ARX Balance 8, 8 channel Audio BalancerLevel Optimizer

Innovation
Silently interfacing -10dB unbalanced consumer electronics with +4 dB Balanced professional equipment has always been a problem. Hum and noise generated by a mismatch at this point will be amplified throughout the studio, broadcast or live sound system.

But luckily it’s a problem of the past, now that ARX introduces the Balance 8, an 8 channel audio balancer and level optimizer specifically designed to handle this critical task.
ARX’s proprietary balancing circuits take the -10dB levels from CD players, cassette and tape players, DAT recorders, digital 8 track recorders, and effortlessly transform them into the balanced signals that all professional audio systems expect.
Inputs are unbalanced RCA connectors, and outputs are industry standard balanced 3 pin XLR type.
Pairs of Gain Mode switches on the front panel let you select unity gain through the Balance 8, using it as a balancer only, or as a level optimizer as well, bringing the -10 dB levels up to +4 dB (14dB overall gain). Status LEDs on the front panel indicate which mode has been selected.

Housed in a rugged all steel chassis with extruded aluminium front panel, the ARX Balance 8 is the ideal professional engineer’s tool for the critical task of impedance and level converting.
