3. GENERAL DESCRIPTION

TOA's 9000 Series Amplifiers are Matrix Mixers designed to be used in conjunction with optional modules and can be configured for up to 8 inputs and 8 outputs. Usable modules include the following 9000 series plug-in modules: D-001T and D-001R (2-channel input), T-001T (Audio output expansion), C-001T (Control I/O expansion), ZP-001T (Zone paging), and AN-001T (Ambient noise sensor), as well as 900 series input modules. The most appropriate modules can be selected depending on applications.

By changing operation mode, the 9000 Series Amplifier 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 amplifier*. Further, settings data can be stored inside the amplifier and called up using the keys on the front panel.

The M-9000 is a Matrix Mixer Pre-Amplifier featuring the above matrix mixer function. Besides the M-9000's matrix mixer function, the following A-9000 Series Amplifiers come with power amplifiers, out of which A-9060DH, A-9120DH, and A-9120DL can perform 2-channel or stereo broadcast in stand-alone operation.

A-9060DH: 60 W (70 V output) x 2 A-9120DH: 120 W (70 V output) x 2 A-9120DL: 120 W (4 Ω output) x 2 A-9060S: 60 W x 1 A-9120S: 120 W x 1 A-9240SH: 240 W (70 V output) x 1

* You can make setting data easily on the PC by using the Programming Software or the Excel file prepared

as a utility tool for data setup; both are contained in the supplied CD-ROM. For data setup on the Programming Software and the Excel sheets, refer to the instruction manuals of "PROGRAMMING SOFTWARE" and "EASY DATA SETUP USING EXCEL SHEETS" also contained in the CD-ROM.

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*

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 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*

permits paging calls to be made without interrupting BGM broadcasts when in matrix

mode.

• Because an auto-mixing function (ducker function*

and NOM attenuation function*4) is available when in

mixer mode, the output gain can be automatically adjusted.

AMX is a trademark of AMX Corporation.

Crestron is a trademark of Crestron Electronics, Inc.

The Ducker function automatically attenuates input signals with lower priority when two or more audio signals are simultaneously received.

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

5. INSTALLATION PRECAUTIONS

• Keep the 9000 Series Amplifiers except the M-9000 over 10 cm away from objects that may obstruct air flow to prevent the unit's internal temperature rise.

7.2.3. ZP-001T (Zone Paging Module)

3. Telephone input terminal [TEL IN] (Modular jack)

Interface connector for an analog PABX. Connect a PABX to this terminal when using the module in the ring signal mode.

4. Paging input terminal [PAGING IN]

4-pin removable terminal block, 2 pins are used for this input. This terminal is used to connect a PABX in the paging port mode.

5. Control input terminal [CONTACT IN]

4-pin removable terminal block, 2 pins are used for this input. Connect the control output from a PABX to this terminal.

6. Control output terminals [CTRL OUT 1 G, 2 G, 3 G, 4 G]

4-pin removable terminal blocks, control output terminals. Note: These terminals are not used in the Mixer mode.

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. Only one ZP-001T module can be used per 9000 Series amplifier.

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. 32 "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/R 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 V DC or more (polarity insensitive), which should be supplied from the PABX.

• 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.

The C-001T module is designed for use with the 9000 Series amplifiers and can provide up to 8 channels each of input and output expansion. Since the main unit has 4 fixed inputs and outputs each, the control input and output can be expanded to up to 12 channels each when the C-001T module is used.

7.2.5. AN-001T (Ambient Noise Sensor Input Module)

9. Monaural input terminals [1, 2]

Electronically-balanced 3P removable terminal blocks. Input level: –60 dB to –10 dB selectable. Input impedance is 10 kΩ when the phantom power is OFF, and 3 kΩ when ON.

The AN-001T module is designed for use with the 9000 Series amplifiers and automatically adjusts the amplifier's output volume in response to the change in ambient noise level. Maximum 2 AN-001T modules (4 channels in total) can be used per 9000 Series amplifier. It can handle signals from microphone level (–60 dB) to line level (–10 dB) by controlling the gain in 9 steps. Phantom power (+24 V) can be supplied to a condenser microphone. The AN-001T's inputs are for detecting ambient noise level and cannot be used as normal audio inputs. Ambient noise fed to the inputs can be monitored when the monitor function is set to ON in the Input setting flow.

Note

In designing the layout of the AN-9001, pay particular attention to the following points so that the AN-9001 and AN-001T in combination can function effectively.

• Position the AN-9001 fully away from the speaker to be used for zone announcement. Doing otherwise may cause the AN-9001 to detect the speaker sound as noise, failing to keep the optimum sound level.

• Do not position the AN-9001 near the equipment that constantly generates loud noise. If positioned, the AN9001 will respond to such loud noise, failing to respond to the change in ambient noise level.

Mode switch

8.1. General Description

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. Storing the set parameters in the Scene memory permits them to be recalled whenever needed. Unless otherwise stored, the changed parameters are abandoned when the AC power supply is shut off. 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* and NOM attenuation function*).

* Refer to p. 28 "Glossary."

8.2. Glossary

• ANC (Ambient Noise Control) function (AN-001T only)

The ANC function automatically adjusts the amplifier's output volume in response to the change in ambient noise level. The output volume changes as the ambient noise level goes above or below the set reference level.

• 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 and D-001R only)

This function initiates the set paging when an audio signal is input. No paging is initiated 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 paging is terminated after approximately 5 seconds.

• NOM (Number of Open Microphones) attenuation function

The NOM attenuation function automatically adjusts an output gain depending on the number of open microphones. The output gain is attenuated by the value set on the Utility setting screen (p. 58-C3) each time the number of open microphones doubles. This function helps to prevent feedback.

• Gate function

The gate function allows the input signal to be passed, attenuated or cut depending on its signal level. The gate allows the signal to pass when open with the signal level over the set value, and to be attenuated or cut when closed with the signal level below the set value. The gate's open/close operations control the Ducker function and the NOM attenuation function.

• Scene

A "Scene" is the unit that defines broadcast pattern and up to 32 types of Scenes can be saved as Scene memory. Input and output parameters that have been set can be saved in the Scene memory and recalled as needed. (Refer to p. 85 "Memory setting items.")

9. OPERATION

To operate the unit, you can use the saved Scene settings, or adjust the sound volume and tone or turn the input/output channels on or off through the front key operation or by way of remote control with the default settings as they are.
