INTRODUCTION
Niles Audio has recognized the need for a simple-to-use, cost-effective, and flexible multi-zone system that can provide years of listening pleasure to music-lovers. Our engineering and product-development departments have joined forces to produce an innovative multi-zone preamplifier that incorporates six separate zones and connections for four audio source components.
The A4.6Ci MultiZone Preamplifier is the multi-zone solution you have been asking for. It allows you to combine Keypad Modules with Infrared Sensors and Hand-Held Remotes for total control of your Home Entertainment System, providing "one-touch" system-wide control.
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-component IR control is custom-programmable to provide intuitive operation for a wide range of source components.

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-controlled multi-zone systems. Instead of redundantly programming each of the individual keypads with IR commands, all IR commands are programmed and stored in the A4.6Ci. The Solo™ and Select™ Master Keypad Modules, Numeric™ and Transport™ Accessory 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-up and for use with pre-designed systems.
One-Touch Operation Including System and Component Power Synchronization
One touch of a Master Key on an IntelliPad® Ci Solo™ or Select™ Master 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 Solo™ Master Keypad Module - The Solo Master Keypad Module is an elegant, single-gang, complete-control solution for the A4.6Ci. Four custom-labeled Master 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 Select™ Master Keypad Module - The Select Master Keypad Module is an advanced control solution for the A4.6Ci. Eight custom-labeled Master Keys provide complete system activation, source selection, and source play/customized music selections.
The Numeric™ Accessory 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 Transport™ Accessory Keypad Module - The Transport™ Accessory Keypad Module can be included along with the Solo™ and Select™ Master 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 - The R-4 Remote provides system control via an ergonomic hand-held IR remote control. Zones that have been installed with Niles IR Sensors can take advantage of the R-4 Remote, providing system control from anywhere in the room.
System-Wide Operation
The A4.6Ci MultiZone Preamplifier incorporates system-wide control 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-panel switches are provided to disable this paging feature in any zones where it is not required.
12V Control Output
A control-output connector provides a constant 12V DC trigger signal the moment any zone is activated. This signal can be interfaced to voltage-triggered AC power strips (i.e., Niles AC-3) for the automation of source components that can only be activated via switched AC outlets.

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-bedroom suites, 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-volatile memory 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 Solo™ Master Keypad Module or one Select™ Master Keypad Module is included in each zone for user control. Numeric™ Accessory Keypad Modules and/or Transport™ Accessory 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-45 keypad 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" of four-pair twisted cable, terminated with RJ-45 connectors.
An IR Sensor can be included in any zone and connects directly to the Solo™ or Select™ Master Keypad Module (see the Connections section of this manual for more details). A three-wire to RJ-45 adapter is available from Niles (see Accessories) for IR Sensors installed with two-conductor shielded cable rather than four-pair twisted cable.
Adding an IR Sensor enables the Niles R-4 Accessory hand-held IR remote, or a learning remote control programmed with Niles R-4 IR 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-Component Automation
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., the LS-1 Light Sensor and the APC-2 Current 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 Niles AC-3. The AC-3 is 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 Solo™ and Select™ Master 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-2P MicroFlashers™ connect 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. An IRC-1P Flooding 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-source system. 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-pair twisted 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-wide commands 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-component control is accomplished via the programming in the Master A4.6Ci. All Slave A4.6Ci’s in the system are left unprogrammed except 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.

Distributing Audio Signals
Audio signals for the shared source components are connected to both the A4.6Ci and the Home Theater receiver using the buffered cascade audio outputs (Figure 9).
Shared Source Component Control
The DATA output from the Home Theater IR repeater (the IRP-2+ in Figure 9) is connected to the IR Input of the Master A4.6Ci. The Home Theater IR Remote Control is now able to control the shared source components.
A 12V Sync signal is provided from the Home Theater to the Home Theater Sync Input to provide the A4.6Ci with the On/Off status of the Home Theater. This status enables the A4.6Ci to provide coordinated control of the source component's power On/Off.
Important Note: When issuing the source component’s actual IR commands from the Home Theater Remote Control, all IR commands are passed through to all source-component flasher outputs. Identical brand and model source components cannot be operated individually using these commands. (For more information on controlling identical brand and model source components, refer to the Operation Overview on page 28.)

Distributing Audio Signals
Audio signals for the shared source components are connected to both the A4.6Ci and the Home Theater receiver using the buffered cascade audio outputs (Figure 10).
Shared Source Component Control
The FLASHER output from the IntelliControl (Figure 10) is connected to the IR input of the A4.6Ci. The IntelliControl, programmed with Niles Remote IR commands, is now able to automate and control the shared source components. Niles IR commands are taught to the IntelliControl using the A4.6Ci and an attached flasher or the R-4 Remote itself (see Programming Overview for more details on page 45).
A 12V Sync signal is provided from the IntelliControl to the Home Theater Sync Input to provide the A4.6Ci with the On/Off status of the Home Theater. This status enables the A4.6Ci to provide coordinated control of the source component's power On/Off.
Important Note: When issuing the shared source components’ actual IR commands from the Home Theater Remote Control, all IR commands are passed through to all shared source component flasher outputs. Identical brand and model source components cannot be operated individually using these commands. (For more information on controlling identical brand and model shared source components, refer to the Operation Overview on page 28.)

In Figure 13, Zone #6 has been expanded into two rooms that can be On/Off individually and be set at different volume levels. Impedance magnification is incorporated in the Silencer to enable the safe connection of multiple pairs of speakers to a single zone amplifier. Connection of three rooms with Master Keypads and Silencers to a single zone of the A4.6Ci is accomplished with a single Niles Expander. Five rooms is accomplished using two Expanders (see the Expander manual for more details).

Figure 16
In Figure 16, a Niles IR Sensor is connected to a Niles IRP-6+ for control of local components and to a Niles A4.6Ci for control of distributed components. A Niles SPK-1 Automated Speaker Level A-B Switcher switches the front speakers in the master bedroom from the A4.6Ci distributed sound system to the local surround-sound receiver system when the local system is activated. (See the Installation section of this manual for details on the required connections for the IRP-6+ and the SPK-1.)
Important Note: Use of an identical brand and type component in both the local and the distributed system (i.e., a Sony CD player in both systems) is not supported by this configuration. Individual operation of identical components may not be possible (refer to Connections section).
Audio signals for the shared source components are connected to the Home Theater receiver using the cascade audio outputs.

Important Note: Use this list only as a starting point. All the components for every brand listed were not available at the time of testing. To avoid unforeseen incompatibilities, Niles recommends always testing components you have not yet used with a A4.6Ci prior to specifying them in your installation.
Testing for a Possible IR Command Conflict
When using a Niles IRC-1P FloodFlasher,™ there are rare instances when the same IR command will operate more than one source component. This prevents the proper operation of another IR controlled component when the two are installed in the same system because the press of a single remote button causes both components to respond. Rare as this situation is, when working with unfamiliar equipment or two products that you have never combined in the same system, it is advisable to first test how these components interact with each other.
To test for this type of conflict, take all the remotes in the system and issue every command you will be programming in the keypads. Expose all components to each command and make sure that only the appropriate component responds.
Solving the IR Command Conflict if Present
Remember that conflicts of this nature are rare. However, if you find yourself in this situation, contact the manufacturers to ask if they are aware of the problem and if they have a solution. Perhaps they now have a different remote, or a chip upgrade for the product.
If the manufacturers do not have a solution, the problem may be resolved by using a Niles IRC-2P MicroFlasher™ instead of IRC-1P FloodFlasher.™ In cases where neither solution works, advise the client of the situation and explain that you must substitute another component.

SOURCE-POWER SYNCHRONIZATION
WHAT IS SOURCE-POWER SYNCHRONIZATION?
The A4.6Ci has been designed to keep track of the ON/OFF condition of the three source components connected to the system. This allows you to automate source components that utilize the same IR command for ON and OFF.
For this feature to function as designed, you need synchronization (sync) between the A4.6Ci and source components that utilize the same IR command for ON and OFF. This assures the users of the system that the A4.6Ci will always issue power commands correctly when they press a Master Key or the Off Key.
Source Power Sync makes it possible for users to always have a source component turn ON when they need it on and to always have all the components turn OFF when they turn the system off.
Source Components that Require Power Synchronization
Source components that utilize the same IR command for ON and OFF need to be synchronized. The power button for these source components sends the same IR command to turn the source components ON if they are 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). Conversely, synchronization keeps the A4.6Ci from issuing a “power” command when the OFF Key is pressed, if the source components are already OFF.
The A4.6Ci has three Sync Inputs for each of the source components. It allows synchronization via voltage and video signals. (see Choosing a Synchronization Method on page 25 for more information on how to synchronize components).
Source Components that Do Not Require Synchronization
Two types of components do not require synchronization: Those with separate ON and OFF IR commands and those with “latching power.”
Source Components with Separate ON/OFF IR Commands
Synchronization is not required for source components that are included with and respond to separate ON and OFF IR commands. When power commands are programmed as separate ON and OFF, the A4.6Ci will issue ON commands only if sync is not present. Separate OFF commands for source components are always issued when the last zone turns OFF regardless of sync status.
Source Components with “Latching Power”
Some source components, Such as CD players and tape decks, usually are plugged into the switched AC outlet of the preamplifier/receiver with which they are installed. These components simply turn ON when the system’s receiver/preamplifier turns ON, meaning that they “latch” into an ON or OFF state and do not need an IR command to turn ON or OFF.
Because they turn ON as soon as there is power on their AC cord, once the preamplifier/receiver is turned on, these components will turn on as well. They do not need individual synchronization.
Since the A4.6Ci does not provide a switched AC outlet, the 12V control output connected to a voltage-triggered AC power strip (i.e., Niles AC-3) provides perfect control of latching source component. (See Configuration 1 in the Systems Configurations section of this manual for more information.)
24
SOURCE-POWER SYNCHRONIZATION
CHOOSING A SYNCHRONIZATION METHOD
Once you establish that all source components in the system have compatible IR commands, the next step is to choose the appropriate sync method for each component.
There are two ways to detect when a component is ON or OFF: Video or Voltage Sync.

Video Sync
Video sync is the easiest and most reliable method of synchronization. Most video sources have a video output active only when the device is ON. This type of video output provides an excellent method for component synchronization.
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. Picture quality will be unaffected due to the high impedance of the sync input.
If the source component has two video outputs, the need for an RCA Y-adapter is eliminated. Simply connect the first video output to its normal system destination, and the second video output will be dedicated for the sync input.
25
SOURCE-POWER SYNCHRONIZATION
Voltage Sync
Voltage sync is also a reliable method of synchronization if chosen and implemented correctly. The sync inputs can detect the control out voltage from a Niles signal-sensing product interfaced to the source component.
Obtaining Voltage Sync
Current Sensing
Current Sensing synchronizes a component by detecting the changes in the AC power draw that occurs with a component when it turns ON and OFF.

Figure 19
In Figure 19, a Niles APC-2 Current Sensing Switch senses the change in power consumption of a CD changer when it is turned ON. When it senses that change, it outputs a 12V DC signal. The synchronized CD changer’s AC power plug is connected to the current sensing outlet on the APC-2. The APC-2’s 12V DC output is connected 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).
When using a Niles APC-2, a minimum change of 30W is required for reliable current sensing. If the component does not have a 30W change in current draw when turning ON (i.e., DSS receivers and most VCRs and CD players), consider the last method, Light Sensing.
26
SOURCE-POWER SYNCHRONIZATION
Light Sensing
Using a light sensor (LS-1) to synchronize your components is usually your last choice, simply because the other choices are more reliable. 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 miniplug to RCA adapter is required for this connection (see Connections for more information).

In Figure 20, a Niles LS-1 Light Sensor senses changes in brightness of a DSS’s front-panel LED and outputs a 12V DC signal when the LED is brightest. A blocking cover prevents ambient light from falsely triggering the LS-1.
An unused optical digital output on the rear panel of a digital source component also can provide a light source for sync using the LS-1.
SOURCE AND HOME THEATER SYNC STATUS
Sync status (the presence or absence of a valid sync signal) of source components and the Home Theater associated with the Master A4.6Ci are displayed on the LEDs located in the hidden programming panel. These LEDs illuminate only while a valid sync signal is being received by the A4.6Ci during normal operation mode. Source 2, Source 3, and Source 4 LEDs represent Source 2, Source 3, and Source 4 respectively. The Tuner LED represents the Home Theater. These status LEDs are used during system troubleshooting. Manually turning ON/OFF synchronized source components and the integrated Home Theater will turn ON/OFF the respective component’s status LED if synchronized correctly.

Event 1
This event turns the appropriate Zone ON when a Master Key is pressed. Additionally, the 12V Control Output activates when the first zone in the system turns on during this event.
Note: Pressing and holding a Master Key turns on all zones assigned via DIP switches located on the front panel.
Event 2
The Zone-ON Sequence event is programmed with IR commands and/or delays. Each zone has its own programmable Zone On Sequence. However, unlike other Master Key events, the Zone-ON Sequence only occurs when that zone first turns on. It is typically used for light controllers and discrete component commands.
Note: When a zone issues a system-wide ALL ON command, the Zone-ON Sequence event occurs only for that zone.
Event 3
The source input assignment for the Master Key is programmed into the System Input event individually for each Master Key. These inputs are selected every time a Master Key is pressed or pressed and held.
Event 4
The Source Power event is programmable with IR commands individually for each Master Key. IR commands taught to the Master Keys assigned to inputs 1 and 2 are issued conditionally and based on the presence of a sync signal at the corresponding sync port.
Event 5
The System-ON Sequence event is programmed with IR commands and/or delays and only occurs when the first zone in the system turns on. 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. It occurs every time the Master Key is pressed and is typically used for source play or channel commands.
Note: A two-second delay is automatically executed prior to the Master Key Sequence when the first zone in the system is activated or when a component power command is issued during Event 4.

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. The quickly tapped Master Key illuminates GREEN after the zone turns ON.
System-Wide Operation
The second method, a press and hold of a Master Key/Source Button in any zone (holding the key/button for more than three seconds), turns all zones ON that are set to ALL ON/Page Enabled (this setting is made via front-panel programming DIP switches, set individually for each zone). All zones enabled for ALL ON/Page select the source associated with the Master Key/Source Button pressed and held, and that same Master Key LED illuminates GREEN.
Zones responding to system wide commands turn ON to a default volume. This volume can be individually adjusted for each zone (see the programming section of this manual for details.)
OFF KEY/OFF BUTTON
The OFF Key/Button included on the Solo™ and Select™ Master Keypad Module and the R-4 Remote provide one-touch system deactivation. When you finish listening in a zone, a single press of the OFF Key/Button deactivates the zone.
