BALANCING AND DE-BALANCING
INFORMATION AND SPECIFICATIONS

 
Balance 8™ / 8 channel Audio Balancer / Level Optimizer

Applications

  • Studio, Live Sound and Broadcast
  • Patch Bays
  • AV Systems/CD/VIDEO
  • Anywhere unbalanced signals need converting to professional balanced signals
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 has introduced 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 LED’s on the front panel indicate which mode has been selected.

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

Applications

  • Studio, Live Sound and Broadcast
  • Patch Bays
  • AV Systems/CD/VIDEO
  • Anywhere professional balanced signals need converting to un-balanced signals
Innovation
Sooner or later there comes a time when Pro Audio Balanced outputs need to be converted to Unbalanced, to silently interface with the -10dB unbalanced inputs of consumer electronics. Distortion and noise from a mismatch at this point will be amplified throughout the system. Now there’s a simple and straightforward solution to this problem – the all-new ARX DeBalance 8, an 8 channel audio Debalancer and Level Optimizer specifically designed to handle this critical task.

ARX’s proprietary debalancing circuits take the Balanced +4dB levels from professional audio systems and effortlessly convert them into the unbalanced signals that all units with unbalanced inputs need, such as LCD, LED and plasma screens and other consumer-type products Inputs are industry standard balanced 3 pin XLR type, and outputs are unbalanced RCA connectors.

Pairs of Gain Mode switches on the front panel let you select unity gain through the DeBalance 8, using it as a debalancer only, or as a level optimizer as well, bringing the +4 dB levels down to –10 dB (–14dB overall loss). Status LED’s on the front panel indicate which mode has been selected.

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