We stay on top of new products and technologies to help people make informed choices.
Overview: 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
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
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.
