UNIVERSAL AUDIO 4-710D Four-Channel Mic Preamp with Dynamics

The UNIVERSAL AUDIO 4-710D Four-Channel Mic Preamp with Dynamics is a premium multi-channel recording front-end that combines four award-winning 710 Twin-Finity™ microphone preamps, integrated 1176-style compression, and high-quality 24-bit/192kHz A/D conversion into a single professional rack unit. Designed for recording studios, producers, engineers, and musicians, the 4-710D delivers exceptional tonal flexibility, allowing users to seamlessly blend classic tube warmth with modern solid-state clarity. (Universal Audio)

At the heart of the 4-710D are four independent Twin-Finity™ preamp channels, each featuring dual signal paths: a high-voltage Class-A tube circuit and a discrete solid-state circuit. Using the unique Tone Blend control, users can continuously adjust between 100% tube, 100% solid-state, or any combination in between, providing a vast range of sonic textures from transparent and clean to rich, harmonically saturated analog tones.

Each channel also includes dedicated 1176-style compression circuitry, offering fast and musical dynamic control directly during recording. With selectable Fast and Slow compression modes and true bypass functionality, the compressor section is ideal for vocals, bass guitars, drums, acoustic instruments, and other dynamic sound sources.

Beyond its analog capabilities, the 4-710D features eight channels of professional A/D conversion with selectable sample rates up to 192kHz. The unit provides digital connectivity via dual ADAT optical outputs and AES/EBU, making it an excellent choice for expanding the input count of audio interfaces and digital recording systems. Four additional rear-panel line inputs further enhance flexibility for hybrid studio workflows. (Perfect Circuit)

Designed for demanding recording environments, the 4-710D includes large illuminated VU meters, phantom power, polarity reverse, low-cut filtering, insert points, high-impedance DI inputs, and up to 70dB of gain per channel. Its combination of analog character, dynamic control, and digital integration makes it one of the most versatile microphone preamps in Universal Audio's hardware lineup. (Musician's Friend)
