RDL RU-PA40D 40 W Stereo Audio Power Amp with VCA & Power Supply

Rs. 242.00

The RU-PA40D is the ideal choice in many applications where a high quality, high-efficiency utility amplifier is needed to drive a pair of 4 ohm or 8 ohm speakers. 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.

The 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.
