Drawing upon nearly 60 years of tube amplifier design, the all-new AV (Analog Valve) Series from VOX offers players a full pallet of authentic amplifier sounds via eight, all-analog pre-amp circuits .VOX’s AV amplifiers also feature a true analog circuit design based on the classic 12AX7 tube, which lends classic, harmonically rich tones to these amps. The innovative Valve Stage section modifies the circuit to add, or reduce, brightness & bass response, and also allows users to adjust the bias and response of the power section on the fly. Additional features like a unique, sealed cabinet design, three classic effects (Chorus, Delay & Reverb), and a retro-inspired aesthetic establish the AV Series as one the most exciting, and unique, offerings in the VOX lineup.

The preamp circuit that decisively determines the character of the sound uses a completely analog design, and is constructed with a huge number of carefully selected resistors and capacitors. It is actually equipped with eight different analog 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.
n order to deliver true tube sound, there must be vacuum tubes. The AV series features a circuit design with two triode tube circuits that utilizes the classic 12AX7. The AV15 has only one 12AX7, but by using half of the dual triode in the preamp and the other half in the power amp, it delivers true tube operation for both preamp and power amp sections. The AV30/60 use two 12AX7 tubes, one for the preamp and one for the power amp, delivering an even more dynamic sound. The internally supplied voltage is 60V; this high voltage allows the potential of the vacuum tubes to be fully utilized, and lets you obtain natural and powerful distortion reminiscent of some of the most iconic tube amplifiers.
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 in. In spite of these obsessive specifications, sounds can be switched instantly, letting you enjoy a wide spectrum of variation.
The cabinet structure of the AV range has a major influence on the sound quality. The baffle and cabinet utilizes a one-piece construction, which allows for the vibration of the speaker to be supported by the entire cabinet, minimizing 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.
We have paid careful attention not only to the amp sound but also to the effect section. The AV series 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.
The AV series 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 AV30/60 provide 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.
You can use an optional foot switch to switch channels (AV30/60 only) or turn effects on/off. Using your foot to conveniently operate these functions is especially useful on stage.
