Match PP 86DSP MK2 – 8-Channel Plug & Play DSP Amplifier
The PP 86DSP MK2 is the multi-channel Plug & Play amplifier of the MATCH range from Audiotec Fischer. It offers eight amplifier channels, a 1-channel mono line output and a 9-channel DSP, and is designed to upgrade multi-channel factory sound systems. All amplifier channels are stable down to 2 Ohms, so nearly all OE speakers can be driven, and optional cable harnesses simplify integration into the vehicle.
Technically it is built around Class HD amplification, which dynamically varies the supply voltage to reduce idle losses, a 64-bit fixed-point audio DSP and the ACO 32-bit CoProcessor platform with ISA, Input EQ, TuneEQ and SFX effects. Virtual Channel Processing handles complex OEM routing, and the MEC slot allows expansions such as Bluetooth HD audio or USB high-resolution streaming. Setup is done with DSP PC-Tool 5.
Key Features
- 8 channels + mono line out + 9-channel DSP: Complete system amplifier for multi-way factory systems.
- 2 and 4 Ohm stable: On all amplifier channels, for compatibility with nearly all OE speakers.
- Class HD: Combines Class H and Class D principles for high efficiency and low heat in a compact housing.
- 64-bit DSP: Fixed-point audio signal processor, 295 MHz (1.2 billion MAC operations per second), 48 kHz.
- ACO 32-bit CoProcessor: ISA and Input EQ, TuneEQ, and SFX such as Augmented Bass Processing and RealCenter.
- Smart 6-channel high-level input: ADEP.3 circuit, sensitivity adjustable from 5 to 11 V.
- VCP: Virtual Channel Processing for highly complex systems.
- MEC slot: For expansions such as Bluetooth HD audio streaming and USB high-resolution streaming; with the optional MEC ANALOG IN module, 1:1 Input-to-Output Routing (IOR) is possible.
- Optical SPDIF input: 12–96 kHz, with automatic digital signal detection.
- Mono line output: For an external amplifier such as the MATCH UP 1FX subwoofer amplifier; galvanically isolated.
- Smart Control Port: For accessories such as DIRECTOR and CONDUCTOR.
- Start-Stop capable supply: Input voltage range up to 18 V, suited to modern EVs; Auto Remote switch.
Inputs & Outputs
- Inputs: 6 x high-level speaker input, 1 x optical SPDIF (12–96 kHz), 1 x MEC, 1 x remote in.
- High-level input: Sensitivity 5–11 V; input impedance 9–33 Ohms with ADEP.3.
- Outputs: 8 x speaker output, 2 x RCA (mono) with 3 V RMS, 2 x remote out (max. 500 mA).
- Automatic Digital Signal Detection: Switches to the optical input when a signal is present; can be disabled in the DSP PC-Tool.
Power & Amplifier Section
- Output power RMS: 8 x 55 W @ 4 Ohms, 8 x 70 W @ 2 Ohms.
- Frequency response: 20 Hz – 22,000 Hz.
- Signal-to-noise ratio: 105 dB digital input, 103 dB analog input (A-weighted).
- Distortion (THD): < 0.015 %; damping factor > 100.
- Idle current: 685 mA.
DSP & Sound Tuning
- Converters: BurrBrown A/D and D/A.
- TuneEQ: One measurement per channel or channel pair with a measurement microphone such as the MTK1 automatically sets centre frequency, Q and gain of the parametric EQ to a reference curve.
- RealCenter: Builds a centre signal only from content common to both front channels; a signal in just one channel produces no centre output.
- Augmented Bass Processing: Dynamic Bass Enhancement boosts the low end and shifts the subsonic cutoff according to the input signal; SubXpander adds subharmonics between 50 and 100 Hz for a darker bass.
- Software: DSP PC-Tool 5 via USB.
Installation & Connectivity Notes
- Operating voltage: 10.5–18 V, max. 5 s down to 6 V; below 10.5 V for more than five seconds the unit enters protect mode (red LED).
- Power Save Mode: Enabled by default – the remote output switches off after 60 s without signal; timeout adjustable or mode can be disabled in the DSP PC-Tool.
- Fuse and power rating: 2 x 25 A LP-Mini fuse (APS); DC 12 V, 40 A max.
- Operating temperature: -40 °C to +70 °C.
- Dimensions (H x W x D): 44 x 185 x 164 mm.
- Harnesses: Optional MATCH cable harnesses (e.g. PP-VAG 2.6 Porsche Edition, PP-MQS 2.4 Basic shown as accessories) for factory system integration.
