MATCH UP 4DSP 4 Channel Class GD Amplifier with 5 Channel DSP for OEM Upgrade
A compact plug-and-play 4-channel Class GD amplifier with an integrated 5-channel DSP purpose-built for upgrading factory OEM sound systems. Delivers 2 x 60W RMS at 4 Ohm on the main channels and 2 x 85W RMS at 4 Ohm (2 x 140W at 2 Ohm) on the subwoofer channels, with 4-channel ADEP.3 high-level input, ACO platform, optical SPDIF input, mono RCA output, and start-stop capability up to 18V for hybrid and EV compatibility. Full configuration via DSP PC-Tool 6.
Product Overview
The MATCH UP 4DSP is a compact 4-channel Class GD amplifier with an integrated 5-channel DSP, designed as an efficient upgrade for vehicles fitted with simple 2 or 4-channel factory radios. With optional plug-and-play cable harnesses and an intelligent 4-channel high-level input featuring ADEP.3, the UP 4DSP integrates cleanly into modern OEM architectures without the complexity of larger multi-channel systems.
The main channels (A-B) deliver 2 x 60W RMS at 4 Ohm for a front speaker system. The subwoofer channels (C-D) deliver 2 x 85W RMS at 4 Ohm or 2 x 140W RMS at 2 Ohm for compact bass upgrades. A mono RCA output at 3V enables connection of an external amplifier. An optical SPDIF input (12-96kHz) supports digital sources and aftermarket head units. The start-stop ready power supply operates up to 18V, ensuring full compatibility with modern hybrid and electric vehicle platforms.
The integrated DSP uses a 64-bit fixed-point audio processor at 295 MHz with dual BurrBrown A/D and D/A converters, supported by the 32-bit ACO CoProcessor with ISA (Input Signal Analyzer), TuneEQ, RealCenter, Augmented Bass Processing, Dynamic Loudness Control, and Remote Tone Control. Full configuration is via DSP PC-Tool 6. An SCP port enables connection of compatible MATCH and HELIX remote controls and accessories.
Features & Benefits
Purpose-Built for OEM Upgrade: The UP 4DSP is designed specifically for upgrading standard factory sound systems, with optional plug-and-play harnesses for OEM integration and an ADEP.3 high-level input that compensates for factory equalisation and processed OEM signals for a clean input signal.
Class GD Technology with Dynamic Power Supply: The proprietary Class GD amplifier technology dynamically controls the power supply for high efficiency and low heat dissipation, combining the audio quality advantages of Class A/B with the efficiency of Class D.
Dual Output Configuration - Front and Subwoofer Channels: Channels A-B deliver 2 x 60W RMS at 4 Ohm for the front speaker system. Channels C-D deliver 2 x 85W RMS at 4 Ohm or 2 x 140W RMS at 2 Ohm for subwoofer applications, providing a complete front and bass upgrade from a single compact unit.
Integrated 5-Channel DSP with 64-Bit Processing: A 64-bit fixed-point DSP at 295 MHz with BurrBrown A/D and D/A converters provides precise parametric EQ, time alignment, crossover filters, and virtual channel processing via DSP PC-Tool 6.
ACO Platform with ISA, TuneEQ, RealCenter and Augmented Bass Processing: The 32-bit ACO CoProcessor adds ISA (input signal analysis and InputEQ correction), TuneEQ (automated EQ correction via measurement microphone), RealCenter (dynamic centre channel synthesis), Augmented Bass Processing (Dynamic Bass Enhancement and SubXpander), Dynamic Loudness Control, and Remote Tone Control.
Start-Stop and EV Ready up to 18V: The extended operating voltage range up to 18V ensures full compatibility with modern hybrid and electric vehicle platforms, maintaining uninterrupted operation during start-stop events.
Mono RCA Output for External Subwoofer Amplifier: The 3V mono RCA output enables connection of an external amplifier, allowing the system to be expanded with a dedicated subwoofer amplifier when required.
Compact 46 x 130 x 110mm Form Factor: The small footprint enables installation in tight spaces such as under seats, behind panels, or in other space-restricted vehicle locations.

Frequently Asked Questions
Does the UP 4DSP accept RCA inputs from a head unit?
No. The UP 4DSP is a high-level input only amplifier. It accepts signal via 4 x high-level speaker inputs with ADEP.3, or via the optical SPDIF digital input. There are no RCA inputs. This makes it ideal for OEM factory radio upgrades where a head unit RCA output is not available.
What is ADEP.3 and why does it matter for OEM integration?
ADEP.3 is MATCH's smart high-level input circuit that compensates for factory equalisation, boosted output voltages, and other OEM sound processing. It analyses and corrects the input signal from the factory radio, delivering a clean, flat signal to the DSP for accurate sound tuning. This eliminates the tonal colouration introduced by factory audio processing in most OEM integration scenarios.
Is the UP 4DSP compatible with hybrid and electric vehicles?
Yes. The extended operating voltage range of up to 18V and start-stop capability (down to 6V for short periods) ensures full compatibility with hybrid and electric vehicle platforms where supply voltage may vary significantly compared to conventional 12V systems.
Can I connect an external subwoofer amplifier to the UP 4DSP?
Yes. The mono RCA output at 3V RMS allows an external amplifier to be connected to the UP 4DSP for subwoofer expansion or to drive additional channels beyond the built-in 4-channel output.
What optional harnesses are available for plug-and-play OEM integration?
The UP 4DSP supports optional vehicle-specific plug-and-play cable harnesses for direct connection into factory wiring without cutting or splicing. Please contact us with your vehicle make, model, and year to confirm available harness options for your specific installation.
