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 be- come informed about them. We all have a tendency to read instruction manuals only if something doesnt 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 1. We strongly suggest that you take the time to read through this information as soon as poss ble. 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 frontpanel. 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 120 volts AC, 5O/60 Hz. Consult the factory for information on alternate connections. In most audio systems, it will be most convenient to plug the tuner into the preamplifiers 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. ANTENNA CONNECTIONS A simple T shaped dipole ribbon antenna has been sup- plied with your IRIS Tuner. Connect its leads to the rear 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. REMOTE CONTROL CONNECTIONS The following applies only to those audio systems using an IRIS Preamp with the remote option installed. The IRIS Tuner 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 r bbon-type umbilical cable to either of the tuners connectors. Note that both of the cables connectors are keyed, and therefore fit only one 2
