Description

DA-4X4B Distribution Amplifier

 

Radio Systems’ DA-4x4b may be the best DA ever made. We’ve lowered the noise to a whisper at 102 dB below +4 dBm out with an internal toroidal transformer that dramatically reduces internal electrical interference fields. Distortion in the DA-4x4b is so low that it is hard to measure as a result of low noise op-amps and a careful design of the output amplifiers.

FEATURES

 

  • Versatile configurations- quad, stereo or mono
  • Front panel individual output level sets
  • Internal torroidal transformer
  • Super-low noise and distortion specifications
  • Individual rear panel removable I/O barrier strip connectors
  • 110/220 volt - CE certified
  • Front panel audio presence and overload LED indicators
  • Also available: DA-2x4b with stereo and mono configurations
