JACK/FEMALE XLR INPUTS (BAL/UNBAL). The system accept jack or XLR
input connectors. These balanced inputs can be used to connect balanced or
unbalanced microphones or audio sources at line level. The balanced connector
is connected in parallel and can be used to send the audio signal to other
amplified speakers, recorders or supplementary amplifiers.
LIMITER LED. The amplifier has a built in limiter circuit to prevent clipping
of the amplifiers or overdriving the transducers. When the soft clipping circuit
is active the LED blinks RED. It is okay if the limit LED blinks occasionally. If the
LED blinks frequently or lights continuously, turn down the signal level.
SIGNAL LED. The signal indicator lights green if there is signal present on
the main input.
POWER STATUS LED. This green led is ON when the speaker is connected
to the main power supply and the ON/OFF is in ON position.
MALE XLR SIGNAL OUTPUT. The output XLR connector provides a loop
trough for speakers daisy chaining.
VOLUME CONTROL. Adjust the amplifier volume. This control does not
affect the “Link” - “Input - Link” output level.
FLAT/BOOST SWITCH. Set the flat or boost equalization. “Boost” equalization
is a loudness recommended for background music applications, when the
system plays at a low level. For all other applications “Flat” equalisation is
recommended.
INPUT SENSITIVITY SWITCH. Position the switch in LINE to use a line level
source (0 dB) or MIC to use a microphone source.
IEC AC SOCKET. The IEC AC socket connect the power cord to the socket.
FUSE CARRIER. Mains fuse housing.
POWER MAIN SWITCH. The power switch turns the AC power ON and
OFF.
