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 mode can be selected depending on application for optimum operation.
• Matrix mode is suitable for BGM broadcasts or paging to zoned areas.
• Mixer mode is suitable 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),
which can be recalled by the unit or external connected equipment.
• An RS-232C port permits remote control of the unit using an AMX*
1
or Crestron*2controller, 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.
• Paging calls can be performed by a PABX (extension telephone) with the use of the optional ZP-001T
module.
• A ducker function*
3
permits paging calls to be made without interrupting BGM broadcasts when in matrix
mode.
• Because an auto-mixing function (ducker function*
3
and NOM attenuation function*4) is available when in
mixer mode, the output gain can be automatically adjusted.

The Ducker function automatically attenuates input signals with lower priority when two or more audio
signals are simultaneously received.
*
4
The NOM (Number of Open Microphones) attenuation function automatically adjusts the output channel
gain depending on the number of open microphones.
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.
5.1. General Description
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 (refer to the next page) also 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.

5.2. Glossary
• Ducker function
The Ducker function automatically attenuates input signals with lower priority when two or more audio
signals are simultaneously received. This function cannot be used if any of such received inputs is not set for
the Ducker function.
• VOX (Voice Operated Exchange) function (D-001T only)
This function activates the set Event when an audio signal is input. No Event is activated when no input
signal exists. If the audio signal drops below a preset level after the VOX function begins operation (i.e. after
an audio signal is fed into the module), the set Event is terminated after approximately 5 seconds.
• Event
An "Event" is the unit that defines broadcast pattern and up to 32 Events can be stored.
• Event classification
[ROUTE]
This setting defines which audio input signal is transmitted to which audio output. Multiple outputs can be
selected. Input channels set to priority levels 1 – 7 are for priority broadcasts, while the input channel set to
priority level 8 is for BGM. Set Trigger to "None," "VOX" (D-001T only) or "Control Input" (1 – 12). Selecting
Control Input for Trigger causes the BGM to be activated by pulse trigger, and priority broadcasts to be
operated by level trigger. It is possible to synchronize control inputs and control outputs, with output being
produced as long as the Event is activated.
[BASE]
In this setting, multiple BGM Events are combined into one Base pattern so that they are simultaneously
activated by means of a single activation signal. To use this function, BGM Events (signal routing from input
to output) must be preset in the Route settings.
Up to 4 Route-set BGM Events can be combined into one Base pattern.
Example: Combining Route-set BGM Events Nos. 1, 2 and 3 into one Base pattern, and assigning the
Base pattern to Event No. 4
When BGM Events to which the same output channel is assigned are individually activated, their broadcast
zone depends on the priority setting (first-in-first-out priority, last-in-first-out priority, or mixing) performed in
advance for the Events.
Though BGM Events combined in a BASE pattern are activated simultaneously, the BGM Event with the
smallest input channel number is considered to have been selected first.
Example: Assigning the following two BGM Events to Event No. 3 as Base pattern.
Event 1 = Input 1 Outputs 1 and 2
Event 2 = Input 2 Outputs 2 and 3
In this example, Output 2 is duplicated. However, if system priority is set for "first-in-first-out"
priority, BGM is broadcast to the following zones because Input 1 has a priority:
Event 1 = Input 1 Outputs 1 and 2
Event 2 = Input 2 Output 3
For Trigger, select "None" or "Control Input" (1 – 12). In Base settings, VOX cannot be selected for Trigger
nor can control outputs be synchronized with control inputs. Base settings are not required when only one
BGM program has been set in Route.
• BGM END
Defines the method of stopping BGM broadcasts. Only "Control Input" (1 – 12) can be selected for Trigger.
All current BGM broadcasts are stopped. Control outputs cannot be synchronized with control inputs.
To stop the specified BGM Event set in Route (including the case that the only one Base pattern is
broadcast) when two or more BGM Events are activated, turn off the corresponding input channel at the
unit's front panel.

For details, please contact your nearest TOA dealer.
The ZP-001T module is designed for use with the 9000 Series amplifiers and functions as an interface to
connect the 9000 Series amplifiers to an analog PABX, allowing zone paging to be initiated from the PABX.
There are two operation modes: Ring signal and Paging port modes. Select one of the two modes when using
this module.
The operation method differs depending on the set operation mode. (Refer to p. 22 "Zone Paging.")
[Requirements of the PABX to be connected to the ZP-001T]
• The PABX shall be complaint with TIA/EIA-464-B standard.
• Specifications or conditions required in each of the following modes shall be satisfied:
Note: The ZP-001T may malfunction if the connected PABX does not meet the above requirements.
(A) When using the module in the Paging port mode
• Connection: Line level paging port
• Signaling method: DTMF (The module cannot be operated with dial pulse.)
• Shall provide no-voltage make contact during paging calls.
• Insensitive to whether loop voltage exists or not, and whether polarity of the loop voltage is reversed or
not when a line connection is established.
Note
If the PABX does not meet the above requirements, use the D-001T module and set the trigger to "VOX"
(Voice Operated Exchange) to initiate paging. In this case, the paging output channel cannot be selected,
which differs from the operation by the ZP-001T.
(B) When using the module in the Ring signal mode
• Connection: Analog two-wire extension line, loop start
• Signaling method: DTMF (The module cannot be operated with dial pulse.)
• Reorder tone: 120 IPM (impulses per minute) or less
• Loop voltage: 24 VDC or more* (polarity insensitive)
• Insensitive to whether polarity of the loop voltage is reversed or not at a call from the PABX.*
• Loop voltage supply shall not be cut off from the beginning of a call to the reorder tone out.*
• The state of CPC (Calling Party Controlled) break or "Open Loop Disconnect" shall be reset at the
PABX.*
* Note that there is no need to meet these requirements provided that the ZP-001T's control input terminals
are kept closed. However, noise may be output if the line is physically disconnected during a paging call
because the ZP-001T cannot recognize the line cutoff nor stop output for 30 seconds after paging initiation.

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 port mode or ring signal mode.
In both operation modes, when any of the following situations arises, the ZP-001T will not receive calls from
the PABX or the line will be cut off if the ZP-001T is being engaged in paging call.
• The input channel for the ZP-001T is turned off.
• The input channel for the ZP-001T is muted by way of the control input.
• Emergency-mute (EMG-MUTE) is activated by way of the control input.
9.2.1. Paging port mode
Step 1. Activate the paging port 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 port 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 the pre-paging tone is set to ON (p. 31), begin paging after the tone sounds.
When the selected output channel is being used by other broadcast with higher priority level, a busy
tone is heard from the handset, indicating that paging cannot be performed.
Step 4. Deactivate the paging port 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 a calling 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 the pre-paging tone is set to ON (p. 31), begin paging after the tone sounds.
Paging can be performed within 30 seconds after the call gets through. After 30 seconds have
elapsed, the line is automatically disconnected.
When the selected output channel is being used by other broadcast with higher priority level, a busy
tone is heard from the handset, indicating that paging cannot be performed.
Step 4. To terminate paging, press [0] [0] [#], and then 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 without dial operation: After a signal tone is transmitted about 3 times, the
paging is terminated and the line disconnected.
23
9.3. Releasing Key Lock
The key lock function prevents the front-mounted keys or knobs from being tampered. (Refer to p. 56 "Key
Lock Function setting.")
You can temporarily operate the locked keys by entering a password to unlock them. Operation after
password entry differs depending on the locked keys.
Step 1. Press the locked key.
The password entry screen is displayed with the flashing
indication of the character entry position on the extreme left.
Step 2. Press the Enter key if no password has been set.
If the password has been set, enter it using the Input channel
selection keys.
Entering a character causes the next character entry position
to flash for character entry.
When the entered password is correct, the locked key is
released. If the registered password is comprised of 1 to 3
characters, as soon as entered 1 to 3 characters agree with
them, the locked key is released.
When released keys are those of the type related to input and
output operations, they become temporarily operable, but
revert to the locked state if they are left unused for 1 minute.
When utility-related keys are released, the key lock menu
screen is displayed, clearing the password setting
automatically.
Move to the screen for which you want to make a change.
When wishing to lock the keys using the password even after
the setting has been changed, set the password again. (Refer
to p. 60)
To simultaneously release all locked keys, set the all-key lock
function to OFF on the all-key lock ON/OFF setting screen.
When the power switch is locked, the password entry screen
is not displayed if the power switch is pressed, and so the
power cannot be turned off.
Since the key lock function helps to prevent the front panel
keys or knobs from being tampered, their operation can be
performed by controls through the control input terminals
even if the keys or knobs are locked.

10. EVENT ACTIVATION OR PAGING 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, and 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 (Voice
Operated Exchange) 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 Port.
• 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 an Event is being activated by way of the control input with the power
ON, even if the Event is still left activated, the above-mentioned Events or paging calls from the ZP-001T will
have a priority regardless of priority level.
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 (Trigger-set Event having the input
with Priority 1 – 7) using the external contact. The unit returns to power-OFF state after Event
operation completion.
• Paging by the ZP-001T
Turns on the unit's power. The unit returns to power-OFF state after paging completion.
