ZM8 Matrix Zone System
User Manual
12
37. Line gain
The system line source input signal levels can be adjusted from
195mV - 2V using the line source input gain control. This will enable the
signal level of all sources to be equalized there by ensuring output volume
level remains constant when switching from one source to another
source.
All system source inputs L (lines 1-8) have a seperate gain control.
38. Line inputs
The system has 4 line inputs, as well as 4 inputs selectable as MIC or line
with phantom power available.
Every line source input has a dual RCA photo connector, which will enable
a stereo source sugnal to be connected. Note: however this is a mono
system and a stereo input will be combined to give a mono output.
The line inputs will have an impedance
of 47kΩ.
1. Line 1-8 source inputs will be selectable using the source select control
on the front of the Matrix.
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 the lines 1-8 can be connected per
system.
39. Paging console inputs
Up to two paging consoles can be
connected to the system
simultaneously via the two paging
console RJ45 input ports. The
paging consoles will have equal
priority and will operate on a first
come first serve basis. The RJ45
pin assignment order is as below:
1. RS485B
2. RS485A
3. GND
4. +24V (OUT)
5. GND
6. +24V (OUT)
7. AUDIO IN +
8. AUDIO IN -
40. Paging MIC gain
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.
41. MIC 1 input
The balanced MIC1 input XLR type has an impedance of 600Ω. Each zone
has a MIC1 priority button.
Each zone has a MIC 1 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 MIC 1 priority button is enabled, MIC1 will take priority over
all line inouts (1-8 or L) as well as the wall control panel for that zone.
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 the source selected for the zone. The MIC1 level
will be controlled by the MIC1 level adjustment know and the master level
adjustment knob.
The MIC1 signal will be sent to any extension Matrix connected to the
system.
42. MIC1 gain
The MIC1 gain controls the MIC 1 range from 5mV to 300mV.
43. MIC1 LF bass
Adjust clockwise to increase or anti-clockwise to decrease the low
frequency (bass) contour for the MIC1. Centred at 100Hz (±10dB).
44. MIC1 HF treble
Adjust clockwise to increase or anti-clockwise to decrease the high
frequency (treble) contour for the MIC1. Centred at 100Hz (±10dB).
45. Balanced MIC/LINE inputs
46. Balanced input function select
