Gato Audio DPA-2506
High End Class D 6-Channel / Bridgeable Power Amplifier
"...the Gato transforms my listening space into a concert hall and make the illusion perfect; you think you’re in the first row, you forget time and space."
MARKUS LEIBL, HI-FI STARS
The Gato Audio DPA-2506 is a 6 channel flexible power amplifier, that offers unparalleled power and performance in the smallest and most beautiful package.
The DPA-2506 offers no less than 6x250W into an 8ohm load, doubling into 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.
Class-D Output Stage
The DPA-2506 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.
Single Ended and Bridge Configuration
The DPA-2506 can be configured to 3, 4, 5 or 6 channel operation, accommodating your specific system requirements. The DPA-2506 offers in total four discrete output stages, organized in two sections each containing two channels.
All sections can be configured as single ended or as bridged outputs. Each section is configured by its own little switch on the back of the amplifier. Move the switch towards the corresponding symbol on the rear of the chassis if you want to set the section in two channel mode (single ended) or towards the other corresponding symbol if the section should be set to one channel mode (bridge).
This individual control of each section makes it possible configure the DPA-2506 exactly to your needs or system requirements. Note that when a section is configured as "bridge", the connections on the back of the amplifier are changed; the speaker will share connectors from both channels in this section. One uses the highlighted (+) terminal from one channel and the highlighted (-) terminal from the other channel. Note that one uses only one of highlighted inputs in this section, either the unbalanced marked "Ch 1", or the balanced connector marked as "Ch 1 BAL" .
The specific inputs and outputs for each section during bridge mode is shown in the below illustration :
