1BT active subwoofer features an 8” DVC (Dual Voice Coil) speaker that will deliver powerful, warm bass to your existing speaker setup, adding musicality and depth to your favourite audio content.Variable stereo RCA inputs allow optimum performance from all devices. There are 3 selected ranges from 400mv, 2V and 4V inputs.As with all Aquatic AV products we only use high quality materials to construct our active sub-woofers to provide a durable, long lasting and great sounding addition to your waterproof stereo system.The cabinet has been treated to an IPX4 rating and the PCB is conformal coated.The AQ-SWA8-1BT requires a wiring harness in order to connect to power and speakers.All open wire connections should be soldered and protected against water and dust for best long term performance.1. You will need an Aquatic AV AQ-UNH-2 wiring harness or the factory harness on your stereo system to complete the install.2. Follow the Wiring Harness diagram below. Use a minimum of 18 gauge wire for power and ground.3. When the unit is powered on you will see the LED light up red on the panel.3.1 Connecting the Subwoofer 3.2 Wiring Harness Power Antenna (7)No lower than a 4 Ohm speaker should be used or damage may occur to the subwoofer.Make sure the polarity of speakers are connectedcorrectly.(White/strip)4 Ohm4 Ohm 4 Ohm4 OhmLeft Front SpeakerRight Front SpeakerRight Rear Speaker OPTIONALLeft Rear SpeakerRCA Input (Red & White)Red Power LEDVariable Voltage Input Selector Wiring Harness connections (see below)SMA Bluetooth Antenna CableOPTIONALIncluded with your Aquatic AV Bluetooth Subwoofer is an upgraded Bluetooth Antenna. When installed this Antenna will boost the range of your AQ-SWA8-1BT Bluetooth signal.Please read the precautions and installation instructions below before installing theBluetooth Antenna.3.3 Bluetooth Antenna 3.3.2 Bluetooth Antenna Installation1. Locate the 6” SMA Bluetooth Antennaconnection cable coming out of the main panel onthe AQ-SWA8-1BT.2. Make sure the arrow is pointing directly upwardstowards the sky when the antenna is mounted toensure the Bluetooth range is maximized.3. Screw on the provided Bluetooth Antenna,avoiding bending the cable at a 90° angle.4. Install the Bluetooth Antenna making sure thearrow is pointing directly upwards towards thesky. If there is no suitable surface to screw it in,we recommend using a good quality double sidedtape.Make sure the arrow is pointing directly upwards towards the sky when the antenna is mounted; this will ensure that the range is maximized.If there is excess antenna cable length make sure this is coiled and not bent as bending may cause damage to the cable.For spa or hot tub installation the antenna should be located above the waterline otherwise Bluetooth range will be drastically reduced.3.3.1 Bluetooth Antenna PrecautionsListening to Devices Active Subwoofer AQ-SWA8-1BT 4.1 Listening via Bluetooth4.1.1 Pair with Bluetooth Device1. Switch on your Bluetooth device.2. Select ‘AQUATIC AV’ from the list of available devices to pair (no password is needed).Only one Bluetooth device can be paired with the Bluetooth Subwoofer at any time.4.1.2 Play Bluetooth Device1. Bluetooth mode will be activated once a Bluetooth device is paired.2. Play the song from device and the sound will play through the subwoofer.3. Play/Pause, track forward/back and volume up/down can be controlled directly from yourBluetooth device.4.2 Listening via Auxiliary Input1. Connect your MP3 device to the RCA inputs.2. Turn the Variable Voltage Input Selector switch to determine the best sound quality foryour input device (400mV, 2V or 4V). Smartphones will typically use the 4V setting.The RCA input connections are designed for a full-range audio signal and when used in conjunction with a ‘sub’output (typically a single green RCA) from your stereo source unit will mean the AQ-SWA8-1BT can only be usedas a subwoofer (i.e. without the 2x full-range speaker outputs).If using a single RCA ‘sub’ output then an RCA Y adaptor must be used to provide input to both red and whiteRCA inputs on the subwoofer.Inputs...................................................Outputs.................................................Cone Size..............................................Power (max @ 2ohms)............................Frequency Response...............................Sensitivity..............................................S/N Ratio...............................................Waterproof / Dustproof............................Conformal PCB coating...........................Bluetooth, 2x RCA with variable 400mV, 2V or 4V input2x full range speaker output8”288W (144W subwoofer + 2x 72W speakers)26Hz - 125Hz (subwoofer), 125Hz - 20,000Hz (speaker outputs)86dB≥78dBYes IPX4Yes5.1 Specifications5.2 DimensionsSpecifications & Dimensions Active Subwoofer AQ-SWA8-1BTWarranty Information Active Subwoofer AQ-SWA8-1BTAquatic AV offers a limited warranty of our products on the following terms:Length of warranty2 years on audio systems, electronics, speakers, and accessories (receipt required).CoverageThis warranty covers only the original purchaser of a Aquatic AV product purchased from an authorized Aquatic AV dealer in the United States.

HX8321应用说明
输入电阻（Ri ）
HX8321内部设有两级的放大，第一级增益可通过外置电阻进行配置，而第二级增益是内部固定的。

通过选择输入电阻的参数值可以配置放大器的增益：
（1）
输出与反馈的平衡取决于电路的阻抗匹配情况，CMRR ，PSRR 和二次谐波失真的消除也可以得到优化。

因此采用精度为1％的电阻优化的效果更为显著。

在PCB 布局时，输入电阻应尽量的靠近芯片的输入引脚以获得更好的信噪比效果和更高的输入阻抗。

低增益和大电压信号可以使得芯片的性能更为突出。

退耦电容Cs
在放大器的应用中，电源的旁路设计很重要，特别是对应用方案的噪声性能及电源电压纹波抑制性能。

HX8321是一款高性能的音频功率放大器，需要适当的电源退耦以确保它的高效率和低谐波失真。

退耦电容采用低阻抗陶瓷电容，尽量靠近芯片电源供电引脚，因为电路中任何电阻，电容和电感都可能影响到功率转换的效率。

一个220uF 或更大的电容放置在功率电源的附近会得到更好的滤波效果。

典型的电容为220uF 的
电解电容并上1uF 的陶瓷电容。

输入电容Ci
HX8321用在单端输入系统中，输入端是个高通滤波器，输入电容是必须的。

输入端作为高通滤波器时，滤波器截止频率的计算公式如下：
12c f RiCi
p =
（2）
输入电阻和输入电容的参数直接影响到滤波器的下限频率，从而影响放大器的性能。

输入电容的计算公式如下：
1
2Ci Rifc
p =
（3）
如果信号的输入频率在音频范围内，输入电容的精度可以是±10％或者更高，因为电容不匹配会影响滤波器的性能。

过大的输入电容，增加成本、增加面积，这对于成本、面积紧张的应用来讲，非常不利。

显然，确定使用多大的电容来完成耦合很重要。

实际上，在很多应用中，扬声器（Speaker ）不能够再现低于100Hz －150Hz 的低频语音，因此采用大的电容并不能够改善系统的性能。

除了系统的成本和尺寸外，噪声性能被输入耦合电容大小影响，一个大的输入耦合电容需要更多的电荷以达到静态直流电压（通常为电源中点电压即1/2V DD ），这些电荷来自于反馈的输出，往往在器件使能时产生噪声。

因此，基于所需要的低频响应的基础上最小化输入电容，开启噪声能够被最小化。

旁路电容(CBYP)
在HX8321应用电路中，另一电容C B （接BYP 管脚）也是非常关键，C B 会影响PSRR 、开关/切换噪声性能。

一般选择0.1uF ～1uF 的陶瓷电容。

除了最小化输入输出电容尺寸，旁路电容的尺寸也应该详细考虑。

旁路电容C B 是最小化开启噪声最重要的元器件，它决定了开启的快慢及输出达到静态直流电压（通常为电源中点电压即1/2V DD ）的过程，过程越缓慢，开启噪声越小。

选择1.0uF 的C B 和一个小的Ci(在0.033uF ～0.1uF)将实现实质上没有噪声的关断功能。

在器件功能正常（没有振荡或者噼啪声）且C B 为0.1uF 时，器件会更多的受到开启噪声的影响。

因此，在所有的除了最高成本敏感的设计中推荐使用1.0uF 或者更大的C B 。

HX8321输出滤波器
在不加输出滤波器的情况下使用HX8321，放大器到扬声器的连线的长度一般在100mm 以下。

在手机等便携式通信设备应用中，都可以不用输出滤波器。

在一些环境等条件不允许和一些特殊的情况下，要加入输出低通滤波器，比如LC 滤波器。
