The PCBB3 PC Balance Box eliminates ground loop hum when connecting audio from your presentation PC or laptop to a professional AV sound system. It is completely passive and bi-directional.
Hum and noise can come from anywhere – power supplies, fluorescent lighting, other nearby equipment – all of which can cause interference that gets picked up by your audio input cables.
Being completely passive (no batteries or external power required) and bi-directional, the PC Balance Box can match unbalanced and balanced audio sources, convert line to mic levels, interface stereo and mono signals, and troubleshoot hum problems – all in one versatile, rugged unit.
The PCBB3 is the simplest way to interface unbalanced computer or consumer audio signals with balanced AV sound systems. Inputs and outputs are completely isolated in either direction, and with the built-in Ground Lift switch, hum problems can be cured instantly.
