LTO

Temperature Compensation: This allows the current in-car temperature to be keyed in. The system uses

this value to compensate for any variation in the speed of sound when calculating time delay.

TIPTIP

This is a feature carried over from the pro audio version of the software and is more applicable to PA applications, in

which it allows the delays to be set during the sound-check and quickly adjusted at the time of the concert if necessary.

The distances between speaker banks in these situations can be quite large and the difference clearly audible.

In the car the improvement will be much more subtle, but one application is in Autosound Competition. Here the demands

for the best possible imaging make even the smallest improvement worth doing. If the temperature inside the vehicle

during the contest is dramatically different from when the system was set-up, here is where you can quickly compensate

for it.

CROSSOVER FILTERS:

The UCS PRO is equipped with independent High-Pass and Low-Pass filters on each of the 6 output channels. For each

filter there are 10 filter type/slope options:

Butterworth type with 6dB, 12dB, 18dB or 24dB per octave slope

Bessel type with 12dB, 18dB or 24dB per octave slope

Linkwitz-Riley type with 12dB, 24dB or 48dB per octave slope

The different filter characteristics can be seen on the PC Editor's graphical display. For each of the filters, the crossover

point can be set between approximately 16Hz and 16kHz. The filter can be bypassed by selecting THRU.

Using both the High-Pass and Low-Pass filters together creates what is known as a Band-Pass filter, most often used for

optimizing the signal destined for midrange and mid-bass speakers. Also for subwoofers, by using the High-Pass as a

subsonic filter typically in the range 16-30Hz.

Parameter Menus & System Set-up

Please note that choosing the Linkwitz-Riley 48dB/octave filter will reduce the number of EQ bands available

on that channel.
