Connection Instructions
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 configuration, on
the previous page.
2.
Determine the use-case scenario of the AT-GAIN-60. The AT-GAIN-60 can be configured 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:
24
,
70
, 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 13)
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
DC28V
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.
