Inputs and Outputs
Overview: The Niles ZR-4 MultiZone Receiver Kit includes a multi-zone
receiver, four IR weather-resistant keypads, a hand-held learning IR wireless
remote control, three infrared microflashers and a set of rack-mount ears for
installing the ZR-4 into an equipment rack. The ZR-4 MultiZone Receiver Kit
allows distribution and control of up to four audio sources in up to four
listening zones. The ZR-4 is designed to intelligently manage source sharing
with your independent home theater system. You can expand this 4-zone system to
eight zones by linking a second ZR-4 MultiZone Receiver Kit via the unit's
MultiZone Receiver: The ZR-4 Multi-Zone Receiver features an advanced,
low-heat, 4-ohm stable digital power amplifier design which delivers eight
channels of robust power (40 watts per zone/20 watts per channel) with the
ability to comfortably drive two pairs of 8 ohm speakers or one pair of 4-ohm
speakers per zone. The ZR-4 multi-zone receiver has a digital AM/FM tuner built
in, so it plays music right out of the box without the need for additional
equipment. The ZR-4's tuner can store 20 AM/FM preset stations of any
combination. The ZR-4 receiver features a bright, backlit,16-character LCD
display for configuring the ZR-4 and also displays the current AM/FM preset
station, band and station tuning information. The unit also features four
front-panel Zone LEDs which illuminate whenever a zone is on and active. In
addition, the ZR-4 features front panel controls to operated the AM/FM tuner,
set favorite preset stations into memory and perform system configurations. The
unit's man power switch glows white to indicate the unit in standby mode and
ready to operate.
IR Weather-Resistant Keypads: The four supplied IR keypads provides
control for the ZR-4's built-in tuner and up to three additional sources. The IR
keypads will control source selection and local zone volume, muting and turn
off. You can also turn the entire system on or off with a single press of a
button from one of the keypads. The four IR weather-resistant keypads can be
installed most anywhere you want them, even in areas that get wet like
bathrooms, spas or out on the patio by the pool. Each keypad has a built-in IR
sensor that resists interference from flat-panel plasma or LCD TVs. The IR
sensor is defeatable for areas with direct sunlight. Each IR keypad includes
assorted laser-etched buttons for custom labeling of the keypads. Each keypad
can be installed ins a standard version single gang electrical box and
comes supplied with a white decorative snap-on wall plate. Each keypad features an RJ-45
connector and requires CAT-5 cable for connection. Each keypad also features a
12V trigger connection. The ZR-4 supports additional keypads in each zone
(additional keypads sold separately; requires ZR-KE Keypad Expander).
Note: Only the front panel of the keypad is weather resistant.
Learning Remote Control: The supplied IR wireless remote control
provides advanced control for the system's audio sources as well as the local TV
and a second local source such as a cable or satellite receiver. The remote
control comes preloaded with the commands for the ZR-4 and many popular brands
of equipment. Unique commands can be learned by the remote from various home
audio/video components. The remote also has the ability to create IR sequences
(macros). Additional hand-held learning remotes are available through the
Infrared MicroFlashers: 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. Each MicroFlasher features an attached 10' cord
terminated by a male 3.5mm minijack connector. In addition, each MicroFlasher
features a adhesive backing to secure it into place. 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.
Independent Audio Controls: Independent bass, treble, and variable
loudness controls enable you to custom tune each zone of the ZR-4 for the best
sound quality and match room acoustics from zone to zone.
Zone Linking: You can program up to four zones so that turn-on, source
selection, and turn-off work in unison. Each zone retains independent volume,
bass, treble and variable loudness control, which is a great feature for a
restaurant/ bar or for adjacent rooms such as a master bedroom and master bath.
Party Mode: With a single press and hold from a keypad or remote
control, you can turn on your entire house (or a preset number of zones) to
listen to the same source, which is ideal for entertaining or setting the mood.
Virtual Home Theater Zone: The ZR-4's virtual home theater zone
function enables source sharing with an independent home theater system using
the ZR-4's global IR input and home theater sync port.
Default Turn-On Volume: The turn-on volume level for the system is
adjustable. Since the turn-on volume level will be the same for all zones, Niles
suggests setting a comfortable listening level in the room that will be used
most frequently, or in the smallest room.
Rack Mountable: The receiver's rugged, 1U aluminum front panel
and included mounting ears and hardware provide for secure rack mounting while
taking up minimal space.
Inputs and Outputs
Expansion Port: This RJ-45 port allows you to expand the system to
eight zones by linking a second ZR-4 MultiZone Receiver Kit using CAT-5 cable.
Keypad Zones: The ZR-4 multi-zone receiver's four RJ-45 keypad
connections use T-568A CAT-5 termination. Connect each zone's master keypad via
a CAT-5 cable.
Flasher Outputs: Three 3.5mm ports used to connect the included IR
MicroFlashers and control up to three source components.
HP Flasher Outputs: 3.5mm port used to connect an optional Niles IRB-1
High Output IR Flasher (controls a stack of components with just one flasher)
HT Sync: This 3.5mm port enables sharing of components with an
independent home theater. When the home theater receiver is on, the ZR-4 will
stay active (even if all zones are off) and execute the appropriate 12V and IR
12V Trigger: When any zone is activated, the ZR-4's Global 12V Control
Output will send out a constant 12V DC trigger signal. This can be used to
automatically switch on an amplifier equipped with a 12V trigger turn-on, such
as a Niles System Integration Amplifier. Alternatively, the 12V trigger from the
keypad can be used to turn-on the amplifier only when zone 4 is active.
AM/FM Connectors: The multi-zone receiver features a 75 ohm FM antenna
connection and a 300 ohm AM antenna connection (this kit
includes both AM and FM antennas).
RS-232 Port: The ZR-4 MultiZone Receiver can be controlled by
secondary control systems via RS-232 devices and/or discrete infrared commands
using the system's 3.5mm RS-232 port.
IR In Global: This 3.5mm port allows you to control the ZR-4 and its
connected sources using a secondary control system.
Audio Inputs: Three pair of gold-plated RCA jacks are used to connect
up to the three stereo audio sources to the ZR-4 multi-zone receiver.
Voice Paging and Doorbell Chimes: The ZR-4 is equipped with a standard
RCA connector for Voice Paging and Doorbell Chimes. The ZR-4's paging input
enables you to connect a telephone system's paging output and/or an optional
Niles DBI-1 Doorbell Interface so that it automatically pauses the music and
plays through the system.
Zone 1/2/3/4: The ZR-4 is equipped with four stereo speaker
connections (one for each zone) that feature removable connectors that
accommodate 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.
Preamp Output: The ZR-4's pair of preamplifier outputs make it easy to
add additional power to the system. Assigned to Zone 4, the preamp outputs can
be switched between fixed or variable levels.
IEC Power Receptacle: The ZR-4 features a removable 6.5' power cord
for added flexibility when working in tight spaces.
