TOTAL RECALL Features Explained
A wide ranging amount of time delay, from as little as 21 microseconds (0.021ms, equivalent to a distance of a little
over 7mm), can be set on each of the channels. This is commonly known as 'Time Alignment'.
Values can be input as
distance (millimetres/meters) or time (microseconds/milliseconds).
The amount of delay is usually calculated from physical measurements of the distances between the various speakers
and the driver's ears. The delay compensates for the difference in speaker mounting positions, with the speaker furthest
away (commonly the woofer in the trunk) being the reference point to which all other speakers are aligned (delayed).
When applied correctly to all speakers in the system, the result is an improvement in the apparent stage position, height,
depth and the location and focus of the performers on the 'virtual stage' that extends across the dashboard. There should
also be the feeling that the low bass is coming from ahead of you, even where the woofer is physically behind you.

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. 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 neces-
sary. It can also be useful in some automotive situations.

TOTAL RECALL is
equipped with independent High-Pass filters for each of the Front & Rear channels, and a Low-Pass
filter for the Subwoofer channel. For each filter there are 9 filter type/slope options:
The different filter characteristics can be seen on the PC EDITOR's graphical display. The filter point can be set between
16Hz and 16kHz, or each filter can be bypassed by selecting
