sensitivity needs to be improved, it can be set as 1V and 2V through jumper according to the operation method of
the prior input module. Please refer to descriptions of item 1-3.1.
Input signals of 8 lines of the
normal input module
are processed separately as 8 independent sound sources to
enter the system, and they correspond to the 8 sound sources on the main interface of the screen (default).
The users can choose to purchase 6
normal input modules
at most, and these modules are set by the distributor,
corresponding to No.“9 ~ 48” sound source.

Partition Output Module
(
M2864
)
Each partition output module is provided with 8 signal output ports, respectively corresponding to 8 audio signal
input interfaces that connect 8 primary and 1 standby smart amplifier, or connecting with audio input interfaces of
other amplifiers.
The nominal output level of the partition output is 1V (0dBV).
When the system has only 1 output module, the 8 signal output ports correspond to No.“1, 2, 3, 4, 5, 6, 7 and 8”
partition on the main interface of the screen (default). If there are more than 8 partitions in the user’s system,
several
partition output modules
shall be used. One
partition output module
shall be added for every 8
partitions increase. The partition number to which each output module corresponds is determined by the
distributor through hardware setting of the module. At most, 250 partitions can be set, requiring 33
partition
output modules
in total.

Fire control/disaster
alarm input module
(EMC Input Module –
M2880
)
The module is the connector between the broadcasting system and
the fire control center. Type D port with 25 pins (EMC Input
Individual) should be connected to the fire control center, and
each port can receive 16 lines of alarm signals.
Functions of pins of the port are as follows:
Pin 1~16:
hot end, respectively respond to control signals of line
1~16 of alarm input of this module;
pin 17
~
25:
cold end
(common terminal), “ground” of the alarm signals.
If there are more than 16 lines of alarm signals, then it is necessary to use several
alarm input modules
. At most
16
alarm input modules
can be used to receive 256 lines of alarm signals of the fire control center. The serial
number of each module is determined by the distributor through hardware setting of the module.
