Package Contents
The Atlona Gain™ 60 (AT-GAIN-60)is a compact power amplier designed for low or high
impedance applications. A mode selector switch allows the Gain 60 to deliver two channels
of 30 watts each into 4 or 8 ohms, or a single channel of 60 watts at 24, 70,or 100 volts.
This Class-D amplier is energy ecient and convection-cooled without the need for fans.
Additionally, the Gain 60 is UL 2043 plenum-rated, allowing convenient yet discreet installation
in a plenum airspace above a drop ceiling. Selectable balanced captive screw and unbalanced
RCA inputs are provided for system design versatility. The Gain 60 is controllable via TCP/
IP or RS-232, and can be integrated with Atlona AV switchers, HDBaseT™ receivers, and
OmniStream™ AV decoders and audio devices for a wide variety of sound reinforcement
applications.

The AT-GAIN-60 provides RS-232 control between an automation system and an RS-232 device.
This step is optional.
1. Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND wires.
3. Insert the TX, RX, and GND wires into correct terminal on the included captive screw block.

The AUDIO IN 1 connector on the AT-GAIN-60 provides the ability to connect either balanced or
unbalanced audio inputs, using the included 5-pin captive screw block.
Balanced audio connections use two signal wires and a ground to minimize interference in audio
signals. Unbalanced audio connections use one signal wire and a ground and are used if system
components don’t support balanced signals.

Installation Guide
AT-GAIN-60
Installation
1. Connect an analog audio source to the AUDIO IN ports. Once connected, press the INPUT
button on the front panel, to switch between the RCA and the 5-pin captive screw port.
• RCA cables (unbalanced)
Connect shielded RCA-type cables from the audio source to the AUDIO IN 2 left/right
RCA jacks.
• Balanced/Unbalanced
Connect the included 5-pin captive screw to the AUDIO IN 1 port. Use the desired
wiring conguration, on the previous page.
2. Determine the use-case scenario of the AT-GAIN-60. The AT-GAIN-60 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 OUTPUT MODE switch to the required voltage setting: 24V, 70V, or 100V.
This mode is used for commercial applications and longer speaker cable runs.
• Program speakers / stereo (low impedance)
Set the OUTPUT 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.
Refer to Connection Diagrams (page 7) for example applications.
3. Connect the speakers to the proper port on the AT-GAIN-60, based on the selection made
in the previous step.
4. Connect the LAN port to a network switch for set up and control of the unit.
5. Connect the included power supply to the DC 28V power receptacle.
6. Connect the IEC power cable to an available electrical outlet.
NOTE: The AT-GAIN-60 only supports one type of speaker connection at a time:
high-impedance or low-impedance.

IP Conguration
By default, the AT-GAIN-60 is set to DHCP mode, allowing a DHCP server (if present) to assign
the unit an IP address.
Press and hold the INPUT button for approximately 10 seconds. Release the button once both
input LED indicators 1and 2 begin to ash. The number of ashes will indicate the currently
selected IP mode:
