SYSTEM OPTIMIZATION
After connecting the ULTIMA SUB-15/LE-1, perform Basic
System Optimization at the listening position. When finished, read
Optimizing Performance with a Test CD, Room Gain Compensation,
and Boundary Compensation (on the next three pages) to see if your
application requires further optimization.

NOTES: The ULTIMA LE-1 is shipped with the CROSSOVER
switch in the ENABLED position, allowing the audio signal to pass
through the internal FM-2 crossover. In a multi-channel system (see
Figure 11 on page 20), be sure to set controller outputs to full range
L/R and no SUB. If applicable, set all other channels (i.e., center, side,
and rear surrounds) to pass 80 Hz and above. Below 80 Hz, signals
will route to the ULTIMA SUB-15.

If you intend to use the subwoofer output from a multi-channel con-

(see Figure 12 on page 21).

BASIC SYSTEM OPTIMIZATION
1. Set all volume controls to minimum positions and all tone
controls to flat. Turn on the audio system power. The ULTIMA
LE-1’s display will remain off for 5 seconds during a self-diag-
nosis test. Upon completion, the display will show one dash
indicating Auto Music Sensor is on, or three horizontal dashes
indicating this feature has been bypassed. Either display indi-
cates that the ULTIMA LE-1 is in standby mode. See
Automatic Music Sensor on page 28 for additional details.

2. Using pink noise as a source, increase the main amplifier’s level
controls to a comfortable listening level.
NOTE: Pink noise can be found on audiophile test and demon-
stration CDs, as well as home-theater controller setup laserdiscs
and DVDs. Do not use the generated noise from a multi-channel
controller, as it is not full-range.
