Now shipping, the Universal Audio 4-710d Four-Channel "Twin-finity" Mic Preamp and DI with Dynamics is the newest piece of equipment to join the company's line of analog hardware. The flexible 4-710d preamp combines boutique-quality tube and solid-state tones with modern features such as tone-blending, dynamics, and digital outputs.

At the heart of the 4-710d are four channels of tone-blending "Twin-finity" mic preamps with true-bypass 1176-style compression, along with four additional line inputs feeding eight channels of analog-to-digital conversion. This new unit is based on the original 710 "Twin-Finity" preamp, and each of the four mic preamp channels allows for continuously variable tone between 100 percent tube and 100 percent solid-state signal path. Send and return jacks are available for external processing or signal access.

The eight analog inputs are digitized via 24-bit A / D converters at selectable sample rates up to 192 kHz. Digital output is available via dual ADAT "lightpipe" or AES / EBU DB-25 connectors, facilitating integration with most popular audio interfaces. Check out the rest of the 4-710d's features:
