Automatic Transfer Control | Hafler IRIS specification

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.

The transmission of analog control positions to the preamplifier works much like the process used in digital recording and playback. Duringeachof these 1/8-second transmission frames,

the transmitter takes an Analog-to-Digital (A/D) conversion of the BALANCE knob position, transmits it twice, in different forms, then takes an A/D conversion of the VOLUME knob position, and similarly transmits it, then flashes the RED (Completed-Frame) LED at the top of the remote transmitter.

During the same 1/8 second, the receiver carefully checks the incoming BALANCE code-format, loads the BALANCE data into a temporary storage register, then carefully checks the VOLUME code-format, and if BOTH pass ALL checks, finally sends both data sets to Digital-to-Analog (D/A) conversion overriding the analog DC Voltages of the preamplifier’s knobs to the CYBER-OPTIC attenuator system.

To give you completely natural and safe analog command of VOLUME and BALANCE at both preamplifier panel and re- mote, IRIS automatically transfers control authority immedi- ately to whichever knob-set you use. Control stays there until you use the other set of knobs.

At preamplifier power-up, V/B control always reverse to the preamplifier’s knobs, because the unpowered preamplifierdoes not “remember” previously entered remote data. The green panel V/B LED lights, indicating this PANEL V/B mode.

This indicator is also used in a bright FLASHING mode to indicate each new arrival of valid V/B data from the remote. The preamplifier automatically transfers to the V/B settings of the remote knobs on the FIRST flash of this indicator. After the transmission, this indicator will then remain UNLIGHTED, indicating that V/B control has moved from the preamplifier PANEL knob settings to those of the REMOTE knobs.

V/B control will return to the preamplifier’s knobs if either is slightly TURNED-indicated by the V/B LED returning to its statically LIGHTED state.

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.
