3. GENERAL DESCRIPTION
TOA's M-9000 Matrix Mixer is designed to be used in conjunction with optional modules and can be
configured for up to 8 inputs and 8 outputs. Usable modules include 4 types of 9000 series plug-in modules,
D-001T (for 2 channels of input), T-001T (for output expansion), C-001T (for remote control), and ZP-001T (for
zone paging), as well as 900 series input modules. The most appropriate modules can be selected depending
on applications.
By changing operation mode, the M-9000 Mixer can be used either as a matrix system suited to BGM or
paging broadcasts, or as a mixer that is appropriate for speech or sound reinforcement applications. It is
equipped with signal processing and control functions, permitting all parameters to be set at the mixer.
Further, settings data can be stored inside the mixer and called up using the keys on the front panel.
The 9000 Series A-9060DH and A-9120DH Amplifiers feature the M-9000's matrix mixer function and come
with two 60 W and two 120 W power amplifiers, respectively. Both amplifiers can individually perform multichannel broadcasts.
4. FEATURES
• Either matrix or mixer*1mode can be selected depending on application for optimum operation.
• Matrix mode for BGM broadcasts or paging to zoned areas can be selected.
• A mixer mode*
1
can be used for speech or sound reinforcement in such applications as hotel meeting
rooms, churches or conference rooms.
• Eight module slots enable audio input and output configuration ranging from 1 input and 2 outputs to 8 inputs
and 8 outputs.
• All settings can be performed at the unit using the built-in vacuum fluorescent display (VFD), setting keys
and Parameter setting knob on the front panel.
• Up to 32 settings can be stored as Event memory (in matrix mode) or as Scene memory (in mixer mode*
1
),
which can be recalled by the unit or external connected equipment.
• An RS-232C port permits remote control of the unit using an AMX*
2
or Crestron*3controller, or similar
external equipment.
• A key lock function prevents accidental changes of front panel key or knob operation.
• Volume adjustment, paging initiation, and BGM program selection can be easily remote-controlled. The
optional C-001T module permits the number of control inputs and outputs to be increased.
• Individual zones can be paged by a PABX (extension telephone) with the use of the optional ZP-001T
module.
• A ducker function*
4
permits paging calls to be made without interrupting BGM broadcasts when in matrix
mode.
• Because an auto-mixing function (ducker function*
4
and NOM attenuation function*5) is available when in
mixer mode*1, the input signal volume can be automatically adjusted.
*
1
Current firmware is not equipped with the mixer mode. It will be added when the firmware version is
upgraded in the near future. For details, please contact your nearest TOA dealer.
*
2
AMX is a trademark of AMX Corporation.
*
3
Crestron is a trademark of Crestron Electronics, Inc.
*
4
When a received signal exceeds the gate threshold level, the ducker function automatically attenuates all
other input signals which are lower than that input channel in priority.
*
5
The NOM (Number of Open Microphones) attenuation function automatically adjusts the open microphone's
input channel gain depending on the number of open microphones.

8. OPERATION MODE
Two operation modes are made available to the unit: matrix mode and mixer mode.
Be sure to select one of the two modes by means of the Mode switch on the rear panel before using the unit.
Mixer mode is not used with the current firmware. It will be made usable in the near future when the
firmware version is upgraded.
For details, please contact your nearest TOA dealer.
Important
Be sure to disconnect the power supply plug from the AC outlet when changing the mode.
Since the changes in mode will erase all setting contents, download the set files that need to be stored using
the supplied PC software.
8.1. Matrix Mode
Use the matrix mode when broadcasting BGM or paging calls to zoned areas in such facilities as civic centers,
universities, schools, restaurants, bars, and cruise ships.
Input signals are basically not mixed but distributed in the matrix mode. Multiple audio input signals can be
simultaneously routed to multiple outputs and in addition, paging calls assigned different priority levels can be
initiated during BGM broadcast to each zone.
The ducker function*1also allows paging calls to be made without interrupting BGM broadcasts to each zone.
A maximum of 32 settings related to broadcasts, such as broadcast sound source input channels, interrupt
broadcast output channels, BGM source input channels, and broadcast start methods, can be stored as Event
memory.
8.2. Mixer Mode
This mode is suitable for speech and sound reinforcement applications in the hotel meeting rooms, churches,
and conference rooms.
Input signals are mixed in the mixer mode, and the operator can make fine adjustments to signal mixing in real
time while actually monitoring sound output.
Up to 32 sound adjustments made depending on the usage environment or scene can be stored as Scene
memory and recalled. Further, the input signal sound volume can be automatically adjusted using an automixing function (ducker function*1and NOM attenuation function*2).
*
1
When a received signal exceeds the gate threshold level, the ducker function automatically attenuates all
other input signals which are lower than that input channel in priority.
*
2
The NOM (Number of Open Microphones) attenuation function automatically adjusts the open microphone's
input channel gain depending on the number of open microphones.

9.2. Zone Paging
This section describes the method of initiating zone paging from a PABX (extension telephone) using the ZP001T Zone Paging Module. Note that the operation method differs depending on the ZP-001T's operation
mode setting: paging trunk mode or ring signal mode.
9.2.1. Paging trunk mode
Step 1. Activate the paging trunk from the extension telephone.
Since this method differs depending on the type of exchange, please read the instruction manual for
the extension telephone.
When the paging trunk is activated and the control input terminal is closed, the ZP-001T module
connects the line.
Step 2. Select the output channel.
Press [0] first, followed by the output channel number ([1] – [8] or [9] when selecting all numbers
simultaneously). Pressing the [#] key completes the output channel selection.
Example: To select Outputs 2 and 3, press [0] [2] [3] [#].
To make an all-zone call, press [0] [9] [#].
Step 3. Begin paging when a pre-paging tone is heard from the handset.
The pre-paging tone can be set to be transmitted to all the selected output channels as well.
(The pre-paging tone ON or OFF cannot be individually set for the selected output channels.)
Step 4. Deactivate the paging trunk to terminate paging.
Since this method differs depending on the type of exchange, please read the instruction manual for
the extension telephone.
9.2.2. Ring signal mode
Step 1. Make a call from the extension telephone to the ZP-001T module.
After all call tone sounds twice, the ZP-001T receives the call and a callback tone is heard from the
handset.
Step 2. Select the output channel.
Press [0] first, followed by the output channel number ([1] – [8] or [9] when selecting all numbers
simultaneously). Pressing the [#] key completes the output channel selection.
Example: To select Outputs 2 and 3, press [0] [2] [3] [#].
To make an all-zone call, press [0] [9] [#].
Step 3. Begin paging when a pre-paging tone is heard from the handset.
The pre-paging tone can be set to be transmitted to all the selected output channels as well.
(The pre-paging tone ON or OFF cannot be individually set for the selected output channels.)
Step 4. To terminate paging, press [0] [0] [#] or replace the handset.
If dialing [0] [0] [#]: Pressing a first [0] terminates paging (a DTMF tone for the first [0] is output),
and the ZP-001T disconnects the line after the [#] has been pressed.
If replacing the handset: After a signal tone is transmitted 3 times, the paging is terminated and the
line disconnected.
20
9.3. Activating the Event or Making Paging Calls While Power Is OFF
The 9000 Series amplifiers are designed to initiate paging by way of the ZP-001T module or activate the
Event even while the power is OFF*.
* The state that the front panel-mounted power switch is set to OFF position, while the power is still supplied
to the unit from the AC inlet.
The unit operates as follows when the power is switched OFF:
• Events by control input (including the C-001T module) can be activated, but those using the VOX (VoiceOperated Switch) function cannot be activated.
• The unit returns to Power-OFF state after Event or paging completion.
• Broadcasts can be initiated from the ZP-001T regardless of whether the operation mode is set to Ring Signal
or Paging Trunk.
• Broadcasts cannot be performed for 2 seconds during which the Event is activated and the power amplifier
begins to operate.
• When the power is switched OFF while the Event is being activated by way of the control input, the Event
still left activated is overridden by the above-mentioned Event activations or paging calls initiated from the
ZP-001T regardless of priority settings.
Controls to be performed during power-OFF
The power switch located on the amplifier front panel is a soft-switch, and not a mechanical switch
to be used to turn on or off the power supply's primary side. Therefore, the internal microcomputer
is still operating even if the power switch is set to OFF.
The following controls can be performed when the power is OFF.
• Remote power control by control input
Power can be switched on and off using the external contact.
• Event activation by control input
Turns on the unit's power and activates the assigned Event (set to Trigger) using the external
contact. The unit returns to power-OFF state after Event operation completion.
• Paging by the ZP-001T
Provides the same operation as that which is stated in "Event activation by control input" above.
