Duecanali 1604 Amplifier
Architect’s and Engineer’s Specifications
The amplifier shall be a two-channel model with a switch mode power-supply with power factor
correction, smart rail management and bridgeable switch mode fixed frequency class D output
circuit topology. The amplifier shall operate from 100 V - 240 V, -10% / +10% 50/60 Hz, universal
AC input power with minimum voltage for power up at 90 V and shall draw 285,3W (2,39 A
@ 230V) or 258,4 W (4,2 A @ 115V) when driven with pink noise signal at 1/8 of rated power
into 4-ohm loads. Preferably the power supply of the amplifier should integrate Power Factor
Correction (PFC), in order to minimise interference with the electrical grid.
The amplifier shall be provided with an IEC C20 main detachable connector and power cord set
with IEC C20 connector on amplifier side and Schuko plug for EU and 3 Pin American plug on
the other. The amplifier shall have internal heat sinks cooled by a continuously variable speed fan
with a Microprocessor Temperature Control. Air flow shall be from front to rear. The amplifier shall
be able to drive low impedance loads (2/4/8 Ohm) and 70V/1 00V distributed lines selectable per
channel by using dipswitch settings at the rear panel of the amplifier. Furthermore, it shall be able
to provide more than 32 different possible output configurations (lo-Z, hi-Z, bridge mode, parallel
mode, and combinations of these).
The amplifier shall have Energy save capabilities that can be activated for each channel pair. In
energy save mode, the Amplifier shall enter a low power consumption idle state when no signal
activity is detected for more than 4 seconds. Normal operation shall be resumed in a matter of
milliseconds when an incoming signal is detected on the channel pair. In energy safe mode,
the power consumption shall not exceed 19W @ 230V or 19W @ 115V (0,45 @ 230V or 0,45A
@ 115V). In Idle mode, the amplifier shall not absorb more than 24W @ 230V or 23,1W @ 115V
(0,28A @ 230V or 0,40A @ 115V). Thermal dissipation of the amplifier will not exceed 291,2
BTU/h (@230 Volt) and 291,6 BTU/h (@110 Volt) when at 4 Ohm at 1/8 of maximum power.
The internal memory of the amplifier will contain of predefined pre-sets with cross-over settings
and will allow for more than 200 users pre-sets and snapshots to be stored.
The amplifier shall be equipped with remote On/off contacts and gain selection switches which
will allow the amplifier to operate with 26,29,32 and 35 dB gain applied to the input signal. The
amplifier shall implement HPF filter to either 35 Hz or 70 Hz configurable per channel.
The amplifier system shall implement triggering signals to broadcast alarms by providing a pair
of paralleled general purpose output connections per channel: one Normally Open (NO) and one
Normally Closed (NC). The GPO contacts will be used to report potentially dangerous faults or
generally unsafe operation conditions by toggling alarm switches relative in case of no AC mains,
thermal stress , short circuit in output wiring, amplifier is in Standby and any fault preventing the
normal operation of an output channel.
The amplifier shall offer remote level adjustment for each output channel. For ease of work the
amplifier will offer a CH1 Master setting that will allow remote control channel one to control the
volume for all of the channels of the amplifier.

The amplifier shall have a synchronized off-on muting, acting for four seconds after turn-on and
within 500mS after turn-off or loss of AC power. Each channel shall have DC protection in order
to protect against infrasonic signals and very low frequencies at the output stage that could
damage loudspeakers. Each channel shall have VHF protection in order to protect loudspeakers
from strong, very high frequency signals. Each channel shall have circuitry to protect against short
circuits or other stressful output circuits events. Each channel shall an independent clip limiter in
order to prevent severely clipped waveforms from reaching the loudspeakers, whilst maintaining
full peak power. Each channel shall have long term limiters in order to protect loudspeakers
against non-musical signals such as sine waves, feedback signals etc.
The amplifier shall contain a module which shall connect the amplifier to 100Mbps Ethernet
networks, allowing it to be remotely controlled and monitored via proprietary software running
on an external PC
The amplifier front panel shall provide ON LED and STANDBY LED, Armonía ID push button,
Soft Reset push button, Hard Reset push button, Self-Check function, Status LED strip, LED
signal metering per channel, level potentiometer per channel, power push button and a USB port
reserved for servicing.
The amplifier rear panel shall provide AC mains connector, Phoenix output connectors, Phoenix
line input connector, Phoenix GPI connector, Phoenix GPO connector, Phoenix, RJ45 Ethernet
connector, System configuration dip switches and output configuration dip switches.
