OVERVIEW
Bella 22 is a 2 buss summing matrix confidence monitor designed for outside
broadcast trucks, studios, theatre and professional audio applications. It is perfect
for easy and cost effective monitoring of multiple network audio sources, ideal for
busy production environments and perfect for monitoring multiple network intercom &
programme feeds.
10 front panel volume controls can each control one or two network audio inputs and
the output of each of these controls can be routed to the left or right mix busses. In
addition to the 20 network audio inputs 2 analogue inputs are also provided for
added versatility.
10 front panel channel on/ solo switches are also provided enabling sources to easily
be turned on/off the loudspeaker monitoring mix, or solod to this mix if required. In
addition to the LS monitoring mix there is a 2nd mix buss that provides a permanently
on mix output fomr the 10 input circuits.
There are 32 network audio outputs in total. 20 off which are the 20 network audio
inputs taken directly after the front panel level controls. 6 are from the mix buss
taken after the solo/ channel on switches and the final 6 are from the 2nd mix buss
that is before the mix/ solo switches.
As well as the network audio outputs 3 line level analogue outputs are provided and
an AES3 output, these follow the switched/ solo mix buss.
The 2 front panel loudspeakers are driven from a DSP to compensate for their size,
the result is surprisingly good, with clear crisp vocals and highly intelligible
reproduction of wider band audio sources. They are driven from a class D amplifier
and have more than sufficient output level for most environments.
The name Bella comes from a common English phrase ‘Listen To Your Mother’
which as a child often means that you’re in trouble!
Dante Alighieri’s mother was Bella Abati.
We therefore hope that if you listen to our Bella 22 it will keep you out of trouble.

Front Panel Features
1. Channel On/ Solo Switch
These 10 round yellow illuminated switches turn the input of the associated
channel on/ off the loudspeaker, analogue, AES3 and mix/ solo network audio
outputs.
Pressing and holding one of these switches will solo its channels output to the
loudspeaker, analogue, AES3 and mix/ solo network audio outputs.
2. Input Source Control
Each of the 10 input channels has 2 network audio sources associated with it.
These appear in Dante controller as the channel number followed by ‘L’ (left)
or ‘R’ (right).
The source input control is a 3 position toggle switch. Moving it left will route
just the left audio input to the channels output routing switch, moving it right
will route just the right audio input to the channels output routing switch and in
its central position both left and right inputs will be sent to the channels output
routing switch.

3. Channel Output Routing
The output routing control is a 3 position toggle switch. It will route the
selected input(s) to the left/ right or both (left & right) mixes. The selected
input (left/ right channel) has a bearing on what is actually routed to the mix
circuits.
The table below shows the relationship between selected inputs to routed
outputs.

4. Input Select Switch
The 10th input channel has the option of taking its left & right audio inputs
either from the Dante/ AES67 audio network OR from a pair of local analogue
audio inputs on the rear of the unit.
5. Dim Switch
When used this illuminated switch will dim both the front panel loudspeakers
and the analogue and AES3 outputs. It will also dim any of the network output
circuits that are after the dim control.
A rear panel GPI circuit also affects the state of this switch. If the rear GPI
circuit is made (i.e. on) then the switches internal LED will illuminate and
pressing the switch will not turn the dim on or off.
