Armonía Pro Audio Suite provides an interface to select
the proper input source and manage input gain and delay of
analog and digital sources, in order to compensate transmis-
sion latency and levels (see FIG.
Furthermore Ottocanali DSP+D amplifiers implement
a backup policy aimed to improve reliability against signal
fault. By assigning a bus priority to the three different input
sources – analog and two Dante streams – per channel, the
system is able to automatically switch to a reliable input con-
nection in case of signal drop or pilot tone mismatch.

4 : 4.Ethernet connections

Ottocanali DSP+D and DSP+ETH amplifiers can be
remotely controlled via an Ethernet connection through a
personal computer and Powersoft Armonía Pro Audio Suite
software. Powersoft recommend the use of Ethernet Cat5
straight through – patch – cables with pin/pair assignments
TIA/EIA-568-B, i.e. T568B, as shown in

4 : 5.Output connections

CLASS 3 WIRING
Output terminals are hazardous: wiring connection
CLASS3
to these terminals require installation by an instruct-
WIRING
ed person and the use of ready made leads. Take care to
secure the output terminal before switching the device on.
Output connectors are Phoenix PC 5/ 8-STF1-7,62
1777891: single-ended wirings for lo-Z loudspeaker and Hi-Z
distributed lines connections are shown in
Bridge-tied connection of lo-Z loudspeaker is supported on
adjacent channel pairs 1-2, 3-4, 5-6 and 7-8; inputs must be
physically paralleled as shown in
Any mixed configuration of low and high impedance
output loads can be realized: in order to set the load
configuration, each channel is provided by four DIP switches
(refer to Panel K, p. 13). Ottocanali Series is configured to
drive Lo-Z loads (Panel K#1) by factory default.

4 : 5.1. Hi-Z 70V/100V operations

Any channel of an Ottocanali Series amplifier can drive
70V/100V (Hi-Z) distributed line of louspeakers. In order to
connect any channel's output to a 70V/100V line, the rear
panel DIP switch corresponding to the channel must be
correctly set as reported in
Powersoft recommends to use the built-in HPF (High
Pass Filter) when the amplifier is set to drive a distributed
line to prevent loudspeaker transformer saturation which
can considerably degrade sound performance. The HPF
can be activated by means of the DIP switch corresponding
to the channel (see Panel K, p.
are available 35 Hz and 70 Hz.

4 : 6.GPO - Alarms

The Ottocanali's GPO – general purpose output – system
implements triggering signals to broadcast alarms.
Ottocanali Series provides a pair of paralleled gen-
eral purpose output connections per channel: one Normally
Open NO and one Normally Closed

The connections are available on the back panel via two
12-pin Phoenix MC 1.5/12-ST-3.81 1803675 connectors for
channels 1-to-4 and 5-to-8: see
These contacts are used to report potentially dangerous
faults or generally unsafe operation conditions by toggling
alarm switches relative to the following events:
f No AC mains (i.e. system shutdown);
f
f Thermal stress: the system temperature reaches 70°C, f
thermal protections are going to be engaged;
f Short circuit in output wiring: either the loudspeaker or f
the line is in short;
f DC presence at the output: a continuously stationary f
signal is present at output terminals.
Ottocanali DSP feature further monitoring on pilot tone
and output load: the GPO monitoring interface in Armonía
Pro Audio Suite software is accessible through
the GPO button located at the top right corner in
the dashboard of the selected Ottocanali DSP
amplifier (refer to Section 9 "Armonía Pro Audio

4 : 6.1. Pilot tone monitoring

Thanks to the built-in DSP, the Ottocanali DSP+D and
DSP+ETH amplifiers implement pilot tone detection and
alert. Detecting and alerting features are available for both
input and output pilot tones on each channel.
The detection of a mismatch in the input pilot tone
12. parameters (frequency and voltage level) can be used to
trigger the backup policy (refer to
Backup policy) and activate an alert through the general
purpose output switch.
The output pilot tone detection relies on an external sig-
nal passing through the amplifier or the internal post DSP
pilot tone generator (see
between the detected signal and the set thresholds triggers
the general purpose output switches.

4 : 6.2. Output load monitoring

Through Armonía Pro Audio Suite software it is pos-
sible to set the thresholds on the load impedance, at given
frequency, that trigger the general purpose output of any
channel of the amplifiers with DSP (see
