APHEX 120A

SINGLE CHANNEL DISTRIBUTION AMP

APHEX 120A DISTRIBUTION AMP
   One signal in, 4 signals out, all servo balanced XLR connectors with individual level controls.

   The Model 120 is a high performance audio distribution amplifier with a single high impedance input and four low impedance outputs, all electronically servo-balanced. The 120's transformerless circuits are designed for wide, flat frequency response free from ringing or overshoot, making it ideal for distribution of SMPTE time code as well as audio. Each output has its own amplifier and level control for maximum versatility and isolation. The sturdy steel chassis may be used stand-alone or rackmounted, singly or in pairs.
