audio interface

Interfaces and portable DACs use a mix of headphone outputs: single‑ended 3.5 mm (including S‑Balanced variants), larger 6.3 mm TRS, and balanced 4.4 mm jacks. Reported maximum headphone power for some models ranges around 390 mW up to about 477 mW (specs vary by unit), so output type and power depend on the specific model.

Many interfaces feature transparent preamps with high gain — for example, Crystal preamps offering up to 55 dB of gain — and switchable +48V phantom power to support studio condenser microphones.

Some units provide zero‑latency (direct) monitoring for real‑time performance, while others offer dedicated headphone monitoring with independent blend/mix controls so performers can create tailored headphone mixes during tracking and mixing.

Bundles commonly include headphones, microphones, XLR and TRS cables, mic mounts or stands, and software packages such as DAW starter editions and instrument/preset libraries. These packs are designed to provide basic cables, monitoring, and entry‑level recording software for beginners.
