Setting And Selector - Macrom 44.05 Manuel D'emploi

SETTINGS AND SELECTORS
ON/OFF MODE & HIGH-PASS SELECTOR SWITCH
a) "ON/OFF Low-Pass" MODE: Select the "ON" position
when you want to use the Low-Pass filter section; thus,
only the low frequencies are output at the C-D or F
outputs.
b) "ON/OFF High-Pass "MODE: Select the "ON" position
when you want to use the High-Pass filter section;
thus, only the medium-high frequencies are output at
the A-B or E outputs.
ADJUSTMENT OF LOW&HIGH PASS FREQUENCiES
a) "HIGH PASS": Allows for continuous adjustment of
the High Pass frequency between 50 and 160 Hz, that
is, for the determination of the point where the medium-
high frequencies start.
b) "LOW PASS": Allows for continuous adjustment of
the Low Pass frequency between 50 and 160 Hz, that
is for the determination of the point where the low
frequencies end.
INPUT GAIN ADJUSTMENT CONTROL
In the mid position (click) an input sensitivity of 500 mV is
selected corresponding to the preamplified outputs of
MACROM products.
In case the amplifier is to be connected to a head unit that
is not of MACROM make but is fitted with preamplified
RCA outputs, proceed as follows:
a) adjust the volume control of your head unit to 3/4 of
maximum output level.
b) turn the input gain control by means of a screwdriver
and adjust the input gain from 2 V to 0.1 V in order to
have the maximum sound level with no distortion.
NOTE: Both adjustments are always activated,
independently from the number of inputs, except in case
"c" described at page 13.
