-The TERMINATOR II will detect and remove feedback by placing notch filters
on the proper frequencies. Continue to slowly raise the gain until all
feedbacks have been eliminated, then exit from SETUP Mode by pressing
and releasing the BYPASS button quickly.
All LED turn ON for few seconds, indicating fixed filters are STORED and
automat ically LIVE Mode is selected, the remaining filters are available in LIVE
MODE.
If all 24 filters have been used in SETUP Mode, the SETUP Mode is left
automatically and no more filters are available in LIVE Mode.
2. Using LIVE Mode (REAL TIME)
The TERMINATOR II operates normally in LIVE Mode (24 notch filters minus
the fixed used filters ). Live Mode filters are set on the feedback frequency
as soon as a new feedback is detected, according to the knob position of
the sel ected LIVE Mode Variations (from MUSIC to SPEECH).
If all LIVE filters are used and a new feedback occurs, the oldest LIVE filter
is cleared and reallocate to the new feedback frequency (the correspondent
led will light).
The TERMINATOR II will continue to search feedback frequency through the
LIVE notch filters.

4. USER SETUP
5 AUTOMATIC FILTER RELEASE
The ALTO TERMINATOR II provides the user with 24 notch filters, for each
channel, they are enough for normal performances. If several
numbers of filters are required, (more than 16), we strongly recommend to
operate a new setup of the sound system.
Anyway, even if the TERMINATOR II uses very narrow notch filters, accordingly
with the selected application type, unused notch filters must be avoided, to
always guarantee the best audio performance.
The TERMINATOR II constantly monitors the status of the LIVE filters and
automatically removes the ones that are no longer necessary.
