The DPA-4004 offers no less than 4x400W in 8ohm load, doubling in 4ohm. Each pair of channels are bridgeable – enabling this fully configurable powerhouse to be used for either multichannel setups, active systems or for bi-amping speakers.
This amplifier is the obvious choice for the Gato Audio PRD-3s preamplifier/DAC, but is also very suitable as a workhorse for the integrated amplifiers DIA-250S and DIA-400S – offering even more channels and flexibility.
For multichannel systems it will serve as a slave for a surround processor perhaps in combination with a PRD-3S, DIA-250S or DIA-400S enabling their Home Theater setting.
The DPA-4004 amplifier offers two state of the art Class-D output stages each with dedicated and optimized switch mode power supplies. The multiple stage power amplifiers are built around proven technology from International Rectifier, optimized with precision high frequency oscillators and PWM modulators. Precision switching MOS-FET transistors, with super low on-resistance ensures the high frequency switching is done perfectly and with as little loss as possible. The output filters are made from quality PP capacitors and low DCR coils, converting the high power PWM signals back into detailed and smooth analogue music.
