4-710D Four-Channel “Twin-Finity” Mic Preamp & DI with Compressor The 4-710D is a modern 4-channel preamp with roots back in time, featuring 4 of the award-winning 710 Twin-Finity mic preamp with both transistor and tube, allowing you to seamlessly mix tube and transistor-based sound.
But the 4-710D is much more than that… Each mic channel is equipped with a newly designed 1176-style compressor/soft limiter for dynamic control.
If you use the built-in A/D digital conversion, you get access to 4 extra inputs.
A total of 8 channels of 24-bit, 192 kHz A/D conversion with both ADAT and AES/EBU output (DB25).
This makes the 4-710D ideal as an add-on to, for example, one of Universal Audio’s Apollo interfaces and complements Apogee Symphony or Avid HD/HDX systems.
The microphone channels naturally also have analog outputs – separate and balanced, and are also equipped with balanced insert send/returns so you can add EQ or effects to the signal path. SpecificationsPreamplifiers
