Quickstart Guide 9
7. Bass Control
The bass control provides ±6 dB of shelving at 80 Hz. Always use equalisation sparingly,
aiming to cut rather than boost especially when the loudspeaker is used near boundaries such as
walls or fl oors.
8. Power On Indicator
Blue LED illuminates when mains power is applied to the loudspeaker and powered up via the
rocker switch.
9. Signal Indicator
Illuminates green when the signal level reaches -6 dB, and is a useful indicator of the input signal
approaching the limiter threshold.
10. Limit Indicator
Illuminates red when the signal level approaches maximum and the limiters start working.
Frequent and/or continuous lighting of limit LED indicates overdriving. If this occurs reduce the
input level to the loudspeaker or enlarge your system with additional loudspeakers.
11. Front LED Status
The function of the illuminated front badge can be toggled between permanently on,
permanently off, or to indicate action of the limiting circuits.
12. Mic / Line Switch
Selects the input for that channel to accept either a low level, low impedance microphone,
or a high level, high impedance source such as a mixing console, keyboard or acoustic
instrument with onboard electrics. The mic input is not suitable for condenser microphones that
require phantom power.
13. Level Control
Rotary level control which attenuates the input signal level of the connected instrument /
line source for that input channel. The range (mic) is from -∞ (MIN) to +68 dB (MAX) and (line) from
-∞ (MIN) to +38 dB (MAX).
