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.
