AC50/AC100 Classic Plus
Owner’s manual
INTRODUCTION
Thank you for buying the VOX CLASSIC PLUS amplifier. As you probably already know (otherwise you
probably wouldn’t have bought it!) these amplifiers are available in both 50 and 100 Watt variants. This
manual covers the operation and other details of both. Although the Classic Plus range is totally brand new
and up to date in design and features, you can be assured that there is 50 years of classic VOX sonic
history packed into every amplifier.
The Classic Plus is a channel switching valve pre- and power-amp guitar amplifier that can produce many
flavours of tone from pristine clean to impressive high-gains, and all points between. The two channels
have a variety of wide-ranging controls to help you create the sound textures that you require, and as the
controls of the two channels are totally independent, you do not need to compromise to achieve your
desired tonal palette.
In addition to the aforementioned controls, the amplifier features Spring Reverb with individual level control
for each channel with remote foot-switching, plus series FX looping with selectable level control and by-
pass switching. The extensive DI output facility has both balanced XLR and unbalanced jack outputs with
rotary level control and ground lift switching. To enable great sounding connection into PA or recording
equipment, the DI also features a speaker emulating Low Pass Filter (LPF) network. This can be switched
into or out of circuit as required. Another great plus of the DI circuit is that it is post the power amplifier’s
phase inverter valve, and before the Output Master Volume control. What this means is that no matter how
loud or quiet your stage level is, you have totally independent control of the DI output level. You can even
turn the Master Volume totally off and use the DI output for “silent” recording for those midnight sessions.
Even if you are an experienced amp tinkerer we really do suggest that you read this manual before turning
the amp on. There may be something in these pages that you didn’t know. Even if there isn’t, hopefully we
will have entertained you as you learn about your new CLASSIC PLUS.
After reading this manual, please plug in, turn on, and ROCK till you drop.
Thank you.
