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.
4. Tuner Presets – Press to program or select up to 10 AM or FM preset stations. 5. C-6 Controller Display – Backlit LCD provides information regarding: Tuner preset number, frequency, and mode. Also displays multiple screens for Controller Setup and programming modes.
24. AC Power – Standard IEC 3-conductor AC line cord receptacle. 25. AC Fuse – T8A L250 26. Main Power Switch – Turns AC power to the C-6 Controller ON/OFF. 27. Zone Keypad/Speaker Terminal – Six plug-in four terminal screw connector terminals for connecting K-8, K-22 Keypads and speakers in remote zones.

NOTE 2: Any Source IR commands programmed into the C-6 Controller for the Keypads will respond to button presses from the R-1 and do not need to be programmed twice. 50. Source Select Buttons - Press to select an Input on the C-6 Controller in a Zone. No programming required.
(CD, DVD, Satellite Receiver, VCR, etc) should also be installed at this location. The C-6 and source components can be placed on shelves in a wall unit in a media room, or rack mounted in a standard 19” rack mount system. Always provide convenient access for loading CDs and DVDs.

What this means is that the C-6 Controller with K-8 or K-22 Keypads can be used to upgrade an existing single-zone audio system with volume controls to a multi-source, multi-zone Keypad controlled A/V distribution system.

Audio – Use a quality audio cable from the telephone system line audio or paging output to the Page Audio IN on the C-6 Controller. Line level audio can typically be run up to about 50’. Anything beyond that should be run through an appropriate balanced line adaptor. Terminate with a quality gold plated RCA type male plug at the head end and terminate as appropriate for the paging device used.
1. Using four conductor stranded wire, strip approximately ¼” of insulation from each conductor. Twist the strands until tight. 2. Connect the bare wires to the plug-in four terminal screw connectors included with the C-6 accessories. Be sure to maintain proper polarity from the RIGHT+, CONTROL, COMMON and +LEFT terminals for each zone output.

Audio – Connect one RCA to RCA mono audio cable from a line level audio output on the telephone system or device to be used for paging to the PAGE AUDIO IN on the C-6 Controller. Video – Connect one RCA to RCA shielded video cable from a composite video output from a security camera or other video device to be displayed in PAGE mode to the PAGE VIDEO IN on the C-6 Controller.

PROGRAMMING C-6 Controller Setup Menu All system programming is done in the C-6 Controller using the C-6 Controller Setup Menu. No PC, no software. Other than ‘Group’ and zone treble, mid and bass adjustments, once the Controller has been programmed, the entire system is ready to go. If the system starts out in a...

15db in 1db increments from unity gain. To properly adjust trim, all sources must be connected to their appropriate inputs on the C-6 Controller. They must all be loaded with program material (Radio station, CD, DVD, Video Tape etc.) and playing.

15. Press Menu to return to the default Tuner Preset Window. Zone Sharing There are two modes for linking zones with the C-6. One is GROUP and the other is ZONE SHARING. Group is a temporary linking of active zones by source and volume. Zone Sharing has two options.

The C-6 Controller is programmed at the factory for system functions such as ON/OFF, Source Select, Volume UP/DOWN etc. To control the common source components, IR commands for those devices must be programmed into the C-6. This is a simple process that should only take a few minutes.

9. Test all commands on all buttons for all sources. Replace commands as needed. NOTE 1: The R-1 Remote that comes with the C-6 has Navigation buttons not found on the keypads. These buttons are programmed using the same steps as the keypads. (Press a button on the R-1, followed by a button press on the source remote for the IR command to be associated with that button.) Once familiar with the process, it may be easier to program all IR commands...

7. Test power commands by turning all zones OFF. All components should be OFF. (If not, manually turn them off.) 8. Turn ON a single zone. All sources should turn ON. 9. Make changes to ON/OFF locations under the power button for sources as needed. Macros (Version IR1.7 and up) For each of the 5 external inputs on the C6, there are 17 buttons on the keypad, and an additional 9 buttons on the remote control to which macro sequences can be assigned.
satellite remote to the number buttons on the C6, as these IR commands will be used in our macros. Step 2. Now that we have taught all the necessary IR commands to the C6 we can start to create the macro.

Each command must be terminated with a carriage return: <cr>. If an invalid command is sent, the C-6 will respond with ERR. If a valid command is sent, the C-6 will respond with OK unless it is a query type command, in which case the C-6 will respond with information. Every response from the C-6 is terminated with CR/LF.
