Quick Start
Mounting the Athena in the Rack
The Intelix Athena matrix mixer/amplifier mounts in a standard 19” width rack
and requires three rack spaces (3RU).
Ventilation
¾At least 2 inches of free air space is required on both sides of
the Athena matrix for proper side ventilation.
¾Ensure there are no closeable doors on the rack that might seal
the Athena matrix from a steady supply of cool air.
¾All Athena matrices are equipped with a front panel mounted
exhaust fan. The front of the Athena must not be obstructed.
¾Avoid mounting the Athena matrix near a power amplifier or
any other source of significant heat.
¾It is recommended that you leave an empty rack space above
and below the Athena matrix for additional cooling.

Connecting Audio Cabling to the Athena
Please follow the steps below when connecting audio cabling to the Athena
matrix.
1) Determine if the output from the source device (CD player,
microphone, receiver, etc.) to the Athena matrix is balanced or
unbalanced. If unsure, refer to device’s manual.
¾If the source device output is balanced, connect the device to
the Athena matrix using a modified cable with either an XLR
connector or a ¼” TRS (Tip Right Sleeve) connector.
¾If the source device output is unbalanced, connect the device
to the Athena matrix using a modified cable with an RCA
connector.
2) Once the cable and connecter style have been determined, modify the
cable by cutting off the connector on one end.
3) Strip back the main insulation of the cable 1/8”. Take care not to
damage the conductors inside the cable.
4) Separate the insulated conductors from the exposed outer strands.
5) Twist together the exposed strands into a single conductor.
6) Strip back the insulation of the internally insulated conductor 1/8”.
7) Twist exposed strands of each conductor into one tightly twisted
conductor. This will be the positive conductor or the plus and
negative phase of a balanced source.
8) Connect the twisted conductors to the Athena matrix via removable
screw-terminal (phoenix-type) connectors.
9) Repeat the above steps for each input source required.
Recommended Audio Cable Wiring Methods
Connecting an Unbalanced Source to a Balanced Input
1) Cut a piece of audio cable about 1” long.
2) Pull out the conductors from the cable and twist together so that
there is now a single 1” long conductor.
3) Bend and insert each end of 1” long conductor into terminals
(GND) and (-) of the Phoenix-type plug receptacles of the
Athena unit.
4) Insert positive twisted conductor into terminal (+) of the
phoenix-type plug receptacle.
5) Insert ground twisted conductor into terminal (+) of the
phoenix-type plug receptacle.

connect one end of the cable to the coaxial SPDIF (Sony
Phillips Digital Interface) connector on the source device.
2) Connect the other end of the coaxial cable to the SPDIF In 1 or
In 2 (In 1 uses audio input channels 1 and 2, and In 2 uses audio
input channels 5 and 6).
Note: The SPDIF inputs and outputs must be activated in the
Athena Designer Software.
Connecting 70 volt Speaker Outputs
For 70 volt systems, the Intelix 70V-AM transformer module must
be purchased separately. Each 70V-AM provides eight channels of
outputs. Two 70V-AM modules are required for an Athena-16
system.

Intelix Audisey Athena Installation Manual
10 www.intelix.com
Connecting Amplified Outputs
Each channel of the amplifier is a full-
b
ridge output configuration
consisting of a positive (+) and negative (-) output. The outputs
must remain floating and must not be connected to ground.
Note: The speaker outputs are full
y
protected a
g
ainst shorts
and over current conditions. A short to
g
round or over current
condition will cause the affected output channel to shut
down for five seconds. The amplifier will resume operation
automatically after removal of the short or over current
condition. An over temperature condition will cause the
amplifier to limit the output power gracefully. If temperature
rises over a critical point, the amplifier will shut down.
