OPERATING A SYSTEM INTEGRATED WITH A HOME THEATER
Operation from the Stereo Zones Provided by the A4.6Ci
User operation from the zones provided by A4.6Ci’s, are not affected when integrating a Home Theater to
share source components (see System Configurations 3 and 4). Solo™ or Select™ Master Keypad Modules in
each zone independently operate the zone to which they are dedicated (i.e., Zone ON/OFF, Volume
Up/Down, Mute). When a user in a zone from any A4.6Ci, presses a key/button, the IR commands required
for the shared source components (i.e., Power ON/OFF, Play, Stop and Channel Up) are issued by the A4.6Ci
that has been programmed. (See the Programming Section of this manual for specific details on programming.)
Operation from the Home Theater Zone
A Home Theater can be integrated to share source components with an A4.6Ci using one of three methods.
How the Home Theater will operate depends on which method is chosen. The three methods of integra-
tion are listed below, along with a description of the Home Theater operation they provide.
Method 1. Integrated Home Theater Using 12V Home Theater Sync and IR Repeating
The Home Theater IR Remote (programmed with the actual IR commands of the shared source com-
ponents) sends IR commands to the shared source components via the IR Input located on the rear panel
of the A4.6Ci. This enables control of the shared source components for users in the Home Theater. All
IR commands for shared source components are passed through to all four of the flasher outputs on the
rear panel of the A4.6Ci. Only discrete power ON and transport commands for the shared source com-
ponents should be issued.
Important Note: Because all of the actual IR commands for shared components are passed through to
all the flasher outputs simultaneously, identical source components cannot operate individually with this
method. Also, when using this method, reliable activation of shared source components that use a sin-
gle IR command for power ON/OFF is not possible. (Refer to Method 2 for operating identical shared
source components and components with a single IR command for power ON/OFF.)
When the Home Theater turns ON, it provides a 12V status signal that is connected to the Home Theater sync
input on the rear panel of the A4.6Ci. This provides the ON/OFF status of the Home Theater to the A4.6Ci.
The moment a valid Home Theater sync signal is present at the A4.6Ci, the A4.6Ci’s 12V control out-
put sends a turn-on trigger for a voltage-triggered AC power strip (i.e., Niles AC-3) to activate latching
source components.
When the Home Theater is turned OFF, the A4.6Ci checks itself and any other A4.6Ci’s in the system to
see if any zones are still ON. If all zones are OFF, the 12V control output shuts OFF, turning OFF the
latching source components. Power OFF IR commands for turning OFF the IR-controlled shared source
components also are issued.
Method 2. Integrated Home Theater Using 12V Home Theater Sync and Niles R-4 Commands
The Home Theater IR remote (programmed with the Niles R-4 IR commands) sends IR commands to the
A4.6Ci via the IR input on the rear panel. This enables control of the shared source components for users
in the Home Theater.
All the actual IR commands for shared source components are programmed into the A4.6Ci. When a
Niles IR command is received, the corresponding programmed source IR commands are sent to the
flasher output dedicated to the shared source component that is selected (i.e., Source 1 = Flasher 1,
Source 2 = Flasher 2, Source 3 = Flasher 3, Source 4 = Flasher 4). Identical source components can be
individually operated with this method.
Important Note: Shared source components that are unique in the system can have their actual IR com-
mands programmed into the Home Theater remote and issued for simple IR repeating with this method.
