Overview

The K8-AI8 is a K8 input device allowing 8 analogue audio channels to be placed onto the K8 bus.

Stacking Input Devices

Two AI8 devices may be stacked to populate all 16 available audio channels. Alternately, the AI8 may be
combined with any other 8 channel input device for a total of 16 channels.
Using a crossover cable connect the Out 2 of the first device to the K8 Out 1 of the second device. The K8
Out 1 of the first device is then used to drive the K8 bus.

Termination Setting

The 4 termination switches must all be set to "on" when the AI8 is the first device in the K8 chain.
Both K8 output ports connected:
One K8 output port connected:

Control and Monitoring
