ii. Subwoofer
Level Control
The
Subwoofer
Level
control allows
fine-tuning of the
low frequency
output. Adjustments
can be made to
compensate for
signal sources that
are not the standard
+4 dBv level.
3. Clip
Indicators
i. Clip Indicator
LEDs
The
Clip Indicator
LED
shows when there is ex-cessive input level on
either the
Left
or
Right
Inputs.
ii. Sub Clip Indicator LED
The
Sub Clip Indicator LED
indicates excessive
levels for signals going to the subwoofer
amplifier. Indications of excessive levels are
monitored either from the signals being sent from
the
Left
and
Right Inputs
or from the
Aux Bal
Subwoofer In
jack.
4. Protection
The
éXcursion 2000
uses a sophisticated,
multi-
stage
limiting system that prevents clipping of the
amplifiers while accommodating a wide range of
input levels. The limiter circuitry protects the entire
system against most instances of overpowering.
Note:
Continuous acoustic feedback may cause
damage to the light bulbs (CTL™ horn protection
circuitry) or to the speakers in the satellites.
i. Limit
Indicator LED
The
Limit Indicator
LED
indicates
when the maximum
operating level for
the satellites has
been reached.
When the
LED
is
illuminated, the
circuitry is actively
limiting the output.
Increasing the
input signal level
or turning up the
Level
controls will
not increase the
operating level
beyond the limit
indicated. When the unit is driven into limiting, the
internal
Limiter
circuit becomes triggered and will
reduce the gain. This will not significantly degrade
the sound quality.
Note:
Operating a few dB into limiting will
ensure that the system is operating at its
maximum output. Operating excessively into
limiting will make the system more susceptible
to feedback.
ii. Sub Limit Indicator LED
The
Sub Limit Indicator LED
illuminates when
the maximum recommended operating-level of
the subwoofer has been reached. Increasing the
input signal level or turning up the
Level
controls
will not increase the operating level beyond
the limit indicated. When the internal
Limiter
circuit becomes active the sound quality will not
significantly be degraded.
