Product Overview

The Match UP 8DSP is the flagship compact plug-and-play amplifier from the Match UPGRADE range, engineered as the definitive solution for seamless OEM system integration. The UP 8DSP delivers unbridled power and dynamics from an ultra-compact 46 x 130 x 153mm housing using the proprietary Class GD (Pure GD Ultra HD) technology, which dynamically controls the internal supply voltage to achieve extraordinary efficiency with very low heat dissipation. Channels A-F deliver 6 x 65W RMS at 4Ω for full-range speakers, while channels G-H deliver 2 x 90W RMS at 4Ω and 2 x 160W RMS at 2Ω for subwoofer applications.

The 6 high-level inputs with ADEP.3 Gen 3 circuitry (2.8-11V sensitivity) provide seamless connection to factory OEM head units and multi-channel factory sound systems. Optional cable harnesses (sold separately) further simplify integration into specific factory audio configurations. The optical SPDIF input accepts 12-96kHz signals. The MEC (MATCH Extension Card) slot accepts optional expansion cards including Bluetooth HD audio streaming and high-resolution USB audio streaming. The galvanically isolated mono RCA output provides 3V for connecting an external subwoofer amplifier.

The integrated 9-channel DSP runs on a 64-bit fixed-point audio signal processor at 295 MHz (1.2 billion MAC operations per second) with BurrBrown A/D and D/A converters, 48kHz sampling rate, SNR of 106dB from digital input and 104dB from analog input, and THD below 0.03%. The ACO 32-bit CoProcessor platform manages ISA (Input Signal Analyzer) with InputEQ for OEM signal correction, TuneEQ automated EQ calibration, VCP (Virtual Channel Processing) with cross-channel group equalizers, RealCenter, Augmented Bass Processing, Dynamic Loudness Control, and Remote Tone Control. Operating voltage is 10.5-17V with Start-Stop capability stable to 6V. Fused at 2 x 25A LP-Mini (APS).

Features & Benefits

Class GD Technology - Pure GD Ultra HD - Outstanding Efficiency with Low Heat Dissipation: Class GD dynamically controls the internal supply voltage in response to the amplifier's input signal, combining the efficiency benefits of a dynamically modulated supply rail with high-performance output stage design. The result is an amplifier with extraordinary efficiency, very low heat dissipation, and excellent audio performance in a compact form factor.

8-Channel Output - 6 x 65W RMS at 4Ω Plus 2 x 160W RMS Subwoofer Channels at 2Ω: Channels A-F deliver 6 x 65W RMS at 4Ω for full-range speaker channels, while channels G-H deliver 2 x 90W RMS at 4Ω and 2 x 160W RMS at 2Ω for powering large subwoofers, covering complete multi-channel speaker systems from a single amplifier unit.

9-Channel Integrated DSP - 64-Bit Fixed-Point at 295 MHz: The 9-channel DSP processes all output channels at 64-bit fixed-point resolution with 295 MHz clock speed (1.2 billion MAC operations per second), providing the processing power for complex multi-channel equalisation, crossover, time alignment, and sound effect processing simultaneously.

6 High-Level ADEP.3 Inputs for Seamless OEM Integration: The 6 high-level inputs with ADEP.3 Gen 3 circuitry (2.8-11V sensitivity, 9-33Ω input impedance with ADEP.3) are controlled by the ACO platform to interface correctly with the most advanced OEM head unit speaker load detection systems, enabling plug-and-play connection to factory audio systems without triggering error messages or loss of factory features.

Optional OEM Cable Harnesses for Specific Vehicle Fitments: Optional vehicle-specific cable harnesses (sold separately) provide pre-terminated plug-and-play connections into specific factory multi-channel sound system configurations, eliminating the need for custom wiring.

1:1 IOR with Optional MEC ANA-LOG IN Module: With the optional MEC ANA-LOG IN expansion card, the UP 8DSP provides 1:1 Input-to-Output Routing with the same number of high-level inputs and amplifier outputs, enabling direct signal routing from each factory speaker channel to its corresponding amplifier output channel.

ACO 32-Bit CoProcessor - ISA, TuneEQ, VCP, and SFX: The ACO platform handles ISA (Input Signal Analyzer) with InputEQ for analysis and correction of factory-processed input signals, TuneEQ automated parametric EQ calibration via measurement microphone, VCP cross-channel group equalizers and multi-way speaker configuration, RealCenter dynamic center image synthesis, and Augmented Bass Processing (Dynamic Bass Enhancement and SubXpander subharmonic bass extension).

MEC Slot - Modular Expandability: The MATCH Extension Card (MEC) slot accepts optional expansion modules including Bluetooth HD audio streaming and high-resolution USB audio streaming cards, allowing the UP 8DSP to be tailored to individual system requirements.

Galvanically Isolated Mono RCA Output: The galvanically isolated mono RCA output provides 3V for connecting an external subwoofer amplifier, with galvanic isolation preventing ground loop noise from the external amplifier connection.

Auto Remote Switch and Start-Stop Capability: The Auto Remote function activates the amplifier from the audio signal without requiring an external remote wire. Start-Stop capability maintains stable operation during voltage drops to 6V for up to 5 seconds.

VCP - Virtual Channel Processing: VCP enables cross-channel group equalizers affecting multiple output channels simultaneously and multi-way speaker configuration of DSP Sound Effects, providing maximum flexibility for highly complex sound system configurations.

SCP Smart Control Port: The SCP (Smart Control Port) connects optional accessories including the Match DIRECTOR and CONDUCTOR remote control interfaces.

Ultra-Compact Design - 46 x 130 x 153mm: The compact form factor suits installation in tight locations including under seats, factory amplifier positions, and OEM mounting areas typical of modern vehicle audio system upgrades.

Frequently Asked Questions

What is Class GD technology?

Class GD (Pure GD Ultra HD) is Match's proprietary amplifier technology that dynamically controls the internal power supply voltage in response to the amplifier's input signal amplitude. By continuously modulating the supply rail to match the signal level, idle losses are dramatically reduced and overall efficiency is maximised across all operating conditions, resulting in very low heat dissipation from a compact amplifier unit.

Does the UP 8DSP have RCA inputs?

No. The UP 8DSP uses high-level inputs only for signal input, with no RCA line-level inputs. Signal is accepted via the 6 high-level ADEP.3 inputs, optical SPDIF input, or MEC expansion card. A mono RCA output is provided for connecting an external subwoofer amplifier.

What is ADEP.3 and why does it matter for OEM integration?

ADEP.3 (Generation 3) is the smart high-level input circuit controlled by the ACO platform that correctly simulates the speaker load impedance expected by factory OEM head units with speaker load detection systems. This prevents error messages and loss of factory features when the UP 8DSP is connected to the factory speaker outputs of modern vehicles.

What optional accessories work with the UP 8DSP MEC slot?

The MEC (MATCH Extension Card) slot accepts optional expansion modules including Bluetooth HD audio streaming and high-resolution USB audio streaming cards, as well as the MEC ANA-LOG IN module for 1:1 Input-to-Output Routing. MEC accessories are sold separately.

How does the UP 8DSP differ from the Helix V Eight DSP Ultimate?

Both are 8-channel DSP amplifiers from Audiotec Fischer (the parent company of both Match and Helix) sharing the same ACO platform, 64-bit DSP, and ADEP.3 technology. The UP 8DSP (Match) is optimised for compact plug-and-play OEM integration with high-level inputs only, Class GD technology, and a 9-channel DSP at a smaller form factor. The V Eight DSP Ultimate (Helix) is the flagship performance unit with Class HD technology, 14-channel DSP, 12 high-level inputs plus 6 RCA inputs, USB PerfectStream, and higher maximum output power.
