Octave Audio

The Octave Jubilee preamp optimally combines the properties of lamps and transistors. In the input stages, where it is important to obtain maximum gain with the least noise, double ECC83 triodes operate, and powerful transistors are installed behind them, allowing for low output resistance and good load characteristics.

The Octave Audio Jubilee 300B circuit is based on electronic power supplies for each 300V lamp, which guarantees the operation of three "tubes" in parallel mode. The voltage and heat dissipation are adjusted automatically, which significantly increases the lamp life and sound quality.

The Octave Jubilee Mono Ultimate reaches 225 watts of dynamic output power – the capabilities of large-scale power transformers and proprietary circuitry extend far beyond the traditional concepts of lamp technology. The device body is assembled from 8 mm aluminum, 2 mm steel and 50 mm X-MDF plates.

The special version of the Octave HP 700 SE tube preamp is based on the classic 1986 Octave HP 500 circuit design, and the modular design makes the device flexible, allowing it to adapt its functionality to the needs of the owner.

The Octave HP 300 SE is an improved version of the HP 300 MKII. The new device is more versatile in terms of switching, has some improvements in the output stage and has an external power supply, which helps isolate its sensitive circuits from noise and interference from the power grid. It is possible to stepwise change the gain (three options are available), which makes it possible to precisely match the Octave HP 300 SE with the terminal amplifier and speaker.

The Octave Phono Module Tube Preamp (IN 2 + IN 6 + OUT 2) is a version of the basic model with two MC phono corrector input modules and one output module with fixed and adjustable RCA connectors. In fact, this device has on board everything you need to work with vinyl turntables equipped with MC cartridges.

The Octave Phono EQ.2 is able to meet the needs of most fans of high-quality analog sound, dissatisfied with budget phono correctors, which are integrated into amplifiers or preamps and in most cases are manufactured according to the residual principle.

The flagship Octave V 80 SE model crowns the Octave series of tube integrals like a crown. The amplifier uses proprietary ODT technology, the essence of which is the thoughtful use of OOS (negative feedback), which ensures stability in operation and makes it possible to increase instant power output. The flagship has an impressive 120 watts per channel (4 ohms) by the standards of tube devices and is able to tame virtually any speaker system.

The model outputs 110 watts per channel at 4 ohms, which is a great achievement for tube amplifiers. The company notes that the new generation of ODT amplifiers is able to impress with its extreme linearity, stability and negligible distortion levels.

The model implements the proprietary Dynamic Bass Control (DBC) dynamic displacement control technology created by Andreas Hofmann. Thanks to this technology, the Octave Audio V 70 Class A amplifier can deliver up to 70 watts at its peak — and this is in pure Class A.

The Octave V 70 SE integrated tube stereo amplifier is made according to a push-pull pentode circuit, and develops a maximum power of 2 x 70 watts when operating on 4-ohm acoustics. Like all Octave equipment, this device is completely manufactured at the company's own factory using both time-tested and state-of-the-art technologies, as well as selected components.

The Octave V 40 SE integrated tube amplifier develops an output power of 2 x 40 watts at a load of 4 ohms, and has inputs for four linear signal sources. The output stages of the amplifier operate in push-pull mode, and are built on 6550 JJ lamps in pentode mode.

The Octave V 16 Single Ended model is the company's first complete single-stroke amplifier. Thanks to the use of proprietary exclusive technologies, this device boasts powerful dynamics, low noise, high stability and wide bandwidth, which is usually not typical for standard single-stroke devices.
