MOTU 624 Thunderbolt / USB-3 / AVB Ethernet Audio Interface with DSP and Mixing

The MOTU 624 represents a versatile 16 x 16 audio interface compatible with Thunderbolt, USB, and AVB connections, offering console-style mixing capabilities across 48 channels. It boasts DSP effects, wireless control, and AVB audio networking, along with exceptional A/D/A conversion quality supporting sample rates up to 192 kHz, ideal for mobile audio recording needs. Its robust DSP enables expansive mixing possibilities, featuring 48 channels, 12 stereo busses, and 32-bit floating point effects processing, encompassing modeled analog EQ, vintage compression, and classic reverb. With matrix routing functionality, users can efficiently route inputs to outputs or split inputs across various destinations. The 624 is designed to function as an audio interface for studio workstations (DAWs), a standalone mixer, or as an auxiliary monitor mixing system both in studio setups and on stage.

Features:
