4. AmpLink Connection
If you are using a Bose AmpLink-enabled amplifier, connect the AmpLink port (RJ-45) on
the EX-1280, EX-440C, or EX-1280C to the amplifier's AmpLink port using a shielded
Cat 5 cable.
CAUTION: Shielded EIA/TIA 568B straight Cat 5 cable, or equivalent, is required for proper
AmpLink operation. Unshielded cable is not supported and may cause AmpLink audio to
operate improperly.
The EX-440C transmits on the first four AmpLink channels. The EX-1280 and EX-1280C
transmit on the first eight AmpLink channels. Select the corresponding channels on the
amplifier using the amplifier's rear-panel switch settings.
