Limiter (Limit)
Sets the signal level threshold at which the module will begin to limit the level of its output signal. Clockwise rotation will allow more output signal before limiting, counterclockwise rotation will allow less. The limiter monitors the module’s output signal level, so increasing Gain will affect when limiting takes place. An LED indicates when the Limiter is active.
WARNING: Turn off power to unit and make all jumper selections before installing module in unit.
Priority Level*
This module can respond to 4 different levels of priority. Priority 1 is the highest priority. It mutes modules with lower priorities and is never muted. Priority 2 can be muted by Priority 1 modules and mutes modules set for 3 or 4. Priority 3 is muted by either Priority 1 or 2 modules and mutes Priority 4 modules. Priority 4 modules are muted by all higher priority modules. * The number of priority levels available is determined by the amplifier the modules are used in.

STICK-ON SERIES Model ST-MX2 双输入音频混音器说明书

STICK-ON® SERIESModel ST-MX2∙Two Input Audio Mixing∙Selectable Mic or Line Level Inputs∙Simultaneous Mic and Line Outputs∙Add Additional Inputs to an Existing Mixer∙Audio Output Dual-LED VU Metering∙Balanced or Unbalanced Inputs and Outputs∙Low Noise and Low Distortion PerformanceThe ST-MX2 is part of the group of versatile STICK-ON products from Radio Design Labs. STICK-ONs feature the advanced circuitry for whichRDL products are known, combined with unequalled versatility in mounting possibilities. The durable adhesives provided with the ST-MX2 permit permanent or removable mounting. Numerous available mounting accessories, brackets, rack-mount and tabletop chassis are optionally availableto facilitate any system. STICK-ONs are designed, built and rated for continuous duty in professional A/V systems.FUNCTIONAL DESCRIPTION: The ST-MX2 is a two channel audio mixer. Each input channel is identical. Pin jumpers adjacent to each audio input permit the installer to set that input for either mic or line level. The mic input accepts low impedance balanced microphones (150 Ω nominal) or high impedance unbalanced microphones(5kΩnominal). The line inputs are 20 kΩbridging and accept either unbalanced or balanced audio signals.A single-turn trimmer is provided for each input channel. The usual range of mic or line level signals may be adjustedto produce +4dBu at the line level output. The dual LED audio meter provides accurate dynamic level adjustment without an external meter. A separate mic level output is also provided.The dual LED output meter follows standard VU ballistics. A green LED illuminates at 15 dB below +4 dBu. The intensity of the green LED progresses from minimum at -11 dBu to full intensity at +4 dBu. The adjacent red LED illuminates at +4 dBu. The audio may be adjusted for maximum intensity of the green LED. Flashing of the red LEDis equivalent to a VU meter needle swinging above the 0 level.Unbalanced audio inputs are converted in the module to balanced. Mic level inputs are preamplified to line level. Either input may be turned down if it is not used. The combination of input levels, individual input adjustments and output levels makes the ST-MX2 suited to a wide variety of mixing, summing, preamplification and audio format conversion applications.TYPICAL APPLICATION: The ST-MX2 is used in any application requiring mixing of two audio sources. A mic maybe mixed with a line level music source. Two mics may be mixed to feed the mic or line level input of a power amplifier in a meeting room or choir loft. A mic or professional +4 dBu line level mono sum is possible from stereoCD players, cassette decks, computer sound cards, televisions, and a wide variety of other unbalanced sources. If asingle input channel is used, the ST-MX2 may be used to convert mono line level signals from consumer to professional, or from professional to consumer format. It may also be used as a microphone preamplifier, or conversely to adapt unbalanced or balanced line level signals into the microphone input of other equipment.The audio clarity, low noise, low distortion and versatility make this module ideally suited to a wide variety of demanding audio applications. Use this module individually, or in conjunction with other RDL modules as part of ahigh quality, flexible audio/video system.RDL ∙ 659 6th St. ∙ Prescott, AZ., USA 86301 ∙ (928) 443-9391 ∙ FAX (928) 443-9392 ∙STICK-ON® SERIES Model ST-MX2Universal Audio MixerTYPICAL PERFORMANCEInputs (2): Selectable mic or lineInput range for +4 dBu output:Mic: -45 dBu to -65 dBu; max input: -28 dBuLine: -18 dBV to +10 dBu max input: +22 dBu Input impedance: Mic: 200 Ω; Line: 20 kΩ bridgingInput or output configuration: Balanced or unbalancedOutputs (2): MIC and LINEOutput impedance: 150 Ω (mic or line)Frequency Response:Mic: 25 Hz to 50 kHz (± 1 dB)Line: 10 Hz to 30 kHz (± 0.25 dB)THD+N: Mic: < 0.05% (25 Hz to 20 kHz)Line: <0.005%IMD: <0.004% Output Level: Mic: -45 dBu; line: +4 dBu Headroom:Mic Input: > 22 dB (rel. –50 dBu)> 32 dB (rel. –60 dBu)Line Input: > 18 dB (rel. +4 dBu)Output: > 20 dB (rel. +4 dBu)Noise (below +4 dBu):Mic: < -70 dB (150 Ω source, 50 dB gain),< -80 dB (200 Ω source, 50 dB gain)Line: < -90 dB (reference +4 dBu, unity gain) CMRR:Mic: > 65 dB (50 Hz to 120 Hz)Line: > 45 dB (50 Hz to 120 Hz)Ambient Operating Environment: 0° C to 55° CPower Requirement: GROUND REFERENCED,24 Vdc @ 60 mAInstallation/OperationDeclaration of Conformity available from .Sole EMC specifications provided on product package.Specifications are subject to change without notice.891-1075CRadio Design Labs Technical Support Centers U.S.A.

态时，LED灯为闪烁状态，闪烁间隔时间约为0.5s；当蓝牙处于连接好状态时，LED灯为闪烁状态，闪烁间隔时间约为1s。 7、 BT_ON为蓝牙手动开关控制，BT_MFB为蓝牙多功能控制。IN2011S模组的固化软件默认为蓝牙自动连接，当模组设置为自动连接时，可不使用BT_ON、BT_MFB管脚。如果需要使用手动开关及配对时，一般将此两管脚连接在一起由同一个按键控制（见原理图）。此按键需要长按超过2s。BT_MFB短按触发时，作为控制音乐播放与暂停的功能。详细说明请参见设计文档AD202。 8、 IN2011S不支持音量调节功能，因而需要额外增加可调节通道音量大小的控制电路。详细说明请参见设计文档AD202。 9、 IN2011S支持UART串行接口控制，可通过串口对模组进行控制及状态检测。如果使用UART串口时，则无需使用其他按键硬线接口（BWD、FWD、BT_ON、BT_MFB、LED）。详细串口指令说明请参见设计文

VREFB管脚。
主要需要注意的有如下几点： 1、模组下方尽可能不要有任何走线，保持完整的GND接地铜皮。 2、 “VREF_OUT”管脚的输出需要先连接“VREFA”与“VREFB”的管脚滤波电容，然后再连接到
“VREFA”与“VREFB”的管脚，如下图所示。

3、模组尽可能放置在单板边缘，模组上的天线部分需要伸出单板边缘外，必须保证天线上方，下方均没有铜皮。如天线部分不能伸出单板边缘外，则需要将天线相应地方的单板挖空。如下图示意。
