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).

CAUTION:

Since the IRIS remote is fun for many adults, it is likely that small children will also find it so. After a system turn-on, the REMOTE knobs may not be set where you left them at last listening. If you

then TOUCH either remote knob, you may suddenly have a lot more level than you expected!

Your instinctive reaction of quickly reducing the remote VOL- UME setting will take this level down very quickly. However, in such situations, a better approach is to use a remote KEY to either (-20dB) MUTE the system, or select an unused or dead input-BEFORE TOUCHING either remote knob then restore the remote VOLUME control to normal level and operate as usual.

The preamplifier’s CYBER-OPTIC level-control system has essentially infinite resolution-as no digital steps are used. In the remote V/B transmission mode IRIS employs 8-bit or 256-step format to obtain resolution essentially indistinguishable from preamplifier panel operation. For VOLUME, the command step-size is approximately 0.25dB, increasing in the deep- cutoff region. For BALANCE, the command step-size is typically 0.1dB.

Engage either RECORD 1 or 2 on your preamplifier. You will find that most of your remote KEY functions are not being accepted at the preamplifier, but VOLUME BALANCE, MUTE AND NORMal are working as usual. This unique IRIS feature allows you to retain convenient remote control of those functions which come AFTER the RECORD OUTPUT jacks in the preamplifier signal path, but keeps you from accidentally input- ting any commands which would spoil your recording process.

An INTERRUPTED flashing of the preamplifier’s MUTE indica- tor tells you which functions it will not accept during this safety mode.

IRIS specifications

The Hafler IRIS is a noteworthy advancement in the realm of audio technology, particularly designed for audiophiles and sound engineers seeking high fidelity listening experiences. This speaker system epitomizes the confluence of innovative design and high-performance engineering, making it a favored choice among sound enthusiasts.

One of the standout features of the Hafler IRIS is its utilization of advanced crossover technology. The IRIS employs a meticulously designed passive crossover network that ensures a seamless transition between different frequency ranges. This technology allows for crisp highs, detailed mids, and powerful lows, creating a well-balanced sound profile that can accurately reproduce even the most complex audio tracks.

The speaker design incorporates a unique enclosure that minimizes distortion and enhances acoustic performance. This sturdy construction not only mitigates unwanted vibrations but also provides an optimal acoustic environment for sound reproduction. The IRIS is crafted with high-quality materials, including dense MDF (Medium Density Fiberboard), which further contributes to its robust build and resonance-free performance.

Another significant characteristic of the Hafler IRIS is its driver configuration. The system typically includes a high-performance woofer, midrange, and tweeter, each meticulously selected to ensure compatibility and performance consistency. The woofer is designed to deliver deep bass response, while the midrange driver excels in delivering vocals and instrumental clarity. The tweeter is engineered to reproduce high frequencies with precision, ensuring that every note resonates with clarity.

Hafler has also integrated innovative technologies to enhance user experience. With features like bi-wiring capability, audiophiles can connect their amplifiers directly to the woofer and tweeter separately, allowing for improved control over each driver’s performance. This flexibility enables users to tailor their listening experiences to meet personal preferences and requirements.

Furthermore, the Hafler IRIS is designed to fit seamlessly into a variety of audio setups, whether in professional studios or home listening environments. Its sleek aesthetic allows it to complement modern décor, making it an attractive addition to any space.

Overall, the Hafler IRIS delivers a compelling mix of design, technology, and sound quality, making it a preferred choice for those who seek a sophisticated listening experience. Its commitment to high performance and user-centric design principles ensures that it stands out in the competitive landscape of audio technology.
