Overview

Our take on the Match PP82DSP

The Match PP82DSP signal processor will greatly improve the sound quality of your factory audio system without cutting wires or changing your vehicle's look. This compact box holds a wealth of sound processing tools, along with an 8-channel amplifier that can power a variety of systems. After the PP82DSP works its magic, you'll be able to hear music like you were in the front row of a concert, instead of outside in the parking lot.

Upgrade your vehicle's stock system for high-fidelity sound

The Match PP82DSP signal processor will greatly improve the sound quality of your factory audio system without cutting wires or changing your vehicle's look. This compact box holds a wealth of sound processing tools, along with an 8-channel amplifier that can power a variety of systems. After the PP82DSP works its magic, you'll be able to hear music like you were in the front row of a concert, instead of outside in the parking lot.

The vehicle-specific Match Plug and Play input/output harness system

First, you'll need to purchase a vehicle-specific adapter harness that plugs in between your car's stock radio and speakers, then connects to the PP82DSP. The PP82DSP then takes the signal from the factory radio and transforms it into focused, clear, and powerfully moving music.

Power features

The processor's built-in amplifier puts out 55 watts RMS to each of your car's front and rear speakers, along with up to 280 watts RMS to an optional Match PP10E-D subwoofer so you'll definitely feel your music's impact. For you subwoofer fans who want more bass than that, the PP82DSP also includes outputs for hooking up your own larger amplifier and sub.

You can also set up the PP82DSP to run an active speaker system, driving your tweeters, midbass drivers, and subwoofers with separate channels.

Warning: Because of its high power and digital connections, setting up and running this processor improperly could damage your speakers. Please read the instruction manual carefully before you connect your Match PP82DSP.

The ultimate tune-up via PC

Helix Match PP82DSP

The main control panel for the PP82DSP, as it appears on your computer screen

If you're a constant tweaker who's crazy about sound quality, then you will have a blast with the PP82DSP. It works with your Windows-operated personal computer to offer a world of sonic adjustments that can maximize the performance of almost any car audio system.

Once you've downloaded the application and software from Audiotec Fischer, you plug your PC or laptop into the processor's USB port. A detailed control panel will appear on your computer screen that lets you set virtually every tunable audio parameter, so you achieve the highest musical fidelity possible in your car. The visual display shows the resulting sound curve of each setting, so you'll know for sure how your adjustments are affecting audio output.

EQ, time alignment, and more

The PP82DSP processing includes a 30-band graphic equalizer on every channel, to compensate for all the dips and bumps in your speakers' responses inside your car, so each speaker will sound its best. The EQ section also features a fine tuning adjustment that lets you get in between the preset bands to smooth out any rough spots. The time alignment feature lets you correct for each speaker's placement, so the sound from each speaker gets to you at the same time, centering the stereo image for your sitting position.

Detailed filter section for fine tuning

You can configure almost any type of high-pass and low-pass filter on each channel. Not only can you adjust a crossover's frequency, but you can also choose the slope, its "filter characteristics" (see Highlights below), and adjust its "Q-factor," which widens or tightens the bump at a particular crossover point. Filters and EQ can be set separately for each channel, or channels can be linked together for common settings.

Save your settings

Don't worry, you won't have to drive around with your computer plugged in. You simply download your settings to the PP82DSP, after saving them on your laptop. The PP82DSP can store two settings at once, so you can toggle between them to see which sounds better. You can also use an optional microSD memory card to store and transfer settings to your PP82DSP, which comes in handy when you want to switch settings without plugging in your laptop.

Additional features

An auxiliary input lets you plug in other sources like an MP3 player or a navigation device. The PP82DSP senses when a signal is present there and automatically switches to AUX mode to play it. If it hears nothing for 2 seconds, it switches back to the receiver's signal.

You can use the URC-2A remote control (not included) to control several functions of your processor from the front seat, without having to plug in a computer. You can adjust the main and subwoofer volumes, switch between your receiver and auxiliary sources, and even quickly switch back and forth between two previously saved processor setups. You can re-configure some of the URC-2A's functions using the DSP-PC Software.

The PP82DSP also features an optical digital input so you can play music directly from a compatible device and maintain the highest sound quality possible. You'll need to get the URC-2A remote in order to activate this input and control your digital source's volume.

Power Save Mode

Many newer vehicles feature accessory circuits that remain on for several minutes after the engine shuts off, so an aftermarket amplifier could possibly drain your vehicle's battery. The Match PP82DSP solves this problem by turning off the amps connected to its remote output after not sensing music for 60 seconds. It will turn them back on within a second after sensing the signal.

Online manual

For more details and tips, check out Audiotec Fischer's DSP Special Sound Tuning Magazine, which includes the operation and adjustment manual for the Match PP82DSP.

Important Note: This Match upgrade system plugs in between your vehicle's factory radio and speakers, so it will not work in a premium sound system equipped with a factory amplifier. You must identify your vehicle to order a Match Plug and Play upgrade system online. Or, if you prefer, call an Advisor at 1-888-955-6000 to make sure you get the upgrade system that works in your vehicle.

Mode switches set amp gains and remote control functions.

Once I finally located the radio under the cargo panel by the right rear tail light the PP 82DSP hooked up very easy and I didn't have to reroute anything but, I did need to run a power cable to the unit from the battery and ground to the vehicle for this unit.

For the price nothing is better.

Bryce from Virginia Beach, VA on 1/30/2017

Amazing product. I'm an install shop manager in Virginia Beach and my clients love this unit. 55w X 8 is perfect for any SQL oriented setup, lots of flexibility using the tuning interface on PC. Wire harness that it comes with is neat and easy to run, but is a bit short (probably not going to reach to your trunk in a sedan) but is plenty long for installing the DSP/AMP under a front seat. For the price its almost impossible to beat. Check out the plug and play vehicle specific harness you can use with this unit if you would rather not cut/solder anything.

Pros: Insanely small, perfect for mounting in weird locations. Sound quality is amazing. Tuning interface is easy to use. Cheap!

Cons: They don't label which harness is your input or output side if you are hardwiring into the vehicle. You can figure it out if you've been installing for a while just based on how the T-Harness is set up, but a novice would have some trouble.

Crutchfield Customer Review (What's this?)

Once I finally located the radio under the cargo panel by the right rear tail light the PP 82DSP hooked up very easy and I didn't have to reroute anything but, I did need to run a power cable to the unit from the battery and ground to the vehicle for this unit.

Pros: Easy Plug and Play and sounds great with the dedicated sub woofer PP 10e-d and the stock speakers. The unit stays cool during operation. Very flexible foundation in which to build onto with more amps and speakers if one would desire. Crutchfield Replacement was very fast and easy for a DOA issue. No cutting into wiring.

Cons: The first Unit I received was DOA and deemed to be defective. That's why only 4 stars. Hey It happens!

Features

Overview: The Helix PP 82DSP is an amplifier and digital signal processor, designed to be used with a Helix vehicle specific adapter to create a plug & play upgrade to a factory stereo system. Once the PP 82DSP is installed, the vehicle specific profile containing customized EQ and time alignment data is downloaded from the Helix web site to a MicroSD card and loaded into the DSP (be sure to check their site before purchasing to confirm they have a profile for your car). This allows you to upgrade your vehicle's factory sound, while leaving all the factory features and controls intact. If no profile is available for your vehicle, extensive adjustments can be made to the EQ, crossover, and time alignment using Audiotec Fischer's DSP PC-Tool software, downloaded free from their web site.

Channel Layout: The PP 82DSP is an 8-channel amp with two distinct sets of outputs. The channels are labeled A through H, with A through D wired through the System Connector harness back to the factory speakers (Front Left, Front Right, Rear Left, and Rear Right). Each of these main channels has a full range, 30-band equalizer, both high pass and low pass crossovers, and time alignment adjustment. Channels E through H are on a separate harness, designed to power the optional Helix PP 10E-D or PP 8E-Q subwoofer. Each of these channels has a 12-band equalizer along with the high pass and low pass crossovers, and time alignment adjustment. Even though E through H are designed as subwoofer channels, the crossovers offer full range options, so they can be used to drive other speakers. Unfortunately no harness is included that plugs into the port (either sub includes the necessary cable).

Connections/Controls:

  • Left Side:
    • Output Channels E-H: 8-pin plug; output for amplifier channels E, F, G, and H; connects to optional PP 10E-D or PP 8E-Q subwoofer; these outputs can also be used to drive other speakers, but no harness is included that plugs into the port; power output is 55 watts x 4 RMS into 4Ω/70 watts x 4 RMS into 2Ω
    • Line Output: two RCA jacks for connection to another amp; can be formatted as full range stereo or subwoofer outputs
    • Optical Input: toslink port (stereo signal only); the URC 2A (item number 975URC2A, sold separately) is needed to engage the optical input; compatible with 6 kHz to 192 kHz sampling rates
    • Aux Input: 3.5mm mini-jack input; a signal sensing circuit automatically switches to the aux input when a signal is present
    • System Connector: 20-pin port for use with the included cable
  • Right Side:
    • Power: set screw terminals:
      • Power: compatible with up to 4-gauge wire, 8-gauge minimum recommended; 4mm Allen wrench required (not included)
      • Ground: compatible with up to 4-gauge wire, 8-gauge minimum recommended; 4mm Allen wrench required (not included)
      • Remote turn-on output: output for external amp; compatible with up to 10-gauge wire; 2mm Allen wrench required (not included)
    • Mode Switches: 6 DIP switches adjust multiple settings; amplifier gain, relative sub level, and optional wired remote function
    • Control Input: input for optional URC 2A wired remote control (item number 975URC2A, sold separately)
    • USB: connect to your computer using the included cable (not used for USB storage devices)
    • Micro SD: operating software updates and complete DSP settings files are downloaded using the MicroSD card slot

Computer Controls: These controls are on the Helix PC-Tool software, downloaded to your computer from their web site (If a vehicle specific profile is downloaded, its settings cannot be changed using the PC-Tool):

  • Crossover: The crossovers are set for each channel individually, or multiple channels can be linked together and adjusted simultaneously (left and right, front and rear, etc.). Each channel has high pass and low pass crossovers; either or both can be bypassed. There are four settings for each crossover:
    • Frequency: The crossover points for each channel vary by how the channel is defined:
      • Full Range (Channels A through D): high pass and low pass adjustable from 20 Hz to 20.480 kHz in approximately 1/12 octave increments
      • Subwoofer (Channels E through H): high pass (subsonic) adjustable from 20 to 100 Hz, low pass adjustable from 20 to 300 Hz, both in 1 Hz increments
    • Filter Characteristics: Different crossover types exhibit different sonic characteristics:
      • Butterworth: regular impulse behavior, sharp transition, 3 dB gain in the crossover frequency band, suitable for almost all applications
      • Bessel: very good impulse behavior, very gradual transition (drivers must have smooth frequency response outside the frequency band range), less than 1 dB gain in the crossover frequency band, only practical with very high quality speakers, not recommended for use with subwoofers
      • Linkwitz: very good impulse behavior, no gain at the crossover frequency, only practical with very high quality speakers, not recommended for use with subwoofers
      • Tschebyshev: very sharp transition, poor impulse behavior, output exhibits 1 dB ripple, only recommended for a subwoofer or tweeter operating near the resonant frequency
      • Self Defined: useful as high pass (subsonic) in ported subwoofer systems, slope fixed at 12 dB/octave, Q value adjustable from 0.5 to 2.0
    • Slope: the crossover slopes are selectable; zero (bypassed), 6 dB/octave, 12 dB/octave, 18 dB/octave, 24 dB/octave, and 30 dB/octave (Linkwitz is limited to zero, 12 dB/octave, and 24 dB/octave; Self Defined is fixed at 12 dB/octave)
    • Q Factor: using the Self Defined filter characteristic setting, the Q factor can be adjusted from 0.5 to 2.0 in 0.1 increments
  • Output Level: The output levels are independently adjustable for each of the eight output channels. The range is +5 dB to -60 dB (1 dB steps from +5 dB to -10 dB, 2 dB steps from -10 dB to -30 dB, and 6 dB steps from -30 dB to -60 dB).
  • Phase: The phase of each output channel is independently adjustable. The subwoofer channels (E through H) are adjustable from 0° to 360° in 22.5° steps; the full range outputs can be set to 0° or 180°.
  • Time Alignment: The distance from the listener (for one position in the car) to the speaker connected to each channel is independently adjustable from zero to 318cm (approximately 11 feet) in 7mm (0.28") increments.
  • Equalizer: Channels A through D have individual 30 band equalizers (25 Hz, 32 Hz, 40 Hz, 50 Hz, 63 Hz, 80 Hz, 100 Hz, 125 Hz, 160 Hz, 200 Hz, 250 Hz, 315 Hz, 400 Hz, 500 Hz, 630 Hz, 800 Hz, 1 kHz, 1.25 kHz, 1.6 kHz, 2 kHz, 2.5 kHz, 3.15 kHz, 4 kHz, 5 kHz, 6.3 kHz, 8 kHz, 10 kHz, 12.5 kHz, 16 kHz, and 20 kHz), channels E through H have individual 12 band equalizers (25 Hz, 32 Hz, 40 Hz, 50 Hz, 63 Hz, 80 Hz, 100 Hz, 125 Hz, 160 Hz, 200 Hz, 250 Hz, and 315 Hz). Each band is adjustable from -15 dB to +6 dB in 1 dB steps. A fine tuning section also allows slight adjustment of each band's center frequency (eight options in 1/12 octave steps) and Q (0.5 to 15.0 in 0.1 steps).
  • Line Output Configuration: The signal output by each of the line outputs mirrors the settings for channels G and H.
  • Input Configuration: The signal output by channels E through H can be supplied by any combination of the four inputs from the factory system (right/left/front/rear).

No. The DSP amp should have no effect whatsoever on the radio or Bluetooth functionality. I have had this unit for probably 18 months, and I absolutely love it. The sound tuning capabilities are amazing. [ Odic  Nov 28, 2016 ]
I have a bmw ,this amp was made to work with my car, so for my car there are no problems I dont know what car do u have and what settings u need Good luck [ FLORENTIN  Nov 28, 2016 ]
No, this is just an amp and has no effect on the head unit and/or bluetooth antenna module and antenna. It depends on your vehicle you have. You can google your year make and model of your car to find a forum, and then search within the forum how does my vehicle receive bluetooth commands. [ scoop  Nov 28, 2016 ]
I don't have a kicker subwoofer, but I see no reason that you couldn't drive it with this. I'm driving the dual-coil subwoofer from a OEM+ system using it, with 2 of the channels assigned (1 per coil). Hope that helps! [ Odic  Nov 24, 2015 ]
