AN-9001

Thank you for purchasing TOA's Ceiling Mount Microphone. Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

1. GENERAL DESCRIPTION

The AN-9001 is an electret condenser microphone designed for ambient noise detection. It is used in conjunction with the AN-001T Ambient Noise Sensor Input module in the 9000 Series system. It can be mounted in a 1-gang electrical box (American type) in the ceiling or wall.

4. INSTALLATION

Step 1. Install a 1-gang electrical box in a wall or ceiling.

Step 2. Mount the AN-9001's Main unit to the installed electrical box.

Use the 2 screws (No.6-32UNC x 30) supplied with the AN-9001.

Note

The AN-9001 comes with 2 types of machine screws: No.6-32UNC x 30 (unified threads) and M4 x 30 (metric threads). Be sure to use correct ones.

Step 3. Let both detents on the panel's rear into the detent insertion openings of

the Main unit.

Tips

For detent insertion, refer to the following points: (A) Align 2 triangular marks on the panel with the extended line

connecting between Main unit's mounting screws.

(B) Align the panel's center hole with the Main unit's microphone.

Step 4. Rotate the panel clockwise.

The panel locks into place by rotating it about 20° in the "Lock" direction.

3. CONNECTION

The AN-001T and AN-9001 are connected as illustrated below and used to control the speaker sound volume in a room or such closed space.

5. REMOVABLE TERMINAL PLUG CONNECTION

Be sure to use the supplied removable terminal plugs for connections to the removable terminal blocks.

Notes

• Be sure to use shielded cables for audio signal lines.

• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.

Note

Keep the AN-9001 as distant as possible from a sound source (speaker, water supply pipe, or air conditioning). If installed close to a sound source, the AN-9001 could sense it as ambient noise to control the speaker sound volume.
