IMPORTANT SAFETY INSTRUCTIONS

• Read these instructions.

• Keep these instructions.

• Heed all warnings.

• Follow all instructions.

• Do not use this apparatus near water.

• Mains powered apparatus shall not be exposed to dripping

or splashing and that no objects filled with liquids, such as

vases, shall be placed on the apparatus.

• Clean only with dry cloth.

• Do not block any ventilation openings. Install in

accordance with the manufacturer’s instructions.

• Do not install near any heat sources such as radiators,

heat registers, stoves, or other apparatus (including

Welcome to VOX

Many thanks for adding the VOX AC30VR/AC15VR amplifier to your sonic arsenal.

It was designed by our UK based VOX engineering team and built by our state of the art, vertically integrated manufacturing facility

and we’re sure it’ll give you countless hours of great guitar tones that will feel as good as they sound! To insure a long and happy

relationship with your amplifier, please read this manual at least once, and (as they say), “use the product as directed.” Keep the

manual for future reference after you’ve read it.

WHAT IS VR?

The VR series of amplifiers are designed, as to what we

believe are the next generation of “hybrid” guitar amplifiers.

What does HYBRID mean, you may ask? Well, basically

“hybrid” means that it utilizes a mixture of technologies—in

this case those technologies are Tube and Solid State.

The Preamp stages consist of discrete transistors for sound

generation, and integrated circuits (op-amps) to do signal

management that would not be done effectively with transis-

tors alone—i.e. channel switching, etc.

The Power amp stage uses a 12AX7 vacuum tube (or valve,

depending where you live in the world) in a configuration that

we at VOX call Valve Reactor.

The patented Valve Reactor power amp technology is used in

all Valvetronix products. It was originally designed for the

award winning VOX Valvetronix modelling guitar amplifier

range, and now we have taken that same technology and fur-

ther revised it into the format that is built into your AC30VR/

AC15VR amplifier.

HOW DOES IT WORK?

It basically works by having each half of the 12AX7 (the

12AX7 tube is actually two identical tubes in one glass tube

a.k.a. dual triode) and configuring it to work as a small tube

power amplifier. This circuit provides all the tonality and feel of

an all-tube power amp. Obviously this “small” power amp

would not be very loud if it was connected directly to a loud-

speaker—therefore the tube circuit is connected to a larger,

completely transparent solid-state power amplifier, that is run

very cleanly so that it does not add its own colouration to the

tube signal.

This power output amplifier also has some special circuits that

feed the loudspeaker impedance information back to the tube

power amplifier in order to give it the loose sound & feel that

an all-tube amp does.

SO WHAT DOES THIS MEAN?

We think that the VOX VR amplifier range brings you superb

tone (vintage & modern) that includes the high harmonic con-

tent and compression that goes all the way back to the original

VOX AC15 & 30 amplifiers that were created more than 50

years ago, and are still revered to this day.

AC30VR FRONT PANEL FEATURES

1. MAINS POWER SWITCH

Turns your AC30VR OFF/ON from the connected mains

power.

2. POWER LED

Illuminates RED when your amplifier is switched on, and is

also connected to a suitable mains power supply.

MASTER

3. VOLUME

This controls the amount of volume produced by the

AC30VR’s Valve Reactor power amplifier circuit, and there-

fore the overall volume that your AC30VR supplies to any of

the loudspeaker systems that are connected.

4. REVERB

This controls the amount of digital reverb that is mixed with the

direct signal to produce a slight shimmer of reverb (low set-

tings) to concert hall depth (at high settings).

The built-in digital reverb can be cancelled or activated by the

optional VFS2 Dual Footswitch. (Channel-Reverb)

5. TONE CUT

This circuit is placed in the power amp as opposed to the pre-

amp section like the Treble and Bass controls. What this does

is the opposite of what you may think. Turning it clockwise will

decrease the higher frequencies and turning it counterclock-

wise adds higher frequencies.

OVERDRIVE CHANNEL

6. TREBLE CONTROL

This controls the amount of TREBLE in the Overdrive channel.

7. MIDDLE CONTROL

This controls the amount of MIDDLE frequency in the Over-

drive channel.

8. BASS CONTROL

This controls the amount of BASS in the Overdrive channel.

9. VOLUME CONTROL

This controls the amount of overdrive generated by the pre-

amp signal that is sent to the Valve Reactor power amplifier.

Use this to set the loudness required for your use, and also to

balance the overdrive sound against your clean (Normal)

sound.

10. CHANNEL SELECT LED

Illuminates RED when the Overdrive channel is selected.

11. GAIN CONTROL

This regulates the amount of preamp “gain” and therefore the

amount of overdrive or distortion that is generated by the

Overdrive Channel. Like the Normal Volume control, lower

settings mean less distortion, higher settings mean much,

much more distortion!

12. OVERDRIVE STYLE BUTTON

This button changes the distortion characteristics (STYLE) of

the Overdrive channel—OUT=OD1, IN=OD2.

OD1 is a warm natural “vintage” overdrive flavour, ideal for

“blues” based sounds.

OD2 is a harder, more aggressive, high gain style distortion,

more suited to “modern” playing.

13. CHANNEL SWITCHING BUTTON

This button controls whether your amplifier is set for Normal or

Overdrive—OUT = NORMAL, IN = OVERDRIVE.

Your AC30VR can also be channel switched by using the

optional VFS2 Dual Footswitch (connected via the back panel

Footswitch Jack). This function can only be operated when the

front panel button is “IN” position.

When the Normal channel is selected, the LED is not illumi-

nated—when the Overdrive channel is selected, the Red LED

is illuminated.

NORMAL CHANNEL

14. TREBLE CONTROL

This controls the amount of TREBLE in the Normal channel.

15. BASS CONTROL

This controls the amount of BASS in the Normal channel.

16. VOLUME CONTROL

This controls the volume of the clean (NORMAL) channel. At

lower settings the sound will be very clean and bright, at

higher settings the sound will become somewhat thicker and

warmer, whilst at the highest settings the sound will “break up”

into a natural vintage style distortion.

As different types of electric guitars have vastly different

amounts of tonal qualities and output levels, your guitar will

have a major influence on where you will need to set the posi-

tion of the controls on this amplifier to achieve the response

you desire.

Please Note—for this control to be functional the

amplifier channel switching facility needs to be set to

the Normal channel.

17. INPUT JACK

Connect your guitar into this socket.

REAR PANEL FEATURES

1. FOOTSWITCH JACK

2. EXTERNAL SPEAKER OUTPUT JACK

An external loudspeaker system can be connected to your

amplifier by using this socket. This socket disconnects the

amplifier from the internal loudspeaker.

WARNING! To ensure that your system works cor-

rectly, you must observe the following points.

a) Only use an external cabinet with a combined

impedance of 8ohms.

b) Don’t connect a speaker whose rated input capac-

ity is less than 15 watts (for AC15VR) or 30 watts (for

AC30VR). The speaker may be destroyed if you

ignore this caution—not recommended!

c) You must use a speaker cable to connect an exter-

nal speaker. Don’t use a shielded cable like the one

you use to connect a guitar to an amp.

d) You must turn off the power before connecting the

cable. Connecting the cable while the power is turned

on may damage your amp.

3. MAINS POWER CONNECTOR/FUSE

The mains power required by your amplifier is connected

using this device.

WARNING! Use only the power cord supplied with

your amplifier, or a replacement of the exact same

specification.

WARNING! Only connect this amplifier to a suitable

mains power supply that matches the rating indicated

on the back panel of your AC30VR/AC15VR ampli-

fier. IF IN ANY DOUBT CONTACT YOUR DEALER!
