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”).
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.
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.

  2. Screw holes

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 SMARTMIXER™, 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 SMARTMIXER™ 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.

Mixer settings

Using with ATDM series DIGITAL SMARTMIXER™
The firmware of the ATDM series DIGITAL SMARTMIXER™ 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 SMARTMIXER™ User Manual.
