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 1 output 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* 2 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.
• Paging calls can be performed by a PABX (extension telephone) with the use of the optional ZP-001T Zone
Paging module.
• With the use of the optional AN-001T Ambient Noise Sensor Input module and AN-9001 Ceiling Mount
Microphone, the amplifier's output volume can be automatically adjusted in response to the change in
ambient noise level.
• Three operation methods are available in Matrix mode; Normal matrix operation, 1-channel output operation,
and 2-channel output operation. Depending on the 9000 Series amplifier model and built-in modules, you
can select either 1-channel output operation method that permits audio signals to be output only at the
output channel 1, or 2-channel operation method that permits BGM broadcasts to be output at the output
channel 1 and priority broadcasts at the output channel 2.
Moreover, with the use of the optional ZP-001T and SS-9001 Speaker Selector, 1-channel or 2-channel
broadcast can be made to 4 zones.
• The optional ZM-9001 Zone Manager adds 6 control inputs, while the optional ZM-9002 Zone Manager adds
4 control inputs and 1 volume control.
• 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.

* 2 Crestron is a trademark of Crestron Electronics, Inc.
* 3 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.
