    At the core of the 4-710d are four channels of tone-blending Twin-Finity mic preamps with true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. Each of the four mic preamp channels allows for continuously variable phase-aligned tone, between a 100% tube and 100% solid-state signal path. Send and return jacks are available for external processing or signal access.

    The eight analog inputs are digitized via ultra high-quality 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.
