GPIO
This 9 pin D plug provides access to the GPIO (General Purpose Inputs &
Outputs) circuits. These are useful for connecting to external devices such as
red light systems.
Please see the wiring section of tis handbook for more details.

AES3 Output
The AES3 output is an output of the mix/ solo buss’ left & right channels. This
circuit’s sample frequency is 48kHz and it driven as a direct output from the
internal DSP.
17.
Local Audio Inputs
The local audio input XLRs are both balanced analogue with a line up of
0dBu. They are electronically balanced and their inputs can be wired
unbalanced.
Their audio input is fed into the mix bu
sses via input channel’s 10 ‘Dante/
Local’ toggle switch. The switch needs to be in the ‘Local’ position for the
outputs of these audio inputs to be fed into the mix buss.
18.
SFP Ethernet Slots
These 2 SFP Ethernet slots can accept most standard SFP (GBIC) modules.
Only one port is required to be connected to your network to correctly pass
Dante®/ AES67 network audio, however both the primary and secondary
ports can be used if a redundant network topology is in use.
Both ports are gigabit Ethernet and the LEDs flash to indicate data is being
correctly communicated with a switch.
19.
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.
20.
Analogue Output XLRs
3 analogue output XLRs are provided, marked as ‘Mix Out’, ‘R’ (right), ‘L’ (left)
& ‘Mono’. These are line level electronically balanced analogue audio circuits
with a nominal lineup level of 0dBu. Being electronically balanced they can be
wired unbalanced if required.
The audio being routed to these circuits is the output of the Mix/ Solo mix
buss and they are affected by the Cut and Dim LS circuits and the overall
level control.
