It is specifically suited to fixed-gain amplification applications where gain is controlled by other equipment. Examples include projectors with variable audio outputs used in classrooms, boardrooms and video conferencing.\u003c\/p\u003eThe TX-PA40D features two unbalanced line level inputs on high-reliability gold plated phono (RCA) jacks. A front-panel recessed gain control trimmer permits setting the desired amplifier output level for each channel. The gain range accommodates the range of typical unbalanced audio signal levels. Each of the two TX-PA40D outputs will drive a 4 ohm or 8 ohm speaker or multiple speakers connected to present a 4 ohm or 8 ohm load to the amplifier. The output impedance is switch-selectable on the front panel of the module.A front-panel switch is provided to sum the audio inputs to mono. In the \u003cstrong\u003eSTEREO\u003c\/strong\u003e mode, the TX-PA40D independently amplifies each audio channel, left (\u003cstrong\u003eL\u003c\/strong\u003e) and right (\u003cstrong\u003eR\u003c\/strong\u003e). If speaker placement in the specified installation is incompatible with stereophonic amplification, the \u003cstrong\u003eINPUT MODE\u003c\/strong\u003e switch may be set to \u003cstrong\u003eSUMMED MONO\u003c\/strong\u003e. \u003cul\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cli\u003e Stereo Audio Power Amplifier\u003c\/li\u003e\n\u003cli\u003e20 Watts RMS per Channel into 8 ohm “ 40 Watts Total\u003c\/li\u003e\n\u003cli\u003e15 Watts RMS per Channel into 4 ohm “ 30 Watts Total\u003c\/li\u003e\n\u003cli\u003eLeft and Right Unbalanced Phono Jack Inputs\u003c\/li\u003e\n\u003cli\u003eSwitch-Selectable Stereo or Mono Operation\u003c\/li\u003e\n\u003cli\u003eStudio Quality, Aurally Transparent Compressor\/Limiter\u003c\/li\u003e\n\u003cli\u003eCompressor\/Limiter Controls Clipping\u003c\/li\u003e\n\u003cli\u003eCompressor Produces Maximized Average Output Power\u003c\/li\u003e\n\u003cli\u003eCompression Enabled Using Input Level Adjustments\u003c\/li\u003e\n\u003cli\u003eLED to Indicate Audio Compression Threshold\u003c\/li\u003e\n\u003cli\u003eOutputs Drive 4 or 8 Ohm Speakers\u003c\/li\u003e\n\u003cli\u003eHigh-Efficiency Class D Operation\u003c\/li\u003e\n\u003cli\u003eThermal and Short-Circuit Protection\u003c\/li\u003e\n\u003cli\u003eTX-PA40D includes North American Cord TX-PA40DE excludes Power Cord\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":48414525844,"sku":"200468","price":218.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1203\/4576\/products\/c4eecfcaffae945d4ea6a275835ad07e.jpg?v=1502886457","url":"https:\/\/sg-2111.myshopify.com\/products\/rdl-tx-pa40d-40-w-stereo-audio-power-amplifier-with-power-supply","provider":"SG_2111","version":"1.0","type":"link"}
