line level speaker signal outputs.
DESCRIPTION USAGE
Front Panel LED Indicators
Power A continuously lit LED Indicates that the unit is powered on.
Microphones SIGNAL - A continuously lit LED indicates an active signal on the
corresponding microphone channel.
CLIP - Indicates risk of amplitude clipping on corresponding
microphone channel due to a strong signal. LED is only active for a short
time after a strong signal is detected. Reduce gain on the channel if LED
is active.
Rear Panel Connectors

LINE IN 2 analog line level inputs
LINE OUT 2 analog line level outputs
PA 2 mono speaker channel outputs. Line level
Microphones 8 microphone inputs. Line level/phantom power configurable.
Mute Muting of certain microphone groups.
Reset • Press more than 1 second to set the IP settings to DHCP. See Detect
IP Address section on page 1.
• Press less than 1 second to return the IP settings to a Static address
of 192.168.1.2.
• Press while powering unit "ON" to Return to factory settings. See
Factory Reset section on page 2.
USB Audio input/output.
LAN 10/100 Configuration of unit via network. The port has L/A (Link Activity) and
SPD (Speed) LEDs. The L/A flashes indicating traffic, otherwise is off.
The SPD LED is on by default when a network link is established.
12 V Power supply input, 12 V
Installation
Follow these steps which represent a typical installation procedure:
Physical Connections
1. Connect audio input and output channels to rear panel, including microphones,
using the included screw terminal Phoenix type connectors (FIG. 1). Refer to the
wire guide on the back panel.

2. Connect standard network cable for device configuration to the LAN 10/100 port.
3. Connect the power supply to PWR connector. Device will power on automatically.
Detect IP Address
1. Ensure Alero is powered on and connected to a network with an Ethernet cable.
2. In factory settings, the IP address is static (192.168.1.2). If DHCP is preferred
press the reset button for more than 1 second to enable it. Pressing Reset for less
than one second will return the unit back to its static IP address.
3. Locate all devices on network using zero configuration networking (zeroconf). If
there are more than one devices in the list, determine the IP of the current unit by
powering it off and observing which device disappears from the zeroconf utility.
Note: You may also locate a new Alero on a network using the default hostname by
entering the URL http://alero-aec-8.local
with securing screw terminals.

Configuration
Access the Configuration Page
1. Open a web browser
2. Enter the IP address for the device. Default login credentials are:
Username: admin
Password: admin
The configuration page is designed with a dashboard where the most relevant settings
can be adjusted. There are also five configuration pages:
PAGE TASKS
Basic Configuration Perform maintenance tasks like firmware upgrades, store and
load settings and change login credentials.
Network Configuration Configure network settings and enable DHCP
Levels Current audio signal levels for all input and output channels.
Signal Mixing Set or disabled AMM (Auto Mic Mixer) individually for each
output channel, configure input to output channel routing.
Microphone Settings Configure signal processing modules on the microphone
signals and set 48 VDC phantom power to microphones is
needed.
Network Configuration
DHCP can be disabled and network settings entered manually here. See Figure 2.
Note: If the manual settings are bad, the device w ill not be accessible via a
configuration page since the network connection will not work. If this happen, perform a
factory reset.

Levels
This page (FIG. 3) provides an overview of current audio signal levels for all input and
output channels. All input and output signal levels can be adjusted with configurable
digital gain levels. It is also possible to adjust an analog gain for the analog input
signals.
1. Monitor signal amplitude on input channels and adjust gain if necessary.
2. Monitor signal amplitude on output channels and adjust gain if necessary.
