About the Match DSP

Buck Pomerantz

Upgrade your stock system for high-fidelity sound

Do you use your factory radio to control your vehicle's audio system with its aftermarket amplifiers? Match's DSP signal processor uses an extensive suite of sonic tools to tune your system to perfection, and its compact size makes it a great option when you don't have a lot of space to spare. As the Match DSP works its magic, you'll hear your music like you were in a recording studio, instead of a noisy vehicle on the road.

Upgrade your stock system for high-fidelity sound

Do you use your factory radio to control your vehicle's audio system with its aftermarket amplifiers? Match's DSP signal processor uses an extensive suite of sonic tools to tune your system to perfection, and its compact size makes it a great option when you don't have a lot of space to spare. As the Match DSP works its magic, you'll hear your music like you were in a recording studio, instead of a noisy vehicle on the road.

The Match plug-in system for input and power

First, you'll need to purchase a vehicle-specific adapter harness that plugs in between your car's stock radio and speakers, supplying signal and power to the DSP. The DSP then transforms the signal from the factory radio into focused, clear, and balanced music, and sends it on to your amplifiers. You can also connect your Match DSP to almost any vehicle without using a vehicle-specific harness, if you're familiar with its wiring.

The ultimate tune-up via PC

If you're a constant tweaker who's crazy about sound quality, then you will have a blast with the Match DSP. It works with your Windows-operated 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 Helix, 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 can enjoy 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

A 30-band graphic equalizer on every channel lets you compensate for all the dips and bumps in your speakers' responses inside your car, so each 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

Once you're done, you simply download your settings to the Match DSP, after saving them on your laptop. The DSP 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 DSP, 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 DSP 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.

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 DSP 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.

IMPORTANT:
If you have experience installing an amplifier and working with your vehicle's electrical system, you should be able to install the Match DSP yourself. If not, please consider having it professionally installed.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
