INPUT SENSITIVITY
The Input Sensitivity adjustment is used to match the monitor with signal levels from a variety of mixing consoles.
The Input Sensitivity uses DIP switches to match input levels over a 15dB range and are 1dB, –2dB, –5dB,
–8dB, and –11dB. These numbers indicate the input in dBu required to produce an output of 100dB SPL @ 1 meter.
When all switches are in the DOWN position, the monitor is matched to +4dB input level. In the +4dB switch
setting, the monitor is less sensitive to the input signal. In the –11dB switch setting, the monitor is more sensitive
to the input signal.

NOTE: When using the INPUT SENSITIVITY, select only one switch configuration at a time. Engaging
multiple switch configurations (i.e., moving two or more switches up) may cause undesirable operation and
is NOT RECOMMENDED.

AMPLIFIER MUTE
The Amplifier Mute can be used to test system diagnostics by turning off the low frequency or high frequency
amplifier. Although the low and/or high frequency amplifier can be disabled, the preamp and crossover portions
of the circuit are still active. Move the “Mute Woofer” switch UP to turn off the low frequency amplifier. Move
the “Mute Tweeter” switch UP to turn off the high frequency amplifier.
