20. MIC1 Input
The balanced MIC1 input XLR type has an
impedance of 600ohms. Each zone has aMIC1
Priority Button.
Each zone has a MIC1 priority button. When the
MIC1 priority button is not enabled, MIC1 will be
mixed with the line inputs on each zone (1-8 or L).
When the MIC1 priority button is enabled,MIC1
will take priority over all line inputs (1 - 8 or L)
as well the wall control panel for that zone.
The MIC1 signal will be sent to any extension
Matrix connected to the system.
The MIC1 Gain controls the MIC1 range from
5mV to 300mV.
The MIC1 Bass controls the MIC1 gain at 100hz
(
10dB).

1. Line 1-8 source inputs will be selectable using the
Source Select control on the front of the Matrix. 2)
2. The selected source input number will be indicated
on the Matrix zone display.
3. Any extension Matrix unit connected to the system
will use sources line 1-8 from the master Matrix.
4. Only one set of input sources for lines1-8 can will
be connected per system.
Up to two paging consoles can be
connected to the system simul
-taneously
via the two paging con
-sole Rj45 input ports. The paging
consoles will have equal priority
and will operate on a first come
first served basis . The RJ45 pin
assignment order is as below:
The Paging MIC Gain control will adjust the Paging
MIC Input Signal Level. Each Paging MIC will have
its own gain control.There by each Paging MIC can
be set independently of the other Paging MICs.
The Line Inputs have an impedance of 47 kohms.
18. Paging Console Inputs
MIC1 will have priority only on Zones where the
MIC1 Priority Switch is enabled on the front panel.
Zones where the MIC1 priority switch is not enabled,
MIC1 will mix with the Source Selected for the Zone.
The MIC1 level will be controlled by the MIC1 Level
Adjustment Knob and the Master Level Adjustment
Knob.
