INTRODUCTION

Niles Audio has recognized the need for a simple-to-use,cost-effective,and flexiblemulti-zonesystem that can provide years of listening pleasure tomusic-lovers.Our engineering andproduct-developmentdepartments have joined forces to produce an innovativemulti-zonepreamplifier that incorporates six separate zones and connections for four audio source components.

The A4.6Ci MultiZone Preamplifier is the multi-zonesolution you have been asking for. It allows you to combine Keypad Modules with Infrared Sensors andHand-HeldRemotes for total control of your Home Entertainment System, providing"one-touch"system-widecontrol.

Now everyone in the household can be happy: One person can listen to the CD player in a bedroom, while another simultaneously listens to the radio by the pool. At the same time a third person can listen to DSS music in the den. In addition, the A4.6Ci's source-componentIR control iscustom-programmableto provide intuitive operation for a wide range of source components.

The Niles A4.6Ci MultiZone Preamplifier

FEATURES AND BENEFITS

Multi-zone/Multi-source

The A4.6Ci MultiZone Preamplifier incorporates matrix preamplifier technology to provide as many as four source components to six listening zones simultaneously. Finally, Dad can relax to the sound of his favorite music in the den while the kids are listening to their favorite music by the pool.

Central Intelligence

The design approach of the A4.6Ci MultiZone Preamplifier is a radical departure from that of traditional programmable keypad-controlledmulti-zonesystems. Instead of redundantly programming each of the individual keypads with IR commands, all IR commands are programmed and stored in the A4.6Ci. The Soloand SelectMaster Keypad Modules, Numericand TransportAccessory Keypad Modules, and Niles IR Sensors connect to the A4.6Ci for complete system control.

Total system cost can be dramatically reduced due to shorter programming time and the low cost of the modular keypads located in each zone.

Quick and Easy Programming with PC Archiving

Manual programming is quick and easy, with push buttons and LED visual prompts that lead you step by step through the programming process. Additionally, with Niles Ci Archiving software, all system programming can be archived on your PC for back-upand for use withpre-designedsystems.

One-TouchOperation Including System and Component Power Synchronization

One touch of a Master Key on an IntelliPad® Ci Soloor SelectMaster Keypad Module tells the A4.6Ci Preamplifier to perform an intelligent sequence of IR commands for complete control of your distributed A/V system.

Sync Inputs provided by the A4.6Ci sense wether the connected source components are ON or OFF. Power commands for these source components are issued only if the source components are actually OFF, turning them on correctly, every time. The proper input for the source component is then selected and a programmed sequence of IR commands is issued (i.e., play or favorite station).

A complex mix of various brand audio/video components can be operated with ease and simplicity when using the A4.6Ci.

Elegant and Intuitive User Interfaces

The SoloMaster Keypad Module - The Solo Master Keypad Module is an elegant,single-gang,complete-controlsolution for the A4.6Ci. Fourcustom-labeledMaster Keys provide complete system activation, source selection, and source play commands, while a complete set of cursor keys provides basic source transport and menu control.

The SelectMaster Keypad Module - The Select Master Keypad Module is an advanced control solution for the A4.6Ci. Eightcustom-labeledMaster Keys provide complete system activation, source selection, and source play/customized music selections.

The NumericAccessory Keypad Module - The Numeric Accessory Keypad Module can be included along with the Solo and Select Master Keypad Module in any or all zones. It provides direct access to discs, tracks, stations, and channels when operating DSS receivers, and CD/DVD changers.

The TransportAccessory Keypad Module - The TransportAccessory Keypad Module can be included along with the Soloand SelectMaster Keypad Module in any or all zones. It provides basic transport functions and menu cursor keys for detailed control of source components.

FEATURES AND BENEFITS

The R-4 Remote - TheR-4Remote provides system control via an ergonomichand-heldIR remote control. Zones that have been installed with Niles IR Sensors can take advantage of theR-4Remote, providing system control from anywhere in the room.

System-WideOperation

The A4.6Ci MultiZone Preamplifier incorporates system-widecontrol to activate all zones to a particular source component. An ALL OFF command is also included for complete system shutdown from any zone in the system.

Paging Input for Telephone Systems

A paging input is provided for telephone systems equipped with a paging output. Audio sensing is utilized to detect the paging signal. Source components currently playing in the various zones are interrupted, enabling the paging signal to play through. If a zone is off during a page, it turns on, enabling the paging signal to play through. Front-panelswitches are provided to disable this paging feature in any zones where it is not required.

12V Control Output

A control-outputconnector provides a constant 12V DC trigger signal the moment any zone is activated. This signal can be interfaced tovoltage-triggeredAC power strips (i.e., NilesAC-3)for the automation of source components that can only be activated via switched AC outlets.

Expandable for Larger Multi Zone Systems

Up to four A4.6Ci’s can be combined in a single system, providing 24 zones. Source component audio signals are shared between preamplifiers, utilizing the buffered cascade audio outputs provided for each source component.

Multiple Rooms in a Single Zone

A single zone of an A4.6Ci can be expanded to accommodate as many as six individual rooms (master-bedroomsuites, outdoor areas, etc.). A Niles Ci Silencer Muting Volume Control (White - FG00773, Almond - FG00774, Bone – FG00776) located in each room/area in the zone along with a Master Keypad Module (Solo or Select) provides individual ON/OFF and volume adjustment. A Niles Ci Expander (FG00853) connects all keypads to a single zone of the A4.6Ci preamplifier. As many as 36 rooms can be connected to a single A4.6Ci preamplifier using six Ci expanders and 36 Ci silencer volume controls.

Program Memory Protection

The A4.6Ci MultiZone Preamplifier utilizes non-volatilememory for storage of its programming. This safeguards against accidental loss of the programming for the entire life of the product.

This is the simplest of the A4.6Ci configurations (see Figure 7). It depicts one Niles A4.6Ci MultiZone Preamplifier installed to provide sound to six listening zones.

Each zone consists of one room with one pair of speakers. One SoloMaster Keypad Moduleor one SelectMaster Keypad Module is included in each zone for user control. NumericAccessory Keypad Modules and/or TransportAccessory Keypad Modules and IR Sensors are added to specific zones as options.

Source Components

The A4.6Ci has RCA audio inputs for connecting four external source components for selection by each of the six zones.

With this configuration, a user in one zone can listen to one source component while another user in a different zone listens to a different source component (i.e., the CD can be selected in Zone 1 while the tuner is selected in Zone 2). Additionally, each of the six zones can be set to an individual volume level. If more than one zone chooses the same source component, IR control of that source component is shared between the zones.

13

SYSTEM CONFIGURATIONS

Keypads and IR Sensors

Keypads and IR sensors enable the user to control the Niles A4.6Ci MultiZone Preamplifier and its connected source components. The source components’ IR commands are programmed into the Niles A4.6Ci MultiZone Preamplifier. These commands are then triggered when the user presses a keypad button or issues a Niles IR command to an IR sensor.

Each zone on the A4.6Ci has a corresponding RJ-45keypad connector that is used to connect one Solo™ or Select™ Master Keypad Module. Each Master Keypad Module can be mated with one optional Numeric™ or Transport™ Accessory Keypad Module using an included jumper cable (see Connections). The Solo™ or Select™ Master Keypad Modules connect to the A4.6Ci with a "home run" offour-pairtwisted cable, terminated withRJ-45connectors.

An IR Sensor can be included in any zone and connects directly to the Soloor SelectMaster Keypad Module (see the Connections section of this manual for more details). Athree-wiretoRJ-45adapter is available from Niles (see Accessories) for IR Sensors installed withtwo-conductorshielded cable rather thanfour-pairtwisted cable.

Adding an IR Sensor enables the Niles R-4Accessoryhand-heldIR remote, or a learning remote control programmed with NilesR-4IR commands, to control the A4.6Ci and the connected source components. In addition, a source component’s actual IR commands (i.e., provided by the component’s original remote control or a learning remote control programmed with these IR commands) can be used with the IR sensor to control the source components.

Important Note: The A4.6Ci does not provide individual operation of identical source components when using a source component’s factory remote through an IR Sensor (see Identical Source Components on page 35 for more details).

Source-ComponentAutomation

There are two methods of controlling the power ON/OFF of the source components.

1. Synchronized IR - In Figure 4, the DSS receiver’s power ON/OFF is synchronized via a video signal connected to the A4.6Ci. When the Master Key/Source Button for the DSS is pressed, the A4.6Ci checks for a video signal at the Sync Input corresponding to the DSS.The A4.6Ci issues the power command to turn the

DSS ON only when no video signal is present and the DSS is OFF.

When the Off Key/Button is pressed in a zone, the A4.6Ci checks to see if any other zones are on (including the Home Theater zone sharing sources). The power command for turning the DSS OFF is issued only if that zone is the last zone turning OFF in entire system and a video signal is present at the Sync Input corresponding to the DSS.

Important Note: RCA Sync Inputs also can detect 12V for use with Niles external sensing devices, (i.e., theLS-1Light Sensor and theAPC-2Current Sensing Device). See Source Power Synchronization on page 41 for more information.

2. Latching Power - In Figure 4, AC power to the DVD and CD changer is turned on and off via the switched AC outlets of a NilesAC-3.TheAC-3is activated by the 12V control output of the A4.6Ci when any one of the six zones is ON (including the Home Theater Zone sharing sources).

Each Master Key on the Soloand SelectMaster Keypad Modules is programmable with a sequence of IR commands for their respective source component. Commands included in the sequence are typically the Play or Channel commands to start a source playing or to select a particular music or radio station after the source has been selected.

Flasher Outputs

Niles IRC-2PMicroFlashersconnect to the numbered flasher outputs on the rear panel of the Niles A4.6Ci MultiZone Preamplifier.Flashers send IR commands to the individual source components for control. AnIRC-1PFlooding Flasher can be connected to Flasher #4 to control more than one source component.

SYSTEM CONFIGURATIONS

CONFIGURATION 2 – ADDING ZONES USING MULTIPLE A4.6Ci’s

More than one A4.6Ci MultiZone Preamplifier can be used if the system requires more than six zones. A maximum of four A4.6Ci’s (providing up to 24 zones) can be combined to create a larger multi-zone/multi-sourcesystem. One A4.6Ci is designated as the Master and the others as Slaves (see Installation Settings on page 65 for more details).

Figure 8

In Figure 8, a four-pairtwisted cable connecting the CiNet system expansion ports of the two A4.6Ci’s facilitates communication between the two. This communication enables all zones, provided by both A4.6Ci’s, to obtain control of the shared source components (which are always connected to the Master). Also,system-widecommands can be issued from any zone (i.e., All Zones ON/OFF).

Sharing Source Components with Multiple A4.6Ci’s

The Niles A4.6Ci MultiZone Preamplifiers share the audio signal from the source components via the buffered cascade audio outputs provided, one for each of the four audio inputs.

Source-componentcontrol is accomplished via the programming in the Master A4.6Ci. All Slave A4.6Ci’s in the system are left unprogrammedexcept for Zone On/Off Sequences and the required function key IR programming to create these sequences.

All Flasher and Sync Input connections for the shared source components are made to the Master A4.6Ci. Keypad/Source Button commands and zone On/Off status are communicated to the Master A4.6Ci using the CiNet system expansion in/out connections, providing coordinated control of all source components.
