Wellfloat in Iran

Amir Audio is the only Exclusive Distributor of Wellfloat in Iran.

G CLEF Acoustics was established in Osaka in 1978. For over 40 years the main business of G-Clef has been supporting and developing systems for professional mixing consoles and recording equipment such as SSL, Studer, etc. Our client list includes concert halls, TV broadcasting companies, local government, research institutes, universities and other major companies in Japan.

The original idea of pendulum in WELLFLOAT can be traced back to the childhood of the chief designer, Ryoji Nagata. Based on this 40 years’ experience of G CLEF, WELLFLOAT was developed to bring this innovation to the HiFi market.

Daniel Weiss is honored to receive the 2021 Technical Grammy Award

Daniel Weiss is one of the true pioneers of digital technology. In 1985, he founded Weiss Engineering Ltd. in Zurich, Switzerland. The company has designed and manufactured groundbreaking digital audio equipment for mastering studios, including the IBIS digital mixing console and the ultra-high-quality Gambit Series digital products.

The Lifetime Achievement Award celebrates performers who have made outstanding contributions of artistic significance to the field of recording, while the Trustees Award honors such contributions in areas other than performance. The Recording Academy’s National Board of Trustees determines the honorees of both awards. Technical GRAMMY Award recipients are voted on by the Academy’s Producers & Engineers Wing Advisory Council and Chapter Committees, and are ratified by the Academy’s Trustees. The award is presented to individuals and companies who have made contributions of outstanding technical significance to the recording industry.

TAD Laboratories in Iran

http://amiraudio.com/wp-content/uploads/2020/12/HADDS-1-scaled.jpg

Amir Audio is the only Exclusive Distributor of TAD Laboratories in Iran.

Technical Audio Devices (TAD) was originally the name given to a project launched by Tokyo-based Pioneer Electronic Corporation (currently Pioneer Corporation) in 1975 to develop high-end speakers for professional use.

Nearly 30 years after the first TAD-branded speakers were released, Technical Audio Devices Laboratories, Inc. (TADL) was spun off from Pioneer Corporation in 2007 as a company dedicated to developing and marketing a broader range of TAD-branded products, which include high-end amplifiers and disc players designed to bring the best out of TAD speakers. TADL’s mission is to inherit and advance the engineering prowess and assets accumulated by Pioneer in the high-end audio field over the years.

TADL Philosophy

  1. We offer products that deliver a truly immersive, soul-stirring music-listening experience and that make their owners proud.
  2. We hand-assemble every one of our products using the finest technologies and with uncompromising attention to detail, no matter how technology evolves and no matter how people enjoy music changes over time.
  3. We continue to innovate by incorporating new materials and technologies into our product design while adhering to the basic engineering policy and industrial design concept we have refined over the years.
  4. We design our products that withstand the test of time and employ materials and technologies available only in Japan to enhance their artistic appeal.

Computer Audio

Audio Industry is Affected by Computer Audio . Getting good Sound from Computer Audio is very Complex Challenge for Audio Designers Professionals Like Gordon Rankin (Designer of Wavelength Audio) who Have Tried to Improve Sound of Computer Audio.
In Amir Audio We Had good Result from Roon Ready Weiss DAC 501/502.
Roon Software (in Roon Ready Mode) use Ethernet Connection between Computer (or Music Servers Like Weiss MAN301) and DAC.
We never had good result from Ripped files and we only use Tidal streaming Services.
Tidal on Roon lets you play all your favorite music in High Fidelity sound quality.

Ground Loop

In an electrical system, a ground loop or earth loop occurs when two points of a circuit are intended to have the same ground reference potential but instead have a different potential between them.This can be caused, for example, in a signal circuit referenced to ground, if enough current is flowing in the ground to cause two points to be at different potentials.

Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. Wiring practices that protect against ground loops include ensuring that all vulnerable signal circuits are referenced to one point as ground. The use of differential connections can provide rejections of ground-induced interference. Removal of safety ground connections to equipment in an effort to eliminate ground loops also eliminates the protection the safety ground connection is intended to provide.

A ground loop is caused by the interconnection of electrical equipment that results in there being multiple paths to ground, so a closed conductive loop is formed. A common example is two pieces of electrical equipment, A and B, each connected to a utility outlet by a 3 conductor cable and plug, containing a protective ground conductor, in accordance with normal safety regulations and practice. This only becomes a problem when one or more signal cables are then connected between A and B, to pass data or audio signals from one to the other. The shield of the data cable is typically connected to the grounded equipment chassis of both A and B, forming a closed loop with the ground conductors of the power cords, which are connected through the building utility ground wire. This is the ground loop.

In the vicinity of electric power wiring there will always be stray magnetic fields oscillating at the utility frequency, 50 or 60 hertz. These ambient magnetic fields passing through the ground loop will induce a current in the loop by electromagnetic induction. In effect, the ground loop acts as a single-turn secondary winding of a transformer, the primary being the summation of all current carrying conductors nearby. The amount of current induced will depend on the magnitude of nearby utility currents and their proximity. The presence of high power equipment such as industrial motors or transformers can increase the interference. Since the wire ground loop usually has very low resistance, often below one ohm, even weak magnetic fields can induce significant currents.

Since the ground conductor of the signal cable linking the two pieces of equipment A and B is part of the signal path of the cable, the alternating ground current flowing through the cable can introduce electrical interference in the signal. The induced alternating current flowing through the resistance of the cable ground conductor will cause a small AC voltage drop across the cable ground. This is added to the signal applied to the input of the next stage. In audio equipment such as sound systems, the 50 or 60 Hz interference may be heard as a hum in the speakers. In a video system it may cause onscreen “snow” noise, or syncing problems. In computer cables it can cause slowdowns or failures of data transfer.

High Quality AC Power

Optimum performance of the highly sophisticated electronics that comprise today’s high-end audio system is hugely dependent upon a clean and stable supply of electrical current. Conversely, the modern day world, with its myriad of electrical devices, does much to degrade the electricity that we receive.

The AC Power Quality has a significant effect on Sound Quality but Most AC Filters and AC Regenerators in the Market Kill dynamics.

We Recommend using Class D AC Regenerators like Pure Power or Victron Energy Inverters/Chargers.

Determining Proper AC Polarity by Listening to Music

Every component in an audio system is sensitive to AC polarity. Ensuring that your electronics are connected to the AC line with the correct polarity is essential if you want to realize the full potential of your system.

Some believe Correct AC Polarity is related to lower Chassis Voltage when the ground lifted but There is no need to measure the Chassis Voltage (to Ground Potential) because in some rare instances, the higher reading Voltage will produce better sound from the component. the best way is listening and detecting the Correct AC Polarity.

Plug the component into the wall socket and turn on the power switch. Listen to Music, then Unplug the component from the wall socket, Reverse the position of the plug in the wall socket and repeat Listening.
The correct A/C alignment will be the one that gave the best sound.
