IR REMOTE

Volume up and down buttons in local amplified mode.
Mute button during the meeting.
Switch between pickup mode and mixer mode

Pickup Mode: Only pickup sound during the meeting.
Hybrid Mode: Pickup the sound and enable the local amplified mode.

Switch working modes
In conference Pickup Mode, press the speaker button on the remote control, and the indicator light on the lower side of the Speaker CM360 will turn green. During the conference, the ceiling conference microphone only performs conference pickup, and does not perform local sound reinforcement.

In the Hybrid Mode, press the speaker button on the remote control again, and the indicator light on the bottom side of the iSpeaker CM360 will turn blue. During the conference, the ceiling conference microphone will simultaneously perform conference pickup and local sound reinforcement.

Silence the ceiling conference microphone
During the conference, click the mute button, and the indicator light on the lower side of the iSpeaker CM360 will turn red, indicating that the sound pickup has been turned off and the voice of the speakers in the local conference will no longer be picked up. The far-end attendees will not be able to hear the voice of the speakers.

Adjust the volume

During the conference, click the “+” and “-” buttons on the remote control to weaken or enhance the sound volume of the ceiling conference microphone.

CONNECTION

Connect the iSpeaker CM360 to the Dante audio network through a Cat6A network cable. The Ethernet PoE/Ctrl RJ-45 socket is used to both power the iSpeaker CM360 Ceiling microphone via Power over Ethernet and configure it using the Speaker Controller

software.

Note: In your network you can either use a switch that provides PoE or a PoE injector. Use only shielded STP network cables that do not exceed an AWG value of 24.

PC SOUND SETUP

USB DANTE adapter
The example is based INFOBIT iTrans DU-TR-22B, the USB to Dante adapter, which can convert the network audio transmitted by the Dante protocol into a digital audio signal that supports the UAC protocol. Please connect the USB port to your PC.

Select the right AUDIO INPUT and OUTPUT
In the sound card of the PC connected to the Dante audio adapter Trans DU-TR- 22B, it can be seen that all devices have been detected with the GREEN audio indicator bar.

Select the right Speaker and Microphone in meeting software (Zoom as example)

Select the system default speaker and microphone array on the audio settings on the software, and then use the iSpeaker CM360 for audio and video conferencing communication.

Note: On video conferencing software, it is necessary to turn off audio processing functions (background noise reduction, automatic adjustment of microphone volume, etc.) to avoid secondary duplication with the audio processing functions of the Speaker CM360, which can affect the audio quality of the conference during use.

INSTALATION

Possible installation variants

Variant 1 : Installed flush in a dropped/coffered ceiling
Variant 2 : Suspended from the ceiling
Variant 3 : Mounted on the ceiling by VESA mount

Adapting the installation height Observe the following minimum and maximum distances when installing the Speaker СМ360.

Recommended distances for variants 1:
Recommended distances for variants 2 and

The recommended maximum distance from the speaker to the iSpeaker CM360 is 4 to 5 m. The minimum distance from the iSpeaker CM360 to the floor is 2.50 m.

Note: If installation variants 1 would result in a distance greater than the recommended maximum due to the room height, we recommend installation variant 2 or 3.

Variant 1: Installed flush in a dropped/coffered ceiling
The iSpeaker CM360 can be easily installed in a dropped ceiling or coffered ceiling with square ceiling tiles (600 × 600 mm). Angle brackets are available for ceiling tiles with the standard dimensions of 2 ft or 625 mm. When flush mounting, do not install the Speaker CM360 directly next to lights or other electrical devices in the ceiling.

When mounting the unit in the ceiling, always additionally secure the Speaker CM360 against falling:

by using the ceiling suspension safety ropes, which can be attached at the intended mounting points using the included eye bolts.
Hand-tighten the M4x10 eye bolts in the iSpeaker CM360 to avoid damaging the metal housing by screwing them in too deeply.
Make sure that the thread on the eye bolt is fully within the thread at the mounting point.

Note: Installation of variant 1 & 2 require the same attention of these cations.

RECOMMENDED CABLING
Observe the following when connecting and running the cables:

Always run the cables carefully and in a loop shape inside the installation recess.
Make sure not to kink the cables to avoid breaking them or damaging the plugs.

Installing the iSpeaker CM360 in the ceiling (600 x 600 mm grid).

Remove a tile from the ceiling.
Place the iSpeaker CM360 in the frame in the coffered ceiling.
Maintain the distances indicated in the figure.

Variant 1: Installed flush in drywall ceiling

CAUTIONS

Observe the following when install:

The ceiling-mounted conference microphone can be easily installed in suspended soundproof ceilings or drywall ceilings (600 x 600 mm) ceilings.
Be careful not to install ceiling microphones next to light fixtures or other electrical equipment on the ceiling! (Same as guidance in 7.2)

Cut the ceiling according to the size of the ceiling-mounted conference microphone.

Variant 2: Installed by suspending ropes

Same as 7.2

Variant 3: Mounting the iSpeaker CM360 on a VESA mount.
The iMount S200 adapter (available separately) allows you to mount the Speaker CM360 on any 100 x 100 mm or 200 x 200 mm VESA mount.
