Input Jacks, Clip Indicators, Protection

1. Input Jacks

i. Left & Right Input Jacks

The input jacks of the éXcursion1000 are designed for operation with line-level signals. For convenience, parallel XLR and balanced ¼-inch TRS jacks are provided on each side.

Note: The required input level for full power operation, when the Level controls are set to the center detent position, is approximately +4 dBv (1.2 volts). Increasing this setting allows the éXcursion1000 to be driven with sources that have a low signal level. Connecting a signal to both

3. Clip Indicators

Clip Indicator LEDs

The Clip Indicator LED shows when there is excessive input level on either the Left or Right Inputs.

4. Protection

The éXcursion1000 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 situations involving damaging signal levels.

ii.Mono/Stereo Switch

In stereo mode, the éXcursion1000

routes the two signals from the left and right inputs to the corresponding satellite enclosures. If a mono signal is sent to either the left or right channel of the éXcursion1000, enabling the mono mode will route the signal to both satellites. If a stereo signal is used, both the left and right channels will be summed when the mono mode is selected.

2. Level Controls

i. Left & Right Level Controls

The Left and Right Level controls adjust the output level of the corresponding satellite enclosures. Adjustments can be made to alter the balance of the satellites, compensate for signal sources that are not the standard +4 dBv line level or to tweak the SPL levels appropriate to the application. The Left and Right Level are normally set to the center detent.

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.

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.
