Control And Inicators - Macrom 45.40 Manuel D'emploi

1 • FRONT/SUB INPUT CONNECTORS: Connect the pre-output leads of the head unit to the
input connectors of the amplifier. This input will drive the end section of both the FRONT
section and the SUB one.
2 • REAR INPUT CONNECTORS: Connect the pre-output leads of the head unit to the input
connectors of the amplifier. This input will drive the end section of the REAR section.
3 • 4CH/2CH INPUT MODE SELECTOR:It allows to select the amplifier's input configuration
as follows:
a) "4ch" - the operation of the five channels depends upon the connection
of the four input channels
b) "2ch" - utilize the FRONT/SUB inputs to drive the five channels by
means of two inputs only.
4 • FRONT CROSSOVER SELECTOR: Il allows to select the FRONT amplifier's operation
mode:
a) "FLAT": the FRONT amplifier reproduces the whole audio range on
grounds of the signal present at its input;
b) "63 Hz": the High-Pass crossover is activated at 63 Hz to determine the
starting value of the high frequencies present at FRONT outputs;
c) "80 Hz": the High-Pass crossover is activated at 80 Hz to determine
the starting value of the high frequencies present at FRONT outputs.
5 • FRONT INPUT GAIN ADJUSTMENT CONTROL: It allows to adjust input sensitivity to the
FRONT section from 200 mV to 4 V.
6 • REAR CROSSOVER SELECTOR: It allows to select the REAR amplifier's operation
mode:
a) "FLAT": the REAR amplifier reproduces the whole audio range on
grounds of the signal present at its input;
b) "63 Hz": the High-Pass crossover is activated at 63 Hz to determine the
starting value of the high frequencies present at REAR outputs;
c) "80 Hz": the High-Pass crossover is activated at 80 Hz to determine
the starting value of the high frequencies present at REAR outputs.
7 • REAR INPUT GAIN ADJUSTMENT CONTROL: It allows to adjust input sensitivity to the
REAR section from 200 mV to 4 V.
8 • SUB CROSSOVER SELECTOR: It allows to select the crossover frequency of the SUB
amplifier:
a) "50 Hz": the Low-Pass crossover is activated at 50 Hz to determine the
end point of the low frequencies present at SUB output;
b) "80 Hz": the Low-Pass crossover is activated at 80 Hz to determine the
end point of the low frequencies present at SUB output;
c) "120 Hz": the Low-Pass crossover is activated at 120 Hz to determine
the end point of the low frequencies present at SUB output.
9 • SUB INPUT GAIN ADJUSTMENT CONTROL:
It allows to adjust input sensitivity to the Sub section from 200 mV to 4 V.
