Introduction

Thank you for purchasing this product. Before using the product, read through the

user manual to ensure that you will use the product correctly.

Safety precautions

Although this product was designed to be used safely, failing to use it correctly may

result in an accident. To ensure safety, observe all warnings and cautions while

using the product.

Cautions for the product

• Do not subject the product to strong impact to avoid malfunction.

• Do not disassemble, modify or attempt to repair the product.

• Do not handle the product with wet hands to avoid electric shock or injury.

• Do not store the product under direct sunlight, near heating devices or in a hot,

humid or dusty place.

• Do not install the product close to air conditioner or lighting apparatus to prevent

malfunction.

• Do not pull on the product with excessive force nor hang on it after it is installed.

Connection

LED

Connect the output terminals of the microphone to a device that has a microphone

input (balanced input) compatible with a phantom power supply.

The output connector is a Euroblock connector with polarity as shown in the ﬁgure

below.

Use STP cables to connect from the mounting box RJ45 jacks to breakout cables.

Output terminals

The product requires 11V to 52V DC

phantom power for operation.

• Output from the microphone is low impedance (Lo-Z) balanced. The signal ap-

pears across the pair of each output Euroblock connectors on the RJ45 breakout

cables. Audio ground is the shield connection. Output is phased so that positive

acoustic pressure produces positive voltage on the left side of each Euroblock

connector.

• MIC1 is “O” (omnidirectional), MIC2 is “L” (ﬁgure-of-eight) positioned horizontally

at 240°, MIC3 is “R” (ﬁgure-of-eight) positioned horizontally at 120°, and MIC4 is

“Z” (ﬁgure-of-eight) positioned vertically.

LED control

• To control the LED indicator ring, connect the LED Control terminals of the RJ45 breakout cable to the GPIO port of the automatic mixer or other logic device.

• When using the product with a mixer with no GPIO terminal, the LED ring can be kept permanently lit by connecting the black (BK) or violet (VT) wire to the GND terminal.

When the black wire is shorted, the LED ring will be green. When the violet wire is shorted, the LED ring will be red.

Notices

• When installing the product, a hole must be cut into the ceiling tile so the ceiling mount can be ﬁxed in place. Remove the ceiling tile ﬁrst if possible.

• To mount the threaded bushing in a ceiling tile without the isolators:

20.5 mm (0.81") diameter hole is required and the ceiling tile can be up to 22 mm (0.87") thick.

• To mount the threaded bushing with the isolators:

23.5 mm (0.93") hole is required and the ceiling tile can be up to 25 mm (0.98") thick. Place the isolators on either side of the hole to achieve mechanical isolation from the

mounting surface.

Installation

1. Remove the backplate of the ceiling mount and place it against the back of the ceiling tile, allowing the threaded bushing to pass through.

2. Once in place, thread the retaining nut onto the threaded bushing, securing the ceiling mount to the ceiling tile.

3. Connect the microphone cable to the terminal connector on the ceiling mount by pressing down the orange tabs on the terminal strip.

4. Once all connections are made, secure the microphone cable to the PCB using the included wire tie.

5. Adjust the cable to desired microphone height by either feeding or pulling the cable through the ceiling mount.

6. Once the microphone is in the desired position, gently turn the threaded nut clockwise to secure. (Do not over tighten and pull the cable strongly).

7. Coil the excess cable into the ceiling mount and replace the backplate.

Recommended position

Change the height and tilt position according to the environment in which you use

the product.

Coverage examples

• For 360° coverage, create four hypercardioid (normal) virtual polar patterns at the 0°, 90°, 180°, 270°

positions. This setting is ideal for providing omnidirectional coverage of four people around a round

table (see Figure. A).

• For 300° coverage, create three cardioid (wide) virtual polar patterns at the 0°, 90°, 180° positions.

This setting is ideal for covering three people at the end of a rectangular table (see Figure. B).

Using the product with the ATDM-0604 Digital SmartMixer

For the ﬁrmware of ATDM-0604, please use Ver1.1.0 or later.

1. Connect Mic 1-4 of the product to input 1-4 on the ATDM-0604. Launch the ATDM-0604 Web Remote,

select “Administrator”, and log in.

2. Click the icon ( ) on the top right of the screen then select Audio>Audio System. Activate "Virtual Mic

Mode". This will automatically turn the ﬁrst 4 channels of the ATDM-0604 into virtual polar patterns

created from the input of the product.

In Setting & Maintenance Operator Access / Operator Page

Once “Virtual Mic Mode” is activated there will be an option to show or hide the “Array Mic O” button

on the operator page. This button allows the operator to mute the mic and turn o the LED ring from the

operator page for temporary mute.

• This setting is not saved on the device, so rebooting the ATDM-0604 restores it to its default “Mic On”

position.

On the main Administrator page click on the input tab

1. Switch the input of the ﬁrst 4 channels to Virtual Mic.

2. Adjust the gain to the required level. (a)

• Setting the input gain on one channel will simultaneously change it on all four channels. Low cut, EQ,

Smart Mixing and routing can individually be assigned for each channel or “Virtual Mic”.

3. Clicking on the side of the Virtual Mic box (b) opens the settings tab for the directivity lobe.

These can be adjusted between “Normal” (hypercardioid) , “Wide” (cardioid) and "Omni".

4. Clicking the blue button around the circle sets the orientation of each Virtual Mic.

5. Adjust the Virtual Mic. direction towards the source to be picked up.

• The Audio-Technica logo is located on the front of the microphone. The microphone must be oriented

correctly to operate properly.

6. Using the “Tilt” function, you can adjust the directivity on the vertical plane to adjust the angle depend-

ing on whether the talker is sitting or standing.

7. Adjust the individual volume of each Virtual Mic using the Volume Fader.
