RA53 Stereo Headphone Amplifier Connection Schematic

This stereo headphone amplifier device may provide up to ten channels of headphone monitoring if a 1/4” Link Input/Output jack is provided for connecting two RA53 units together. The schematic below illustrates a possible operation for this RA53 stereo headphone amplifier.

As you can see, the headphones are connected to the outputs on the front panel side, when the others to the rear panel. Another connection possibility can be:

1. The Left and Right Inputs to the RA53 are connected to the mixer’s sub outputs, but could be connected to auxiliary sends or even main outputs.
2. The RCA Auxiliary Inputs are connected to a playback deck.
3. For individual monitoring, a stereo TRS connector could be plugged into a stereo
auxiliary send from the mixer to an Insert jack on the RA53. This way, different
material may be monitored on Channels 1 and/or 2 than that of the main inputs.
