GETTING STARTED
The Sonance UA 2-125 amplifier comes ready to play
audio out-of-the-box. Installers should set up the amp
using the SonARC interface (Bluetooth required) for
optimal performance. Sonance suggests the following
installation sequence:
1. The UA 2-125 amp should be away from moisture
and temperatures exceeding 100°F (38°C).
2. Mount the UA 2-125 using the included mounting
brackets or M3 T-Nuts. NOTE: If the mounting
position will make the BLE antenna inaccessible,
proceed with Steps 3 through 8 before mounting
in its final location.
3. Connect audio inputs: Analog RCA and/or Coax or
TOSLINK.
4. Connect speaker outputs.
5. Confirm source device (Analog RCA or Coax/
Toslink) is muted.
6. Power the UA 2-125 on by plugging the power
cord into an AC mains outlet.
7. Use the SonARC app on your phone to connect to
the UA 2-125 and configure settings as desired.
8. Unmute the source device.
9. Finalize mounting and cable management.

SOURCE CONNECTIONS
The UA 2-125 amplifier can
support multiple connections.
In the SonARC App, one
connection can be selected as
the default source, while the
other will be the secondary
source. Normally, audio will play
from the default source. If audio
is detected on the secondary
source, the UA 2-125 will automatically switch to the
secondary source. From the factory, the default source
for the UA 2-125 is the Analog RCA connections while
the Coax/TOSLINK connections are the secondary
source. If you are using a digital source (Coax or
TOSLINK), make sure that the source device is set up
to provide a 2-channel PCM signal.
NOTE: Use only one of the S/PDIF connections: Coax
or Toslink.
SETUP BUTTON
Bluetooth on the UA 2-125 should be on by default. If
the phone running the SonARC App cannot connect
with the UA 2-125 unit, press the SETUP button to
initiate the Bluetooth connection.
IR CONTROL
The IR 3.5mm jack can be used to receive IR
commands from a distribution box or provided sensor.
Refer to the UA 2-125 webpage for specific IR control
codes. This feature will turn on automatically when
the IR sensor is plugged in, and does not need to be
enabled in the SonARC App interface.
CLIP INDICATOR LED
When the amp is clipping, audio peaks display as RED
flashes. If this occurs, the amplifier is being overdriven
and the volume control needs to be reduced until the
peaks no longer cause the LED to illuminate.
