Apart from the vital valve tone this ingenious power amp design provides, it also
allows us to replicate various “circuit characteristics” that are unique to the all-valve
power stages of the amps we’ve modelled. These “characteristics” include: Class A or
Class AB operation, Presence and Resonance (low end) control circuitry (both found in
the negative feedback circuit that some, but not all, valve power amps have) and power
output. Being able to match such vital characteristics helps ensure that each and every
one of our models is as tonally authentic as possible — as opposed to the usual “close
but no cigar” norm of digital modeling. And just so you know, this patented in USA power
amp technology is unique to VOX Valvetronix.
Quick Start
nce you’ve satisfied your primal urge to play, I’d like to urge you to give this man-
ual a chance — it’s been written by a fellow guitar nut and this amp boasts some
killer bells ‘n’ whistles that warrant your interest. In short, it’ll be worth your while,
we promise. This said, here’s the “Quick Start” — enjoy! I look forward to taking you
through the amp in more detail once you’re done...
HINT:
If you’re not sure of the location of a control or switch referred to in this Quick Start
section, you can refer to the illustrations in the section entitled “The Guitarist’s Guided
Panel Tour” (page 8).

1. Turn the MASTER volume control on the amp all the way down.
2. Plug one end of the supplied power cord into the AC power connector on
the rear panel, and plug the other end into a wall outlet.
3. Plug your guitar into the INPUT jack on the top panel.
4. Turn on the POWER switch.
5. Slowly raise the MASTER volume to adjust the volume.
HINT:
The rear panel POWER LEVEL control controls the output level of the power amp,
letting you adjust the volume while keeping that great-sounding power-amp distortion!
(The AD15VT-XL doesn’t have this feature.)
NOTE:
You won’t hear any sound for a few seconds while the valves warm up. This isn’t a
malfunction, this is how a tube operates normally.
