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.3

Main 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
