Radiation Exposure Statement
This equipment complies with RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

Preliminary operations

Location
Install your Biamp 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.
Biamp 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 channels until the ALC cools down to a safe operating temperature. 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.

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 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 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 off 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.

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 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 ALC, in accordance with the following table.

(Returns to last state set by front panel switch)

Gain selection
ALCs 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 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 wire.

Analog Audio Input Connections
Analog input connections are made via the Phoenix MC 1,5/6-ST-3,81 5447900 connector on the ALC-3202 (or via the Phoenix MC 1,5/12-ST-3,81 1803675 connector on the ALC-404 or ALC-1604).

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.

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.

Digital Audio Input Connection
ONLY AVAILABLE ON “D” MODELS. ALC “D” models accept two/four input streams from the Dante® 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. ALC-Ds are automatically discovered and displayed in Dante® Controller with the default identifier: MODELNAME-SERIAL (e.g.ALC- 3202D-71520).

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-404/1604).
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 Biamp 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 Biamp 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 Biamp-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 Biamp-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
NC.
The connections are available on the back panel via the 6-pin (ALC-3202) or 12-pin (ALC-404/1604) Phoenix connectors.
When the amplifier is in normal operating condition the NO contacts 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.

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 6 .
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 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 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. Zero-configuration 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: here.

Input Selection and Backup Policy
The “D” models allow two input signal sources per channel: analog and Dante® streams, whereas the “AN” models have a single input to allow only analog signals. ArmoníaPlus System Manager software provides an interface to select the input source.
Dual input models only: ALCs implement a backup policy aimed to improve reliability against signal fault. By assigning a bus priority to the 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 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.

Dead on Arrival (D.O.A.) Procedure
In case of a “dead on arrival” D.O.A. product, we ask the customer to contact the Biamp Service Department, mentioning the serial number of the faulty unit.
The D.O.A. unit will be replaced completely without any additional charges!

Important Note: To avoid any warranty issue, do NOT tamper with, or operate the D.O.A. unit in any way. Biamp declines any D.O.A. product warranty service if the returned unit has been tampered with or misused by the customer.
