The Auteur 8DAT is an eight-channel microphone preamplifier and A/D converter designed to expand interface setups via ADAT. The unit combines the company's signature high-speed transparent preamplification with integrated digital conversion, offering a solution for tracking full drum kits or large ensembles within a single rack unit.

The Auteur 8DAT features eight channels of Chicago-style transformer-coupled preamps. The first two channels include front-panel Hi-Z inputs for direct instrument tracking. Each channel is equipped with a dedicated gain control, polarity flip, 10dB pad, and 48V phantom power. The analog circuit is designed to provide a wide frequency response and low noise floor, while the IC-based input stages ensure rapid transient response.

For digital integration, the unit utilizes high-quality A/D converters capable of resolutions up to 24-bit/192kHz. Connectivity is handled via dual ADAT Optical outputs, allowing for full eight-channel counts even at higher sample rates (S/MUX). The unit also includes a Word Clock I/O for synchronization with external digital clocking systems.
