Introduction
The Niles ZR-4 MultiZone Receiver Kit is a four-source, four-zone distributed audio system. The ZR-4 is packaged as a complete kit and includes a MultiZone Receiver with built-in AM/FM tuner, four weather-resistant keypads, a hand-held learning remote control, rack mount ears, and three infrared MicroFlashers® to control the connected audio sources. The system is easily expandable to eight zones with an additional ZR-4 MultiZone Receiver Kit.
This Niles ZR-4 MultiZone Receiver Kit is equipped with an AM/FM tuner designed to operate properly in your country. All of the configuration and operating procedures remain the same as outlined in the ZR-4 Installation Guide. However, note that the illustrations used in the Installation Guide depict north american AM and FM radio frequency numbers. This version’s radio frequency numbers may be different and will be appropriate for your market. If you have any questions please contact the Niles Technical Support Department at
Techsupport@nilesaudio.com or 305-238-4373.

Features and Benefits
Four-Source, Four-Zone MultiZone Receiver
Any of the ZR-4 MultiZone Receiver’s four audio sources can be routed to any of the four zone outputs to provide high-quality entertainment throughout the house
Built-In AM/FM Tuner
Provides out-of-the-box radio reception without additional components, connections, or programming
Weather-Resistant Keypads
The ZR-4 MultiZone Receiver Kit comes with four weather-resistant keypads to accommodate installations in moist areas such as bathrooms, spas, or even outdoors under an eave. Additional keypads are available as an option
Hand-Held Learning Remote Control
The included remote control comes pre-programmed to control most popular audio sources, and also “learns” the IR commands for other sources not included in the on-board library. Additional hand-held learning remote controls are available as an option
Three Analog Audio Inputs
Up to three external stereo audio sources, in addition to the built-in AM/FM tuner, can be connected, controlled and distributed to any of the four zones
Built-In Eight-Channel Digital Amplifier
Our high-quality digital amplifier delivers 40 watts per zone (20 watts per channel), generates minimal heat, and can comfortably drive two pairs of 8 ohm speakers per zone
RS-232 and Discrete IR Control For Each Zone
The ZR-4 MultiZone Receiver provides seamless integration with third-party remote control systems
Preamplifier Output and 12V Trigger
Makes it easy to add additional power with Niles Systems Integration Amplifiers® (zone 4 only)
Paging Input
Accommodates voice announcements from a telephone system and/or doorbell chimes (doorbell chimes require the Niles DBI-1 interface)
Independent Bass, Treble, and Variable Loudness Controls
Each zone can be custom-tuned to maximize sound performance and match room acoustics
Expandable To Eight Zones
System architecture allows expansion to eight zones via an additional ZR-4 MultiZone Receiver Kit
Supports Up To Two Keypads Per Zone
Ideal for use in large rooms (additional keypads sold separately; requires ZR-KE Keypad Expander)
Zone Linking
Permanently group up to four zones per chassis: turn-on, source selection, and turn-off work in unison, yet each zone retains independent volume, bass, treble, and variable loudness control
Party or Whole House Mode
Temporarily turns on the entire house (or a pre-set number of zones) to the same audio source for entertaining large groups
virtual Home Theater Zone
Enables source sharing with an independent home theater system via the global IR input and home theater sync

5) Expansion Connection – This RJ-45 connector allows data to be carried between a Master and Slave ZR-4 over CAT-5 cable to create an eight-zone system
6) Keypad Ports – Four zone-specific RJ-45 connector ports connect to each zone’s keypad with CAT-5 cable using the T568A wiring convention
7) Flasher Outputs – Four 3.5mm connectors. The three supplied Infrared MicroFlashers® connect to flasher outputs 2-4 and then attach to each source component’s respective IR window.

Place the ZR-4 MultiZone Receiver on a flat, level surface such as a table or shelf, with its weight equally distributed on each of its four feet. Placing the weight of the receiver on the rear or front panel for even an instant may result in damage to the receiver’s connectors and controls. Like any high-fidelity component, the ZR-4 MultiZone Receiver will last much longer if it is given adequate ventilation for proper cooling. When installing the ZR-4 MultiZone Receiver in a cabinet, be sure that the rear of the cabinet is open to receive fresh air in order to provide proper cooling. Place the ZR-4 MultiZone Receiver so it has air space above it (minimum 1.75”). If this is not possible, we suggest adding an optional Niles FM-1 or FM-1R System Cooling Module. If the receiver is located on a carpeted surface, place a board under the receiver’s feet. Do not block the ventilation holes on the top and bottom. When installed in a professional rack using the rack mounting ears, provide a minimum of 1 unit space above and below the ZR-4.

CAT-5 CABLE - T568A Termination
The ZR-4 MultiZone Receiver could have as many as five CAT-5 cables connected. Labels are recommended to describe where each cable originates (not to which terminal it connects). The CAT-5 must be terminated with RJ-45 connectors using the T568A wiring convention (Figure 2).

ZR-4 MultiZone Receiver Kit |

|
NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 305-238-4373 |
Source Components
The ZR-4 MultiZone Receiver has RCA audio inputs for connecting three external source components. In addition to the built-in AM/FM tuner, these three source components can be selected to play in any of the four zones. With this configuration, a user in one zone can listen to a source component while another user in a different zone listens to a different source component (e.g. the CD can be selected in Zone 1 while the AM/FM tuner is selected in Zone 2). Additionally, each of the four zones can be set to an individual volume level. If more than one zone chooses the same source component, control of that source component is shared between the zones.
Keypads
Keypads with built-in IR sensors plus a Hand-Held Remote Control enable the user to control the Niles ZR-4 MultiZone Receiver and its connected source components. The built-in AM/FM tuner is controlled directly from the Keypad. The input for the connected source components is also controlled by the Keypad, but all source component functions are controlled using the Hand-Held Remote Control. The Keypads connect to the ZR-4 MultiZone Receiver by a “home run” of CAT-5 cable terminated with RJ-45 connectors using the T568A wiring convention. (See Page 6).
MicroFlasher Outputs
The included Niles MicroFlashers® connect to the numbered flasher outputs on the rear panel of the Niles ZR-4 MultiZone Receiver. Niles MicroFlashers send IR commands to the individual source components for control. An optional Niles IRB-1 High-Output IR Flasher (FG01023) can be connected to the flasher port labeled High Output Flasher to control more than one source component at a time.
Global 12V Control Output
An optional Niles AC-3 Voltage-Triggered AC Power Strip (FG00242) can be connected to the 12V Control Output to automate source component turn-On and turn-Off, as well as an external power amplifier turn-On and turn-Off.
Loudspeakers
Each zone has “home run” speaker cables from the Niles ZR-4 MultiZone Receiver to the location of the speakers. Connections are made utilizing removable speaker terminals. These terminals accept speaker wire up to 16 AWG in size. The receiver’s high-quality digital amplification can accommodate one pair of 4 ohm speakers per zone or two pairs of 8 ohm speakers per zone without going into protection or shutting down.
AM/FM Antenna Connections
The included FM Dipole Antenna connects to the female 75 ohm coaxial connector and the AM Loop Antenna connects to the spring-loaded terminals labeled AM and GND. Antennas must be connected to both ZR-4s when using two ZR-4 MultiZone Receivers.
