Stereo Audio Input/Output Boards Specifications
Applies to stereo audio boards contained in the Optima SD systems listed on the previous page.
* Total of input gain plus output gain cannot 10 dB.
AMX reserves the right to modify its products and their specifications without notice.
Attaching Wires
When attaching stereo audio input and output wires, refer to the sheet labeled “AutoPatch Optima
Connector Guide” that shipped with the system. The sheet shows where to attach the wires on the rear of
each enclosure. Follow the sheet exactly; the system was programmed at the factory to operate only as
indicated on the sheet. For multi-enclosure systems, each enclosure will be numbered (e.g., “Chassis 1
of 2”) on a label located on the left side (near the power receptacle).
The input connectors are on the left side of each stereo audio board, and the output connectors are on the
right side. Input and output connectors are numbered separately. The number of stereo pair connectors
depends on the configuration.
