3. Level Meters/ Control Position Indicator In normal use these audio level meters provide a PPM style visual indication of the left and right audio channels output levels. If however one of the channel on/ solo switches is pressed and held down, then the top meter will indicate a mono’d mix of the selected channel’s stereo output and the bottom meter is used to indicate the pan position of that channel’s output.

There is a 2 rear panel GPI circuit that can be used to cut just the internal loudspeakers. If this 2 GPI circuit is made (i.e. on) then the internal loudspeakers will be cut but the switches internal LED will not be on and this switch will continue to operate a cut on the analogue, AES3 and network outputs.

10. Headphone Socket This 6.35mm (1/4”) tip ring sleeve (TRS) jack socket provides a stereo output for monitoring the mix/ solo buss. Inserting a jack into this socket will cut the internal LS, the analogue and AES3 audio outputs and any network audio outputs affected by the cut circuit. It is suitable of use with headphones with impedances of 100 –...

18. Update Socket The update socket is used by a Glensound authorised engineer in the unlikely event that new internal microprocessor code is required to be installed in the Bella 22. The internal microprocessor is a PIC.
AUDIO BLOCK DIAGRAM Analogue Representation The above diagram is drawn as an analogue audio workflow, however the Bella 32 is a digital device and most functions are actually performed in the digital domain. Page 15 of 27...
NETWORK AUDIO OUTPUTS/ MIX BUSSES There is one main stereo mix buss within the Bella 22. This is referred to as ‘MIX/ SOLO’ or sometimes just ‘MIX’. In simple terms the ‘MIX/ SOLO’ outputs are derived after the front panel Channel On/ Solo buttons.

CONNECTING THE BELLA 32 TO A DANTE® NETWORK The Bella 32 is a network audio devices utilizing the reliable and versatile Dante® audio over IP protocol. Dante® is a proprietary system (although very widely used) the originators of which are Audinate. The information below is only meant as a very basic guide.
The Bella 32 will have been named at the factory during test to allow them to be identified by the Dante controller. The format used for the factory name is: ‘GLENSOUND-BELLA-32-sn-XXX’ The ‘–sn-XXX’ refers to the serial number of the Bella 32 unit which can be found printed on the rear of the unit.
Note if you upload a new DNT file or clear the devices config then the name will change to Bella 32XX-xxXxXx whereby the ‘X’s refer to the devices MAC address. Dante Controller TIP If you have never run Dante controller before then make sure that on the bottom left of the Dante controllers’...
Device Not Showing Up In Dante Controller ® ® If your Dante device does not show up in Dante Controller then the most likely issue is that the device’s IP Address is not appropriate for your network. A) It maybe that the device is set to obtain an IP address automatically using DHCP (this is the default configuration) and your network is setup for fixed IP addresses only and does not have a DHCP server.
AES67 and therefore the Bella 32 can be set to AES67 mode for interaction with other AES67 devices. Please note however that Glensound are relying on Audinate’s AES67 interface and are unfortunately not able to provide full AES67 support for the unit. AES67 support should be sought directly from Audinate.

2. Sending AES67 Audio To transmit AES67 audio to the network a multicast flow must first be setup. This is done by selecting the ‘Create New Multicast Flow’ Icon in the Device View. Tick the AES67 Flow check box, then select up to 4 channels to be included in the flow then click ‘Create’...
UPDATING THE BROOKLYN CHIPSET The Brooklyn module is a device supplied by Audinate that does most of the processing for the actual Dante/ AES67 network audio streams. There is one Brooklyn module in each Bella 32. We supply special code (a .dnt file) that sets up/ initiates the Brooklyn module and makes it work in particular way that is compatible to the Bella 32.
