Physical Installation

Unpack the BMA 360D and Inspect it carefully. If the shipment shows obvious signs of damage, retain the original box and packing material for inspection by the carrier. Contact the carrier immediately. ClearOne is not responsible for product damage incurred during shipment.

Connect Speakers

• A good time to connect external speakers is before you install the BMA 360D in the ceiling. With speaker wire (not included), connect external speakers to the Phoenix Euroblock connectors.
• The BMA 360D can be operated as 4 independent 15 Watt amplified channels, or in Bridged mode for 2 channel x 30 Watt configuration.

Important: Please note the following PoE requirements:

• When not utilizing the BMA 360D amplifiers, a 36 Watt PoE+ supply may be used.
• When using the BMA 360D amplifiers, a 90 Watt PoE++ supply must be used.
• ClearOne recommends the following PoE power supply kits:
  • ClearOne 36 Watt supply – PN# 910-3200-202
  • ClearOne 90 Watt supply – PN# 910-3200-209

Install the BMA 360D with Seismic Cables

• You can mount the BMA 360D in a suspended ceiling, held in place by the standard T-bar grid, with additional 1/8” diameter seismic cables (not included). For safety, ClearOne recommends attachment at the four points shown.

Connect the BMA 360D to Your Network

• Connect the BMA 360D to your Dante enabled network and PoE power supply. It is recommended to use ClearOne certified PoE injectors in-line with your BMA 360D.

Network Configuration

• The BMA 360D has a single Network connection which serves both IP Configuration and Dante audio connection roles. To perform initial configuration, connect both the BMA 360D and your PC to a DHCP enabled network. You may then discover and configure the BMA 360D using ClearOne’s CONSOLE AI Lite Software. Configuration and control of the BMA 360D is achieved through ClearOne’s CONSOLE AI Lite software.
• Please visit us at https://www.clearone.com/console-ai-lite-configuration-software-0 for CONSOLE AI Lite downloads and details.

PoE Requirements

Power delivery to the BMA 360D is exclusively via PoE injection. If speakers are not connected to the BMA 360D, a 36 Watt PoE+ supply (PoE 802.3AF) can be used. When one or more speakers are connected to the BMA 360D, a PoE++ (802.3bt) 90 Watt injector must be used. Note that the detected available PoE power is denoted in CONSOLE AI Lite in the Admin section. If a 90 Watt supply is detected, the PoE Status will be denoted as “PoE++”

Discovery

CONSOLE AI Lite will discover all ClearOne equipment on the network that can be controlled via CONSOLE AI Lite.

These available devices will be displayed in the Discovered Devices panel:

• If multiple BMA 360Ds are present on the network, you can identify each by clicking on the Locate lightbulb icon.
• This will cause the corresponding physical BMA 360D’s LED bar to flash green until the Locate icon is clicked again, or the Locate Timeout period has expired.

Once connected, navigate to the Device Settings window to perform any modification, or confirm your network settings:

Dante Configuration

• The Dante IP address and Dante MAC address can be found in CONSOLE AI Lite under the Admin>Device Information panel.
• Audio routing to and from the BMA 360D is done via Dante Controller. Be sure that you have the BMA 360D and at least one other Dante enabled device, such as a DSP or Dante Virtual Soundcard attached to your Dante network prior to beginning configuration and routing. Use the Dante Controller software on your computer to verify that your BMA 360D appears on the Dante network’s device list with the Device Name assigned in the Device Settings panel.
• Your BMA 360D is now successfully connected to the Dante network and you can now route audio between your device and other Dante-enabled devices on the same network efficiently and with high audio quality.

Dante Audio Routing

The BMA 360D Dante input and output channel options are designed to meet a variety of conference and voice lift needs. The graphic below outlines audio connection options for both microphone audio to the Dante network, as well as audio from the Dante network delivered to the BMA 360D’s built in 4 channel amplifier.

Use the Dante Controller software to configure audio routing between your device and other Dante-enabled devices on the network. This software is available from the Audinate webpage: www.audinate.com/products/software/dante-controller

For detailed audio control and/or voice lift enabled designs, independent feeds from each individual beam are available via Dante output channels 1-12 from the BMA 360D. These output channels have no gain, mute or volume control processing and are ideal for interfacing the BMA 360D with a Dante enabled audio processor.

For simple room designs, utilize the SmartMix output 13 with integrated AEC, noise cancellation, filtering and zone mixing features. Utilizing the SmartMix microphone output and the built in amplifier channels, a complete system for cloud conferencing can easily be achieved. Below is a routing example using the Dante Virtual Soundcards (DVS) software on a PC for cloud conferencing. This example also utilizes the BMA 360D 4 channel amplifier for in room audio.

Note: That when using the SmartMix output, the AEC reference connection must also be used for proper Acoustic Echo Cancellation performance.

Configuration and Tuning controls in CONSOLE AI Lite

Speaker Bridge Mode and LED Settings

• Speaker Bridge Mode allows the selection of either fully individuated 4 x 15 Watt Amplifier operation or 2 x 30 Watt Bridged mode operation.
• LED Settings allow for customization of LED color, blink and brightness when in Muted or Unmuted states.

SmartMix BMA Gain Setting

You can set the gain level in 3 ways:

• Drag the slider (a).
• Type a value in the text box (b).
• Tap or click the incrementer and decrementer buttons beside the text box (b) to adjust the value.

Note

• Gain controls, Mute and Filtering options only apply to the SmartMix Dante Channel 13 output and do not affect the individuated Dante Beam output Channels 1-12.

SmartMix AEC and NLP

• AEC (Acoustic Echo Cancellation) reduces or removes acoustical echo from an input signal to improve audio clarity.

The AEC function provides full bandwidth (20Hz to 22kHz) echo filtering of the microphone signal. It uses a reference source (Dante input 5) which should include a mix of all far end participant receive audio that is being delivered to the room speakers. Non-linear Processing (NLP) increases the power of echo cancellation for challenging acoustical environments.

You can select the following:

• Whether or not you want to use AEC. Tap or click the checkbox (a) if you want to use AEC.
• The level of aggressiveness. Tap or click the appropriate radio button (b).

Note

• AEC processing is only available for the SmartMix Dante output channel 13 from the BMA 360D.

SmartMix Noise Cancellation

Noise Cancellation removes ambient (background) noise from an input signal, with no noticeable degradation in signal quality. To enable noise cancellation, tap or click the Enable Noise Canceller check box. You can change the cancellation depth with any of the following methods:

• Drag the slider (a).
• Type a value in the text box (b).
• Tap or click the incrementer and decrementer buttons beside the text box to set the value (c).

Note

• Noise Cancellation processing is only available for the SmartMix Dante output channel 13 from the BMA 360D.

SmartMix Microphone and Speaker Filters

Filters enable you to shape the audio signals from microphone inputs channels and to speaker output channels for improved audio quality. You can add up to four filters to a microphone or speaker channel. Available filter types include the following:

Filter Type Description

• All Pass Frequency range is 20Hz to 20kHz. All pass changes the phase of the audio signal at the set frequency.
• High Pass Selectable frequency cutoff is 20Hz to 20kHz. Rolloff is 12dB/octave. Level is fixed at 0dB.
• Low Pass Selectable frequency cutoff is 20Hz to 20kHz. Rolloff is 12dB/octave. Level is fixed at 0dB.
• Notch Center frequency range is 20Hz to 20kHz. Bandwidth is from 0.05 to 5.00 octaves in 0.01 octave increments. Level is fixed at -80dB.
• Parametric Equalizer (PEQ) Center frequency range is 20Hz to 20kHz in 0.01Hz increments. Bandwidth is 0.05 to 5 octaves in 0.01 octave increments. Level range is -15 to +15dB in 0.5dB increments.

SmartMix Automatic Level Control (ALC)

• ALC utilizes a level normalization algorithm to keep soft and loud local participants at a consistent level.

SmartMix AEC Reference

The BMA 360D Dante input Channel 5 delivers far-end receive audio to the built-in Acoustic Echo Canceller (AEC) so that echo can be removed from the microphone audio.
The Linked Channel drop down allows for the AEC Reference levels, filtering and Mute status to follow one of the Amplifier channels. When linked, the volume slider (b) will be disabled.

• The volume slider (b) allows for control of the AEC reference gain.
• Metered dB level of the AEC Reference signal ( c) Post Gain.
