At the heart of the 4-710d are four channels of "Twin-Finity" mic preamps, allowing you to blend between 100% tube and 100% solid-state signal paths. This flexibility lets you craft a wide range of tones—from smooth and creamy to edgy and crunchy—by dialing in just the right balance of tube warmth or solid-state clarity.
Each channel also includes true-bypass 1176-style compression, with "fast" and "slow" settings for quick adjustments. This makes it easy to add thickness to vocals, keep a bass guitar steady, or enhance the texture of synths and horns with a bit of extra grit or sheen.
With eight analog inputs, the 4-710d is a great way to expand your studio setup. Its 24-bit A/D converters, with selectable sample rates up to 192 kHz, ensure high-quality digital conversion. Plus, it easily integrates with most interfaces through dual ADAT optical or AES/EBU DB-25 connectors.
PSU works on 100-240V, EU power cord included.
