Description

Stereo PC sound cards inherently suffer with buzz and hum problems when connecting to professional PA systems. The PC Bal Box will isolate and "clean up" the sound quality. We have the obligatory ground Lift switch as well as a stereo to mono switch. A Pad switch (of about 20dB) to bring the normal high level output of computer systems to a more normal level - we have Left and Right out so phase errors can be isolated as well as hearing pure stereo. As this is passive it will also work in reverse and act as a method to record external stereo or mono signals on to devices that need a 3.5mm (mini) jack input.
