The TEYUN Q24 is a 2‑input / multiple‑output USB audio interface (sometimes marketed as “sound card + interface”) for computers.

Audio resolution / Sample rate
24‑bit / 192 kHz A/D & D/A conversion
Inputs
• 2 × MIC/LINE combo inputs (XLR or ¼” TRS) — for mics, instruments, line‑level signals • Additional stereo RCA input (L/R) for line‑in sources (e.g. external audio player, mixer, keyboard)
Instrument (Hi‑Z) support
HI‑Z mode available on Input 1 — for direct connection of guitars/bass without DI box
Outputs
• 2 × ¼” TRS Main Outputs (Left & Right) — for studio monitors / speakers • Stereo RCA line‑out (L/R) • ¼” TRS Headphone output — with independent volume control
Phantom Power
+48 V switchable +48 V phantom power — for condenser microphones on either input.
Loopback Function
Yes — “loopback” / internal routing option for capturing playback + input (useful for streaming or capturing computer audio along with mic/instrument)
Connection / Interface
USB 2.0 (USB‑B port) — connects to PC/Mac for power and data; optionally accepts external 5 V DC power if USB bus power is insufficient.
Monitoring & Controls
Front‑panel controls include: — Gain knobs for each input — Signal (SIG) and Peak meters per input — “Mix‑DAW / Input” knob (to adjust direct‑input vs DAW playback monitoring mix) — Output volume knob (main) and Phones volume knob — 48 V phantom power button + power LED — Loopback button — HI‑Z switch, Mono/Stereo switch.
Frequency Response (Input/Output)
20 Hz – 20 kHz (± ~0.1–0.5 dB) — flat enough for full‑range audio including vocals, instruments, general mixing.
Dynamic Range / Noise / Distortion
Dynamic range ~ 100 dB (A‑weighted) for inputs/outputs, THD+N (total harmonic distortion plus noise) < 0.001% (per manufacturer spec) for clean signal path.
Impedance & Max Levels (Typical / per spec sheet)
- Microphone input impedance ~ 2.2 kΩ - Line‑level / instrument input impedance higher (suitable for guitars/instruments via HI‑Z) - Output impedance for main outputs: ~100 Ω, suitable for studio monitors.
Build / Power
Metal chassis, compact form‑factor. Powered via USB (bus power) or optional 5 V DC external adapter — useful if phantom power + demanding inputs cause USB power constraints.
Compatibility
Works plug‑and‑play on Windows and macOS; many DAWs accept it natively. Loopback + RCA inputs also can make it work with mixers, keyboards, media players, etc.
