OVERVIEW
Bella 32 is a multi 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.
The name Bella 32 refers to 32 network audio inputs, however there are also 2 local
analogue audio inputs on the rear so there are actually 34 front panel monitoring
selection switches.
34 front panel monitoring selection switches are provided enabling sources to easily
be turned on/off the loudspeaker monitoring mix, or solo’d to this mix if required.
Alongside a front panel shaft encoder these 34 front panel switches can also be
used to adjust input gain and pan the output of the channel.
In addition to the LS monitoring mix there are a number of fixed ratio mixers
providing simple but functional circuits between the network inputs and outputs.
There are 32 network audio outputs in total. These are pre-configured to provide all
possible scenarios of monitoring mix outputs (pre LS cut, pre LS Dim, Mono, stereo
etc). In addition to the monitoring mix network outputs there are two network outputs
derived from the two local analogue inputs and also 14 outputs from the internal
mixers.
Three internal 1kHz tone generators and three internal white noise generators
provide the final six network audio outputs. Three of each type are provided to
provide the 3 most commonly used line up levels in the World.
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.

Front Panel Features
1. Channel On/ Solo Switch
These 34 round yellow illuminated switches turn the input of the associated
channel on/ off the loudspeaker mix, 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 and will
also allow gain and pan to be added to the channel using the Master Output &
Function Control.
2. Group Select Switches
Two groups are provided for quick access to regularly monitored sets of audio
sources.
To recall a group just press the GRP 1 or GRP 2 switch and the current
selection of monitoring channels will be replaced by the pre-saved group
selection.
Once finished monitoring a group press the GRP 1 or GRP 2 button again and
the monitoring selection will return to its previous settings.
To add or remove channels on a group press and hold the GRP switch and
while holding the switch select the channel(s) to be added or removed.

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. With the centre highlighted LED indicating that the channel
is panned centre.
4. Left Panel Loudspeaker
This internal loudspeaker is fed audio from the left output of the mix/ solo mix
buss. The front panel overall level control adjusts its volume and the front
panel Cut & Dim switches also affect it.
There is a rear panel GPI that can turn the internal loudspeakers off.
Inserting a headphone jack in the headphone socket also turns the
loudspeaker off.
5. Audio Presence Indicator
The round green LEDs next to the channel on/ solo switches indicate that
incoming audio has been detected on that channel.
It first illuminates dimly when an incoming audio circuit is detected at -40dBFs
or above. It then increases its brightness when the incoming audio level
reaches -20dBFs.
Once illuminated it will stay illuminated for 3 seconds after it detects the input
level to fall below -40dBFs.
The detection level is prior to the channels gain control.
If the Led Flashes this indicates that the input level is either clipping or within
1dB of clipping.
6. Cut LS Switch/ Indicator
When used this illuminated switch will cut both the front panel loudspeakers
and the analogue and AES3 outputs. It will also cut any of the network output
circuits that are after the cut 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 cut on or off.
