Introduction: Thank you for your purchase of a Knoll CI6 12 channel
controller amplifier and congratulations on your choice. The CI6 features six
deluxe digital volume controlled stereo amplifiers with individual seven source
selection. This is Knoll's fourth generation of multi-channel, high-quality
power amplifiers. The CI6 is designed to meet the amplifier needs of custom
installed multi-zone systems where high quality sound is a specific
requirement.
Each of the six zones or rooms can select any of the seven inputs, with
individual volume control, bass, treble and balance. Extras such as an
external voltage trigger that can turn source equipment on and off, individual
zone infrared outputs, a fully balanced paging override, RS232 control, fully
buffered line level outputs and many more features give the CI6 exceptional
value when installed in homes and large complex systems. Except for the
power button all controls are rear mounted. A data port is provided for
ganging multiple CI6's. Infrared signals can be relayed from the keypads to
the source equipment.
The CI6 is normally controlled by MR164 or MR166 long distance LCD
keypads with or without Knoll remote controls or RS232 commands from
whole house controllers. The paging override is normally used for whole
house announcements or doorbell chimes.

source selections, volumes, etc.
