Interspace PCBB²

Being completely passive (no batteries or external power required) and bi-directional, PC Balance Box can match unbalanced and balanced audio sources, line to mic levels, stereo and mono signals, and troubleshoot hum problems – all in one versatile and rugged unit. The PC Balance Box is the simplest way to interface unbalanced computer or consumer audio signals to balanced AV sound systems. The inputs and outputs are completely isolated in either direction and by using the ‘Ground Lift’ feature where required, hum problems can be easily cured.
