{"product_id":"match-up-4dsp-4-channel-class-gd-amplifier-with-64-bit-dsp","title":"MATCH UP 4DSP 4-Channel Class GD Amplifier with 64 Bit DSP","description":"This compact 4-channel amplifier packs a 5-channel 64-bit DSP for precise sound tuning, making it ideal for upgrading factory audio systems without the bulk of larger multi-channel units. The two main channels deliver 2 x 60 Watts RMS at 4 Ohms for driving front speakers, while two additional channels provide 2 x 85 Watts RMS at 4 Ohms for subwoofer support. An optical SPDIF input and mono RCA output allow seamless integration with digital sources and external amplifiers. The start-stop-ready power supply works across a wide voltage range, ensuring compatibility with modern vehicles including hybrids and EVs. With the ACO platform, features like Augmented Bass Processing and RealCenter create a richer, more immersive soundstage.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAmplifier Technology\u003c\/strong\u003e: Class GD\u003cbr\u003e\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e: 4\u003cbr\u003e\u003cstrong\u003eOutput Power RMS (Channels A-B @ 4 Ohms)\u003c\/strong\u003e: 2 x 60 Watts (min. 3 Ohms)\u003cbr\u003e\u003cstrong\u003eOutput Power RMS (Channels C-D @ 4 Ohms)\u003c\/strong\u003e: 2 x 85 Watts\u003cbr\u003e\u003cstrong\u003eOutput Power RMS (Channels C-D @ 2 Ohms)\u003c\/strong\u003e: 2 x 140 Watts\u003cbr\u003e\u003cstrong\u003eDSP Resolution\u003c\/strong\u003e: 64 Bit\u003cbr\u003e\u003cstrong\u003eDSP Power\u003c\/strong\u003e: 295 MHz (1.2 billion MAC operations\/second)\u003cbr\u003e\u003cstrong\u003eSampling Rate\u003c\/strong\u003e: 48 kHz\u003cbr\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e: 15 Hz - 22,000 Hz\u003cbr\u003e\u003cstrong\u003eSignal-to-Noise Ratio (Digital Input)\u003c\/strong\u003e: 102 dB (A-weighted)\u003cbr\u003e\u003cstrong\u003eSignal-to-Noise Ratio (Analog Input)\u003c\/strong\u003e: 101 dB (A-weighted)\u003cbr\u003e\u003cstrong\u003eTotal Harmonic Distortion (THD @ 1 kHz, 1 W into 4 Ohms)\u003c\/strong\u003e: \u0026lt; 0.03%\u003cbr\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e: 4 x Highlevel speaker input, 1 x Optical SPDIF (12 - 96 kHz)\u003cbr\u003e\u003cstrong\u003eInput Sensitivity\u003c\/strong\u003e: 2.8 - 11 Volts\u003cbr\u003e\u003cstrong\u003eOutputs\u003c\/strong\u003e: 4 x Speaker output, 1 x RCA \/ Cinch, 1 x Remote Out\u003cbr\u003e\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 10.5 - 18 Volts (max. 5 sec. down to 6 Volts)\u003cbr\u003e\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -40°C to +70°C\u003cbr\u003e\u003cstrong\u003eDimensions (H x W x D)\u003c\/strong\u003e: 46 x 130 x 110 mm\u003cbr\u003e","brand":"MATCH","offers":[{"title":"Default Title","offer_id":53772644057425,"sku":"M114000","price":399.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/MATCH-UP-4DSP-perspective-29-09-25.jpg?v=1778707065","url":"https:\/\/shoponyxac.co.uk\/products\/match-up-4dsp-4-channel-class-gd-amplifier-with-64-bit-dsp","provider":"Onyx Auto Care","version":"1.0","type":"link"}
