Notes on use
Do not swing the microphone by holding the cable or pull on the cable forcefully. Doing so may cause disconnection or damage. Do not install near air conditioners or lighting fixtures, as doing so may cause malfunction. Do not wind the cable around the rack or allow the cable to become pinched.

Operation
The microphone is muted/unmuted using a talk switch on the product. The talk indicator lamp also lights in conjunction with talk switch operation.
The microphone always stays on. The talk indicator lamp lights in conjunction with the operation of the talk switches, and the operation information is transmitted to the external control device via the CLOSURE terminal. The external control device controls muting/unmuting.

The product requires 20 to 52 V DC phantom power supply for operation. The output connectors are Euroblock connectors with polarity as shown in the "Wiring table" (p. 8).
Wiring table
Microphone output is low impedance (Lo-Z), balanced type. Signals are output on each pair of Euroblock connectors on the RJ45 breakout cables. Audio grounding is achieved with a shielded connection. The output of each Euroblock connector is as shown in the pin assignment. MIC 1 is "O" (omnidirectional) and MIC 2 is "L" (bidirectional), with both positioned at 240° horizontally. MIC 3 is "R" (bidirectional), and is positioned at 120° horizontally. These are combined to create a directional pattern in any desired direction. The pin number sequence of the output terminals is as follows.

Installation procedure
How to mount the product
The product is mounted by drilling a hole in a table and using the included table mount adapter to secure it to the table.
1 Decide where you want to mount the product and drill a hole in the table at that location.
A 30 mm (1.2") diameter hole is required. Also, the maximum thickness of the table is 30 mm (1.2").
30 mm
2 Remove the cable fixing screws on the bottom of the microphone.
Retain and do not lose the removed cable fixing screws. You will need them if you ever decide to use the product without attaching it to a table.
3 Attach the table mount adapter to the bottom of the microphone.
Attach the table mount adapter with the included table mount adapter mounting screws. Attach the table mount adapter so that the cable runs alongside the table mount adapter. Do not pass the cable through the interior of the table mount adapter.

Installation procedure
4 Pass the end of the cable down through the hole in the table and then pass the table mount adapter through the hole. Next, pass the rubber isolator up around the table mount adapter and insert it into the hole in the table, making sure that the cable runs along the indentation on the rubber isolator.

Mounting without using the table mount adapter
When mounted and installed without using the table mount adapter and without drilling a 30 mm (1.2") diameter hole in the table, the microphone is secured using the two screw holes shown in the figure below.
Remove the cable fixing screws on the bottom of the microphone and use commercially available screws. Screw size should be M3 P=0.5 and screw length should be no more than 7 mm (0.28") from the bottom of the head to the tip of the screw.

Sound pickup coverage
For 360° coverage
Creates four hypercardioid (Normal) virtual directional patterns at 0°, 90°, 180°, and 270°. This setting is ideal for omnidirectional recording of a conversation between four people seated at a round table.
When connecting to the ATDM series DIGITAL SMARTMIXERTM, the input type for input channels 1-3 is set to "Virtual Mic" by default, however, if the sound pickup coverage is to be divided into four or more sections as shown in this example, set the input type to "Virtual Mic" for input channels 4 and onward. For detailed operating instructions, refer to the ATDM series DIGITAL SMARTMIXERTM user manual.
For 300° coverage
Creates three cardioid (Wide) virtual directional patterns at 0°, 90°, and 180°. This setting is ideal for picking up a conversation between three people seated at the end of a table.
When installing 2 or more of this product
We recommend that the microphones be placed at least 1.7 m (5.6') (for the hypercardioid (Normal) setting) apart so that the coverages of each microphone do not overlap.
1.7 m

Mixer settings
Using with ATDM series DIGITAL SMARTMIXERTM
The firmware of the ATDM series DIGITAL SMARTMIXERTM should be up-to-date before use.
1 Start the Web Remote, select "Administrator" and log in.

2 For subsequent settings and operations, refer to the ATDM series DIGITAL SMARTMIXERTM User Manual.

When using other mixers
When using the product with a mixer other than the ATDM series DIGITAL SMARTMIXERTM, you can adjust the output of each channel according to the following mixing matrix to control the directionality.
