Below is the press release regarding Octave Audio tube electronics from Germany which are now being distributed by Dynaudio North America in the United States and Canada. Octave has been producing high-end tube electronics for over 20 years, and its integrated amplifier, power amplifier, and preamplifier models have earned a reputation for outstanding sound quality and incredible longevity – with a level of stability, reliability, and convenience of operation on par with that of the finest solid state designs.
Tubes are credited for the exceptional Octave sound quality, while semiconductor circuits help realize the tubes’ full audiophile potential while enabling Octave’s exceptional product durability. The company’s sophisticated control and protection circuitry, soft-start technology, accurate stabilization, and intelligent protection circuits ensure outstanding reliability, while biasing is made simple and easy – yet extremely accurate. Every Octave amplifier is hand-built from the highest grade components, including transformers produced entirely in-house at the company headquarters in Germany.
Dynaudio will be exhibiting at the AK Fest 2009 (May 2-3, in Livonia, MI in suites 552 & 553), where the company will introduce Octave to the market.
Dynaudio North America is proud to announce that it has been appointed as the distributor for Octave Audio for the USA and Canada. Octave Audio, based in Karslbad-Ittersbach Germany, has been producing high-end tube electronics for over 20 years. Today Octave offers a wide range of tube-based amplification products ranging from the attractively priced V40SE integrated amplifier up to its state-of-the-art Jubilee preamp and mono block amplifiers. Engineered and built in Germany, Octave models incorporate unique monitoring and protection systems and an innovative combination of sophisticated tube and elegant semiconductor circuitry.
Octave integrated and power amplifiers feature an extremely accurate bias control calibration system that anyone can use to precisely bias the tubes. In contrast to simple Class A power amplifiers, Octave amplifiers operate in Class A/B, which demands precise setup and control of the bias current. The sophisticated built-in bias calibration system simplifies this adjustment, which is crucial to sound quality. As the bias adjusters on Octave’s amplifiers are outside the case and complimented by front panel display indicators, anyone, regardless of their technical knowledge, can easily adjust the bias of the individual tubes to an extremely high level of precision – within 0.3% accuracy – without any special tools or measuring equipment necessary.
Octave (integrated and power) amplifiers also feature power management with soft-start control, which extends component and tube life by smoothly ramping up the tube heaters and operating voltage from switch-on. Thus, the power supply components never have to deal with the usual huge inrush of switch-on current. This extends component life considerably, ensuring that every Octave amplifier performs at peak performance for a very long time. They also feature an advanced electronic protection system that continually monitors the output level of the tubes. Should the output be short-circuited or overloaded, the protection system acts immediately to electronically isolate the power supply and protect the components. Combined, the power management and protection systems provide optimum all-around protection, which will even safeguard against abuse. The systems protect the amplifiers from damage through incorrect usage or tube faults, making Octave amongst the very few tube amplifiers that are as easy to operate as top quality transistor designs.
In addition to offering protection against faults, the aforementioned systems also extend tube life expectancy to 3-5 years for the power tubes and 5 -8 years for the driver tubes. Octave integrated and power amplifiers have also been engineered to offer excellent load stability, optimizing their output transformers for 4 ohm loads, thus making the amplifiers perfectly at home driving any loudspeaker, including “real” 8 ohm models.
Octave preamplifiers feature electronic stabilization of the power supply, which serves to ensure a high stability of the sound as well as the bias setting during mains variations, while also yielding improved bass performance and a greater overall effortlessness of the reproduced sound.
