The TOA M-61F exists for exactly that problem. It is a 900 Series microphone input module built around the same transformer-balanced 600-ohm front end and female XLR jack as TOA's standard mic modules, with a built-in compressor added on board. Once the input signal crosses an adjustable threshold the module clamps down at a fixed 2:1 ratio - every 2 dB of extra input yields only 1 dB more output - so loud talkers, plosives and handling noise stop driving the amplifier into overload and distortion.\u003c\/p\u003e\u003cp\u003eThe threshold is set with a screwdriver trim at commissioning: turning it clockwise lowers the threshold so compression starts earlier on quieter signals, counter-clockwise raises it so only genuinely hot inputs are caught. The adjustable threshold range spans -66 to -46 dB, with a specified signal muting level of 20 dB. Alongside the compressor sit the fixed low- and high-cut filters at 330 Hz and 4.2 kHz, both at 6 dB per octave, which trim HVAC rumble and harshness before they reach the mix bus. Phantom power at +22 V DC is active by default for condenser microphones and is disabled by cutting jumper J1 on the module.\u003c\/p\u003e\u003cp\u003eThe M-61F installs like every other 900 Series card: it seats in any of the eight input ports on the A-903MK2, A-906MK2 and A-912MK2 mixer power amplifiers or the M-900MK2 mixer preamplifier, in the W-906A and W-912A in-wall mixer power amplifiers, in the two 900 Series module slots of the 800D Series digital mixer amplifiers A-812D, A-824D and A-848D, and in TOA's 9000M2 Series amplifiers, which accept existing 900 Series input modules. It draws 33 mA from the host frame's 24 V DC rail. Specify the M-61F for lecterns, courtrooms, council chambers, gymnasiums and any paging microphone the public will actually touch.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMicrophone input module with on-board compressor for TOA 900 Series mixer\/amplifiers\u003c\/li\u003e\n\u003cli\u003eCompressor prevents overload and distortion when input exceeds a preset threshold\u003c\/li\u003e\n\u003cli\u003eFixed 2:1 compression ratio - output rises 1 dB for every 2 dB of input increase\u003c\/li\u003e\n\u003cli\u003eAdjustable threshold control sets when compression engages\u003c\/li\u003e\n\u003cli\u003eHigh-cut and low-cut filters at 4.2 kHz and 330 Hz, 6 dB\/octave\u003c\/li\u003e\n\u003cli\u003e+22 V DC phantom power active by default; disabled by cutting jumper J1\u003c\/li\u003e\n\u003cli\u003eTransformer-isolated 600-ohm balanced input on a female XLR connector\u003c\/li\u003e\n\u003cli\u003eFits A-903MK2, A-906MK2, A-912MK2, M-900MK2, W-906A, W-912A, the 900 Series module slots on the A-812D \/ A-824D \/ A-848D, and 9000M2 Series amplifiers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModule type: Balanced microphone input module with compressor (900 Series)\u003c\/li\u003e\n\u003cli\u003ePower supply: 24 V DC (supplied from the main frame)\u003c\/li\u003e\n\u003cli\u003eCurrent consumption: 33 mA\u003c\/li\u003e\n\u003cli\u003eInput sensitivity: -60 dB (0 dB = 1 V), rated output -20 dB; adjustable -72 to -52 dB\u003c\/li\u003e\n\u003cli\u003eInput impedance: 600 ohms, balanced, transformer-isolated\u003c\/li\u003e\n\u003cli\u003eFrequency response: 25 Hz - 20 kHz, ±1.5 dB\u003c\/li\u003e\n\u003cli\u003eDistortion: 0.1% or less (1 kHz, output -60 dB)\u003c\/li\u003e\n\u003cli\u003eNoise level: -86 dB (20 Hz - 20 kHz BPF); input-equivalent noise -126 dB\u003c\/li\u003e\n\u003cli\u003eGain: 32 - 52 dB\u003c\/li\u003e\n\u003cli\u003eTone control: 100 Hz, 0 to -10 dB; 10 kHz, 0 to -10 dB\u003c\/li\u003e\n\u003cli\u003eCompression ratio: 2:1 (fixed)\u003c\/li\u003e\n\u003cli\u003eSignal muting level: 20 dB (threshold-adjustable input level -66 to -46 dB)\u003c\/li\u003e\n\u003cli\u003ePhantom power: +22 V DC (for condenser-type microphones)\u003c\/li\u003e\n\u003cli\u003eConnector: Female XLR (XLR-3-31 equivalent)\u003c\/li\u003e\n\u003cli\u003eModule dimensions: 35 (W) x 78 (H) x 88 (D) mm \/ 1.38\" x 3.07\" x 3.46\"\u003c\/li\u003e\n\u003cli\u003eModule weight: Max. 110 g (0.24 lb)\u003c\/li\u003e\n\u003cli\u003eShipping weight: 0.2646 lb\u003c\/li\u003e\n\u003cli\u003eShipping carton: 3.54\" x 3.74\" x 1.57\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1x TOA M-61F microphone input module with compressor and female XLR connector\u003c\/li\u003e\n\u003cli\u003eNo additional accessories are specified by TOA for this module\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOA Electronics","offers":[{"title":"Default Title","offer_id":46588278505669,"sku":"TOA-M61F","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/M-61F_Angle.jpg?v=1784921351","url":"https:\/\/avlgear.com\/products\/toa-m-61f-mic-input-module-with-compressor-female-xlr-900-series","provider":"AVLGEAR","version":"1.0","type":"link"}
