CONTROLS AND FUNCTIONS
1) POWER SWITCH
This switch permits turning the speaker on and off.
2) "MAINS FUSE" FUSE CARRIER
Mains fuse housing.
3) "MAINS INPUT" POWER SOCKET
For connecting the power cable provided.
The connector used for mains connection is a POWER CON® (blue)
4) "MAINS OUTPUT LINK" RELAUNCH POWER SOCKET
For relaunching the mains power. The output is connected in parallel with input (3)
and can be used to power another amplified speaker.
The connector uses a POWER CON® (grey)
5) " BALANCED INPUT" INPUT CONNECTOR
Balanced input at line level. It is able to accept "XLR" sockets.
6) "BALANCED LINK /OUT " OUTPUT CONNECTOR
The "XLR" connector connected in parallel with input (5) can be used to send the
input audio signal to another amplified speaker.
7) "INPUT SENS" INPUT SENSITIVITY CONTROL
This control regulates the sensitivity of the signal amplifier input.
This control does not affect the "BALANCED LINK/OUT" output level
8) "LIMITER" INDICATOR LIGHT
This indicator comes on red to indicate that the internal limiter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads.
9) "SIGNAL" INDICATOR LIGHT
This indicator comes on green to indicate the presence of the audio signal (at a level
of -20dB).
10) "MUTE /PROT " INDICATOR LIGHT
This yellow indicator indicates amplifier status. In normal operating conditions, the
LED is off; if it flashes or is always on, refer to the diagnostics table to check amplifier
status.
11) "READY" INDICATOR LIGHT
This indicator comes on green to indicate that the main power voltage is correct. In
normal operating conditions, the LED is on; if it flashes or is off, refer to the
diagnostics table to check amplifier status.
12) "SET-UP MODE" EQUALIZATION SWITCH
This 10-position rotating switch permits selection of the equalization curve according
to installation type.
See table for corresponding equalization curve.
