Alero ALR-AMP-8 8 Zone Power Amplifier Alero ALR-AMP-8 8 Zone Power Amplifier Overview The Alero ALR-AMP-8 8-Zone Power Amplifier (FG1104-01) features 16 distribution channels of true audiophile quality sound and highly efficient, heat-dissipating Class D power amplification – all smartly designed to fit into a compact 1RU chassis. Alero perfectly complements the AMX Precis DSP for a completely unified, whole-home distributed audio source switching and amplification solution.

Alero ALR-AMP-8 8 Zone Power Amplifier Front Panel Components (LEDs) The front panel features three LEDs (see FIG. 1 on page 1): POWER LED (Green/Red) The Power LED indicates that the current power state of the amp: Green indicates that the amplifier is On. Red indicates that the amplifier is receiving power, but is in Standby mode.

Installation Installation Mounting the Alero into an Equipment Rack The Alero ALR-AMP-8 can be mounted in a 19" equipment rack or on a solid flat surface. Use the included removable rack ears and removable feet for mounting. Ventilation The maximum operating ambient temperature is 45°C (113°F). To ensure that the rack enclosure is adequately ventilated, there must be a minimum of 3" all around the Alero unit.
Installation Audio (Signal) Inputs The following table provides pinout information for the Audio Inputs: Audio Input Connectors - Pinout Information PIN Function Description Type 1 Signal + Single Ended Signal Positive Input 2 Signal GND Single Ended Signal GND GND SE/BTL (Stereo/Bridge Mode) Switches (1-8) The ALR-AMP-8 features eight SE/BTL slide switches (located between the two RCA/phono input connectors for each Zone - see FIG. 4).
Installation Connecting Input Devices in Bridge Mode In Bridge Mode, input devices connect to the left input channels only. Note that left input connectors are white, and are the odd-numbered channels (CH1, 3, 5, 7, 9, 11, 13 and 15). There is a direct correlation between the audio inputs and the speaker outputs. For example, a bridged device connected to the Channel 1 input (CH1) will output on the CH1 (left) and CH2 (right) speaker outputs - see FIG.
Installation For wiring runs longer than 80 feet, 14-gauge speaker wire is recommended. Speaker Output Connectors The speaker output connectors consist of two 16 pin captive-wire terminals; each of the output terminals having a "+" and "- " terminal. The label "BTL" on each speaker pair points to the pins that are used when connecting a single speaker to an input in Bridge Mode (see SE/BTL (Stereo/Bridge Mode) Switches (1-8) on page 6).
Installation The table below illustrates the direct correlation between the audio inputs and the speaker outputs in Stereo Mode: Audio Inputs to Speaker Outputs - Stereo Mode Zone Audio Input Connectors Speaker Output Connectors 1 CH1 (left) / CH2 (right) CH1 (left) / CH2 (right) 2 CH3 (left) / CH4 (right) CH3 (left) / CH4 (right) 3 CH5 (left) / CH6 (right) CH5 (left) / CH6 (right) 4 CH7 (left) / CH8 (right) CH7 (left) / CH8 (right) 5 CH9 (left) / CH10 (right) CH9 (left) / CH10 (right) 6
Installation See Also: Connecting Input Devices in Bridge Mode on page 7. I/O (Control Input) Port The 10-pin captive-wire I/O (Control Input) port is for external control and status indication (FIG. 10). FIG.
Installation External Signal Sense Switch With the External Signal Sense switch in the ON position (see FIG. 10), the amplifier is automatically turned on when an audio signal is present, and automatically placed in standby mode when no audio signal has been present on the signal terminals for approximately 13 minutes. Note that the example diagram in FIG. 11 indicates the Signal Sense connection tied to the Left output from the source device, but Signal Sense can come from either output.
Installation Pin 3 and Pin 4 are hardwired together. Therefore, when a trigger is applied to pin 3 it will also be present at pin 4. Pin 4 will be high only if a signal is applied to Pin 3. Pin 5 - Local/Trigger GND Pin 5 on the 10-pin I/O port provides a ground connection for the 3-5V Logic Level Trigger. Pin 5 connects to the GND pin of an I/O port on an external controller, such as a NetLinx Central Controller.
Installation See page 16 for a NetLinx code example that illustrates configuring the port (on an NI-3100 NetLinx Central Controller) to properly monitor inputs from the On Signal, OC and Thermal functions. Pin 9 - On Signal Output / 12V Trigger On Signal Output Pin 9 on the 10-pin I/O port provides a continuous 12VDC when the Alero exits Standby Mode for On. When the Alero is in Standby mode, Pin 9 falls to zero.
Installation See page 16 for a NetLinx code example that illustrates configuring the port (on an NI-3100 NetLinx Central Controller) to properly monitor inputs from the On Signal, OC and Thermal functions. Pin 10 - Status GND Pin 10 on the 10-pin I/O port provides a ground reference for the Output pins (7-9), and is required for any device that needs to sense the potential. Pin 10 connects to the GND pin of an I/O port on an external controller, such as a NetLinx Central Controller (see FIG. 16).
Installation Applying Power to the Alero Amplifier This unit should only have one source of incoming power. Using more than one source of power to the Alero can result in damage to the internal components and a possible burn out. Apply power to the unit only after installation is complete.
Installation NetLinx Programming Example: On Signal, OC and Thermal Functions The following NetLinx code example illustrates configuring the port (on an NI-3100 NetLinx Central Controller) to properly monitor inputs from the On Signal, OC and Thermal functions: DEFINE_DEVICE dvIO = 5001:17:0 // I/O port on an NI-3100 DEFINE_EVENT DATA_EVENT[dvIO] { ONLINE: { SEND_COMMAND dvIO,'SET INPUT 1 HIGH' //SENSE ACTIVE HIGH (See Tech Note 777 for wiring instructions) SEND_COMMAND dvIO,'SET INPUT 2 LOW' //SENSE ACTIV
