Hanging Microphone Array

ES954

Features

•Ideal, cost-effective solution for huddle rooms, conference rooms and

other meeting spaces.

•Quad-capsule steerable microphone array designed for use with the

ATDM series DIGITAL SMARTMIXER™ and other compatible mixers.

•When controlled by a compatible mixer, provides 360° coverage from

a potentially limitless number (bound by mixer channel count) of virtual

hypercardioid or cardioid pickups that can be steered in 30° increments

to clearly capture every person speaking in a room by using original

synthetic technology (PAT.).

•Mixer-controlled tilt function provides a vertical steering option to

accommodate ceilings of different heights.

•Includes UL 2043 plenum-rated AT8554 Ceiling Mount with RJ45

connectors and push-type wire terminals for simple, secure installation

with seismic cable to secure to a drop ceiling grid.

•Integral, logic-controlled red/green LED ring provides clear indication of

mute status.

•High-output design with low self-noise delivers strong, natural-sounding

vocal reproduction.

•Low-reflective white finish matches ceiling tiles in most environments

•Includes two 46 cm (18") breakout cables: RJ45 (female) to three 3-pin

Euroblock connector (female), RJ45 (female) to 3-pin Euroblock connector

(female) and unterminated LED conductors.

•The 3.0 m (9.8') microphone cable is secured at the celing tile with a

locking grommet for quick microphone height adjustment.

•Audio-Technica's proprietary RFI-shielding technology thoroughly

eliminates radio frequency interference (RFI).

•Requires 11 V to 52 V DC phantom power.

Trademarks

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 ceiling mount 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

appears 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” (bidirectional (figure-of-eight))

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

positioned horizontally at 120°, and MIC4 is “Z” (bidirectional (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, fix the remaining cable to the inside of the ceiling mount using the cable 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 locking grommet 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.

Tilt down 1.7 m (5.6’) 2.2 m (7.2’) 2.7 m (9’)

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).

• For installation of two or more units, we recommend that you install them at a distance of at least

1.7m (5.6’) (for hypercardioid (normal)) so that the coverage ranges of the microphones do not

overlap (see Figure. C).

Using the product with the ATDM series DIGITAL SMARTMIXER™

Use the latest firmware for the ATDM series DIGITAL SMARTMIXERTM.

1. Connect Mic 1-4 of the product to input 1-4 on the ATDM series DIGITAL

SMARTMIXERTM. Launch Web Remote, select “Administrator”, and log in.

• When using two units of the product with ATDM-1012/ATDM-1012DAN at the

same time, connect INPUT 1 to 4 and INPUT 6 to 9.

2. Click the icon ( ) on the top right of the screen then select "System Settings" >

"Audio". Activate "Virtual Mic Mode". This automatically sets the input type of input

channels 1 to 4 of the ATDM series DIGITAL SMARTMIXERTM to "Virtual Mic".

• For input channels other than "Virtual Mic" which is automatically selected by

default, you can also select "Virtual Mic" and make the same settings.

About Operator Access / Operator Page in Settings &

Maintenance

When "Virtual Mic Mode" and "Array Mic Switch" are enabled, an array mic mute

ON/OFF button appears on the operator page. The microphone can be muted on the

operator page.

• This setting is not saved on the device, so rebooting the ATDM series DIGITAL

SMARTMIXERTM restores it to its default position.

Administrator page's input tab on the main screen

1. In the Input tab, check that the input type for input channels 1-4 is set to "Virtual

Mic".

• For input channels other than "Virtual Mic", which is automatically selected by

default, you can also select "Virtual Mic" and make the same settings.

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 Mix and output bus assign can individually be

assigned for each channel.

3. Clicking "Pattern" of the Virtual Mic box (b) opens the settings tab for the directivity

pattern. 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 talker 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 depending on whether the talker is sitting or standing.

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

Using with other compatible mixer

When connecting and using the product with a mixer other than the ATDM series DIGITAL SMARTMIXERTM, directivity can be controlled by adjusting the output of each

channel according to the following mixing matrix.
