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.

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.

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.
