Control And Indicators - Macrom 44.50 Manual De Instrucciones

1 • FRONT INPUT CONNECTORS: Connect the pre-output leads of the head unit to the input
connectors of the amplifier. This input will drive the end stage of the FRONT section.
2 • FRONT INPUT GAIN ADJUSTMENT CONTROL: input sensitivity ranges from 200 mV to
4V.
If the amplifier is to be connected to a head unit that is fitted with preamplified RCA outputs,
proceed as follows:
a) set the volume control of your unit to 3/4 of maximum output level;
b) set the input gain control to the point where the maximum sound level with no distortion is
obtained.
3 • FRONT CROSSOVER SELECTOR: it allows to select the output
mode of the amplifier by activating either the High-Pass or the Low-Pass
filter.
a) Flat: the amplifier reproduces the whole range of frequencies from
20 Hz to 20 kHz;
b) High-Pass: the amplifier reproduces a range of frequencies from
20 Hz to 30 Hz or from 20 Hz to 600 Hz as well as from 30 Hz to
600 Hz;
c) Low-Pass: the amplifier reproduces a range of frequencies from 20
Hz to 30 Hz or from 20 Hz to 600 Hz as well as from 30 Hz to 600 Hz.
4 • CONTINUOUS ADJUSTMENT OF THE FRONT HIGH-PASS AND LOW- PASS
FREQUENCIES: after positioning the filter, either High-Pass or Low-Pass, frequencies can be
adjusted between 30 and 600 Hz .
5 • 4CH/2CH INPUT MODE SELECTOR: it allows to select the amplifier's input configuration
as follows:
a) "4ch": the four input connectors have to be all connected to the pre-amplified outputs of
the unit to drive the four amplifier channels;
b) "2ch": to drive the four channels just the two Front input connectors have to be connected
to the pre-amplified outputs of the unit.
6 • 4CH/3CH/2CH OUTPUT MODE SELECTOR: it allows to select the amplifier's output
configuration as follows:
a) "4ch": 4 output channels are working, therefore the amplifier configuration can be as
follows: four stereo channels;
b) "3ch": 3 output channels are working, therefore the amplifier configuration can be as
follows: two stereo channels and one mono channel;
c) "2ch": 2 output channels are working, therefore the amplifier configuration can be as
follows: two mono channels.
7 • REAR CROSSOVER SELECTOR: it allows to select the output mode of the amplifier by
activating either the High-Pass or the Low-Pass filter.
a) Flat: the amplifier reproduces the whole range of frequencies from
20 Hz to 20 kHz;
b) High-Pass: the amplifier reproduces a range of frequencies from
20 Hz to 30 Hz or from 20 Hz to 600 Hz as well as from 30 Hz to
600 Hz;
c) Low-Pass: the amplifier reproduces a range of frequencies from
20 Hz to 30 Hz or from 20 Hz to 600 Hz as well as from 30 Hz to
600 Hz.
