****** Page 3 ****** 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. MIC IN MIC IN LED LED

****** Page 5 ****** Notices u • 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 tho 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 u Change the height and tilt position according to the environment in which you use the product. MIC position Tilt Tilt up Tilt down Minimum Height 1.2 m 1.7 m (5.5′) Typical Height 1.75 m (5.75′) 22 m (7.2′) Maximum Height 2.3 m (7.5′) 2.7 m 2.3 m 1.76m (6.7b’) Figure A 2.7m 2.2 m 1.7m Figure B Coverage examples • For 3600 coverage, create four hypercardioid (normal) virtual polar patterns at the 00, 900, 1800, 2700 positions. This setting is ideal for providing omnidirectional coverage of four people around a round table (see Figure. A). • For 3000 coverage, create throe cardioid (wide) virtual polar patterns at the 00, 900, 1800 positions. This setting is ideal for covering three people at the end of a rectangular table (see Figure. B). 5

****** Page 6 ****** Using the product with the ATDM-0604 Digital SmartMixer For the firmware of ATDM-0604, please use Verl. I .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 Audi0>Audio System. Activate ‘Virtual Mic Mode”. This will automatically turn the first 4 channels of tho ATDM0604 into virtual polar patterns created from the input of the product. In Setting & Maintenance Operator Access / Operator Page u Once “Virtual Mic Mode” is activated there will be an option to show or hide the “Array Mic Off” button on the operator page. This button allows the operator to mute the mic and turn off 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 u 1. Switch the input of the first 4 channels to Virtual Mic. 2. Adjust tho gain to the required level. (a) • Setting the input gain on one channel will simultaneously change it on all four channels. Low cut, 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. 6 Settings & Maintenance ddu > System Access Access Presets Logging System Info Audio System Gin Delay IJrit Tyt:æ F fip VitLEl Mic McKie @ Settings & Maintenance > > Fader Settings System Settings Operator Access Presets Logging System Info Meeting Room Vuieo Chat (a) Input MIC a Operator Page Restrictions Preset Nurnbe Presets Resunw Fader Posltu:yn Button Array MIC SWItd1 Boud Meeting July —o may AUX MIC 1 Hall
