The Perfect Sound Processor

After several years of intensive research, development, and engineering, the professionals at JBL have created a revolutionary sound processor for your car. What takes the professional audio tuner weeks to accomplish, the JBL MS-8 accomplishes in minutes. The results are breathtaking. The sound is flawless. It is perfection.

Seamless Integration

The JBL MS-8 is a professional sound processor that improves the acoustics in your car, no matter what type of system you currently have. Although the system is designed for enhancing factory audio systems, it is capable of bringing out the richest sound in aftermarket systems as well. After installation and set-up, the entire system is hidden behind the vehicle's panels or dash, making this a true OEM integration piece. With the MS-8, your factory system will sound better than you ever thought possible.

Fast and easy calibration
with the included LCD display

Simple, Accurate Calibration

Professional tuners will take weeks to fine tune the acoustics of a car audio system. With the JBL MS-8, you will receive results just as good, if not better. And the best part is that it only takes a fraction of the time. Once installed, the calibration is configured by putting on a set of bi-aural microphone headphones, using the included remote control, and following the instruction on the menu-driven system. In approximately 10 minutes, your car system will make the harshest audiophiles jealous. Let the MS-8 do all the hard work for you. Sit back, relax, and enjoy audio like you have never heard before

General Specifications

Equalizer Bands
The number of graphic or parametric equalizer bands the receiver has. The better the EQ, the more likely you will be able to "tweak" your sounds to your desire.
31 band
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-Pass (LP)
High-Pass (HP)
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
2.8 volts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20,000 Hz
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Why did you choose this?
Sonic Electronix Store
I needed a signal processor that would sum channels and flatten the horrible OEM stereo system frequency settings.
Brian M on Jul 14, 2015
I wanted my OEM stereo to sound better, why else would you buy it?
Justin S on May 25, 2015
I read good things about this equipment, so I thought give it a try with my other JBL amps setup :)

Fahad A on Jun 4, 2015
Best sound processor and easiest to use
Shawn S on Mar 26, 2015
Is this unit bluetooth capable?
A shopper on Mar 24, 2015
Best Answer: Your head unit (radio/cd/MP3/tape deck) needs to be Bluetooth capable. This unit or any other type does not offer Bluetooth. If your existing head unit offers Bluetooth, you will have that function.
