Pro Audio 400 | DIGI-SYS

General Detail:

DIGI-SYS PRO AUDIO DA 400 is a Professional audio distribution amplifier, designed to economically distribute the audio signals in a broadcast station or a recording studio. The PRO AUDIO DA 400 can effectively feed to various destinations the same source with transparent quality. The active output configuration allows the inputs and outputs patched freely through patching panel and drive long lines without interference.

DIGI-SYS PRO AUDIO DA 400 has excellent frequency response and very low distortion, which has been achieved by selectively using integrated circuits and discrete devices. Extremely low noise levels are achieved by eliminating hum at all stages and using low noise devices. There is an individual gain control to give ±5dB level adjustment. The unit is housed in a 19” rack mount chassis with power connections as per IEC recommendation.
