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

The 4-710d is four channels of the Twin-Finity idea in one rack unit: each channel blends a tube path with a solid-state path and carries its own 1176-style FET compressor, so a drum kit or a horn section can be tracked with dynamics and character already committed.

Eight analog inputs are digitized by 24-bit A/D converters at selectable sample rates up to 192 kHz and sent out over ADAT optical, which is the straightforward way to add eight inputs to an Apollo interface without another set of preamps.
