The KPA series amplifiers have K8 input and link connections built in as a standard feature. A K8 digital audio
distribution line may be connected to the K8 IN connection on the rear of the amplifier via a standard Cat5-cable
terminated with an RJ-45 connector. The LINK connection may be used to daisy chain the K8 bus to the next
amplifier or other K8 device.
Channel selection is made using rotary switches behind the front panel of the amplifier. Any stereo pair of the
available 16 audio channels on the K8 bus may be selected. For example, channels 1&2, 3&4, etc. may be selected.
figure 7
The LED labelled “S” on the K8 connector indicates that a good K8 signal is present on the bus and the amplifier is
Synchronized to it.
The LED labelled “W” on the K8 connector is used to Wink, or flash on and off, to identify the amplifier when being
remote controlled in software.
The K8 TERM switches must all be set to ON when the amplifier is the last device in the K8 daisy chain. When the
LINK connection is in use, the termination must be set to OFF.
Please see the user manual for the K8 input devices for more extensive information on how to use and configure a
K8 bus. The KPA amplifier is compatible with any K8 input device including K8-AESI16 AES digital inputs,
K8-AI8 analog inputs and K8-ESB Ethersound bridge as well as new ones being offered in the future.
