extraordinary maintenance.
1.4 Speaker Damage
!
Powersof t Class D ampliers are among the most powerful
professional ampliers available and are capable of producing
much more power than many loudspeakers can handle. It is the
user’s responsibility to use speakers suitable to the amplier and
to use them in a sensible way that will not cause damage.
Powersof t will not be held responsible for damaged speakers.
Consult the speaker manufacturer for power handling
recommendations.
Even if you reduce the gain using the amplier’s front panel
attenuation controls, it is still possible to reach full output power if
the input signal level is high enough.
A single high-power tone can damage high frequency drivers
almost instantaneously, while low frequency drivers can usually
withstand very high, continuous power levels for a few seconds
before they fail. Reduce power immediately if you hear any
speaker “bottoming out” - harsh pops or cracking distortion that
indicate that the speaker voice coil or diaphragm is striking the
magnet assembly.
Powersof t recommends that you use ampliers of this power
range for more headroom (cleaner sound) rather than for
increased volume.
1.5 Speaker Output Shock Hazard
A Class D amplier is capable of producing hazardous output
voltages. To avoid electrical shock, do not touch any exposed
speaker wiring while the amplier is operating.
This manual contains important information on operating your
Powersoft amplier correctly and safely. Please read it carefully
before operating your amplier. If you have any questions,
contact your Powersoft dealer.

3.1 Introduction
Congratulations on buying a Powersoft Ottocanali amplier!
Powersof t is a leading company in the eld of high efciency
audio power management. The Powersoft Class D technology
has changed the way the world looks at professional audio
amplication: no other amplier’s per formance comes close for
applications demanding high power and long term reliability.
Thanks to amazing reductions in heat output and weight, without
sacricing output powers, Powersoft ampliers can be used in an
unlimited range of PA applications such as opera houses, theaters,
churches, cinema, and theme parks.
3.2 The Ottocanali Series
The Ottocanali series of ampliers are specically designed for
installation applications. The ampliers in this series offer smaller
dimensions, lighter weight and the traditionally amazing sound
quality and reliability of all Powersoft products. The PFC (Power
Factor Correction) feature allows awless worldwide operation
with any AC mains voltage, including110V and 220V.
3.3 More Sound and Less Weight
Class D technology based ampliers are highly efcient, delivering
greater power to speakers with reduced heat dissipation: typical
running efciency of output stages is 95%, with only 5% of input
energy dissipated as heat. This allows for smaller dimensions,
weight and power consumptions.
Contrary to conventional ampliers which achieve highest
efciency only at full rated power output, Class D efciency is
almost independent of output level. Music has an average power
density of 40% of its peak value; this means that other (nonclass D) ampliers can easily generate 10 times more heat than
Powersof t products for the same sound pressure level. This unit
is designed to work with lo-Z (from 4 Ω) and with 70V/100V
distributed lines. It can deliver up to 150 W per channel (at 4 Ω)
or 300 W in bridge mode on 8 Ω. The DSP + ETH version allows
single channel processing and remote control of the amplier.
Powersof t ampliers deliver crystal-clear highs, and a tight, welldened low end: the most accurate reproduction of an audio
signal. Solid time proven design features ensure extremely high
performance in terms of super low total harmonic distor tion,
optimal frequency response, high power bandwidth and damping
factor across a vast number of application scenarios. Powersoft’s
multi patented application of Pulse Width Modulation (PWM)
high frequency sampling techniques is just one of the many factors
contributing to the Ottocanali’s high per formance ratings across
the audio bandwidth.
The Show Always Goes On
The Ottocanali series offers complete protection against any
possible operation error. Every amplier in this series is designed
to work under a large range of possible conditions, delivering
maximum power with maximum safety and an outstanding long
term reliability. Anticipating potential problems at the design stage
means your show always goes on!
4 Installation
4.1 Unpacking
Carefully open the shipping carton and check for any noticeable
damage; the gure below (FIGURE 1) shows the packing view.
Every Powersof t amplier is completely tested and inspected
before leaving the factory and should arrive in pristine condition.
In the unlikely event that you should encounter any damage,
please notify the shipping company immediately. Be sure to save
all packing materials for the carrier’s inspection.
The Ottocanali box contains the following:
▶
1 Ottocanali amplier
▶
1 x AC Mains cord with 3-pin plug 15A for US, IEC ‘Schuko’
16A for every other nation.
▶
6 x 12 pin Phoenix MC 1.5/12-ST-3.81 1803675 connectors
▶
2 x 4 pin Phoenix MC 1.5/4-ST-3.81 1803594 connectors
▶
1 x 16 pin Phoenix MSTB 2.5/16-ST-5.08 1757158 connectors
FIGURE 1: Ottocanali box
4.2 Mounting
All Powersoft ampliers are designed for standard 19” rack
mounting; there are four front panel holes and two rear-lateral
holes. In order to limit the risk of mechanical damages, ampliers
must be xed to the rack using both frontal as well as rear
mounting holes (FIGURE 2).
Page 10
▶

Ottocanali 1204 User Guide
FIGURE 2: Amplier rack mounting holes, front and back
4.3 Cooling
All Powersoft ampliers implement a forced-air cooling system to
maintain low and constant operating temperatures. Drawn by an
internal fan, air enters through the slots in the front panel and is
forced over all components, exiting at the back of the amplier.
The amplier’s cooling system features an “intelligent” variable-
speed DC fan which is controlled by heat sink temperature sensing
circuits: the fan speed will increase only when the temperature
recorded 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 amplier 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
amplier should dangerously overheat, sensing circuits shut down
all channels until the amplier cools down to a safe operating
temperature. Normal operation is resumed automatically without
the need for user intervention.
When mounting Ottocanali ampliers, the exhaust heat should
be taken into consideration.. Exhaust cooling air is forced out
through the rear of the chassis (FIGURE 3); make sure there
is enough space around the back of the amplier for this air to
escape. Ottocanali ampliers can be stacked one on top of the
other due to the efcient 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
Ottocanali ampliers installed to guarantee adequate air ow.
FIGURE 3: Forced air cooling: front to back airow
4.4 Operating Precautions
Make sure the power switch is off before attempting to make any
input or output connections.
Make sure the AC mains voltage used is within the acceptable
operating voltage range specied in the Ottocanali documentation
(100V-240V ±10%). Damage caused by connecting the amplier
to an improper AC mains voltage is not covered by the warranty.
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.
4.5 Grounding
There is no ground switch or terminal on the Ottocanali Series
ampliers. All shield terminals of input connections are directly
connec ted to the chassis. This means that the unit’s signal grounding
system is automatic. In order to limit hum and/or inter ference
entering the signal path, use balanced input connections.
In the interests of safety, the unit MUST always operate with
electrical safety ear th connected to the chassis via the dedicated
wire in the 3-wire cable. Never disconnect the ground pin on the
AC mains power cord.
4.6 AC Mains Connection
The AC Mains connection is made via the IEC type connector on
the back of the amplier. The PFC feature allows the Ottocanali
to work within a range of different AC mains voltages without the
need to adjust any settings; however, make sure your AC mains
power source operates within the voltage limits indicated on this
manual (100V-240V ±10%). The 10A mains fuse and spare fuse
are located between the on/off switch and the IEC type mains
connector. Please see REF. FIGURE 3.
FIGURE 4: Mains connector and on/off switch
SAFETY WARNING! Ground wires must be connected! Do not
use adapters that disable grounding.
4.7 BatFormer®
It is possible to connect any Ottocanali channel directly to a
70V/100V distributed line using an optional BatFormer. BatFor mers
are specically designed to be easily installed by an authorized
service center.

5 Connections and Operation
5.1 Introduction
This section provides information on amplier connection and
operation. For optimal amplier performance, it is important to
understand the meaning of the information that the Ottocanali
amplier can provide regarding its status and conguration.
This information is available to the user both via front panel
indicators as well as through specic alarm signals broadcasted
from dedicated connectors on the back of the unit. This chapter
will break down all the front panel operations and monitoring
functions the Ottocanali is capable of. The remaining par t of
the chapter will explain how to correctly connect the amplier’s
inputs and outputs.
5.2 Front Panel Controls Access
A number of impor tant controls can be accessed by removing
the front left hand side protective panel bearing the Powersoft
logo. Both silver colored metal panels are attached to the chassis
magnetically and can therefore be removed quickly without the
aid of any specic tool.
The following procedure can be used to remove both the left as
well as the right hand front panels. Removing the right hand panel,
however, does not grant access to any controls and is useful only
for air lter access (see Section 8.3).
To remove the left hand side front panel bearing the Powersoft
logo:
1. Firmly grip the outermost left hand side of the silver colored
panel and pull outwards at an angle, as if opening a door
hinged on the right hand side
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.
FIGURE 11: Magnetic side panel removal
To reposition the left hand side silver panel:
1. Secure the air lter to the amplier chassis by placing it in its
designated area and press lightly, so that the lter’s central cut
hole can brace the magnetic snap mechanism
2. Align the silver panel’s right hand side to the chassis at the
same angle used to remove it
3. When correctly positioned, the magnetic snap mechanism
will automatically secure the metal panel in place.
The controls positioned behind the lef t hand side silver colored
Powersof t logo panel allow access to a series of important features:
▶
Output channel attenuation adjustment (see Section 5.3.1)
▶
Preset selection, one per channel pair (DSP version only)
▶
AUX Input/Line Input toggle (see Section 5.5)
▶
GPIO operations (see Section 5.10)
▶
Channel pair energy save mode selection (see Section 5.3.2)
5.3 Front Panel Adjustments
There are two types of adjustments that are possible from the
Ottocanali front panel: output level attenuation and energy save
mode.
5.3.1 Output Level Adjustments
Removing the left hand side metallic panel exposes one attenuator
knob for each channel, numbered one through eight starting from
the left hand side. Each channel’s output attenuation level can
be set to any value from 0 to ∞. Attenuation level decreases by
rotating the blue knob clockwise.
FIGURE 12: Front panel left hand side output attenuator s
5.3.2 Energy Save
Energy save capabilities can be activated for each channel pair.
When the energy save mode is activated 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.

5.4 Front Panel Monitoring
The Ottocanali front panel provides important information on the
state of the amplier. It is important to know and understand the
meaning of every front panel indicator in order to have crucial
information on the operational state of the amplier.
There are two sets of LEDs on the Ottocanali front panel. On the
upper portion of the left hand side of the front panel are 16 LEDs,
4 for each channel pair, available for DSP functions.
FIGURE 16: Front panel left hand side DSP LEDs
For models including a DSP: the lighted LED indicates which preset
is active for that specic channel pair. The rst lef tmost set of 4
LEDs refers to channels 1 and 2, the second set of 4 LEDs refers to
channels 3 and 4 and so on. Preset parameters are dened, set and
modied by connecting the Ottocanali amplier to a computer
using the Armonía Pro Audio Suite software. The pushbutton
on the lef t of each set of 4 LEDs allows to manually select the
preset for that particular channel pair. Pushing the button will cycle
between all 4 available presets.
On the central portion of the front panel of the Ottocanali are 8
columns of 7 LEDs, one column for each channel.
FIGURE 17: Front panel LEDs
Some of these LEDs have multiple signaling modes, e.g. metering
or alarm modes. Their function is summarized in the following
chart:

5.5 Connecting Audio Inputs
Audio input connections are made via two 12-pin Phoenix MC
1.5/12-ST-3.81 terminal block connectors:
FIGURE 19: Audio input terminal block connector
Input connectors are placed on the back of the Ottocanali and
grouped in two rows:
FIGURE 20: Rows of input connectors
▶
The topmost line of connectors is for line input
▶
The second row of connectors is for auxiliar y input
Line Input/Aux Input toggle:
The amplier switches from line inputs to auxiliary inputs when a
constant voltage in the 12V to 30V range is applied to the “AUX
SEL” connector. When this voltage is removed from the “AUX
SEL” connector, the unit switches back from auxiliary inputs to
line inputs.
FIGURE 21: AUX SEL connector
The Ottocanali amplier provides an additional procedure to
switch from line inputs to auxiliar y inputs. The “PWS OUT”
connector can provide a 24V DC (0.2 A max, symmetrical with
respect to ground) when enabled by the left hand front panel
toggle switch.
FIGURE 22: AUX SEL and PWS OUT connection
FIGURE 23: PWS OUT por t on the back of the Ottocanali amp
By connecting the “PWS OUT” connector to the “AUX SEL”
(see FIGURE 22) the front panel switch will toggle between line
inputs and auxiliar y inputs. The following diagram explains the
relationship between the front panel toggle switch and the PWS
OUT port.
FIGURE 24: PWS OUT port vs front panel switch diagram
5.6 Connecting Audio Outputs
Warning! Lethal voltage levels may be present at the loudspeaker
connectors when the amp is turned on!
A 16-pin Phoenix MSTB 2. 5/16-ST-5.08 terminal block connector
is provided for the amplier’s output connections. The + pin of
the connector corresponds to the positive output of the channel.
Ensure that the speakers are connected to the Ottocanali output
with the correct polarity.
FIGURE 25: Audio output terminal block connector
Both bridge as well as single end output connection modes are
possible and can be mixed: for example, channels 1 and 2 can
Page 16
▶
16
Ottocanali 1204 User Guide
be connected in bridge mode, while channels 3 and 4 can be
connected single end.
REF. FIGURE 4 summarizes common connection modes with
corresponding connection polarities. Speaker cables are labeled
as spk X_+ and spk X_-, where X represents the speaker number.
5.7 Lo-Z and 70V/100V Operations
Any channel of the Ottocanali amplier can drive either a lo-Z or
a 70V/100V (hi-Z) line. In order to connect any channel’s output
to a 70V/100V line, the factory supplied connection jumper must
be replaced with a BatFormer (optional). Please refer to 4.7 for
instructions on how to correctly install a BatFormer. BatFormer
installation must be carried out by authorized ser vice centers.
5.8 Bridge Mode Connection
Bridge mode connection of outputs is possible only in lo-Z
operational mode. Bridging of adjacent channels is allowed for the
following pairs: channels 1 with 2, 3 with 4, 5 with 6, 7 with 8.
Bridiging is NOT possible for other pairs, for example channels
4 and 5. In order to obtain a bridge connection of the outputs,
inputs must be connected in parallel and outputs in series on
a minimum load of 8 Ω . Please refer to REF. FIGURE 6 for a
connection diagram example.
5.9 Parallel Mode Connection
Parallel connection of output channels is allowed only for hi-Z
operational modes; this means that in order to connect output
channels in parallel, these MUST be equipped with optional
BatFormers. Only the following channel pairs can be connected in
parallel: 1 with 2, 3 with 4, 5 with 6, 7 with 8. Parallel connection of
channels 4 with 5, for example, is not allowed. In order to obtain
this kind of connection, both the input channel pair as well as the
output channel pair must be connected in parallel. Please refer to
REF. FIGURE 7 for a connection diagram example.
5.10 GPIO Operations
General Purpose Input/Output Operation (GPIO) refers to a
generic two pin contact (balanced or unbalanced) that can control
or can be controlled by another system. The Ottocanali’s GPIO
system implements digital trigger signals to broadcast alarms or
allow remote unit on/off switching.
5.10.1 Alarms
To ensure problem-free and efcient interaction with external
devices, the Ottocanali provides two 12-pin Phoenix MC 1.5/12ST-3.81 connectors on the back panel.
FIGURE 26: Back panel alarm output connectors
These contacts are used to report potentially dangerous faults or
generally unsafe operation conditions by toggling alarm switches
relative to events such as:
▶
DC presence at the outpu t: when a dange rous DC component
is present in the output power signal
▶
Thermal stress: when heat dissipation is not sufcient and
heat sink temperature rises.
For a detailed account of protective measures relative to these
alarms, please see Chapter 7.
5.10.2 Remote ON/OFF
By applying 24V DC (range from 15V to 30V DC) to the “REM
OFF” connector located at the back of the Ottocanali, the
amplier can be remotely switched on and off. When a 24V DC
voltage is applied to the REM OFF 2-pin Phoenix MC 1.5/4-ST-
3.81 connector, the amplier switches off immediately. When the
24V DC voltage is removed, the amplier switches back on as per
normal boot up operation.
FIGURE 27: REM OFF connector
5.10.3 Ethernet Port and Remote ID Selection*
The rear panel of the Ottocanali has one RJ45 port, 100Mbit
autosense Ethernet port for networking purposes. Below these
ports are two numeric encoders that enable remote ID selection,
needed to identify the amp when it is connected remotely. The
left hand side dial sets the tens while the right hand side sets the
units. Valid ID numbers go from 01 to 99.
FIGURE 28: REM OFF connector
5.10.4 V ext*
The “V ext” terminal, located on the rear panel of the Ot tocanali, is
used to supply the amplier’s internal Ethernet controller with the
minimum required power for remote on/off switching operations.
When the V ext port is powered by and external 9 V- 12 V DC
(1 A) power supply, the Ethernet controller is enabled to listen for
incoming connections such as device power-on commands.

5.11 DSP features and operations*
5.11.1 What Are DSP Operations? What Are They For?*
The main purpose of Digital Signal Processing (DSP) operations is
to allow the end user to program signal handling and processing
in order to:
1. Select and handle the source signal
2. Process the signal for system operation
3. Process the signal to improve multi way speaker sound quality
and protect speaker drivers
Furthermore, the DSP allows access to real-time information
on the internal device operation, which allows better and faster
amplier response in terms of control as well as providing the
end user with reliable information on what’s happening inside the
device.
5.11.2 DSP Features*
The Ottocanali amplier DSP is based on the DSP-C, a
multiplatform board used in many Powersoft products. Based on
Analog Devices’ ADAU 1701, the DSP-C board’s exible design
caters a wide range of users: from the speaker manufacturer
to the end user of rack ampliers. The DSP-C provides both a
completely programmable DSP to the experienced user as well as
a complete tool with remote control for the end user. The ADAU
1701 device is a xed point DSP with 26-bit resolution for the
internal path and 56-bit for internal processing. The board also
provides full remote control through Armonía Pro Audio Suite.
The Ottocanali DSP is modular for any channel pair, meaning, for
example, one module is available for channels 1 and 2 and another
for channels 3 and 4 and so on. Keep in mind that the modules
are physically separated, therefore input or output from different
modules can’t be mixed together.
Input routing selection and internal signal route. Keep in mind
that due to the internal structure it is impossible to mix signals
between non adjacent channels, for example channels 1 and 4
cannot be mixed together but only channels 1-2, channels 3-4,
channels 5-6 and channels 7-8 can. The following congurations
are possible for any channel pair.
▶
Mono input from IN1

6.2.1.1 DHCP*
When the data cable is connected the amplier begins DHCP
handshaking. If a DHCP server is present on the network , the unit
is ready to be remotely controlled.
6.2.1.2 AUTOIP*
Every device tries to set up network communication when the
data cable is plugged in and connected to another device (PC,
switch, etc.). If a DHCP server is not active in the device network
the units initiates a stateless address auto-conguration. It self
assigns a link-local address of the type 169.254.x.y with a subnet
mask 255.255.0.0. Please make sure that your PC is in the same
subnet of the unit. Modern operating systems provide Zeroconf
features for network auto-conguration.

response) curve displayed is always obtained as the combined
response of all currently active lters.
FIGURE 47: The input eq layer.
6.5.3 Output Eq.*
This page’s general appearance is similar to that of the Input
Equalizer page, but presents several impor tant differences. The
Output Eq. curve the amplier employs is meant to be created from
the speaker manufacturer’s data for the par ticular loudspeaker
cabinets or arrays the amplier will be driving. It provides a range
biquad lter that can act as crossover or generic IIR lter. Refer to
Section 5.11.3 for more information. From this page, the frequency
response of each channel can be adjusted in several ways. Discrete
time delays can also be inserted. The presence of every output eq.
present in the device layout is reported on the tabbed channel on

6.5.4 Limiters*
The function of the limiters is to protect voice coils from burning
out due to excess power being delivered over an extended period
of time or from excessively large signal peaks by limiting the
maximum output voltage of the amplier. The limiter window is
accessible by clicking on the limiter block in the device layout view.
Every channel limiter is color coded:light blue for channel 1, red
for channel 2, light green for channel 3, yellow for channel 4, dark
blue for channel 5, purple for channel 6, dark green for channel 7
and orange for channel 8.
FIGURE 49: The limiters window.
6. 5.4.1 RMS Limiter*
Electromechanical transducers are highly inefcient; as such
they transform a signicant amount of input power into heat.
The function of the RMS limiter is to protect the voice coils of
speaker drivers from burning out due to excess power being
delivered over an extended period of time. The RMS limiter is set
by selecting a desired maximum power value but acts by limiting
output voltage; by applying Ohm’s law with a xed reference 8
Ohm load, the output voltage level corresponding to the desired
maximim output power value is calculated as the square root of
power times the load resistance (8 Ohm). It is possible to set the
values of:
▶
Threshold in Watts, with respect to an 8 Ohm load.
▶
Attack time is the time between the moment the output
voltage exceeds the threshold and the moment of the onset
of the limiting action.
▶
Hold time is the length of time during which the limiting
action is maintained before the gain returns to normal levels
because the output voltage drops below the threshold level.
▶
Release time is the leng th of time over which the limiting
action is reduced and the gain is returned to normal follwing
the drop of the output voltage below the threshold level.
6.5.4.2 Peak Limiter*
The function of the peak limiter is to protect voice coils from
excessively large signal peaks by limiting the maximum output

voltage of the amplier. It’s possible set the values of:
▶
Threshold in Volts: the amplier max output voltage level
corresponding to the maximum displacement of the speaker
diaphragm.
▶
Hold time: the time over which the limiting action is
maintained before the gain level is returned to normal after
the output voltage drops below the threshold.
▶
Release time: the leng th of time over which the limiting action
is reduced and the gain is returned to normal follwing the
drop of the output voltage below the threshold level.
6.5.5 Locking*
The locking mechanism allows the user to prevent changes to a
whole preset or a part of a preset. The locking inter face is divided
in DSP module(s) and macro processing section (Refer to Section
5.11.4 for further information on the logical data section). Every
module needs to be locked separately; the lock status is preserved
with the impor t/expor t from/to le and copy/paste operations. In
order to lock/unlock an entire module or par ts of a module:
▶

7 Protection
In order to protect your device and your speakers from accidental
damage, the Ottocanali amplier includes an extensive automatic
protection system. In the following sections, potentially dangerous
scenarios and the amplier’s corresponding protective response
are explained in detail.
7.1 Turn On/Turn Off Muting
Class D amplier may cause severe speaker damage at power up
due to the high voltage levels at the output stage. In order to avoid
this, the outputs are muted for less than 2 seconds after turn on.
Similarly, turning off the amplier can cause the same problem:
outputs are muted immediately at turn off.
7.2 Short Circuit Protection
Shor t circuits or very low impedance loads may destroy the
output stage of any amplier. In order to protect the amplier
from the dangerously high current surges arising from accidental
output shor t circuits or low impedance loads, the Ottocanali
blocks channel activity when the current drawn from the load
rises above a set value.
7.3 Thermal Protection
All Powersoft ampliers have variable speed fans to assist cooling.
If for some reason the cooling system can’t dissipate the produced
heat correctly, a thermal protection system is automatically
activated to avoid permanent damages. Every channel pair of
the Ot tocanali has a temperature sensor on the output stage
heat sink. Two different protection strategies are implemented
depending on the severity of the overheating. In order to protect
internal components, the amplier may automatically reduce
output power until the internal temperature returns to safe levels.
7.3.1 Thermal Warning
If the heat sink temperature reaches 70°C the front panel yellow
LEDs turn on to warn the user of a potentially dangerous thermal
event.
7.3.2 Thermal Shutdown
II the heat sink temperature rises above 80°C, the thermal sensing
circuitry will mute each power section of each channel. All the red
front panel LEDs light on to indicate thermal halt and a thermal
event switch toggles all the alarm outputs at the back of the
amplier. Only after the heat sink has cooled down to below 70°C
the channels will automatically unmute, the LEDs turn off and the
rear switch toggles again.
7.4 DC Fault Protection
In order to protect your speakers from mechanical damage caused
by a DC signal coming from the amplier’s output, a DC detection
circuit is placed between the Ottocanali’s output stage and power
supply. If a DC signal or excessive subsonic energy appears at a
Page 27
▶
27
Ottocanali 1204 User Guide
channel output an instantaneous protection circuit will mute the
compromised channel pair.
7.5 Input/Output Protection
Inter ference protection is implemented in the Ottocanali to limit
out of band noise carried by the input lines. Disturbing frequencies
can interact with the output stage, causing unpredictable amplier
behavior. A ltering system is used to stop infrasonic and VHF
signals from entering the signal path.
7.6 Check Line Integrity and Impedence Measurement*
The integrity monitor tools allow the end user to program and
test the integrity of the input and/or output line. The input test is
based on the detection of a pure tone (generated by an external
tone generator) on any input lines. The output test is based on
the measurement of the impedance at a well dened frequency.
The amplier can generate a pure tone and measure the voltage
and the current at the generated tone frequency. It is therefore
possible to recalculate the impedance at that specic frequency.
When an alarm is detected the user can be informed of the event
via software or directly from the amplier. Bear in mind that there
is one generator for each channel pair.
FIGURE 55: GPO tab
This page can be found inside the Amplier view, tab GPO.
Slightly below each triangle containing the channel number is a
green LED that is lighted when a BatFormer is plugged in that
specic channel. When the LED is off, no BatFormer has been
installed on that channel. In the gure above, for example, channel
2 has a BatFormer installed, while channel 1 does not. BatFormer
presence can also be veried in the general Armonía overview
window. A lit green LED underneath the single channel will
conrm that a BatFormer is installed. In the following gure no
BatFormers have been installed.
FIGURE 56: General overview window
7.6.1 Programing Interface and Alarm Blocks Overview*
The input and the output section can be programmed separately;
however, they are logically divided by the processing section. This
means that the input tone can be ltered out, avoiding feeding it
to the output section. When an alarm triggers, this is reported in
Armonía in the following way: - One Armonía event (if selected)
will be activated - In the GPO page the blocks with an active alarm
become red.
On the amplier side an alarm will be repor ted as a blinking red
LED in the front panel and an alarm switches at the back of the
amplier.
7.6.2 Input Pilot Tone Detection*
The input tone detection can measure the integrity of any input
line feeding signal into the amplier. This detector can measure a
tone applied by an external generator. In the GPO overview the
input pilot tone block appears as seen in the gure below.
FIGURE 57: This control shows the threshold, the frequency and the
measured amplitude of the tone.
NOTE: suggested frequency values for the tone generator are
between 20 kHz and 22 kHz with the paying close attention to
cutting-off the tone before the output section.

7.6.4 Inner Pilot Tone Generator*
The inner tone generator allows the user to generate a tone that
can be used to check the integrity of the output line. This tone
must lie outside the speaker’s range limits to avoid hearing it in
the output.
NOTE: Typically a good value is between 20/40 Hz (20/22kHz if
BatFormer is used) with an amplitude between 2 and 4 V.

12 Appendix
Through Armonía Pro Audio Suite you can easily set the IP
conguration of your Ottocanali DSP+ETH as long as it is in
DHCP or is congured with a static IP on the same Armonía
subnet. It may happen that a static IP in a different subnet with
respect to Armonía has been assigned to your Ottocanali
DSP+ETH amplier (i.e. 10.0.x.y versus 169.254.x.y): if this is the
case Armonía does not recognize the amplier. You have to reset
the IP conguration of your amplier.
In order to reset the IP conguration of your Ottocanali
DSP+ETH amplier outside the Armonía environment, follow
next instruction.
12.1 Setting An IP Policy On ADAU Based Devices With An
External Lantronix Tool*
Ottocanali DSP+ETH ampliers come with one rear RJ45 port
for remote device communication, using the IP layer and the UDP
protocol. Factory default settings are DHCP/AutoIP, but a xed IP
policy can also be adopted.
12.1.1 Set IP conguration*
Adau based devices can be set up with a static IP (or any other
IP policy) with an external software programmer provided by
Lantronix™. In order to set up the IP address please follow the
following steps:
1. Download and install the DeviceInstaller™ software from the
Lantronix Web Site on your PC. Please refer to Lantronix
documentation.
2. Connect the device to your PC
3. Shutdown any M Series client (Armonía or third -party cli ent).
4. Launch the program: it should automatically scan your
network. If not, manually initiate the scan by clicking the
Search button.
NOTE: Due to the fact that the Lantronix congurator uses the
Etherner layer no IP set up is necessary.
All the available Lantronix-based devices should appear (see
FIGURE 71). Please note that devices that are not compatible with
the IP network mask of your network interface should appear too
due to the fact that the Lantronix Confgiurator uses the Ethernet
stack.
WARNING: Make sure that the only connected Lantronixbased devices are Ottocanali units. Any third-par ty device (e.g.
printers) that are equipped with a Lantronix unit are visbile with
this software.
Powersoft will be not responsible for any damage suffered by
third-party products equipped with Lantronix hardware.
12.1.2 Static IP*
1. Select the device whose IP address policy you want to set and
press the button Assign IP (see FIGURE 72)
2. Follow the Device Installer wizard. Any kind of IP policy can
be set.
FIGURE 65: Select assign specic IP and click next.
FIGURE 66: Select IP address and subnet mask compatible with your
PC. Specifying the gateway address is not mandatory. Click next.
FIGURE 67: When done press the Assign button.

12.1. 3 Revert From Static IP*
If for any reason re-programming the IP address or the IP policy
of your unit should be necessary, follow the instructions in the
previous chapter and make a different selection when assigning
the IP. For example, should you need to revert the device to the
IP factory settings, please follow these steps:
FIGURE 68: Select obtain an IP address automatically and click next.
FIGURE 69: Select IP address and subnet mask compatible with your
PC. Click next.
FIGURE 70: When done press the Assign button.
