It is specifically suited to amplification applications where users need to adjust the gain. Examples include projectors or monitors with fixed audio outputs used in classrooms, boardrooms or video conferencing. The RU-PA40D is ideal for foreground sound amplification in small to medium rooms or in a specific zone within a retail space.\u003c\/p\u003eThe RU-PA40D features two balanced line-level inputs on a detachable terminal block. Two unbalanced line level inputs are available on high-reliability gold plated phono (RCA) jacks. A front-panel gain control trimmer permits setting the maximum gain for each channel. The gain range accommodates the range of typical balanced and unbalanced audio signal levels. Each of the two RU-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.The RU-PA40D is equipped with an internal stereo VCA for setting the output level on both amplifier channels. A detachable terminal block provides for the connection of an external 10 K ohm potentiometer or a 0 to 10 Vdc control voltage. RDL remote controls are available to provide single-turn, multi-turn (rotary encoder) or pushbutton (ramp or fixed level selection) user level control. VCA control insures long term noise-free level adjustment. Remote control is possible using audio, control or common computer network wire.\u003cul\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cli\u003eVCA Controlled 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\u003eUnbalanced RCA Jack Inputs Balanced Detachable Terminal Block Inputs \u003c\/li\u003e\n\u003cli\u003eVCA Control on Detachable Terminal Block\u003c\/li\u003e\n\u003cli\u003eExternal Control Using 10 K ohm Potentiometer or 0 to 10 Vdc\u003c\/li\u003e\n\u003cli\u003eCompatible with RDL Remote Level Controls\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\u003eHigh-Efficiency Class D Operation\u003c\/li\u003e\n\u003cli\u003eThermal and Short-Circuit Protection\u003c\/li\u003e\n\u003cli\u003eRU-PA40D includes North American Cord RU-PA40DE excludes Power Cord\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":48414385876,"sku":"237820","price":242.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1203\/4576\/products\/683c26bee1badec4faecb80b5bdf9ef1.jpg?v=1502886289","url":"https:\/\/sg-2111.myshopify.com\/products\/rdl-ru-pa40d-40-w-stereo-audio-power-amp-with-vca-power-supply","provider":"SG_2111","version":"1.0","type":"link"}
