Q24

This 2-inch and 4-out USB audio interface is an entry-level professional sound card designed specifically for recording, live streaming, instrument playing, home karaoke, and other scenarios. Adopting 24bit/192kHz high-resolution audio processing technology, supporting multiple types of inputs such as microphone, instrument, and circuit, providing dual-mode output for headphones and speakers, integrating low latency monitoring, independent volume control, 48V phantom power supply, and other functions. It is driver free plug and play, providing stable and high fidelity signal processing solutions for audio creation and sharing.

Core Technologies & Performance Highlights

1. High-Resolution Audio Processing, Restoring Professional Sound Quality

Sampling Specifications: 24bit/192kHz high sampling rate, far exceeding CD audio standards, capturing richer audio details with a wider dynamic range;

Frequency Response: 20Hz~20kHz (±1dB), fully covering the human-audible frequency range with rich bass, transparent midrange, and clear treble, without frequency coloration;

Dynamic Range: 82dB (A-weighted), with a signal-to-noise ratio of up to 85dB, extremely low noise floor, and clean, noise-free background, meeting studio-grade monitoring requirements;

Distortion Control: Total Harmonic Distortion + Noise (THD+N) is only 0.03% @1kHz, with almost no distortion during signal transmission and processing, restoring vocals and instrument sounds truthfully and naturally;

Wide Gain Adjustment: Microphone gain range of +3dB~+60dB, compatible with different input devices such as dynamic microphones, condenser microphones, and instruments, allowing flexible adjustment of signal strength.

2. 2-In 4-Out Multi-Interface Signal Processing

Dual Input Channels: Equipped with 2 XLR/TRS combo input interfaces, supporting three input modes: Microphone (MIC), Line (LINE), and Instrument (HI-Z). Can connect 2 microphones simultaneously or 1 microphone + 1 instrument;

Four Output Channels: Provides headphone monitoring output, dual RCA outputs, and dual 6.35mm main outputs. Can connect headphones, monitor speakers, amplifiers, and other devices at the same time, meeting multi-scenario output needs for monitoring, sound reinforcement, and recording;

Independent Channel Control: Each input channel is equipped with an independent gain knob and peak/signal indicator light, allowing precise adjustment of the volume of each signal to avoid signal overload and distortion;

Low-Latency Monitoring: Supports direct monitoring mode, where microphone/instrument signals can be transmitted directly to headphones without computer processing delay, suitable for real-time singing and instrument performance.

3. Practical Function Design for Multi-Scenario Needs

Driver-Free Plug-and-Play: Compatible with mainstream systems such as Windows and macOS, no driver installation required, works with computers out of the box, beginner-friendly;

48V Phantom Power: Supports 48V power supply for condenser microphones, one-click activation to drive condenser microphones, compatible with studio-grade microphones;

Loopback Recording Function: Supports mixed internal recording of computer audio and microphone signals, allowing simultaneous recording of vocals and accompaniment, suitable for live streaming, karaoke recording, game voice chat, and other scenarios;

Mono/Stereo Switching: Can switch signal modes. Mono mode is suitable for multi-person monitoring or mono source processing, while stereo mode retains full channel separation effects, ideal for music creation scenarios;

Ground Loop Elimination Design: Equipped with a ground terminal to eliminate current noise generated by device connections, improving audio purity.

4. Stable Power Supply & Portable Design

USB/DC5V Dual Power Supply: Supports power supply via USB2.0 interface or external DC5V power adapter, providing stable power for long recording or live streaming sessions;

Lightweight Body: Weighs only 0.8kg, with a durable metal casing for strong anti-interference capability. Compact size allows easy portability, suitable for mobile recording, outdoor live streaming, and other scenarios.

User-Friendly Design & Operation Layout

1. Clearly Partitioned Front Panel

Input Control Area: Equipped with GAIN 1/GAIN 2 gain knobs, paired with PEAK (peak) and SIG (signal) indicator lights for intuitive signal status monitoring;

Mode Switches: HI-Z (instrument high impedance) and MONO (mono) switches, one-click adaptation to different input devices and signal modes;

Monitoring Control Area: INPUT-MIX-DAW knob adjusts the monitoring ratio of input/computer signals, OUTPUT knob controls main output volume, and PHONES knob controls headphone monitoring volume;

Function Buttons: Loopback recording switch and 48V phantom power switch, with clear status indicators showing working status.

2. Rear Panel Interface Layout

Power & Data Area: USB2.0 interface (connects to computer), DC5V power interface, +48V power switch, and ground terminal;

Input/Output Area: RCA inputs (L/R), RCA outputs (L/R), and dual 6.35mm main output interfaces, arranged in separate sections for convenient wiring.
