CONNECTING THE MSB2
To carry out the connection of this module you should follow the steps indicated in the figure on next page.
Place a minijumper to enable or disable the subsonic filter (ON/OFF). Do this for each section: MJ101 in section A and
MJ102 in section B (Indication nr.1).
ATTENTION: This minijumper must be set ON or OFF. If the minijumper is not inserted at all, the module will not work
properly.
Insert and screw the module and the chassis together in the front and back panels.

MODULE FOR EXTERNAL BGM SELECTION AND GENERAL VOLUME CONTROL. THE
MODULE
HAS
TWO
AMPLIFICATION MODULES.
DESCRIPTION
This module consists of two sections. Each of these sections can be connected to a
amplification module (MP30/MP60/MP120) or external amplifier control module (MCA1).
From this module you can externally select the desired BGM for the zones assigned in the
amplification module. If more than one BGM is selected for the same zone, the lowest
order BGM will be used.
This module also offers a general volume control for each section and is always accessible
for instant control. The volume control will act as a general gain for the output signal of
the amplifier module to which it is connected. As all connections are internal, this module
has a blank back cover-plate.
SUBSONIC
: on, off
BGM1
: When set ON, BGM1 is selected for the corresponding amplifier.
BGM2
: When set ON, BGM2 is selected for the corresponding amplifier, only if BGM1 is not
ON.
BGM3
: When set ON, BGM3 is selected for the corresponding amplifier, only if BGM1 or
BGM2 are not ON.
BGM4
: When set ON, BGM4 is selected for the corresponding amplifier, only if BGM1, BGM2
or BGM3 are not ON.
NOTE: Remember that just one BGM should be selected. If there is more than one BGM
selected, the lowest order BGM will be used. For example: If in Section A BGM1 and BGM3
are selected, the module will select BGM1 as default.
