Niles Audio IRZ-6+ Owner's Manual

The IRZ6+ is a unique multi-zone IR
Main System Unit. In many ways it
is as if six IR Repeater Systems are
combined. The IRZ6+ controls
which of your audio/video compo­nents will receive IR commands
from a remote sensor/keypad. Via
it’s configuration switches you may
control a particular component
from only one sensor/keypad or
you may choose to control a com­ponent from any combination of
remote sensor/keypads throughout
the system.

This enables you to use multiple
identical preamps/receivers to cre­ate a multiple-zone audio system
using identical IR commands with­out any conflicts between users.

Each preamp/receiver with a
switched AC outlet can be equiped
with a 12v DC wall adapter. The
wall adapter plugs into the appropi­ate status feedback signal to the
sensor/keypad for that zone only.
Additionally, IR commands to a
common source (e.g. a CD chang­er) can be routed from any or all of
the zones.

The IRZ-6+ is on e of several ele­ments that make up an infrared
extender system:

1. IR Sensors receive IR com­mands from hand-held remote
controls and relay the commands
to the IR Main System Unit via a 2­conductor shielded cable.
Generally, sensors are placed so
that you can easily and naturally
point your remote control directly
at them. Niles offers an array of eas­ily concealable sensors: wall-mount,
ceiling-mount, surface-mount and
table-top. IR sensors are the “eyes”
of the system.

2. Keypads memorize IR commands
from hand-held remote controls and
reissue the commands to the IR
Main System Unit via a 2-conductor
shielded cable. Generally, keypads
are placed so that they are conve­nient to doorways, telephones etc.
Keypads give you a remote control
you cannot misplace.

3. The IR Main System Unit pro-
vides a connection hub for the IR
sensors and the IR flashers and is
generally located near the A/V com­ponents. The IR Main System Unit’s
level controls and LED indicators
enable you to configure, calibrate
and troubleshoot an IR extender
system. The Main System Unit is the
“heart” of an IR extender system.

4. IR Expansion Units enable you to
expand the number of sensor/key­pads a Main System Unit will support.

5. Infrared Flashers transmit the
infrared signals from the IR Main
System Unit to your A/V compo­nents. Niles manufactures flooding
flashers (model IRC-1) and miniature
“pin-point” flashers (model IRC-2).
The miniature “pin-point flasher is
the appropriate flasher to use with
the IRZ6+ since it incorporates a
blocking cover which prevents IR
commands from reaching other
components.

Introduction

The IRZ6+ offers a number of
improvements over other IR Extender
Main System Units:

• Universal system—compatible with
virtually all brands of A/V equip­ment and remote controls (the
only exceptions are those brands
using carrier frequencies higher
than 64kHz).

• Built-in “Status” generator for each
of the six zones broadcasts the
amplifier “on/off” power status over
existing IR wiring to provide power
status display when used with other
Niles products like the IntelliPad that
feature status display LED’s.

• Allows the creation of as many as 6
independent zones, and among
those zones supports as many as

16 local and/or central sources (in
four configurations). A simple addi­tion (the XRP6+ IR Expansion Unit)
provides IR control for zones con­taining multiple rooms.

• Accommodates 6 IR sensors and
keypads. Provides for 10 IR flasher
outputs. Six flasher outputs are
DEDICATED; the remaining 4 are
ASSIGNABLE via DIP switches to
any or all of the 6 sensors. A screw­pot adjustment labeled ADJUST
permits varying the level of each
flasher output. This prevents com­ponents from being overloaded by
too much IR.

• IR DATA OUT connector with corre­sponding assignable DIP switches is
provided for use with Niles prod-

ucts such as the RSL-6 and RVL-6.

• A supplied 110v-12v DC adapter
powers the IRZ6+.

• Red "Power" L.E.D. enables you to
test for proper power supply opera­tion and shorts between + (posi­tive) and GND (ground) on your
sensor connections.

• Green "IR" Test L.E.D. enables you
to test for proper operation, interfer­ence, and for shorts between + and
DATA on your sensor connections.

•Screw connectors simplify installation.

• Printed circuit board design assures

high reliability.

• Two year parts and labor warranty.

• Proudly made in the USA.

Features and Benefits

In an IRZ6+ system, each zone uses
an IR-controlled AM/FM receiver
which operates independently.
(Using multiple AM/FM receivers
rather than a single central tuner
allows each zone to select its own
radio station.) Typically, you place the
receivers in a central location. The
IRZ6+ can be tucked away out of
sight near the receivers, but should
remain accessible for upgrading or
changing its configuration.

Install IR sensors/keypads in an
appropriate location in each zone.
Use an individual home-run of 2­conductor shielded cable for each IR

sensor/keypad — West Penn D-291
or equivalent (IR cable of this type
may be purchased from Niles).

An IR command from any
sensor/keypad is routed to a corre­sponding DEDICATED flasher output
which feeds that zone’s receiver. The
IRZ6+ prevents IR conflicts by rout­ing the IR commands from each
zone directly to the proper receiver.
However, if identical makes and
models of receivers are used (a likely
situation), the installer must specify
the Niles IRC-2 micro flashers. The
IRC-2’s attach directly over each
receiver’s IR sensor window and fea-

ture a blocking “cover” which pre­vents IR from “leaking out” to a
neighboring receiver.

For control of source components,
the IRZ6+ provides 4 configurable
flasher outputs. For example, in a
simple six zone system with a CD
player, an IRC-2 MicroFlasher is
attached to the CD player IR sensor
window and a blocking cover is
installed. The flasher is connected to
one of the configurable flasher out­puts. The configuration switches for
that output are all set to the ON
position. See figure

Flasher Configuration
switches: Flasher out­puts A-D are individually
assignable to accept IR
signals from any or all of
the 6 zones.

Powered by a 12v DC
Adapter (Niles Part#
XF0019) supplied with
unit. Do not substitute
other adapters.

Individual level controls
to adjust the output
power of each flasher. for
maximum output, turn
controls fully clockwise
(Refer to the selection tit­tled “Operation” for more
information.

Individual status input
jacks for each zone
enables the IRZ6+ to
broadcast status feed­back. Connect a 12v DC
power supply of at least
200 ma output to the
switched AC outlet on
the rear of each zone
preamp/receiver.

LED indicator lights
when receiving a com­mand from any IR sen­sor. If this LED fails to
light, or stays lit, a prob­lem is indicated - per­haps electrical interfer­ence, or excessive sun­light hitting a sensor.
Refer to the Niles “IR
Troubleshooting Guide”
for more information.

Individual outputs for 10 IR Flashers - 6 dedicated and 4 assignable
via dip switches to any or all of the 6 sensors. High speed mosfet
output circuitry ensures distortion-free IR transmission. To connect
more than one flasher to a single flasher output, refer to figure 4.

Individual inputs for 6 IR sensors - one for
each zone. All remote sensors must be home­run using 2- conductor shielded cable. Do not
wire the sensors in a “daisy-chain” or connect
more than one sensor to a single input. Use
the XRP6+ IR Expansion Unit if connecting
multiply sensors within a zone.
