home listening room conditions. This is because the monitor experiences the upper part
of the room gain range if the cross point is set to 80Hz. Since the room gain effect varies
among rooms, the precise matching of the BESL crossover is left to chance. Therefore I
found that a cross point of 120Hz moves the pass band of monitor above the room gain
curve, and leaves the pass band of the subwoofer completely inside the room gain curve.
In this way, the subwoofer/monitor crossover performs as intended in all rooms.
Furthermore the midrange remains clean since a steep slope is used to reduce bass going
to the monitor. And finally, the subwoofer is "given something to do". With more
separation between the subwoofer subsonic roll off frequency and midrange roll off
frequency, the bass just sounds better.
Tonal balance also varies among listeners and with room characteristics. There is a pre-
programmed global filter (input channels) that adjust "tilting" of the tonal balance
through the midrange and treble. This PEQ filter is centered at 4kHz, and with very low
Q value of 0.25. Simply change the gain of this filter from 0 to -1 to down-tilt the
response from 300 to 10kHz. The top octave and bass octaves are left untouched. The
subjective effect of this filter is to move you further from the performance. It is also
effective for extra "live" sounding rooms or for other overly bright conditions.
Conversely, an overly "dark" condition can be alleviated by using a positive value of
gain, e.g. +1dB on the filter.
Storing and Recalling Programs
It is suggested you save any changes to a new store location. Click Store to.. / Store to
Internal Presets, and then choose a new location in which to create a new program. Also
Click File / Save Set As to store this program to your hard disk. To store ALL the
presets, choose Click File / Save Internal Presets As.. to store the entire set to your hard
disk. It is a good idea to always switch to the Display tab before any store operation.
There is plenty of room left to burn programs directly onto the CD-ROM, thus making
your presets portable with your laptop.
When lost, simply recall any of the programs that begin with '0' as these are factory
settings that were adjusted under echo-free conditions. Then immediately adjust the
overall bass level on channels 1 & 4 again. When really lost you may reload the factory
default programs from your CD-ROM or hard drive. This will be a file with the phrase
"all presets" in the name.
