1.3 Safety Rules
!
This device must be powered exclusively by earth connected mains sockets in electrical networks compliant to the IEC 364 or similar rules.
It is absolutely necessary to verify this fundamental requirement of safety and, in case of doubt, require an
accurate check by qualied personnel.
The manufacturer cannot be held responsible for damages caused to persons, things or data due to an improper or missing ground connection.
Before powering this amplier, verify that the correct voltage
rating is being used.
Verify that your mains connection is capable of satisfying the power ratings of the device.
Do not spill water or other liquids into or on the amplier.
Do not use this ampliler if the electrical power cord is frayed
or broken.
Do not remove the cover. Failing to do so will expose you to potentially dangerous voltage.
No naked ame sources such as lighted candles should be placed on the amplier.
Provide a sectioning breaker between the mains connections
and the amplier. The suggested device is a 10A/250V AC (230V AC mains voltage) or 16A/250V AC (110Vac mains voltage), C or D curve, 10KA.
Contact the authorized service center for ordinary and extraordinary maintenance.
1.4 Speaker Damage
!
Powersof t Class D ampliers are among the most powerful professional ampliers 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 amplier 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 amplier’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 ampliers of this power range for more headroom (cleaner sound) rather than for
increased volume.
1.5 Speaker Output Shock Hazard
A Class D amplier is capable of producing hazardous output
voltages. To avoid electrical shock, do not touch any exposed
speaker wiring while the amplier is operating.
This manual contains important information on operating your Powersoft amplier correctly and safely. Please read it carefully before operating your amplier. If you have any questions, contact your Powersoft dealer.

3 Welcome
3.1 Introduction
Congratulations on buying a Powersoft Ottocanali amplier! Powersof t is a leading company in the eld of high efciency
audio power management. The Powersoft Class D technology has changed the way the world looks at professional audio
amplication: no other amplier’s per formance comes close for
applications demanding high power and long term reliability. Thanks to amazing reductions in heat output and weight, without
sacricing output powers, Powersoft ampliers 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 ampliers are specically designed for installation applications. The ampliers 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 ampliers are highly efcient, delivering
greater power to speakers with reduced heat dissipation: typical
running efciency 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 ampliers which achieve highest efciency only at full rated power output, Class D efciency is
almost independent of output level. Music has an average power
density of 40% of its peak value; this means that other (non­class D) ampliers 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 amplier.
Powersof t ampliers deliver crystal-clear highs, and a tight, well­dened 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 amplier 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 amplier 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 amplier
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 ampliers 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, ampliers must be xed to the rack using both frontal as well as rear mounting holes (FIGURE 2).
10
Ottocanali 1204 User Guide
FIGURE 2: Amplier rack mounting holes, front and back
4.3 Cooling
All Powersoft ampliers 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 amplier.
The amplier’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 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.
When mounting Ottocanali ampliers, 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 amplier for this air to escape. Ottocanali 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
Ottocanali ampliers installed to guarantee adequate air ow.
FIGURE 3: Forced air cooling: front to back airow
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 specied in the Ottocanali documentation (100V-240V ±10%). Damage caused by connecting the amplier
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
ampliers. 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 amplier. 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 specically designed to be easily installed by an authorized
service center.
11

5 Connections and Operation
5.1 Introduction
This section provides information on amplier connection and operation. For optimal amplier performance, it is important to
understand the meaning of the information that the Ottocanali
amplier can provide regarding its status and conguration.
This information is available to the user both via front panel
indicators as well as through specic 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 amplier’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 specic 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 amplier 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 amplier. 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 amplier.
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 specic 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 dened, set and modied by connecting the Ottocanali amplier 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.

Some of these LEDs have multiple signaling modes, e.g. metering or alarm modes. Their function is summarized in the following chart:
LED Color Solid ON Blinking
Red Channel output level has
reached clipping limits
OR
Channel has been muted
due to heat sink temperature
rising above 80°C
1)
Yell o w Channel output level is
above -6dB of max output
level
OR
Thermal warning: heat sink
temperature is above 70°C
2)
Green Channel output level is
above -12dB of max output
level
Green Channel output level is
above -24dB of max output
level
Green Input signal is above -60dBV
Green Channel is ready
Green -- AUX inputs
are selected

Even if only one channel causes thermal overload, all channels
are muted and all red LEDs are on.
