Signal Mixing
This page is provided to configure input to output channel routing and AMM settings.
1. Route analog/digital input channels to each desired output in the signal mixer. By
default almost all input channels are sent to all output channels with these
exceptions; USBin is not routed to USBout, and VCin is not routed to VCout.
Mixing can be set individually for each output channel.
The AMM module will select microphones to open based on activity detected on each
them. Remove any microphones from the selection if they should never be used.
Note: The AMM detects if a microphone is not connected so there is no need to remove
unconnected microphones.
An active microphone(s) is displayed by an "ACTIVE" indicator for that channel as
shown.
2. Disable AMM by pressing the red AMM symbol. This causes all microphone signals
to be added.
Microphone Settings
Use the Microphone Settings page (FIG. 5) to configure the signal processing modules
that operate on the microphone signals.
1. Select 48 VDC phantom power on/off for each microphone.
2. Configure signal processing on each microphone channel as shown in below.
Basic Configuration
Most maintenance tasks like firmware upgrades, store and load settings and change
login credentials are performed in the Basic Configuration page.
Firmware Upgrade
1. Go to the AMX website and download the latest firmware package to the local
drive.
http://www.amx.com/products
2. From the Alero web interface, select the Basic Configuration page.
3. Click Choose File to select the new firmware file from the local computer. The
naming convention of new firmware releases is
firmware-package_yyyymmddhhmm.bin
4. When the new firmware is selected, press Upload to start the firmware upgrade.
Alero will update the firmware and restart. Settings will be stored and used in the
new firmware.
Note: The device will keep its current settings (including network) when upgraded.
Factory Reset
If somehow Alero has ended up in a bad state, there is an option to reset the device to
factory settings. Follow these steps for performing a factory reset.
1. Turn the Alero power OFF.
2. Press the Reset button on the rear panel for approximately 5 seconds while
powering Alero back ON.
3. Wait for Alero to start.
