Features:
1. Utilizes a DSP-based processing system; each channel features dozens of built-in filter points for automatic dynamic scanning and high-precision filtering, effectively suppressing audio feedback and howling while preserving the natural sound quality of vocals and instruments.
2. Features an automatic threshold-based limiter design to prevent distortion caused by signal overload or equipment damage from excessive levels. When input volume is too high, the limiter automatically adjusts sound pressure to protect the speaker system and gradually releases the limiting effect once volume returns to normal, ensuring safe operation.
3. Equipped with independent channel gain knobs and clear LED level indicators, allowing for intuitive, individual volume adjustment for each channel based on the venue environment and microphone input signals.
4. The rear panel features professional XLR and 6.35mm combo input jacks (compatible with various sources such as wired/wireless microphones) and independent XLR and 6.35mm dual-channel output jacks, ensuring highly stable signal transmission with low latency.
5. Suitable for installation in standard professional racks (approx. 1U height, 19-inch width).
6. Ideal for a wide range of audio applications requiring multi-channel microphone feedback protection, such as KTV entertainment, stage choirs, conferences, live performances, and lecture halls.
