Stereo Audio Line Pre-Amplifier
Calrad's compact stereo pre-amplifier is ideal for audio distribution systems where sources may have different output levels. The small size and attached mounting tabs make it easy to install the amplifier in the wall, directly behind video displays or in equipment racks. The output and input are L+R RCA jacks. Adjustable volume control. Adjust the pre-amp gain so your source is matched with the others before entering your distribution or zone amps.
