INTRODUCTION
The Hafler IRIS system is a major step forward in the world
of audio technology. The IRIS CD completes an intensive
engineering effort to create a series of components which
offer superior performance combined with the unprece-
dented convenience of the IRIS remote control.
The basic operation and features of the IRIS CD Player are
described in simplified form in figures 1 and 2. Although
operation of the CD Player is possible by studying these
diagrams only, complete appreciation of its features and
operating modes can only be realized by thoroughly read-
ing this owner’s manual.
We have tried to present this information in an easy to
follow format. We urge you to take the time to read through
this manual as soon as possible.
INSTALLATION
SET-UP OF THE IRIS CD PLAYER
FREE STANDING
Always set the player horizontally on a flat, firm surface.
Allow a minimum space of a least
14" above the player so
as not to interfere with the cooling of the player.
STACKED
Locate the player preferably at the bottom. Never set the
player directly on top of a high-power amplifier, because
such an amplifier gives off a substantial amount of heat.
RACK MOUNTING
The IRIS CD Player is shipped with removable end caps
on its front panel. Optional rack mounting ears are avail-
able from the factory for mounting the unit in a standard
19” equipment rack.
1

WARNING- Never allow the player to stand for long
periods in direct sunlight or near any heat source.
CONNECTIONS
REMOTE CONTROL
The IRIS CD has two recessed male connectors on the
back panel. They are internally connected together to
allow the IRIS digital data-bus to “daisy-chain” to other
IRIS-compatible accessories.
Connect either end of the supplied ribbon-type umbilical
cable to either of the CD’s connectors. Note that both of
the cable’s connectors are keyed, and therefore fit only one
way. Be sure to insert the plugs fully. Connect the free
end of the cable to the connector on the rear of (either) the
IRIS Preamp or IRIS Tuner.
AUDIO
Output Right/Left: For the signal output to the preamplifier.
Connect a standard RCA-type patch cord from the right
and left outputs into the corresponding CD input jacks of
your IRIS preamplifier.
Digital: For digital output signal to an outboard Digital to
Analog (A/D) converter.
POWER
For AC line (mains) power. Make sure the line voltage on
the rear of the unit is appropriate for your location.

I
IRIS REMOTE CONTROL
TRANSMITTER
You should re-read the remote section of the IRIS
PREAMPLIFIER manual in conjunction with the following
additional information.
HANDSHAKE SYSTEM
The umbilical connection established allows a very con-
venient “HANDSHAKE” operation between IRIS SYSTEM
COMPONENTS. In simple terms, your IRIS CD Player
tells your IRIS Preamplifier that it is connected and
powered. This tells the Preamplifier, when CD is selected,
to automatically “transfer” the remote’s top eight (multi-
legend) keys to perform CD command functions.
All of the KEY functions of the CD Player panel which are
convenient from remote operation are available from the 8
remote KEYS:

CLEAR KEY
The CLR (CLeaR) key on the remote transmitter causes
the CD Player to stop and allows selection of another input
source to the IRIS Preamp within 3 seconds. If another
source is not selected within three seconds, the remote’s
key functions will remain in CD mode. If you wish to select
another source but keep the CD Player operational:
j Press the HOLD key (prior to the CLR key).
- This causes the CD Player to pause
- Press the CLR key
- Select another SOURCE
To return to the CD Player:
- Press CLR key
- Select CD
- Press HOLD key
- The CD Player will now continue playing
RECORD SECURITY
As explained in the “remote” section of the IRIS
Preamplifier Manual, if RECORD SECURITY is in effect
(either RECORD switch is IN on the IRIS Preamplifier), the
CD or Tuner will refuse all IRIS remote commands, includ-
ing CLR. (Volume and Balance are always active.) The
Preamplifier’s red MUTE legend will remind you of this by
its distinctive interrupted-flashing mode.
THE INDICATIONS OF THE DISPLAY
(Refer to Figure 2)
Each Compact Disc has, along with the music, a list of
contents detailing the numbers of the tracks, the playing
time of each track and the total playing time of the disc.
The player always scans this first and stores it in memory
to provide information via the display.

- Play is interrupted until selecting is finished.
- As soon as the playing time indication returns, the
selected track begins to play.
ifw (NEXT) is pressed while playing the last track, ERROR

PASSAGE DURING PLAY
Hold << (SEARCH) down to search backward to the begin-
ning.
Hold >> (SEARCH) down the search forward to the end.
As soon as the button is released play restarts at once.
The length of time for which the button is held down
determines the search speed:
- The first three seconds searching is relatively
slow.
- After approximately four seconds searching is
slightly faster.
- After approximately seven seconds searching
reaches highest speed.
At the first two speeds of searching, the sound of the disc
remains audible, although accelerated. When searching
by ear it is therefore advisable to release the button as soon
as the sound disappears.
If PAUSE has been pressed
before beginning searching, then no sound will be heard.
During searching, as soon as the beginning of the first track
has been reached, ERROR lights up. Play will resume
there as soon as the button is released. If the end of the
last track is reached, ERROR lights up. Play will resume
a few seconds before the end of the disc as soon as the
button is released.

sequence on the display.

ADDITIONAL INFORMATION
CARE OF THE DISCS
Although both sides of a disc are protected by a special
coating, it is
still advisable to treat the discs with care:
Never leave discs lying around: put them back in their
holders immediately after use. Never write on the printed
side! Do not attach any stickers on that side. Keep the
shiny surface of the disc clean. Use a soft lint-free cloth
and always wipe the disc in a straight line from center to

slight moisture.
Warning: Cleaning agents for conventional vinyl records
are not suitable for cleaning a Compact Disc, nor may
detergents or abrasive cleaning agents be used.
PLAYER MAINTENANCE
When cleaning the player and face-plate, we advise a soft
cotton cloth with a non-abrasive cleaner that is safe for
Lexan and painted surfaces.
DO NOT use paper towels or any course material to clean
the face-plate as these materials may scratch the insert.
The disc tray should be kept free of dust with a dry cloth.

SYMPTOMS AND THEIR LIKELY CAUSES
Insufficient familiarity with the combination of a new
product and new discs may lead to faults arising during
use. These are generally caused by a simple error in
operation or external factors.
It is perhaps useful to check the points listed below and
where possible remedy these before taking your player for
repair.
- Condensation has formed on the lens of the laser
due to a dramatic change in temperature. This will
disappear automatically after some time.
- There is a foreign object in the disc tray.
- The disc has not been inserted with the printed
side up or there is no disc in the tray.
- The disc is dirty, badly scratched or warped.
- The player has been connected to the PHONO
jacks of the preamplifier.
If the fault remains, try to clear it by switching the player off
and on. If this also fails to help, do not continue ex-
perimenting, but remove the plug from the socket and
consult your dealer.
Under no circumstances should you repair the player
yourself: this action will void the warranty!
