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 multi-
channel broadcasts.
4. FEATURES
• Either matrix or mixer*
1
mode 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*
3
controller, 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.

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.

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.

The NOM (Number of Open Microphones) attenuation function automatically adjusts the open microphone's
input channel gain depending on the number of open microphones.
