INTRODUCTION
Niles Audio has recognized the need for a simple to use, cost-effective 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 receiver that incorporates six separate zones of amplifier power, a built-in AM/FM tuner, and connections for three additional audio-source components.
The ZR-4630 MultiZone Receiver is the multi-zone solution for which you have been asking. 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 ZR-4630's source-component IR control is custom-programmable to provide intuitive operation for a wide range of source components.

The design approach of the ZR-4630 MultiZone Receiver 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 ZR-4630. The Solo™ Master Keypad Module, Numeric™ Accessory Keypad Module, and Niles IR Sensors connect to the receiver for complete system control.
Total system cost is now 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 made fast and easy via push buttons and LED visual prompts that lead you step-by-step through the programming process. Additionally, all system programming can be archived on your PC for back-up and for use with pre-designed systems with Niles ZR-4630 Archiving software.
One-Touch Operation with Source Component Power Synchronization
One touch of a Master Key or Source Button initiates the ZR-4630 MultiZone Receiver to perform a sequence of IR commands for complete automation of your distributed A/V system.
Sync Inputs provided by the ZR-4630 sense if 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 are 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 ZR-4630.
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 ZR-4630. Custom labeled Master Keys provide complete system activation and source selection, while a complete set of cursor keys provides basic source transport and menu control.
The Numeric™ Accessory Keypad Module - The Numeric™ Accessory Keypad Module can be included along with the Solo™ Master Keypad Module in any or all zones. This combination provides direct access to discs, tracks, stations, and channels when operating DSS receivers, CD/DVD changers, and the built-in AM/FM tuner.

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 ZR-4630 MultiZone Receiver 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.
Expandable for Larger MultiZone Systems
Up to three ZR-4630’s can be combined in a single system, providing 18 zones. Source components are connected to all receivers, splitting their audio signals utilizing RCA Y-adapters or Niles AVDA-3 Distribution Amplifiers.
Program Memory Protection
The ZR-4630 MultiZone Receiver utilizes non-volatile memory for storage of its programming. This safeguards against accidental loss of the programming for the entire life of the product.

Figure 4
This is the simplest of the ZR-4630 configurations (see Figure 4). It depicts one Niles ZR-4630 MultiZone Receiver installed to provide sound to six listening zones.
Each zone consists of one room with one pair of speakers. One Solo™ Master Keypad Module is included in each zone for user control. Numeric™ Accessory Keypad Modules and an IR Sensor are added to specific zones as an option.
Source Components
The ZR-4630 has RCA audio inputs for connecting three external source components. In addition to the builtin AM/FM Tuner, three source components can be selected 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 ZR-4630 MultiZone Receiver and its connected source components. Source component IR commands are programmed into the Niles ZR-4630 MultiZone Receiver. 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 ZR-4630 has a corresponding RJ-45 keypad connector that is used to connect one Solo™ Master Keypad Module. Each Solo™ Master Keypad Module can be mated with one optional Numeric™ Accessory Keypad Module using an included jumper cable (see Connections, Figure 33). The Solo™ Master Keypad Module connects to the ZR-4630 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™ Master Keypad Module (see the Installation 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 Remote to control the ZR-4630 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 ZR-4630 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 41 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 ZR-4630. When the Master Key/Source Button for the DSS is pressed, the ZR-4630 checks for a video signal at the Sync Input corresponding to the DSS. The ZR-4630 issues the power command to turn the DSS ON only when there is no video signal present and the DSS is OFF.
When the Off Key/Button is pressed in a zone, the ZR-4630 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 there is a video signal 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 Connections on page 44 fo 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 from the ZR-4630 when any one of the six zones is ON (including the Home Theater Zone sharing sources). The built-in AM/FM tuner is also turned ON when one of the six zones is ON.
Each Master Key on the Solo™ Master Keypad Module and its respective source component are programmable with a sequence of IR commands. 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 ZR-4630 MultiZone Receiver. Flashers send IR commands to the individual source components for control. An IRC-1P Flooding Flasher can be connected to the Flasher output labeled ALL to control more than one source component.
Speakers
Each zone has “home run” speaker cables from the location of the speakers for connection to the built-in zone amplifier. Connections are made to the ZR-4630’s speaker output terminals utilizing Niles’patented no-strip speaker connectors.
14
SYSTEM CONFIGURATIONS
CONFIGURATION 2 – ADDING ZONES USING MULTIPLE ZR-4630’S
More than one ZR-4630 can be used if the system requires more than six zones. A maximum of three ZR-4630’s, providing up to 18 zones, can be combined to create a larger multi-zone/multi-source system. One ZR-4630 is designated as the Master and the others as Slaves (see Installation Settings on page 58 for more details).

Figure 5
As shown in Figure 5, a four-pair twisted cable connecting the expansion ports of the two ZR-4630’s facilitates communication between them. This communication enables all zones provided by both ZR-4630’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 Two ZR-4630’s
The Niles ZR-4630 MultiZone Receivers (Figure 5) share the audio signal from the source components via RCA Y-adapters. Audio signals are connected to both ZR-4630’s.
Note: When sharing source components with a third ZR-4630 (for an 18-zone system) or with a Home Theater system, refer to Configuration 3.
Source-component control (Figure 6) is accomplished via the programming in the master ZR-4630. All Slave ZR-4630’s in the system must be left unprogrammed except for tuner preset stations. All Flasher and Sync Input connections for the shared source components are made to the Master ZR-4630. Keypad/Source Button commands and zone On/Off status are communicated to the Master ZR-4630 using the System Expansion In/Out connections, providing coordinated control of all source-components.

SYSTEM CONFIGURATIONS
CONFIGURATION 3 – DISTRIBUTING SOURCE-COMPONENT AUDIO SIGNALS
When sharing source components with three ZR-4630’s (see Figure 6) or two ZR-4630’s and a Home Theater system (see Figure 7), a Niles AVDA-3 Audio/Video Distribution Amplifier is required for each source.

Figure 8
Distributing Audio Signals
Audio signals for the shared source components are connected to both the ZR-4630 and the Home Theater receiver using RCA Y-adapters (Figure 8).
Important Note: If the Home Theater Receiver has shorting audio inputs, a Niles AVDA-3 Distribution Amplifier must be used in place of the RCA Y-adapters (refer to Figure 7).
Shared Source Component Control
The DATA output from the Home Theater IR repeater (Figure 8) is connected to the IR Input of the ZR-4630. 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 ZR-4630 with the On/Off status of the Home Theater. This status enables the ZR-4630 to provide coordinated control of the shared 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 32.)

Audio Signals
Audio signals for the shared source components are connected to both the ZR-4630 and the Home Theater receiver using RCA Y-adapters (Figure 9).
Important Note: If the Home Theater receiver has shorting audio inputs, a Niles AVDA-3 Distribution Amplifier must be used in place of the RCA Y-adapters (for more information see configuration 3).
Shared Source-Component Control
The Flasher output from the IntelliControl® (Figure 9) is connected to the IR Input of the ZR-4630. The IntelliControl, programmed with Niles R-4 Remote IR commands, now can automate and control the shared source-components. Niles R-4 IR commands are taught to the IntelliControl using the R-4 Remote itself (see Programming Overview for more details).
A 12V Sync signal is provided from the IntelliControl to the Home Theater Sync Input to provide the ZR-4630 with the ON/OFF status of the Home Theater. This status enables the ZR-4630 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 32.)
