The signing tone of a tube amp, the stunning presence ... there's a certain sound that can only be attained by analogue circuitry and by a tube amp in particular. While multi-voice tube amps do exist, they are few and far between, and hardly ever affordable.
The AV series is a new concept in tube amps, delivering versatile tube sound yet excelling in affordability. Featuring 12AX7 driven preamp and power amp sections, these amps feature eight distinct analogue preamp circuits that create eight types of tube sound ranging from transparently clean to crunchy chime and modern high-gain. Special attention was paid to the analogue design, which is painstakingly constructed from a staggering number of components. The classic tones of the AV range are further enhanced by a customisable tube equipped analogue power section and a unique, sealed speaker enclosure for improved resonance. Rounding out the feature set are three high-quality effects including Chorus, Delay & Reverb. These are perhaps the most revolutionary tube amps in all of VOX's long history.
Analogue Preamp Circuits That Provide Eight Distinct Sounds
The preamp circuit that decisively determines the character of the sound uses a completely analogue design, and is constructed with a huge number of carefully selected resistors and capacitors. It is actually equipped with eight different analogue preamp circuits. In other words, the AV series is able to accurately reproduce the sound of eight classic tube amps. In addition to the coveted AC30 top boost sound, it also covers a wide range of tones from clean to high-gain, including a sound that is reminiscent of the rare AC15 with EF86 tubes.
A 12AX7 Is Used For Both The Preamp And Power Amp
In order to deliver true tube sound, there must be vacuum tubes. The AV series features a circuit design with two triode tube circuits that utilises the classic 12AX7. The AV30 uses two 12AX7 tubes, one for the preamp and one for the power amp, delivering a dynamic sound. The internally supplied voltage is 60V: this high voltage allows the potential of the vacuum tubes to be fully utilised, and lets you obtain natural and powerful distortion reminiscent of some of the most iconic tube amplifiers.
Four Modes Modify The Circuit Response Of The Preamp And Power Amp Tubes
Four slide switches allow you to modify the response of the vacuum tube peripheral circuitry. For the preamp tubes, there are two switches: BRIGHT boosts the high frequencies, and FAT boosts the low end. For the power tubes, you can change the operating point of the vacuum tubes by using the BIAS switch to select either a clear and modern sound or an easily distorting vintage sound, and the REACTOR switch lets you vary the amount of feedback to the power amp, changing the damping factor to obtain a more dynamic, wide-ranging, and crisp sound. These changes can be made instantly, allowing you to modify the amp's response at will. In spite of these obsessive specifications, sounds can be switched instantly, letting you enjoy a wide spectrum of variation.
Vox have paid careful attention not only to the amp sound but also to the effect section. The AV30 is equipped with three high-quality effects: modulation, delay, and reverb. Each can be selected independently, giving you the freedom to shape your sound accordingly.
Revolutionary Cabinet Structure
The cabinet structure of the AV30 has a major influence on the sound quality. The baffle and cabinet utilises a one-piece construction, which allows for the vibration of the speaker to be supported by the entire cabinet, minimising unwanted vibration and more efficiently emitting the sound. Front-mounting the speaker also achieves a louder and clearer sound that's less directional and more spacious. In addition, the bass reflex design maintains the low range while delivering a more natural sound balance. It goes without saying that this clever design is another significant advantage of the VOX AV series.
Breathing New Life Into Conventional Tube Amp Design
The AV30 achieves functionality and expandability, both with a high degree of precision. The headphone amp features a version of the cabinet simulator used in products such as the amPlug series, with additional refinements that allow it to convey an even more detailed sense of airiness. Even when playing your guitar at home or at night, you can enjoy sound that overflows with realistic presence. The AUX input lets you connect an external audio source, and is equipped with a circuit that compensates for the response of the speaker and cabinet, allowing you to hear sound that's faithful to the original source.
The AV30 provides additional expansion potential with send/return jacks for convenient connection of compact effect units, as well as an external speaker output. With these features, you'll be able to take full advantage of the AV series' capabilities in a wide range of situations.
Optional Foot Switch Control
You can use an optional foot switch to switch channels or turn effects on/off. Using your foot to conveniently operate these functions is especially useful on stage.
