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. The unit has 4 isolated sections which can be easily wired and configured on a stereo 2x8, quad 4x4, or mono 1x1 DA. Each section features its own input LED and is an overload indicator and each output has its own level set, front panel attenuator.
19 inch (EIA rack mount) wide x 1.75 inches (1ru) high x 7.75 inches deep (with connectors).
