About the amplifier

General design
The Gato Audio DPA-4004 is a 4 channel fl exible power amplifi er that off ers unparalleled power and performance in the smallest and most
beautiful package. The DPA-4004 off ers no less than 4x400W / 8ohm, doubling in 4ohm. Each pair of channels is bridgeable – enabling this
fully confi gurable powerhouse to be used for either multichannel setups, active systems or for bi-amping speakers. This amplifi er is the
obvious choice for the Gato Audio PRD-3 preamplifi er/DAC, but is also very suitable as a workhorse for the integrated amplifi ers DIA-250
and DIA-400 – off ering even more channels and fl exibility. For multichannel systems it will serve as a slave for a surround processor perhaps
in combination with a PRD-3, DIA-250 or DIA-400 enabling their Home Theater setting.
Class-D Output Stage
The DPA-4004 amplifi er off ers four state of the art Class-D output stages with dedicated and optimized switch mode power supplies. The
multiple stage power amplifi ers are built around proven technology from International Rectifi er, optimized with a precision high frequency
oscillator and PWM modulator. A pair of 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 fi lters are made from quality PP capacitors and low DCR coils,
converting the high power PWM signals back into detailed and smooth analogue music.
