audio mixer recorder

Most units offer a mix of analog and digital I/O: XLR and XLR‑1/4" combo mic/line/Hi‑Z inputs, TRS analog line inputs/outputs, RCA (phono/line) inputs and master outputs, plus digital formats such as AES/EBU, S/PDIF (coax and optical/TOSLINK), ADAT, and computer connections like USB and Thunderbolt.

Monitoring options range from a single headphone output to dual headphone outputs with independent level controls or split‑cue. Some devices include dedicated headphone D/A converters and zero‑latency monitoring paths; certain bundles even include over‑ear studio headphones for immediate monitoring.

Some devices offer standalone or live‑capture features such as built‑in MicroSD slots for direct recording/playback, RCA 'Rec' outputs for feeding an external recorder, and software/firmware functions for remote control and backup recording.

Sizes and weights vary widely: compact desktop units typically weigh about 1.0–4.7 lb, while larger rack or console systems can be around 17–21 lb. Footprints range from small desktop enclosures to multi‑inch rack or console formats.

Channel counts span from simple 2‑in/2‑out interfaces to large multi‑I/O systems. Examples in this selection include 2‑in/2‑out units, 4‑input/14‑I/O desktop units, systems with 32 inputs and 34 outputs (66 channels total), and listings up to 64 analog inputs and 64 analog outputs.

Most listings advertise professional operation such as 24‑bit/192 kHz. Several devices highlight 32‑bit floating‑point internal processing for mixing/effects, and some converter specs reference 24‑bit at 96 kHz.
