PRINT: Not a tabbed 'page' like those above, but an important function worth highlighting here. From the FILE menu,
selecting PRINT provides a print-out of all the parameters of the UCS PRO, together with the GLOBAL graph. View it

Parameter Menus & System Set-up
The UCS PRO Features Explained
The UCS PRO has no analog input or output gain controls - level adjustment is handled entirely in the digital domain.
The input stage will accept a maximum input level of 2V rms before clipping.
Click on one of the virtual level slide controls with your PC's left mouse button and hold the button down as you move
the virtual slider up or down with your cursor control. Alternatively, you can enter a dB value directly into the text box below
the slider (type a value and then press ENTER on your PC keyboard).
Clicking on a MUTE button (it will then turn red) will switch out that channel (useful during fault finding and system set-up).
Channel signal PHASE (polarity) can be set to 0 or 180 degrees. This can sometimes improve stereo imaging where
speakers are mounted substantially off-axis. It can also provide a "quick fix" if you find you have wired speakers out of
phase!
GAIN CONTROL SECTION:
11
The input stage of the UCS PRO will accept an unbalanced signal that is typical of many aftermarket head
units (CD players etc.). Where you have a requirement to feed a high level, speaker level or Balanced type
signal from your head unit, use the optional ALTO Mobile UI-2 universal input interface.

TIPTIP
This acts rather like a water-tight valve, allowing signal to pass or not pass through it. Every audio system, especially a
complex one, produces some background noise. By setting the point (level threshold) below which the gate closes, it is
possible to minimize 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 it drops below a selectable THRESHOLD. The RANGE setting dictates the
level range through which the gate will remain closed (usually this will be set to -80dB). The ATTACK and RELEASE times
