Preliminary operations
Location
Install your Community Amplified Loudspeaker Controller (ALC) 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 ALC far from EMF emitting devices.
Avoid placing the ALC close to heat generating sources.
Cooling
The ventilation openings must not be impeded by any item, keep
a distance of at least 19.7 in. (50 cm) from the front and rear
ventilation openings of the ALC.
Community ALCs implement a forced-air cooling system to
maintain constant operating temperatures. Air enters from the
front panel, exiting at the back of the unit.
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
channel s until the ALC cool s down to a safe o perating tempe rature.
Normal operation is resumed automatically without the need for
user intervention.
ALCs can be stacked one on top of the other, leave one rack unit
empty every four to guarantee adequate air flow.
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 ALCs connected to the same outlet is such that one
can reach the critical power absorption of the line.
When ac tivated, th e Breaker Save halves th e maximum continuou s
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/O
Remote ON/OFF is available through the dedicated terminals on
the rear panel.
Both terminals respond to the dierential voltage between the
contacts: a voltage dierence in the range 5 V
the control. Any voltage exceeding 28 VDC may damage the input
circuitry.
The couple of terminals act depending on the actual state of the
ALC, in accordance with the following table.
REMOTE ON REMOTE OFF ALC STATE
Vdi ≥ 5V Any Force Turn ON
Vdi < 3V Vdi ≥ 5V Force Turn OFF
Vdi < 3V Vdi < 3V
(Keep either standby or in current state)
No Change
- 24 VDC triggers
DC
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 ALC’s operating environment.
In order to clean the vent filters remove the front cover by firmly
gripping the outermost black panels and pull them outwards
Use compressed air to remove the dust from filters, or wash them
with clean water (let the filter dry thoroughly before reinstalling
them).
AC Mains Supply
ALCs 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 ALC On and O
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 o.
In order to toggle the ALC between ON and STANDBY press and
hold the power button for 3 seconds. Please consider that the
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 o to
further save energy (Time out time is selectable via ArmoníaPlus).
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.
Gain selection
ALCs can operate with dierent 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 ALCs. 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
Analog Audio Input Connections
Analog input connections are made via the Phoenix MC
1,5/6-ST-3,81 5447900 connector on the ALC-3202D (or via the
Phoenix MC 1,5/12-ST-3,81 1803675 connector on the ALC-404D or
AL C-1 6 04 D).
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 all channels.
The remote level controls are in series with the level adjustment
knobs in the front panel.

Digital Audio Input Connection
All ALC s accept two/fo ur input strea ms from the Dan te® connection
through the Dante® 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 have to be used. Dante® Controller is a
software application that manages devices on the network. ALCs
are automatically discovered and displayed in Dante® Controller
with the default identifier:
MODELNAME-SERIAL
(e.g.ALC-3202D-71520).
Ethernet Connection
The port labeled Ethernet is designed to remotely control the
ALC via an Ethernet connection through a personal computer and
Powersoft ArmoníaPlus System Manager software.
Powersoft recommends 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 (or PC 5/8-STF1-7,62 177891 port ALC-404D/1604D).
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 can drive 70V/100V (Hi-Z) distributed line
loudspeakers. To connect any channel’s output to a 70V/100V line,
set the rear panel DIP switch corresponding to the channel.
When using Community ALC's with factory-authored loudspeaker
presets, it is not necessary to use the built-in HPF (High Pass
Filter) DIP switches on the rear of the amplifier. While these
switches can select a HPF of 35Hz or 70Hz, each Community 70V
/ 100V loudspeaker preset already includes a HPF appropriate for
the selected loudspeaker model.
Low-Z 2Ω Load Operation
The 2Ω switch allows activation of all output channels set to
match the low impedance operating condition (i.e. in Low-Z
configuration) optimizing the performance with very low loads,
by limiting the maximum output voltage to 85 Vpeak per channel.
When using ALC's with Community-authored loudspeaker
presets this switch becomes redundant and can be ignored. Each
loudspeaker preset already includes limiters preset to values that
will limit voltages to safe operating levels.
If using an ALC without a Community-authored loudspeaker
preset, use this switch as intended for 2Ω loads. Never connect
loads lower than 2Ω to any output channel on any ALC under any
circumstances.
Diagnostics - GPO - Alarms
ALCs provide a pair of paralleled general purpose output
connections per channel: one Normally Open NO and one
Normally Closed
The connections are available on the back panel via the 6-pin
(ALC-3202D) or 12-pin (ALC-404D/1604D) Phoenix connectors.
When the am plifier is in nor mal operat ing condition t he NO contac ts
are closed, while 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)
ALC is in Standby
All ALCs feature further monitoring on pilot tone and output load
through ArmoníaPlus System Manager.
NC.
Self Check
The self check procedure tests the ALC 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 the self check push button once
If self check cannot be started because of a fault, the check LED
will blink fast, while 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 use d 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 ALC 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
ALCs support star network topology via the Ethernet port and
Dante® networking via the Dante® port.
IP Addressing
Factory default network settings are DHCP/AutoIP.
In order for the ALC to self-configure when connected to an
existing LAN or PC. Fixed IP policy can also be adopted and
configured through ArmoníaPlus System Manager.
If a DHCP server is not active within the network, the ALC platform
initiates a stateless address auto-configuration (i.e. Zeroconfiguration networking methodology). 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 ArmoníaPlus and the ALC must belong to the same subnet. If
a DHCP server is present on the network and an ALC is in AUTO IP,
networking may become unstable.
IMPORTANT: As a rule of thumb, turn the DHCP server ON before
connecting the ALCs.
IP addressing of an ALC 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 ALC does
not reveal a DHCP server on the network during the startup, it sets
itself in AUTO IP mode.
ArmoníaPlus System Manager
ArmoníaPlus System Manager is the configuring interface
that allows system setting and customization of the ALCs.
ArmoníaPlus can be installed on a PC running Windows (7 and
higher). Download ArmoníaPlus System Manager for free from
the website: http://www.communitypro.com/armoniaplus
Input Selection and Backup Policy
it is possible to selec t among two input signal source s per channel:
analog and Dante® streams. ArmoníaPlus System Manager
software provides an interface to select the input source.
Furthermore ALCs implement a backup policy aimed to improve
reliability against signal fault. By assigning a bus priority to the
two dierent 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 System Manager 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 ALCs.
