C-6 INSTALLATION INSTRUCTIONS
INTRODUCTION
Welcome to Nexus Audio Systems and congratulations on your purchase of the C-6 Multi-Room
Audio/Video System. The C-6 is a multi-zone controller that supports 6 independently operated
zones as well as 5 external audio/video source components in addition to a built in AM/FM Tuner
module. Engineered for the future, the unit includes a RS-232 Serial Port and a “Feature” Port for
future advanced control capabilities. This means that your system can easily be integrated with
other home automation systems. The Nexus C-6 provides paging capability and a mute function
that can integrate with your doorbell or telephone system to ensure you will not miss that
important call or visitor.
The system is expandable to 18 zones using the X-1 and X-2 Expansion Controllers. The K-8 and
K-22 Keypads provide simple, intuitive control. Both models control Zone Power, Source
Selection, Source Control, Volume, Treble and Bass. With an easy to read backlit LCD, there is
never any question to the user of system status, the source selected, or volume. The K-22
provides the additional flexibility of direct tuning, disc and track selection. In Group Mode, the K-
22 Keypad can scroll and display configurable zone names to aid in setting up groups for
temporary ‘Party Mode’ configurations. Both Keypads feature an Infrared receiver that can be
used with the R-1 Handheld Remote for additional flexibility and armchair control.
The greatest feature of the C-6 is its ‘Phantom Control’ Technology. The C-6 requires no special
control wiring by integrating easily onto the same 4 wires used to drive the speakers. This makes
the C-6 the perfect choice for any installation. With new or existing construction, the C-6 provides
the greatest flexibility, ease of operation and simplicity of installation of any multi-room product on
the market today.
