It is important to optimize the Input and Output Gain settings of the UCS PRO to ideally match the output from
your car audio head unit and the input stage of your power amplifier(s). The optimum settings will ensure the
lowest possible noise and no distortion.
While set-up by ear is possible, the best results will require use of a voltmeter and oscilloscope, and this is
therefore generally best left to a professional installer.
Every audio system, especially complex ones, produce some background noise.
A Noise Gate acts like a valve, allowing signal to pass or not pass through it. By setting the point
(
) below which the gate closes, it is possible to effectively eliminate noise at those times when
it is most likely to be audible, such as during the pauses between tracks on a CD.
The noise gate cuts signal output whenever the signal level drops below a presetable (THR).
The (RG) setting dictates the level range through which the gate will remain closed (usually this will
be set to 80dB). You can set the so that the gate closes below the but re-opens at a
point somewhere further below that threshold. In this way the gate can be made to operate on a specific
signal level segment, but the need to use it in this way in-car would be rare.
The (AT) and (RL) times relate to the speed with which the noise gate closes and opens. The
default settings will usually be fine and provide gating that works transparently, but you can use these
settings to optimize the results.
Finding the best settings will be a matter of experimentation and will depend on several factors such as
quality of source material (CD, tape), musical genre and how well signal gains are matched throughout the
audio system.
