Professional Audio Signal Processor

Designed for precision audio control and professional sound reinforcement, this Professional Audio Signal Processor is the ultimate choice for audio engineers, sound technicians, and live performance venues. Built with advanced electronics and studio-grade components, it delivers clean, accurate sound across a wide frequency spectrum with minimal distortion.

Versatile Input Options for Flexible Integration

The system features two electronically balanced and RF-filtered line inputs, along with one dedicated RTA mic input, all using male XLR connectors. The input impedance exceeds 40k ohms, allowing seamless connectivity with various audio sources. It supports a maximum input level of +30dBu when jumpers are set to the +30 position, providing headroom for even the most demanding signals.

Powerful Outputs with Clarity and Control

Equipped with six electronically balanced, RF-filtered male XLR outputs, this processor allows flexible routing and connectivity. Each output has an impedance of 120 ohms and supports a maximum output level of +22dBu, delivering clean, high-powered audio to your amplifiers or mixing systems.

Superior Audio Quality and Performance

The unit boasts a dynamic range of over 110dB (A-weighted) and 107dB unweighted. This ensures rich detail and clarity across the full frequency spectrum. Its THD+Noise is as low as 0.003% (measured at +4dBu, 1kHz, 0dB gain). Even at high output levels, it maintains ultra-clean, professional-grade sound.

. The frequency response of 20Hz to 20kHz (+/- 0.5dB) ensures full-range audio that’s both accurate and natural.

Interchannel crosstalk is rated at over 110dB, with 120dB typical. The input-to-output crosstalk exceeds 100dB. These figures help minimize signal bleed and preserve the integrity of each channel.

Reliable Power and Build Quality

This processor operates on 230V AC at 50/60Hz, suitable for international professional audio setups. Built for portability and protection, it comes with packing dimensions of 90mm x 560mm x 290mm. The net weight is 2.5kg, and gross weight is 3.18kg, making it compact and easy to transport or rack-mount in mobile setups.

Whether you’re managing a live stage show, tuning a high-end PA system, or running sound in a worship space or studio, this professional signal processor delivers the control, precision, and sound quality that professionals demand.
