- Be sure to replace the unit’s terminal cover after connection completion. Because high voltage is applied to the speaker terminals, never touch these terminals to avoid electric shock.
- Be sure to ground to the safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe as a catastrophic disaster may result.
- Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down, causing personal injury and/or property damage.
When the Unit is in Use.
-
Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest ArtSound dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock. • If you detect smoke or a strange smell coming from the unit.
• If water or any metallic object gets int o the unit
• If the unit falls, or the unit case breaks
• If the power supply cord is damaged (exposure of the core, disconnection, etc. )
• If it is malfunctioning (no tone sounds.) -
To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest ArtSound dealer.
-
Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
-
Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as this may result in fire or electric shock.
Caution.
When Installing the Unit.

1. DIP SWITCHES
Dip switches set the Matrix system address. If the system is to be expanded,
each MAT-8000 unit must be defined as Master, Slave1, 2 or 3. If you are
expanding the system, only line in puts 1-8, MIC 1 and 2 x Remote Paging
Consoles of the Master Matrix are enabled. All Slave Matrix units connected
to the Master will use the Master Matrix inputs. For the avoidance of doubt,
if a Matrix unit is configured as a slave, the slave Matrix Inputs1 – 8, MIC1
and remote paging consoles inputs will be disabled.
However, the optional wall plates (WP-8000B and WP8000C) can be used to
operate these additional zones. Dip switch settings are as follows for
configuring the MAT-8000 as a Master or Slave:
2. EVAC / FIRE SYSTEM INTERFACE (7 WAY PHEONIX CONNECTOR)

PIN 4 – [ALERT DRY CONTACT]
The built-in alert voice message will be broadcast to all 8 zones after
triggered by dry contact between ALERT and COMMON.
PIN 5 – [EVAC DRY CONTACT]
The built-in EVAC voice message will be broadcasted to all 8 zones after being
triggered by dry contact between EVAC and COMMON.
PIN 6 – [EMC IN]
An optional external voice alarm message may be broadcasted to all 8 zones of
the system, when an alarm signal is detected from an external voice message
generator. Fire alarm, alert, EVAC and EMC in are of equivalent priority.
3. TONE OUTPUT
The Tone Output Volume Control will adjust the output level of the FIRE ALARM,
ALERT, EVAC voice messaging.
4. EMC INPUT

The extension link connectors enable 8 zone Matrix units to be connected
together to form a larger system.
Up to four 8 Zone Matrix units can be connected to make a 32 zone system.
The Matrix can be linked with a DB37 Cable. This will enable the Line 1-8
Sources, MIC1 input, Paging Consoles 1 & 2, and Communication Data of the
master unit to be shared with any Slave Matrix Units connected to the system.
6. REMOTE SOURCE
Each zone can have a remote line level source connected.
The remote source input connector is shown here.
This has been designed to be used if you don’t wish to use a local in wall
mixer. This could be for example,a Radio MIC.
On selecting this input via the front panel controls, select “L”. Please note
that this input cannot be distributed to other zones.
Local zone source level has three adjustments, namely:
a. Gain control for the local source Input on the rear of the Matrix
b. A Music level control on the Matrix front panel or the remote wall control
c. A Master level control on the Matrix front panel.
Please Note: The input signal is set at 300 mV – 1.1 v/10 K Ohm
7. REMOTE CONTROL PANEL INPUT
Each of the eight zones can have a remote control panel connected. The Remote
control Panel will enable the source and volume to be controlled from a remote
location. Each zone has its own RJ45 input connector allowing for a Remote
Control Panel to be connected for control over each zone.
Local Source Connections are as follows:
- A remote wall panel can be connected to the Matrix, with only one remote wall controller able to be connected per zone.
- The remote wall panel will be selectable on the system. Therefore, selectable sources will be L (local) as well as source line1 to 8.
The RJ45 pin assignment is as follows:
- RS485 B
- RS485 A
- GND
- 24V (OUT)
- GND

NOTE: Only Enable when a Zone Remote Wall Control Panel is connected.
14. REMOTE SOURCE GAIN
The Zone Local Source Input Signal Level can be adjusted from 190 mV to 200 mV
using the Remote Source 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. Every Zone Remote Source
Input has a Gain Control.
15. FIRE ALARM
There are Fire Alarm dry contacts for zones 1-8. When Dry Contact is detected
the EMC Input will be open and take priority over all other inputs.
The EMC Input will only take priority and broadcast to zones where there is a
Zone Fire Alarm Dry Contact Closure. Each zone has a separate Fire Alarm Dry
Contact. Fire alarm, alert, EVAC and EMC in are of equivalent priority.
16. LINE GAIN
The System Line Source Input Signal Levels can be adjusted from 190mV to 200mV
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 separate Gain Control.
17. 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 Phono Connector, which will enable a
Stereo Source Signal 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 have an impedance of 47 K Ohms
- Line 1-8 source inputs will be selectable using the Source Select control on the front of the Matrix.
- The selected source input number will be indicated on the Matrix zone display.
- Any extension Matrix unit connected to the system will use sources line 1-8 from the master Matrix.
- Only one set of input sources for lines 1-8 can be connected per system.
18. 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 served basis. The RJ45 pin assignment order is as below:
19. 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.
20. MIC1 INPUT
The balanced MIC1 input XLR type has an impedance of 600ohms. 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.
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.
The MIC1 signal will be sent to any extension Matrix connected to the system.
21. MIC1 GAIN
