    About this Product

    Balance box and hum eliminator for taking audio out of a presentation PC. Hum is not just a long-cable problem, power supplies, lighting and neighbouring equipment all inject noise into an unbalanced input. This box breaks the loop with no compromise on bandwidth, holding 20Hz to 20kHz, and adds a plug-and-socket input over the earlier PCBB3.
