3. GND LIFT switch
This switch lis the ground of the balanced audio input from the earth-ground of the amplier. If you have HUM noise
problems on one or more loudspeakers try to change the posion of these switches (oen all up or all down for all the
ampliers in the system). Please note that to have an eect all cables must be balanced.
4. LEVEL control
Rotary level control: it aenuates the level of the signal sent to the LINE input. The aenuaon ranges from “0” fully
closed (the signal is completely aenuated) to “10” fully open, nominal level (the signal is not aenuated in any way,
so it is fed to the internal amplier at the same level at which it arrives on input).
5. SIGN / LIMIT indicator
GREEN LED illuminates to indicate the presence of the signal at the amplier input.
RED LED illuminates when the internal amplier's output is limited.
NOTE: When this LED ashes reduce the input signal level.
6. PRESET MONITOR/FOH selector
This switch allows the selecon between two equalisaon sengs, suited to two dierent uses.
MONITOR: suited for stage monitoring sound reinforcement for an improved feedback rejecon.
FOH: this preset has been designed for typical sound reinforcement applicaons with the speaker mounted on oor
stand.
7. POWER switch
Speaker is "ON" when the switch is in the "I" posion.
NOTE: When you shut down your equipment, turn o the speaker rst. When powering up, turn on the speaker last.
8. ON indicator
GREEN LED: when lighted indicates that the amplier has been turned on and AC power is available.
9. AC~ socket
Here’s where you plug in your speaker’s mains supply cord. You should always use the mains cord supplied with the
speaker. Be sure your speaker is turned o before you plug in the cord.
