Location
Install your Duecanali/Quattrocanali Amplifier in well ventilated rack
cabinets.
Secure both front and rear brackets to the rack.
Connect the AC Mains connector to a circuit breaker.
Install the amplifier far from EMF emitting devices.
Avoid placing the amplifier close to heat generating sources.
Cooling
The ventilation openings must not be impeded by any item, keep a distance of
at least 50 cm from the front and rear ventilation openings of the amplifier.
Duecanali/Quattrocanali implements a forced-air cooling system to maintain
constant operating temperatures. Air enters from the front panel, exiting at
the back of the amplifier.
The cooling system features variable-speed DC fans controlled by the heat sink
mounted sensors. This ensures that fan noise and internal dust accumulation
are kept to a minimum.
In the rare event of overheating, sensing circuits shut down all channels
until the amplifier cools down to a safe operating temperature. Normal
operation is resumed automatically without the need for user intervention.
Duecanali/Quattrocanali amplifiers can be stacked one on top of the other,
leave one rack unit empty every four to guarantee adequate air flow.
Cleaning
Use a dry cloth for cleaning the chassis and the front panel. Air filter
cleaning should be scheduled in accordance with the dust levels in the
amplifier’s operating environment.
In order to clean the vent filters remove the front cover by firmly gripping
the outermost silver panels and pull them outwards Use compressed air to
remove the dust from filters, or wash it with clean water (let the filter
dry thoroughly before reinstalling them).
AC Mains Supply
Duecanali/Quattrocanali Series amplifiers implement an universal switching
mode power supply with power factor correction operating in the range from 100
VAC up to 240 VAC ±10%.
AC mains connection is in the rear panel through the IEC C20 inlet, the
approved power cord is provided.
Switching the amplifier On and Off
Once properly powered (power cord inserted, sectioning breaker closed), the
system can be either ON or in STANDBY mode depending on its state at latest
power off.
In order to toggle the amplifier between ON and STANDBY keep
pressed the power button for 3 seconds. Please consider thathe operating
condition can be modified by the REMOTE ON and REMOTE OFF configuration.
Energy Save
The Smart Rails Management technology implemented in the power supply unit
allows to reduce the power consumption when the input signal falls under a
defined threshold.
When On, Energy Save is active on each channel independently.
If the signal is missing for more than 30 minutes on all channels, the auto
standby is applied and the main PSU is turned off to further save energy (Time
out time is selectable via Armonía in DSP+D Versions). Normal operation is
resumed in a matter of milliseconds when an incoming signal is detected.
In order to activate the Energy Save feature, operate the NRG SAVE dip switch
on the rear panel.
Breaker Save
This feature may be activated when the power grid is unable to provide enough
current to continuously drive the loads, or when the number of amplifier
connected to the same outlet is such that one can reach the critical power
absorption of the line.
When activated, the Breaker Save halves the maximum continuous current
absorption from the mains. This slightly reflects on the overall performance
of the system, reducing the available output power.
In order to activate the Breaker Save feature, locate the BRK SAVE switch on
the rear panel.
Remote On/Off
Remote ON/OFF is available through the dedicated terminals on the rear panel.
Both terminals respond to the differential voltage between the contacts: a
voltage difference in the range 5 VDC – 24 VDC triggers the control. Any
voltage exceeding 28 VDC may damage the input circuitry.
The couple of terminals act depending on the actual state of the amplifier, in
accordance with the following table.
| REMOTE ON | REMOTE OFF | AMPLIFIER STATE |
|---|---|---|
| Vdiff ≥ 5V | Any | Force Turn ON |
| Vdiff < 3V | Vdiff ≥ 5V | Force Turn OFF |
| Vdiff < 3V | Vdiff < 3V | No Change |
(Keep either standby or in current state)
Gain selection
The Duecanali/Quattrocanali Series amplifiers can operate with different gain
applied to the input signal. This feature is designed to match the voltage of
the input signal.
A proper combination of the position of two GAIN switches on the rear panel
sets the operating gain of the amplifier
Connections
Signal Grounding
There is no ground switch or terminal on the Duecanali/Quattrocanali Series
amplifiers. 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.
Analog Audio Input connections
Analog input connections are made via the Phoenix MC 1,5/6-ST3,81 5447900
connector.
Remote Level adjustment
The level of each channel can be remotely adjusted by means of a linear 10 kΩ
potentiometer connected to the input LEVEL connector.
When the CH1 MSTR switch is in the OFF position the remote level
potentiometers work independently on each separate channel.
When the CH1 MSTR switch is in the ON position the remote level potentiometer
of channel 1 acts as a master level, controlling the volume of both channels.
The remote level controls are in series with the level adjustment knobs in the
front panel.
Digital Audio Input connection
Dante/AES67 enabled models accepts two input streams from the dedicated audio
over IP port. Cabling must comply to TIA/EIA-568-B and adopt the T568B scheme
pinout.
In order to implement a Dante network, a computer running Dante Controller is
a software application that manages devices on the network.
Duecanali/Quattrocanali DSP+D amplifiers are automatically discovered and
displayed in Dante Controller have to be used. Dante Controller with the
default identifier: MODELNAME-SERIAL (e.g. Duecanali1604-71520).
Ethernet connection
The port labelled Ethernet is designed to remotely control the amplifier via
an Ethernet connection through a personal computer and Powersoft ArmoníaPlus
software.
Powersoft recommend the use of Ethernet Cat5 straight through –patch – cables
with pin/pair assignments TIA/EIA-568-B, i.e. T568B.
Output connections
Output connections are made via the Phoenix PC 5/4-STF1-7,62 177859 port.
Any mixed configuration of low and high impedance output loads can be made: in
order to set the load configuration, each channel is provided with four DIP
switches.
Hi-Z 70V/100V operations
Any channel of can drive 70V/100V (Hi-Z) distributed line loudspeakers. In
order to connect any channel’s output to a 70V/100V line, the rear panel DIP
switch corresponding to the channel must be set.
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,
two cutting frequency are available 35 Hz and 70 Hz.
Lo-Z 2Ω load operation
Duecanali/Quattrocanali Series amplifiers are optimized for working with 4Ω
output loads but a special configuration allows to connect low loads down to
2Ω.
The 2Ω switch allows to activate on all output channels set to match low
impedance (i.e. in Lo-Z configuration) an operating condition that optimizes
the performance with very low loads, by limiting the maximum output voltage
to 85 Vpeak per channel.
For optimal 2Ω performance, it is recommended to select LowZ mode for all the
amplifier’s channels.
Note that 2Ω capabilities are not supported by 4804 models, the dip switch is
therefore marked “USR C”, and its function is reserved.
Diagnostics – GPO – Alarms
Duecanali/Quattrocanali 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 the 6-pin
Phoenix MC 1.5/6-ST-3.81 5447900 connector.
When the amplifier is in normal operating condition the NO contacts are
closed, whilst the NC contacts are open, and vice-versa.
These contacts are used to report potentially dangerous faults or generally
unsafe operation conditions by toggling alarm switches relative to the
following events, and any fault preventing the normal operation of an output
channel:
No AC mains (i.e. system shutdown);
Thermal stress: the system temperature is too high and the thermal protection
is engaged;
Short circuit in output wiring: either the loudspeaker or the line is in
short;
Amplifier is in Standby
DSP+D versions feature further monitoring on pilot tone and output load trough
ArmoníaPlus.
Self Check
The self check procedure tests the amplifier status and reports the user in
case of failures.
After few minutes, at the end of the self check procedure, a combination of
lit LED in the LED panel provides information about the amplifier status.
In order to exit the self check test and resume normal operations, press once
the self check push button 6.
If self check cannot be started because of a fault, the check LED will blink
fast, whilst a reassuring slow blink is an indication of a completed self
check procedure.
Pilot Tone monitoring
The detection of a mismatch in the input pilot tone parameters (frequency and
voltage level) can be used to trigger the 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 amplifier or the internal post DSP pilot tone generator; in both cases any
mismatch between the detected signal and the set thresholds triggers the
general purpose output switches.
Networking
Duecanali/Quattrocanali amplifiers support star network topology via the
Ethernet port and Dante™ /AES67 dedicated AoIP port.
IP Addressing
Factory default network settings are DHCP/AutoIP.
In order for the amplifier to self-configure when connected to an existing LAN
or PC. Fixed IP policy can also be adopted and configured through ArmoníaPlus.
If a DHCP server is not active within the network, the amplifier platform
initiates a stateless address auto-configuration (i.e. Zero-configuration
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 host names of the networking devices.
Both Armonia and the Duecanali/Quattrocanali must belong to the same subnet.
If a DHCP server is present on the network and a Duecanali/Quattrocanali
amplifier 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 a Duecanali/Quattrocanali amplifier is established during the
bootstrap: when the amplifier discovers a DHCP server on the network during
the startup, it negotiates the networking parameters. If the
Duecanali/Quattrocanali does not reveal a DHCP server on the network during
the startup, it set itself in AUTO IP mode.
ArmoníaPlus
ArmoníaPlus is the default configuring interface that allows system setting
and customization of the Duecanali/Quattrocanali DSP+D amplifiers. Armonía can
be installed on a PC running Windows (XP SP3 and higher).
Download ArmoníaPlus for free from the dedicated website:
https://www.powersoft.com/en/software/armoniaplus/
Input selection and Backup Policy
In Duecanali/Quattrocanali DSP+D and amplifiers it is possible to select among
two input signal sources per channel: analog and Dante/AES67 streams.
ArmoníaPlus software provides an interface to select the input source.
Furthermore Duecanali/Quattrocanali DSP, DSP+D, and DSP+ amplifiers implement
a backup policy aimed to improve reliability against signal fault. By
assigning a bus priority to the two different input sources per channel, the
system is able to automatically switch to a reliable input connection in case
of signal drop or pilot tone mismatch.
Output Load monitoring
Through the ArmoníaPlus software it is possible to set the thresholds on the
load impedance, at given frequency, that trigger the general purpose output of
any channel in Duecanali/Quattrocanali DSP, DSP+D, and DSP+ amplifiers.
