INTRODUCTION
The Hafler IRIS FM Tuner combines very high quality radio
and audio frequency processing, convenient automatic
features, and infrared remote-system control.
The tuner employs a quartz-crystal referenced digital
tuning system using a Phase-Locked-Loop (PLL) and a
microprocessor having a proprietary program.
The basic operation of the IRIS FM Tuner is described in
simplified form in Figure 1. Please note that this diagram
can give you just enough information to start operating
your IRIS Tuner.
Hafler products are designed to be easy to operate for new
or occasional users, but also to provide access to many
additional features and modes for those who wish to become informed about them.
We all have a tendency to read instruction manuals only if
something doesn’t work as expected. However, the IRIS
Tuner is part of a sophisticated remote control system,
designed to enhance listening pleasure and convenience.
Therefore, there are hidden features and modes you may
never know about or understand, if you do not take the time
to read through this manual.
We have tried to provide this additional information in a
convenient form, mostly in sections of the manual num-
bered to correspond to the circled numbers on Figure
We strongly suggest that you take the time to read through
this information as soon as possible.

INSTALLATION
The gloss black insert on the face-plate of your new Hafler
Equipment has been packaged with a removable protective
coating. Please peel off this protective coating following
installation.
When cleaning the face-plate, we advise a soft cotton cloth
with a non-abrasive cleaner that is safe for Iexan and
painted surfaces. DO NOT use paper towels or any coarse
material to clean the face-plate as these materials may
scratch the insert.
The IRIS Tuner is shipped with styled end caps on its front
panel. Rack-mounting ears are available from the factory
for standard
19”-wide
racks.
POWER CONNECTIONS
The IRIS Tuner is internally connectable for virtually all AC
line power systems. Unless otherwise labelled, all units are
wired for
information on alternate connections.
In most audio systems, it will be most convenient to plug
the tuner into the preamplifier’s switched outlet.

AUDIO CONNECTIONS
A standard RCA phono-type patch cord has been provided
for the audio signal connection. Simply connect this cord
from the rear-panel output jacks to the “tuner” or “radio”
input of the preamplifier.

panel terminal strip marked “300 ohm”.
For best results, the “arms” of the antenna should be fully
extended, and mounted against a wall or equipment
cabinet. For further information about placement of this
antenna, as well as guidance concerning alternate antenna
types, see the section “Additional Information”.
