The MTX re-Q5 is a 5-channel volume sensing bass restoration device designed to restore bass when adding aftermarket amplifier to a factory audio system. Most OEM systems "roll off" the bass to avoid damaging the speakers at higher volume levels. While this is acceptable when using stock speakers, it's not desired when adding amplifiers as it limits the low frequency output of your system. The MTX re-Q5 solves this problem by sensing the input from the head unit to add more bass at high volume levels and balances the bass response at lower volume levels. You get the bass you want with added performance while keeping your factory radio and your steering wheel controls.

Balance Bass Enhancement

Rather than just turning up the bass linearly, the re-Q5 senses the factory radio output and adjusts its boost level to balance the sound of all 5-channels in your system (Right Front, Left Front, Right Rear, Left Rear, and Sub). You can select for the re-Q5 to perform its Balance Bass Enhancement after or before the factory amplifier.

Smart Engage

An input signal sensing circuit turns the re-Q5 on automatically. There is also a remote turn-on input if you prefer not to use the Smart Engage feature.

Speaker Level Input

There are speaker level inputs for the Front Left/Right, Rear Left/Right and Subwoofer channels. The compatible input range is 250 mV to 30 V. If your factory system has no sub, the re-Q5's sub output is taken from the left and right inputs.

Line Level Output

The line outputs for Front left/right, Rear Left/Right and Sub are individually adjustable. The maximum output is 2.5 ...

Line Level Output

The line outputs for Front left/right, Rear Left/Right and Sub are individually adjustable. The maximum output is 2.5 volts for the full range channels and 8 volts for the sub.

Crossover

The subwoofer channel's crossover is continuously adjustable from 40 Hz to 200 Hz.

Subsonic Filter

The subsonic filter is continuously adjustable from 10 Hz to 40 Hz.

Front/Rear Sub Level

In some applications it may be necessary to reduce the low frequency output of the full range outputs on the re-Q5 when summing a factor subwoofer signal with full range signal. This is due to variances in the input signal which are inherent to some factory audio systems. After the re-Q5 is connected, if the low frequency output of the front or rear speakers is too high regardless of gain settings, you can adjust the settings on the Sub Level Front and Sub Level Rear switches to -3dB or -6dB. This will reduce the low frequency output on the front and rear full range outputs.

Auxiliary Module

The MTX re-Q5 comes supplied with a wired Auxiliary module and a 16.5' connection cable. The Auxiliary module features a 3.5mm input jack for connecting an external audio source. The supplied 16.5' connection cable and integrated mounting flanges on the module allow you to mount the Auxiliary interface in the front of your vehicle. The Auxiliary module features its own on/off-volume control knob. The Auxiliary interface measures 3.155" wide x 0.905" tall x 2.015" deep.
