VT204M is an advanced digital audio processor, using 24-bit / 48kHz delta-sigma A/D and D/A converters, with 128 times oversampling. Digital processing includes gain, reverse, parametric equalizer, filter, delay, split, compression, limiting and signal routing functions, all of which are completed by two high-performance DSP processors. All inputs and outputs use balanced outputs, while using XLR connectors.
This manual provides an overview of the VT204M digital audio processor, describing its 24‑bit/48 kHz delta‑sigma A/D and D/A converters, 128‑DSP architecture, and the LCD front‑panel with back‑lit LEDs for volume and mute indication. It details how to navigate the direct‑select menu, adjust gain, EQ, delay, crossover, limiter and routing for two inputs and multiple outputs.
The document also covers power requirements, accessory list, connection diagrams, fault‑diagnosis procedures, and a full technical specification table, helping users set up, operate, and maintain the processor safely. This manual is written in Chinese.
