The four-channel Gato Audio DPA-4004 is a flexible solution that offers a variety of options and combinations with the number of power output channels. A feature of the amplifier is to use modern technology to build the Class-D output stages , which in combination with a bridge connecting channel enables the production of high output power with a compact and elegant design.

Real power

The Gato Audio DPA-4004 provides at least 4x400W under 8 Ohm load, and at 4 ohms the value of channel capacity doubles. Each pair of channels in the amplifier can be connected in a bridge circuit, allowing individually configured power for multi-channel systems, or bi-amping speakers. The most obvious candidate to work in conjunction with the DPA-4004 is the award winning Gato Audio PRD-3 pre amp/dac, but the new model can also accompany the DIA-250/400 integrated amplifier, offering more channels and flexibility in terms of channel capacity. In multichannel systems, the DPA-4004 can serve to enhance the surround sound processor signals, possibly in combination with PRD-DIA-250/400 in the "Home Theater" mode.

Class-D with true 'analogue' audio

The DPA-4004 is a technically advanced solution in the form of Class D output stages with a separate power supply. The amplifying part is built on proven technology, with an optimized precision high-frequency generator and PWM modulator. Fast and accurate switching MOS-FET transistors have a very low on-state resistance, providing superior performance at high frequency with a minimal loss. Output filters on quality polypropylene capacitors and coils with low resistance convert powerful PWM signals back into analogue for an immersive detailed and textured sound.
