  • Page 23: Component Compatibility

    COMPONENT COMPATIBILITY INFRARED COMMAND COMPATIBILITY IR control testing was conducted on many equipment brands to determine their compatibility with the A4.6Ci. Typical A/V source components (i.e., CD, DVD, DSS, Cable Boxes, etc.) from each brand were chosen for the test. All brands listed below passed the test.

  • Page 24: Source-Power Synchronization

    OFF, and to turn them OFF if they are ON. It is necessary to “synchronize” these source components with the A4.6Ci so it knows not to send an ON command if the source components are already ON (if it did, the source components would turn OFF, which is not the desired result).

  • Page 25: Choosing A Synchronization Method

    The A4.6Ci has three 12V Video Sync connections for synchronizing as many as three source components. In Figure 18, the video output of a DSS is connected to both a TV and the corresponding sync input for the DSS using an RCA Y-adapter.
  • Page 26 AC power plug is connected to the current sensing outlet on the APC-2. The APC-2’s 12V DC output is connect- ed to the A4.6Ci’s sync input dedicated to the CD changer, using a Niles 10’ bare wire to mini-plug accessory cable (FG00724, see Accessories for more details).

  • Page 27: Source And Home Theater Sync Status

    The Niles LS-1 Light Sensor can synchronize a component by sensing changes in light. The 12V output of the LS-1 is then connected to the A4.6Ci’s sync input dedicated for that component. A mini- plug to RCA adapter is required for this connection (see Connections for more information).

  • Page 28: Operational Overview

    MASTER KEYS/SOURCE BUTTONS The Master Keys available on the Solo hand-held R-4 Remote accessory (Figure 21) provide "one-touch activation" of the A4.6Ci and its connected source components. The Master Keys on the Solo and Select Master Keypad Modules are equipped with back-lit LEDs for indicat- ing Zone ON/OFF, Zone Mute, and Zone Input Selection status.

    It is typically used for issuing a stop command to latching source components that automatically play when powered. Note: Only the A4.6Ci set as the Master executes the System ON Sequence. Event 6 The Master Key Sequence is executed last and is programmed with IR commands and/or delays.

  • Page 30: Master Key/Source Button Operation

    OPERATIONAL OVERVIEW MASTER KEY/SOURCE BUTTON OPERATION The Master Key/Source Buttons have two methods for operating the system. Single-Zone Operation The first method, a quick tap of a Master Key/Source Button in a zone (holding the key/button for less than three seconds), causes only that zone to turn ON.

  • Page 31: Off Key Events

    OPERATIONAL OVERVIEW OFF KEY EVENTS When you press the OFF Key/Button, up to four events may occur. The first event is the Zone OFF sequence programmed by the installer for the zone that is turning OFF. The second event is factory programmed and turns the zone or all zones OFF every time the OFF Key/Button is pressed.

  • Page 35: Identical Source Components

    A source component in an A4.6Ci multi-zone system is considered “shared” when its audio signal is connect- ed to more than one A4.6Ci or if it is connected to an A4.6Ci and a Home Theater system (refer to System Configuration 2 and System Configuration 3 for more details).

  • Page 36: Operation From The Stereo Zones Provided By The A4.6Ci

    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.

  • Page 37: System Busy Indication

    The A4.6Ci has a built-in paging-indication mode that is displayed on a Master Key LED of the Solo Keypad Module. If the A4.6Ci sends a page to a zone, the user is alerted by the Master Key. That Master Key LED will blink slowly GREEN.

  • Page 38: Installation

    PLACEMENT Place the A4.6Ci on a flat, level surface such as a table or shelf, with its weight equally distributed on each of its four feet. Like any high-fidelity component, the A4.6Ci will last much longer if it receives adequate ventilation for proper cooling (see Figure 28).

  • Page 39: Connections

    CONNECTIONS TERMINATING FOUR-PAIR TWISTED CABLE The Solo and Select Master Keypad Modules, the expander, and the A4.6Ci’s system-expansion connections ™ ™ require a four-pair twisted cable with a one-to-one wiring configuration. To maintain consistency throughout all Intellipad ® Ci installations, we recommend the color-coding pattern described in Figure 31. However, you may follow the color-coding pattern of your choice, as long as it is consistent throughout the system.

  • Page 40: Connecting Ir Sensors

    CONNECTIONS CONNECTING IR SENSORS An IR sensor can be connected to a Solo Select ™ Master Keypad Module in one of two ways, directly with a four-pair twisted cable (see Figure 34 and 35), or with a three-wire to RJ-45 adapter available from Niles for IR sen- sors installed with two-conductor shielded cable.
