INTRODUCTION
Congratulations, and thank you for your purchase of the DOD SR 460 Stereo Headphone Amplifier. The SR 460
provides you with Left, Right and Stereo inputs, and 6 outputs. In addition, each output has independent level
control as well as a master level for all 6 channels. Another unique feature to the SR 460 is its slow audio ramp-
up feature. The audio has an approximate 750 millisecond ramp-up time on power-up to prevent damage to
hearing caused by loud audio pops. It also gives you time to turn down the volume if previous settings are too
loud. All inputs and outputs are 1/4 inch TRS
The SR 460 is another innovative product brought to you by DOD Electronics.
