Features

Overview: The Match PP 86DSP is an 8 channel amplifier with Audiotec-Fischers latest generation of 64 bit DSP sound processing, proprietary Class HD technology, and "Plug & Play" ease of installation. Sound configuration is straightforward and intuitive using the DSP PC-Tool V4 software, which offers full input and output routing for all channels, 30 bands of EQ, high and low pass filtering, time alignment, and more. The amp has 8 integrated channels at 55 watts each, an additional configurable set of speaker outputs, and 2 mono RCA outputs. The PP 86DSP includes an 8-channel interface harness that, when used with an optional vehicle-specific "T" harness (sold separately), allows the amp to be directly plugged into the vehicle's wiring while retaining the factory radio, making installation much easier.

Class HD Technology: The PP 86DSP combines the advantages of Class H technology with the principle of a Class D amplifier. The result is an unsurpassed efficiency which easily outperforms any conventional Class D amp. By varying the internal supply voltage depending on the amplifier's amplitude of the input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time.

Internal DSP: The PP 86DSP can be connected to your PC via USB with the supplied 59" USB cable. The DSP PC-Tool software can be downloaded to your PC from the Audiotec-Fischer website, and is compatible with Windows XP, Vista, 7, and 8. The "fixed point" Audio DSP features 64-bit resolution and 1.2 billion MAC operations per second, and includes a Real-time Analyzer (RTA), digital time alignment, phase adjustment, high-pass and low-pass filters, 30-band parametric EQ, and output level adjustment.

Match Extension Card slot (MEC): Match has included an Extension Card slot inside the amplifier to accommodate one of their optional Extension Cards (sold separately), which will add a specific feature such as Bluetooth connectivity, High Resolution Audio streaming via USB, etc. Each of the cards comes with a replacement side panel for the amp, which provides the necessary cut-outs for the additional ports. To access the Extension Card slot the end and bottom panels are removed by taking out three Philips-head screws from the end plate and sliding out the bottom panel.

Advanced Diagnostics Error Protection (ADEP): The amplifier utilizes a new ADEP circuit to allow it to be integrated with new OEM car stereos. Newer stereos can detect the presence of connected speakers, and when common amplifiers are connected, the radio will display failure messages with some features, such as fader function, being lost. The ADEP circuit avoids these problems without loading the speaker outputs of the factory stereo during high volumes.

Automatic Signal Detection: Switching from analog to the digital input is done automatically as soon as a digital signal is detected on the Optical input. This feature can be deactivated in the DSP PC-Tool software and can be switched manually with an optional remote control.

Power Save Mode: The Power Save Mode will automatically turn off the amplifier if no input signal is present for more than 60 seconds. In many newer cars with CAN-bus or other bus systems, the factory radio can remain powered on for up to 45 minutes after the ignition is turned off. When the amp receives this signal, the internal amplifier stages and the remote output are immediately powered on again. The Power Save mode can also be modified or deactivated via the DSP PC-Tool software.

Start-Stop Capability: The switched power supply of the Match PP 86DSP assures a constant internal supply voltage even if the battery's voltage drops to 6 volts during engine cranking. If the supply voltage drops below 10.5 volts for more than five seconds the amplifier will go into Protect mode (Status LED will light red) in order to avoid any more discharge of the battery.

Auto Turn-On: The PP 86DSP has the ability to use a high-level input signal to power on the amp when using either the System Connector or the High Level Input connector, and includes an Auto Remote switch on the amplifier. If turned off, or if using the Optical Digital input, a remote wire must be tied into the vehicle. The amp also includes a Remote Out terminal to activate other outboard equipment.

Connections:

• System Connector: The PP 86DSP was primarily designed to interface a factory system using the supplied System Connector in conjunction with a vehicle-specific "T" harness that ties right into the wiring at the back of the factory radio. The System Connector has a 20-pin plug harness on one end, that snaps into a socket on the amplifier, while the other end has 2 sets of male/female, input/output, ISO connectors that either plug directly into the factory wiring (on select European vehicles) or into one of the optional "T" harnesses.
• High-Level Inputs: A 4-pin High Level harness is included to tie directly into 2 speaker channels without using a "T" harness.
• Optical Input: An optical digital input is provided for connecting the amp to a digital source. The signal must be 2-channel PCM, no Dolby-coded signals will be recognized, with a sampling rate between 12 and 96 kHz.
• Speaker Outputs: An 8-pin Speaker Output harness is provided for hookup of additional speakers or subwoofers and are configurable.
• Mono Line Outputs: Two mono RCA jacks are provided to run to an outboard subwoofer amp.
• Power/Ground/Remote: The amp's power and ground inputs can accommodate up to 8 AWG wire (recommended) while the remote terminal can accept up to 16 AWG. Wires are held in place with hex-head set-screws, 4mm for the Power and Ground, 2mm for the Remote terminal.
• Control Input: A proprietary jack is provided for use with an optional remote control such as the Helix Director (sold separately).
• USB: The mini type-B USB port is used for running the PC-Tool software and firmware updates.
