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 OFF (left) 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 ON) may cause undesirable operation and
is NOT RECOMMENDED.

NOTE: When using the Bass Roll Off, select only the 30Hz or 60Hz filter. Engaging both switch configura-
tions at one time (both switches ON) may cause undesirable operation and is NOT RECOMMENDED.
BASS ROLL OFF
The Bass Roll Off is a subsonic filter used to limit harmful frequencies sent to the low frequency transducer to
prevent overexcursion. The filter is selectable to electronically limit frequencies below 30Hz or 60 Hz at a 12
dB/octave roll off. When both switches are in the OFF (left) position, the amplifier has an electrical -3dB
down point of 28Hz. For optimum operation select only one switch configuration at a time.
