Ottocanali Series Quick Guide

2

2 : 1.Welcome

Congratulations on buying a Powersoft Ottocanali Series

amplier!

We know you are eager to use your new Ottocanali amplier,
but please take a moment to read this quick guide and the safety
instructions. In case you have any questions, please do not hesi­tate to contact your dealer or Powersoft.

The Ottocanali Series is specically designed for installation
applications. Ottocanali Series offers smaller dimensions, lighter
weight and the traditionally amazing sound quality and reliability
of all Powersoft products.

The built in PFC (Power Factor Correction) allows awless
worldwide operation with any AC mains voltage, from 100 to 240V;
patented SRM (Smart Rails Management) technology allows
to maximize the efciency of the system and drastically reduce
power consumption at any load and usage condition. This system
automatically alters the rails working voltage according to the in­staneous power requirements of the system. A low output power
requires a lower rails voltage which in turn yields lower power
consumption while at the same time guaranteeing lightning fast
switching to full rails voltage when the system requires full power.

Ottocanali Series implements redundant power supplies for
maximum reliability even in case of system fault. In case of da­mages in one power supply, the other one is capable to maintain
the system up, guaranteeing non-stop functionality even in harsh
conditions.

Ottocanali Series is designed to work with lo-Z (from 2 �) and

with 70V/100V distributed lines: any mixed conguration of low
and high impedance output loads can be realized, making the
Ottocanali Series suitable to all application in installed sound
reinforcement systems.

Ottocanali Series encompasses three models:

 Ottocanali 12K4 delivering up to 1500 W per channel at 4�

 Ottocanali 8K4 delivering up to 1000 W per channel at 4�

 Ottocanali 4K4 delivering up to 500 W per channel at 4�

Each model is available in three versions: normal, with DSP plus

Dante™ and with DSP plus Ethernet connectivity.

2 : 2.Unpacking & checking for shipping damage

Installation

3

3 : 1.Location

Ottocanali Series ampliers are meant to be installed into rack.
In order to limit the risk of mechanical damages, the ampliers must
be xed to the rack using both frontal and rear mounting brackets.
We recommends to use eight M6 or 12-24 UNC-2B screws for
threaded holes or cage nuts.

The AC mains connection of the units should be connected to
a proper circuit breaker (refer to §3 : 4.AC ma ins supp ly for more
details).

Install this amplier as far as possible from radio tuners and TV
sets. An amplier installed in close proximity of such equipment
may experience noise or generic performance degradation.
Placing and using the amplier for long periods of time on heat
generating sources will affect its performance. Avoid placing the
amplier on heat generating sources.

This device must be powered exclusively by
earth connected mains sockets in electrical

networks compliant to the IEC 364 or similar rules.

Powersoft suggests to plug

the Ottocanali to a 32 A rating,

C or D curve, 10 kA sectioning breaker.

AC mains connections must be performed

only by professional or qualified personnel

according to local electrical authorities guidelines.

3 : 2.Cooling

Install the amplier in a well-ventilated location: the ventilation
openings must not be impeded by any item such as newspapers,
tablecloths, curtains, etc; keep a distance of at least 50 cm from
the front and rear ventilation openings of the amplier.

All Powersoft ampliers implement a forced-air cooling system
to maintain low and constant operating temperatures. Drawn by
the internal fans, air enters from the front panel and is forced over
all components, exiting at the back of the amplier.

The amplier’s cooling system features “intelligent” variable­speed DC fans which are controlled by the heatsink temperature
sensing circuits: the fans speed will increase only when the tempe­rature detected by the sensors rises over carefully predetermined
values. This ensures that fan noise and internal dust accumulation
are kept to a strict minimum.

Should however the amplier be subject to an extreme thermal
load, the fan will force a very large volume of air through the heat
sink. In the extremely rare event that the amplier should dan­gerously overheat, sensing circuits shut down all channels until
the amplier cools down to a safe operating temperature. Normal
operation is resumed automatically without the need for user
intervention.

Ottocanali Series ampliers can be stacked one on top of the
other due to the efcient cooling system they are equipped with.

There is however a safety limit to be observed: in case a rack
with closed back panels is used, leave one rack unit empty every four
installed ampliers to guarantee adequate air ow (see Panel N, p.

14).

3 : 3.Cleaning

Always use a dry cloth for cleaning the chassis and the front
panel. Air lter cleaning should be scheduled according to the
dust levels in the amplier’s operating environment.

Disconnect the AC mains source before

attempting to clean any part of the amplifier

In order to clean the vent lters you need to remove the front
cover: never attempt to open any other part of the unit.

1. Firmly grip the outermost silver colored panel and pull outwards
at an angle, as if opening a door (seePanel B, p. 7).

2. Carefully slide the metal panel away from the chassis. When
the front panel is removed, the air lter (looking like a shiny
black plastic sponge) will be exposed.

You may use compressed air to remove the dust from lters, or
wash it with clean water: in the latter case ensure that the lter is
dry before reassembly.

3 : 4.AC mains supply

Ottocanali Series ampliers implement two universal redun­dant switching mode power supplies operating in the range from
100 V

AC

up to 240 VAC ±10%.

AC mains connection is in the rear panel through the IEC C20 inlet
with power switch: the approved power cord is provided (see FIG. 1).

FIG. 1: AC mains connection.

3 : 5.Energy save

Energy save capabilities can be activated for each channel
pair. Four DIP switches are located on the left hand side of the
front panel (see Panel C, p. 8 and Panel E, p. 10): in order to
activate the Energy save mode for channel pair set the switches in
the bottom position.

When the Energy save mode is activate on a channel pair, the
Ottocanali enters a low power consumption idle state when no
signal activity is detected for more than 4 seconds. Normal ope­ration is resumed in a matter of milliseconds when an incoming
signal is detected on the channel pair.

TAB . 1 shows the power consumption in idle mode for non-

DSP amplifers, when the Energy save is either enabled or disabled
on all channels.

TAB. 1: Idle consumption.

Note: in caswe a pilot tone is used for checking system integrity
and line faults, the Ottocanali amplier would continuously detects
a stationary signal that prevents the the idle mode. In this condi­tion the Energy save will never activate.

3 : 6.Remote ON/OFF (standby mode)

Remote ON/OFF is available throurgh the proper terminals in

Connections

4

Make sure the power switch is off before attempting to make

any input or output connections.

By using good quality input and speaker cables, the likelihood

of erratic signal behavior is reduced to a minimum. Whether you
make them or buy them, look for good quality wires, connectors
and soldering techniques.

4 : 1.Signal grounding

There is no ground switch or terminal on the Ottocanali Series

ampliers. All shield terminals of input connections are directly
connected to the chassis. This means that the unit’s signal groun­ding system is automatic. In order to limit hum and/or interference
entering the signal path, use balanced input connections.

In the interests of safety, the unit MUST always operate with

electrical safety earth connected to the chassis via the dedicated
Protective Earth

wire.

4 : 2.Analog audio input connections

Ottocanali Series ampliers implements two analog input con-

nections per channel: LINE and AUX input. Input selection is made
via software or through the AUX SEL. IN switch (see §4 : 2.1. AUX

SEL. IN: Analog input selection).

Analog input is provided by means of four Phoenix MC 1,5/12-

ST-3,81 1803675 connectors (see Panel D, p. 8 and Panel F,

p. 10), two for LINE input (channels 1-to-4 and 5-to-8) and two

dedicated to the AUX input (channels 1-to-4 and 5-to-8). Signal
polarity of analog input connections is shown in Panel G, p. 12.

4 : 2.1. AUX SEL. IN: Analog input selection

Ottocanali Series ampliers can switch from analog LINE in-

puts to AUX inputs when a constant voltage in the 12 V

DC

to 30 VDC
range is applied to the AUX SEL. IN connector (see Panel D, p.

8 and Panel F, p. 10). When this voltage is removed from

the AUX SEL. IN, the unit switches back from AUX inputs to LINE
inputs.

4 : 2.2. PWS OUT: Built-in auxiliary power supply

The PWS OUT connector provides a 24VDC – symmetrical with
respect to ground (0.2 A max) – when enabled by the toggle switch
on the front panel (see Panel C, Panel D, p. 8 and Panel E,

Panel F, p. 10).

By wiring the PWS OUT connector to the AUX SEL. IN as
shown in FIG. 3, the front panel PWS OUT switch is enabled to
toggle between analog LINE inputs and AUX inputs: this provides
an additional manual procedure to switch from analog LINE to
AUX and vice versa.

4 : 3.Digital audio input connections

Digital input is supported via Dante™ standard protocols in

Dante equipped devices.

In Ottocanali DSP+D ampliers, Dante connectivity is suppor­ted via two Ethernet ports located on the rightmost side of the
rear panels (see Panel F, p. 10). Fast Ethernet (IEEE 802.3u,
100 Mbit/s) and Gigabit Ethernet (IEEE 802.3ab, 1Gbit/s) network
protocols are supported; Cat5e or Cat6 standard UTP twisted pair
cables shall be used for connections up to 100 meters (328 ft).

Ethernet cabling must comply to TIA/EIA-568-B and adopt the
T568B scheme pinout, as shown in Panel L, p. 14.

4 : 3.1. Input selection and Backup policy

In Ottocanali DSP+D ampliers it is possible to select among
three input signal sources per channel: analog (either LINE or AUX)
and two Dante streams (streams 1-to-8 and 9-to-16).

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 transmission latency and
levels (see FIG. 4).

Furthermore Ottocanali DSP+D ampliers 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 connection in case of signal drop or pilot
tone mismatch.

Ottocanali DSP+D ampliers 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 Panel L, p. 14.

4 : 5.Output connections

CLASS3

CLASS 3 WIRING

Output terminals are hazardous: wiring connection to the-

se terminals require installation by an instructed 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 Panel H, p. 12. 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 Panel J, p. 12.

Any mixed conguration of low and high impedance output
loads can be realized: in order to set the load conguration, each
channel is provided by four DIP switches (refer to Panel K, p.

13). Ottocanali Series is congured 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 amplier 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

Panel K, p. 13.

Powersoft recommends to use the built-in HPF (High Pass
Filter) when the amplier 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.

13): two cutting frequency 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 general purpose
output connections per channel: one Normally Open

NO and

one Normally Closed

NC.

The connections are available on the back panel via two 12­pin Phoenix MC 1.5/12-ST-3.81 1803675 connectors for channels
1-to-4 and 5-to-8: see Panel I, p. 12 for wirings.

These contacts are used to report potentially dangerous
faults or generally unsafe operation conditions by toggling alarm
switches relative to the following events:

 No AC mains (i.e. system shutdown);

 Thermal stress: the system temperature reaches 70°C, ther-

mal protections are going to be engaged;

 Short circuit in output wiring: either the loudspeaker or the

line is in short;

 DC presence at the output: a continuously stationary 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 amplier (refer to Section 9

“Armonía Pro Audio Suite”).

4 : 6.1. Pilot tone monitoring

Thanks to the built-in DSP, the Ottocanali DSP+D ampliers
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 parameters
(frequency and voltage level) can be used to trigger the backup
policy (refer to §4 : 3.1. Input selection and Backup policy) and
activate an alert through the general purpose output switch.

The output pilot tone detection relies on an external signal
passing through the amplier or the internal post DSP pilot tone
generator (see FIG. 4); in both cases any mismatch 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 possible to set
the thresholds on the load impedance, at given frequency, that
trigger the general purpose output of any channel of the ampliers
with DSP (see FIG. 5).

TAB. 2: Front panel LEDs chart.

The row of potentiometers in the front panel behave differently

on non-DSP ampliers and Ottocanali DSP+D ampliers:

 In non-DSP Ottocanali ampliers, the potentiometers act

as trimmers on the input level (see Panel C, p. 8): the
input signal is muted when the trimmer is completely turned
counterclockwise; on the other hand, no attenuation is ap­plied when the trimmer is completely turned clockwise.

 In Ottocanali DSP the potentiometers attenuate the speakers

gain (see Panel E, p. 10): they modify the overall gain ap­plied to the group of ways belonging to the selected speaker.
The amount of gain attenuation (External gain) is shown in
Armonía Pro Audio Suite.

Firmware updates for Ottocanali DSP+D can be loa­ded via the front USB port. Updated releases of the Otto­canali DSP rmware are available on the Armonía forum
(http://www.powersoft-audio.com/en/armonia-forum).

The package contains the rmware update le whose name is
in the form:

update-version#-model.bin

(e.g. update-1.6.0.10-8ch.bin): store the rmware update le into a

USB storage device and follow these instructions:

1. Switch the amplier on and wait for the completion of the
boot sequence.

2. Plug the USB storage device with the rmware update le to
the USB port in the front panel of the amplier.

3. Keep pressed the FW UPDATE pushbutton until thefront
LED bars start blinking.

4. The update process lasts in 3-5 minutes. At the end the
system reboots and it is possible to extract theUSB storage
device.

Networking

8

Ottocanali DSP+D ampliers support linear daisy-chain, star
and loop network topologies; in a daisy-chained network the PC
with Armonía Pro Audio Suite must always be at one end of the
chain.

Be aware that daisy-chaining does not guarantee reliability
in production environment, since any fault may yield to network
sectioning and lost of system control.

When efciency and reliability are paramount, a redundant net­work topology is advisable. In order to exploit the Dante features,
star and open daisy-chain network topology are allowed.

8 : 1.IP addressing

Factory default network settings are DHCP/AutoIP,
inorder for the amplier platform to self-congure when connected
to an existing LAN or PC. Fixed IP policy can also be adopted and
congured through Armonía Pro Audio Suite.

If a DHCP server is not active within the network, the ampli­er platform initiates a stateless address auto-conguration (i.e.
Zero-conguration networking methodology – Zeroconf): it self
assigns a local numeric network address (of the type 169.254.x.y
– 172.31.*.* for the secondary network ifpresent– with a subnet
mask 255.255.0.0) and automatically distributes and resolves the
hostnames of networked devices. For setting a static IP address
please refer to the Armonía Pro Audio Suite user guide.

8 : 1.1. IP Addressing troubleshooting

When connecting the Ottocanali DSP+D to a network envi­ronment it may happen that Armonía Pro Audio Suite does not
discover or import the amplier.

Usually this is a problem of IP addressing: both Armonia and
the Ottocanali DSP must belong to the same subnet. If a DHCP
server is present on the network and a Ottocanali DSP amplier is
in AUTO IP, networking may become unstable.

As a rule of thumb, turn the DHCP server

on before connecting the amplifiers.

IP addressing of an Ottocanali DSP+D amplier is established
during the bootstrap: when the Ottocanali DSP amplier discovers
a DHCP server on the network during the startup, it negotiates
the networking parameters. If the Ottocanali DSP does not reveal
a DHCP server on the network during the startup it set itself in
AUTO IP mode.

8 : 2.Dante™ networking

The Dante equiped models of Ottocanali DSP+D amplier
support Dante redundant networking via the two Rj45 ports on
the rear panel:

 Primary/ETH1 is the Primary network port;

 Secondary/ETH2 is the Secondary network port.

Dante connectivity is always supported on the Primary/ETH1
Gigabit Ethernet port; the Secondary/ETH2 Gigabit Ethernet port
offers continuity of operation when a parallel redundant network
is established.

In order to implement a Dante network, a computer running
Dante Controller have to be used. Dante Controller is a software
application that manages devices on the network. Ottocanali
DSP+D ampliers are automatically discovered and displayed in
Dante Controller with the default identier

MODELNAME-SERIAL

(e.g.

8K4-71520).

Dante networks will almost always require at least one network
switch. Redundant infrastructures may require multiple switches.
For maximum reliability, network switch shall:

 be Rated for Gigabit Ethernet;

 be Non-blocking;

 have Quality of Service (QoS) with at least four queues;

 have Diffserv (DSCP) QoS with strict priority;

 have EEE (Energy efcient ethernet) switched off.

For detailed information on setting up a switch, please refer to
the manufacturer’s documentation.

8 : 2.1. Redundant network configuration

Dante Redundancy can be set up and used between any
supporting Dante-enabled audio equipment: it works by using
two completely independent and separate networks, the Primary
Network and the Secondary Network.

To setup and use Dante Redundancy, connect the Ottoca­nali DSP+D amplier and other redundant Dante-enabled audio
equipment using duplicate Gigabit switches and Ethernet cables.
Connect your computer running Dante Virtual Soundcard and
Dante Controller, and other non-redundant Dante-enabled audio
equipment to the Primary Network.

The primary and secondary networks MUST NOT be inter­connected at any point. Make sure any computer is set to auto­matically congure its IP address.

9 : 1.Signal routing and DSP architecture

Signal processing on Powersoft Ottocanali DSP ampliers
accomplishes multiple functions that affect the audio signal before
power amplication; 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:

 Input source selection. The input section allows you to

manage input gain and delay of analog and digital sources,
in order to compensate transmission latency and levels. Fur­thermore the Ottocanali DSP+D implement a backup policy
aimed to improve reliability against signal fault.

 Matrix. The innovative routing engine of Ottocanali DSP

allows any input to be routed to any output. The Matrix
implements a non-boolean rooting architecture allowing free
channel assignment and level adjustment.

Armonía Pro Audio Suite is the default conguring interface
that allows system setting and customization of the Ottocanali
DSP+D ampliers.

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 running 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 ampli­er – allows you to highlight the presence of the amplier into the
Armonía Workspace.

Once connected to Armonía Pro Audio Suite a double click on
the amplier icon in the Workspace will open the amplier dashbo­ard. Here it is possible to access and congure all the features of
the Ottocanali DSP.

9 : 2.Purposed workflow

Once the loudspeaker layout has been dened, we suggest a
bottom-up conguration procedure that starts from the congura­tion of the transducers layout and raises toward the input selection
and the denition of the backup policy.

Shortly, the main steps to follow are:

1. Set Lo-Z and Hi-Z loads and lters on output channels.

2. Load the loudspeaker presets or manually congure the
loudspeaker layout (grouping output channels, crossovering,
limiting, speaker processing, etc.).

3. Dene 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
dene the backup policy (input source selection).

5. Dene GPO assignment and alarms thresholds.

 Advanced processing. This allows you to optimize levels

and shape the sound of the input signals. Gain and polarity
adjustment, asymmetric raised-cosine full parametric lters,
delay and mute are available on each channel routed to the
speaker section.

 Speaker equalization. Designed to manage the conguration

presets for multi-way systems, it implements FIR and IIR full
parametric lters.

 Speaker routing. Once properly grouped, the output chan-

nels 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.

 Output processing. This allows ne tuning of output signals,

aiming to optimize power delivering and loudspeaker per­formance. It provides gain and polarity adjustment, IIR and
FIR full parametric lters, delay, mute, limiting and damping
control on each output channel.
