Universal Audio 4-710d Four-Channel Tone-Blending Mic Preamp

The 4-710d combines four 710 Twin-Finity mic/line preamps with 1176-style compression and an eight-channel A/D converter in a two-space rack unit. Each preamp has a dual-path 285 V Class A tube and transimpedance solid-state circuit, and the two paths can be blended continuously, phase-aligned, from 100% tube to 100% solid state for tones from creamy to crunchy.

Each channel has a true-bypass 1176-style compressor with "fast" and "slow" settings, a JFET direct input with 2.2 MOhm impedance, 48 V phantom power, 75 Hz low-cut filter, polarity switch and balanced inserts. Eight analog inputs are converted at 24 bit with sample rates up to 192 kHz and sent out via dual ADAT optical and AES/EBU DB-25 connectors, making it easy to add eight inputs to an Apollo or other interface.
