1. Connect an analog audio source, using the included 5-pin captive screw connector, to the AUDIO IN port.
Use the desired wiring conguration, on the previous page. Both balanced and unbalanced wiring are
supported.
2. Connect an analog audio output device, using the included 5-pin captive screw connector, to the LINE OUT
port. Use the desired wiring conguration, on the previous page. Both balanced and unbalanced wiring are
supported.
3. Determine the use-case scenario of the AT-GAIN-120. The AT-GAIN-120 can be congured as either one of the
following. Only one type of speaker connection is permitted at a time.
• Distributed speaker system (high impedance)
Set the MODE switch to the required voltage setting: 70V or 100V. This mode is used for commercial
applications and longer speaker cable runs.
• Program speakers / stereo (low impedance)
Set the MODE switch to the impedance setting of the speakers being connected: 4Ω or 8Ω.
This mode is used for consumer applications and shorter speaker cable runs.

4. Connect the speakers to the proper port on the AT-GAIN-120, based on the selection made in the previous step.
5. Set the MODE switch to the proper setting, based on the type of speaker connection that is being used.
6. Connect the LAN port to a network switch for set up and control of the unit.
7. OPTIONAL: Connect the included 2-pin captive screw connector from the TRIGGER port to an automation
control system.
8. Connect the included IEC power cord to the power receptacle.
9. Connect the IEC power cable to an available electrical outlet.
The AT-GAIN-120 can be used with an optional network audio card, which supports Dante and AES76 audio streams.
If this card will be installed, refer to Network Audio Card Installation (page 40) for more information before
continuing with the following instructions. This network card is sold separately and is available from Atlona.
NOTE: Analog or NET audio (with optional card), are selectable from the web GUI, Atlona
Velocity™, or thrid-party control using the API. Refer to the Stereo / Mono Audio Power Amplifer
120 Watts Application Programming Interface, on the Atlona web site for more information.
In addtion, the LINE OUT port only outputs analog audio. This port cannot be used to output
digital audio from the optional AT-GAIN-NET card.
