The 4-710d from Universal Audio is a high-end, 4-channel microphone/line preamplifier with tube and solid-state tone blending capabilities. The dual signal path is perfect for a wide range of microphone and instrument sources, with each channel offering selectable 1176-style compression circuitry. Four additional line inputs feed 8-channels of pristine analog-to-digital conversion. The 1176-style compression include specially tuned "fast" and "slow" settings, and can be completely switched out of the signal chain.

Each of the microphone 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 8 analog inputs are digitized via ultra high-quality 24-bit analog to digital converters at selectable sample rates up to 192kHz. Digital output is available via dual ADAT Lightpipe connectors (SMUX supported), or via a 25-pin D-sub connector for 8-channels of AES/EBU, allowing for easy integration with most popular audio interfaces.
