This item up for bid is a DOD SR460H Headphone Distribution Amplifier, sightly used and in excellent condition.
This amplifier accepts a stereo source which can be connected on the front, or rear panel, and delivers the signal to 6 headphone outputs. Each channel has its own level control and there is an overall master level. The SR460H has an "auto ramp" start up to protect your eardrums from the 1 watt of power delivered to each headphone output.
