Armonía Pro Audio Suite; 1.Signal Routing And Dsp Architecture; 2.Purposed Workflow - Powersoft audio Ottocanali Série Guide Rapide

Armonía Pro Audio Suite
Armonía Pro Audio Suite is the default configuring in-
terface that allows system setting and customization of the
Ottocanali DSP+D and DSP+ETH amplifiers.
Armonía can be installed on a PC running Windows
(XP SP3 and higher). Freely download Armonía Pro Audio
Suite from the Armonía forum:
http://www.powersoft-audio.com/en/armonia-forum
Ottocanali DSP amplifers can connect to the PC run-
ning Armonía through a Fast Ethernet connection. In order
to start remote operation, the device must be discovered
and imported into the Armonía Workspace. Click on the
Discover button in the Remote entities windows, or select it
from the Model list and drag it into the Armonía Workspace.
The callback button – located on the front panel of the
amplifier – allows you to highlight the presence of the ampli-
fier into the Armonía Workspace.
Once connected to Armonía Pro Audio Suite a double
click on the amplifier icon in the Workspace will open the
amplifier dashboard. Here it is possible to access and con-
figure all the features of the Ottocanali DSP.

9 : 1.Signal routing and DSP architecture

Signal processing on Powersoft Ottocanali DSP ampli-
fiers accomplishes multiple functions that affect the audio
signal before power amplification; the main adjustements
include gain, polarity, delay, limiting and signal equalization;
some processing are related only to particular stages, such
as limiting and damping control that are implemented on the
output section only, or input priority assignment available in
the input section.
The processing architecture is composed of six sections:
f Input source selection. The input section allows you f
to manage input gain and delay of analog and digital
sources, in order to compensate transmission latency
and levels. Furthermore the Ottocanali DSP+D imple-
ment a backup policy aimed to improve reliability
against signal fault.

f Matrix. The innovative routing engine of Ottocanali f
DSP allows any input to be routed to any output. The
Matrix implements a non-boolean rooting architecture
allowing free channel assignment and level adjust-
ment.
f Advanced processing. This allows you to optimize
f
levels and shape the sound of the input signals. Gain
and polarity adjustment, asymmetric raised-cosine
full parametric filters, delay and mute are available on
each channel routed to the speaker section.
f Speaker equalization. Designed to manage the con-
f
figuration presets for multi-way systems, it implements
FIR and IIR full parametric filters.
f Speaker routing. Once properly grouped, the output f
channels are presented to the matrix as speakers –
a single row representing a speaker (actually group of
ways) – allowing a high grade of granularity in signal
processing.
f Output processing. This allows fine tuning of output
f
signals, aiming to optimize power delivering and loud-
speaker performance. It provides gain and polarity
adjustment, IIR and FIR full parametric filters, delay,
mute, limiting and damping control on each output
channel.

9 : 2.Purposed workflow

Once the loudspeaker layout has been defined, we
suggest a bottom-up configuration procedure that starts
from the configuration of the transducers layout and raises
toward the input selection and the definition of the backup
policy.
Shortly, the main steps to follow are:
1. Set Lo-Z and Hi-Z loads and filters on output channels.
2. Load the loudspeaker presets or manually configure
the loudspeaker layout (grouping output channels,
crossovering, limiting, speaker processing, etc.).
3. Define the routing path and the levels of the signals
from the input channels to the active output channels
(matrix).
4. Select the signal source from the input connections
and define the backup policy (input source selection).
5. Define GPO assignment and alarms thresholds.
