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 music applications, when the system plays on a

ﬂoor stand. For monitoring applications, when the system is on the ﬂoor, “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.

WARNING: the VDE Power Connector is used to disconnect the system from

the power supply network. It shall be easily accessible after the installation

and during the use of the system

The XLR connectors

use the following AES standard:

PIN 1 = GROUND (SHIELD)

PIN 2 = HOT (+)

PIN 3 = COLD (-)
