CONTROLS AND FUNCTIONS

" BALANCED INPUT 1" AND " BALANCED INPUT 2"INPUT CONNECTORS

Balanced inputs at line level. Accept "XLR" sockets.

" OUT 1 " AND " OUT 2 " OUTPUT CONNECTORS

The "XLR" connectors be used to send the input audio signal to another amplified

speaker.

The signal is choosing between "LINK/XOVER" (10) switch.

"LIM" LIMITER INDICATOR LIGHT

This indicator shows red to indicate that the internal limiter starts working.

This prevents amplifier distortion and protects the speakers against overloads.

"SGN" SIGNAL INDICATOR LIGHT

This indicator shows green to indicate the presence of the audio signal (at a level of -

20dB).

"MUTE" INDICATOR LIGHT

This yellow indicator indicates amplifier status.

The LED is off in normal operating conditions.

"ON" READY INDICATOR LIGHT

This indicator shows green to indicate that the main power voltage is correct.

The LED shows green normal operating conditions

"SUBWOOFER LEVEL" INPUT SENSITIVITY CONTROL

This control adjusts the sensitivity of the signal amplifier input.

This control does not affect the " OUT 1 " and " OUT 2 " outputs levels

"PHASE" SWITCH

This two-position switch permits turning the audio signal's phase by 180°.

Rotation makes it easier to optimise the reproduction of the low frequencies even in

the most difficult installation situations. After completing installation, play a piece of

music and move the switch to achieve the best sound reproduction at low

frequencies.

"XOVER" SWITCH

This switch permits selecting the crossover frequency between the

subwoofer and the speakers connected to the "OUT 1 " and "OUT 2 " outputs.

Choice depends on the type of speaker used for reproduction of mid-high

frequencies.

For speakers with 12" cones, it is best to use 120Hz, while with 15"

speakers 90Hz.

10)

"LINK/XOVER" SWITCH

This switch allows to select the signal type to send "OUT 1 " and "OUT 2 " outputs.

The "LINK" position allows to link the same input signal.

The "XOVER" position allows to send input signal according to crossover frequency

select by XOVER (9) switch.

11)

"MAINS INPUT" POWER SOCKET

For connecting the power cable provided.

The connector used for mains connection is a POWER CON® (blue) socket.

12)

"MAINS LINK" POWER SOCKETS

For linking the mains power. The outputs are connected in parallel with input (11) and

can be used to power other active speakers.

The connectors are POWER CON® (grey) sockets.

13)

"MAINS FUSE" FUSE CARRIER

Mains fuse housing.

14)

COOLING GRILLE

These grilles permit cooling the amplifier during operation.

Do not block accesses and clean the grilles whenever necessary to ensure correct

air circulation.

CHARACTERISTICS

Cooling

The amplifier is cooled by means of the aluminium panel placed on the back of the speaker.

The thermal protection is ensured by an internal circuit which controls the temperature of

the amplifier and protects this against any risk of overheating thus limiting in proportion the

general volume ( temperature >70°C).

If the temperature reaches the maximum operating temperature (>80°C), the audio signal

is set to the "MUTE" position and it will be indicated by the switching on of the yellow

"MUTE" LED.

The requiriered volume and all functions will be restored automatically when the normal

operating temperatures are reached.

Protections

When the yellow "MUTE" LED turns on, it means that a malfunction has been detected on

the speaker, thus setting this to the mute position.

Perform the checks listed below:

Check if the speaker is properly connected to the power supply.

Make sure that the power supply is of correct voltage.

Check that the amplifier is not overheated.

Disconnect the speaker from the mains power supply, wait for a few minutes and

connect it again.

If after these tests the yellow "MUTE" LED is still on, please contact an authorised service

centre.
