Hafler Iris Preamplifier.
It is a good habit to turn down BOTH remote and main panel volume controls upon system shut-down. This will avoid possible sudden and unexpected changes in volume when system is re-activated. TABLE OF CONTENTS Introduction ............................
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 in- stallation. When cleaning the face-plate, we advise a soft cotton cloth with a non-abrasive cleaner that is safe for lexan and painted surfaces.
Power IRIS is internally connectable for virtually all AC line-power Connections systems. Units not marked otherwise, on the rear panel, are connected for 120 Vofts, 50-60 Hz. Two SWITCHED outlets and one UNSWITCHED outlet (U.S. 120 Volt standards) are provided on the rear panel.
High Level IRIS has seven pairs of main HIGH LEVEL inputs, selected by Inputs the seven (oval) KEYS to the right of the phono KEY. All of these (Oval Key inputs proceed at unity gain to the attenuator/line-amplifier selected) system, which has a maximum gain of 20dB.
OPERATION Turn-On/Off logic Muting System Volume/ Balance System CAUTION: The EPL switch and the tape MONITOR switches, explained later, are often the cause of an apparently “dead” system, when they have accidentally been left engaged. Always check them first if a system is found “dead” on turn-on.
The EPL and Tape Loop Systems The actual audio attenuation elements are passive optically- controlled resistors, arranged in a special CYBER-OPTIC control circuit (patent applications in progress) which allows a combination of very low distortion and stereo tracking accuracy (typically 0.

Recording Any recording requires that you activate either the RECORD 1 System jacks, the RECORD 2 jacks (or both) using the RECORD 1 or RECORD 2 switches on the panel. As seen in the signal flow diagram, this makes any input selectable by the KEYS available to these outputs.
Tape The tape MONITOR switches at first appear to allow only a Monitoring redundant selection of what you hear from your deck(s) when Switches you use the TAPE KEY(s).
USING THE IRIS REMOTE SYSTEM Infrared Remote Integrated System INTRODUCTION Key Command Transmissions volume/ Balance (V/B) Command Transmissions The IRIS preamplifier achieves its infrared (IR) remot.
Automatic Transfer of V/B Control Note: The touching of BOTH knobs simultaneously will some- times inhibit operation of the touch-sensing system. The knob- touch system overrides any KEY-type command-so that KEY commands will not transmit, if you are accidentally touching either knob.
Remote V/B Resolution Record Security and Umbilical systems Note: Which V/B knob-set is in command is unaffected by ANY KEYS-remote or preamplifier. It depends ONLY in where the LAST V/B command came from (including the effects of pream- plifier power-up discussed earlier).
sx (Serial eXternal KEY The rear of the IRIS receiver card has a recessed, keyed male connector which carries needed digital signals for allowing the IRIS system to be connected to coming Hafler IRIS-compatible accessories, in a manner similar to which dispersed computer terminals can share the same data lines without confusion.
and pull the cover off. 2) The battery polarities are clearly marked in the plastic holder, visible when the batteries are removed. 1) Remove the 4 screws on the bottom cover of the transmitter, Carefully observing these polarity markings, replace all 4 batteries.
Even if you are experimenting, you must replace the cover before re-plugging in the unit to AC-not only for safety reasons, but to shield hum and interference which can totally invalidate any attempts at sonic evaluation.
