Match UP 10DSP – 24V Edition – 10-channel Class GD upgrade amplifier with 11-channel DSP for 24 V vehicles

The MATCH UP 10DSP – 24V Edition (order no. M111005) is the 24-volt version of the 10-channel UP 10DSP from the MATCH UPGRADE amplifier range. It combines a 10-channel Class GD amplifier with an integrated 11-channel 64-bit DSP and is intended above all for upgrading multi-channel factory sound systems in trucks and buses, where the original equipment is often hard to replace. It is compatible with 24 V vehicle electrical systems only.

Its eight ADEP.3 high-level inputs (two of them accept up to 32 V) connect directly to the factory speaker lines, while an optical SPDIF input and a MATCH Extension Card (MEC) slot add further sources. Audiotec Fischer’s Class GD concept, the 32-bit ACO coprocessor and DSP functions such as TuneEQ, RealCenter and Augmented Bass Processing are packed into a compact 46 × 145 × 163 mm housing.

Key Features

10 amplifier channels, 11 DSP channels: 8 × 65 W RMS at 4 Ω on channels A–H plus two subwoofer channels (I–J) rated 2 × 90 W at 4 Ω or 2 × 160 W at 2 Ω, and one mono line output.
24 V only: operating voltage 18–36 V, designed for the electrical systems of trucks and buses.
8 high-level inputs with ADEP.3: two of the inputs (G–H) accept signals up to 32 V; ADEP.3 is designed to avoid diagnostic faults and lost functions such as the fader on factory radios.
Class GD amplifier: the internal supply voltage is varied in steps according to the input signal, reducing idle losses and heat so that small heat sinks are sufficient.
ACO 32-bit coprocessor: handles monitoring, communication and setup switching, has a boot loader for firmware updates and stores ten sound setups instead of the usual two.
Optical SPDIF input: accepts digital signals from 12 to 96 kHz, with automatic switching when a digital signal is detected.
MEC slot: MATCH Extension Card slot for modules such as Bluetooth audio streaming or USB high-resolution audio.
1:1 input-to-output routing: possible with the optional MEC ANALOG IN module.
Virtual Channel Processing (VCP): multi-stage routing for complex configurations in the DSP PC-Tool.
Smart Control Port (SCP): for accessories such as DIRECTOR and CONDUCTOR.
Start-stop capability: the internal supply stays stable when the battery voltage drops to 12 V during engine cranking.
Auto remote switch: and a galvanically isolated line output.

Inputs & Outputs

Inputs: 8 × high-level speaker input, 1 × optical SPDIF (12–96 kHz), 1 × remote in.
High-level input sensitivity: channels A–F 4–16 V; channels G–H selectable 4–16 V or 8–32 V. High-level input impedance 9–33 Ω with ADEP.3.
Outputs: 10 × speaker output, 1 × RCA (mono, e.g. for an external subwoofer amplifier), 1 × remote out.
RCA output voltage 3 V; maximum remote output current 500 mA.

Power & Amplifier Section

Channels A–H: 8 × 65 W RMS at 4 Ω.
Channels I–J (subwoofer): 2 × 90 W RMS at 4 Ω, 2 × 160 W RMS at 2 Ω.
Class GD amplifier technology with dynamically controlled power supply.
Frequency response 10 Hz – 22 kHz; THD below 0.03 %; damping factor above 100.
Signal-to-noise ratio: 105 dB (A-weighted) digital input, 103 dB (A-weighted) analogue input.
Operating voltage 18–36 V (for max. 5 s down to 12 V); power rating DC 24 V, 32 A max.; idle current 210 mA.
Fusing: 2 × 25 A LP-Mini (APS). Operating temperature −40 °C to +70 °C.

DSP & Sound Tuning

The 11-channel audio signal processor works with 64-bit resolution, 295 MHz (1.2 billion MAC operations per second) and a 48 kHz sampling rate, using BurrBrown A/D and D/A converters. Configuration is done via USB with the DSP PC-Tool.

TuneEQ: automated frequency response correction – a single measurement per channel or channel pair with a measurement microphone (the page names the MTK1) is enough for the software to set the parametric EQ bands (centre frequency, Q and gain) towards a target curve.
RealCenter: derives a centre signal only from the content common to the front left and right channels; its level follows the stereo content, so material present on only one side produces no centre output.
Augmented Bass Processing: combines Dynamic Bass Enhancement (input-dependent low-frequency boost and subsonic filter adjustment) with SubXpander, which adds subharmonics between 50 and 100 Hz for a deeper bass.
Input EQ with Input Signal Analyzer: run on the ACO coprocessor to analyse and correct the factory signal.
VCP and IOR: virtual channel processing for complex set-ups; 1:1 input-to-output routing with the optional MEC ANALOG IN.

Installation & Connectivity Notes

Suitable for 24 V vehicle electrical systems only.
Compact dimensions of 46 × 145 × 163 mm (H × W × D) allow installation in confined spaces.
If the supply voltage stays below 21 V for more than five seconds, the amplifier switches to protect mode, indicated by a red status LED.
Power Save Mode is active by default: after 60 seconds without input signal the remote output (and connected amplifiers) switch off and reactivate within about one second when a signal returns; the timeout can be changed or disabled in the DSP PC-Tool. The page notes that some CAN-bus vehicles keep the radio invisibly on for up to 45 minutes after locking.
Automatic digital signal detection can be disabled in the DSP PC-Tool, or the input can be switched manually with an optional remote.
