{"product_id":"gatoaudiodpa4004bl","title":"Gato Audio DPA-4004 Multi-Channel Power Amplifier, Gloss Black","description":"\u003cp\u003eThe Gato Audio DPA-4004 is a four-channel Class-D power amplifier whose channels can be used individually or bridged in pairs into more powerful channels.\u003c\/p\u003e\u003cp\u003eIt's built in Copenhagen, and it shows: non-magnetic chassis, gloss finish, four full-fledged amplifiers with their own switch-mode power supplies. Every input is available balanced as XLR and unbalanced as RCA, the speakers connect via four pairs of gold-plated terminals, and a 12-volt trigger wakes the unit together with the system. This version comes in deep gloss black.\u003c\/p\u003e\u003ch2\u003eWhy the Gato Audio DPA-4004?\u003c\/h2\u003e\u003cp\u003eBecause it packs four amplifiers into one chassis and leaves it to you how the power is distributed: four channels for two zones, two bridged channels for thirsty speakers, or a mix of both. It shares its chassis and weight with the six-channel DPA-2506 – it redistributes the same footprint over fewer, but stronger channels.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cp\u003ePower that can be redistributed. In four-channel operation, 400 watts into 8 ohms are available per channel; bridged, that's 2× 800 watts, or mixed, 1× 800 watts plus 2× 400 watts – into 4 ohms, double that in each case. Add a frequency response spanning 2 hertz to 70 kilohertz, over 110 decibels of signal-to-noise ratio, and total harmonic distortion below 0.01 percent. Figures at which the amplifier stays in the background, where it belongs.\u003c\/p\u003e\u003ch3\u003eWho is the DPA-4004 suited for – and who is it not?\u003c\/h3\u003e\u003cp\u003eFor multiroom installations, home cinemas and bi-amping setups that want four powerful channels from a single unit. Plainly put: for a simple stereo system that's too much amplifier – that's what the AMP-150 or the PWR-222 monos are for. And anyone needing to feed more than four channels should reach for the DPA-2506.\u003c\/p\u003e\u003ch3\u003eHow does the DPA-4004 differ from the DPA-2506?\u003c\/h3\u003e\u003cp\u003eIn the number of channels and the power per channel: four channels at 400 watts into 8 ohms for the DPA-4004, six channels at 250 watts for the DPA-2506. How many zones and speakers you want to feed decides the question – not the model name.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eA flexible four-channel amplifier that adapts to the system rather than the other way around: powerful, cleanly built, unobtrusive in operation. At HD Zürisee in Wädenswil we plan with you how the four channels get distributed across rooms and speakers – and tell you honestly when a smaller solution is enough.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e four-channel amplifier, Class D, freely configurable (4, 3 or 2 channels)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower at 8 Ω:\u003c\/strong\u003e 4× 400 W · 2× 800 W (bridged) · 1× 800 W + 2× 400 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower at 4 Ω:\u003c\/strong\u003e 4× 800 W · 2× 1600 W (bridged) · 1× 1600 W + 2× 800 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended speaker impedance:\u003c\/strong\u003e 4–16 Ω individually, 8–16 Ω bridged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 20 Hz – 20 kHz (−0.5 dB), 2 Hz – 70 kHz (−3 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal harmonic distortion (THD):\u003c\/strong\u003e \u0026lt; 0.01 % at rated power\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e \u0026gt; 110 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 26 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 20 kΩ (RCA) · 40 kΩ (XLR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 2 pairs XLR balanced (Neutrik, gold-plated) · 2 pairs RCA unbalanced (gold-plated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker connections:\u003c\/strong\u003e 4 pairs gold-plated safety banana terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrigger:\u003c\/strong\u003e 12V standby trigger (mini-jack)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply:\u003c\/strong\u003e 115\/230 V AC, 50\/60 Hz, max. 2000 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e \u0026lt; 1 W standby · 75 W idle · 2000 W maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis:\u003c\/strong\u003e non-magnetic, gloss black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W×H×D):\u003c\/strong\u003e 32.5 × 10.5 × 42 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 13 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Gato Audio, Copenhagen (Denmark)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScope of delivery:\u003c\/strong\u003e power amplifier, power cable, mini-jack cable for the trigger, manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eHow many speakers does the Gato Audio DPA-4004 drive?\u003c\/h3\u003e\u003cp\u003eIn four-channel operation, four individual channels, so two stereo pairs across two zones. Two channels can be bridged into a more powerful one: that gives 2× 800 watts into 8 ohms, and a mixed 1× 800 watts plus 2× 400 watts is also possible. You trade channel count for power, exactly as your system needs it.\u003c\/p\u003e\u003ch3\u003eDo I need a separate preamp for the DPA-4004?\u003c\/h3\u003e\u003cp\u003eYes. The DPA-4004 is a pure power amplifier with no volume control and no source selection, and therefore needs a preamplifier or an AV preamp ahead of it. The Gato PRD-3S is a match both sonically and visually, as is any preamp or multiroom system with balanced or unbalanced preamp outputs.\u003c\/p\u003e\u003ch3\u003eWhat's the difference between the DPA-4004 and the DPA-2506?\u003c\/h3\u003e\u003cp\u003eThe number of channels and the power per channel. The DPA-4004 delivers four channels at 400 watts into 8 ohms each, the DPA-2506 six channels at 250 watts each. Chassis, dimensions and weight are the same for both, so the decision comes down to the number of zones.\u003c\/p\u003e\u003ch3\u003eIs the DPA-4004 suitable for bi-amping?\u003c\/h3\u003e\u003cp\u003eYes. Each of the four channels can be addressed individually and connected either balanced or unbalanced, so the DPA-4004 drives one speaker pair with two channels each in bi-amping. This requires speakers with separate connection terminals – we check that together on your model beforehand.\u003c\/p\u003e\u003ch3\u003eWhy buy the Gato Audio DPA-4004 at HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause a multi-channel amplifier needs planning, and we provide it.
