CONTROLS AND FUNCTIONS

1) " BALANCED INPUT 1” AND " BALANCED INPUT 2”INPUT CONNECTORS - Balanced inputs at line level. Accept “XLR” sockets.

2) "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.

3) “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.

4) “SGN” SIGNAL INDICATOR LIGHT - This indicator shows green to indicate the presence of the audio signal (at a level of -20dB).

5) “MUTE” INDICATOR LIGHT - This yellow indicator indicates amplifier status. The LED is off in normal operating conditions.

6) “ON” READY INDICATOR LIGHT - This indicator shows green to indicate that the main power voltage is correct.The LED shows green normal operating conditions

7) “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

8) “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.

9) “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
