AC30VR FRONT PANEL FEATURES
1 2 3 4
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.
