things in life, it is worth investing some time

playing around until you find the desired sweet

spot!

Note: The amp’s Master Presence control (17)

affords you further adjustment of the high end.

7. OD1 Channel Select Switch

Pressing this front panel switch selects the

Overdrive 1 (OD1) channel of your AVT.

8. OD1 Gain Control

This rotary control can be best described as the

‘sonic brain’ of the OD1 channel. Lower Gain

settings will produce well-defined, natural

sounding overdrives which have a nice ‘cut,’

making them perfect for funky, blues rock.

Higher gain settings will see the sound start to

get more ‘rounded’ as the AVT’s pre-amp valve

is pushed into saturation.

9. OD1 Scoop Switch

Fine tuned to create the most awesome mid

‘scoop’ imaginable, OD1’s Scoop circuitry is

more than just a pre-set middle control. Instead

it actually reconfigures the whole post-EQ

voicing of the channel - from low to high.

Because of this, even though the resulting

‘scooped’ sound that occurs when the switch is

activated (pushed ‘in’) is totally extreme, the

channel’s overall tone still remains tight and

focused.

10. OD1 Volume Control

As its name suggests, this control determines

the volume of the OD1 channel. The actual

setting you choose will be dependent on how

loud you want the channel to be, and also on

the type of sound you have selected on the pre-

amp (i.e.: high Gain settings will generate much

more preamp output level than lower, cleaner

sounding Gain settings).

Due to the remarkable realism of our Advanced

Valvestate Technology, once the Volume control

is turned-up past a certain point, the preamp will

start to push the power amp section into

creating its own, desirable distortion - just like

an all-valve Marshall amp. When this occurs, the

AVT’s power amp will start to add musical

harmonics, compression and desirable ‘break-

up’ to your sound.

As previously stated, each channel has its own

volume control so you can easily balance the

levels of all three channels. Once set to your

satisfaction, these controls can be left alone and

you can use the amp’s Master Volume knob (16)

to set your overall volume level to best suit each

playing situation and venue.

11. OD2 Channel Select Switch

This selects the Overdrive (OD2) channel of

your amp.

12. OD2 Gain Control

Cranking the OD2 Gain control will unleash the

most extreme gain levels ever found on a

Marshall Valvestate amplifier. The higher

settings of the OD2 gain control can be likened

to driving the front-end of an already raging

Marshall valve amp with a high gain, overdrive

stomp box. If you’ve already experienced the

tonal pleasure of ‘front ending’ a Marshall valve

amplifier in this way, you will appreciate the

energy and dynamics of this type of set-up!

Turning the OD2 Gain control clockwise will see

more of the already smouldering signal being

sweetly compressed and ‘rounded’ by the

unique characteristic of the AVT’s Valve Drive

stage as it is driven over the top into total

saturation. This channel can also be as nasty

and ‘in-yer-face’ as you would like. Engaging the

OD2 ‘Scoop’ button (13) will take this channel

onto a new level of cranium crushing crunch,

perfect for modern (a.k.a. ‘nu’) metal.

13. OD2 Scoop Switch

As is true of the OD1 Scoop, this circuit acts like

an advanced, pre-set contour control that not

only ‘scoops-out’ the mids but also shapes the

highs and lows for a tight, focused sound.

Engaging OD2’s Scoop Switch loads you up

with a ‘bottom heavy’ sound perfect for the de-

tuned, high-gain aggression favoured by many

modern acts.

14. OD2 Volume Control

This control regulates the drive of the OD2

channel into the power stage of the amplifier,

hence controlling its output volume. You will find

that the louder you go, the looser the bottom

end of your sound will become. Having said this,

the closed-back cabinet design of your AVT is

such that it will deliver tight, well-defined low

end at much higher volumes than any other

‘hybrid’ amplifier known to man.

15. Overdrive Tone Controls

Your AVT is equipped with rotary Bass, Middle,

and

reble EQ controls which are shared

between the two Overdrive Channels, OD1 and

OD2.

This EQ section boasts a tone circuit

identical to the one used in legendary Marshall

valve amplifiers such as the 100 Watt ‘Plexi’ and

the JCM800 2203, making it a foundation stone

for that instantly recognisable and

unsurpassable ‘Marshall Sound.’ As was the

case with the Clean channel’s EQ network,

these controls are interactive and, as a result,

allow endless tonal possibilities.

Note: Remember that in addition to these three

controls, further tonal adjustment is also

afforded by the Scoop button (13) and also the

Master Presence control which is explained later

(17).

II. The Master Section

These controls adjust the power amp section of

your AVT and determine the overall Volume and

Presence of the amplifier.

16. Master Volume

Once you have set the relative volumes of your

AVT’s channels, this control governs the overall

volume of the amplifier.

17. Master Presence

A feature normally only found on expensive

valve amplifiers, the Presence control affords

you increased high frequency control by altering

the power amplifier’s feedback. Increasing the

Presence control will emphasise high-end ‘fizz’

in overdriven tones and top-end ‘sparkle’ in

clean sounds.

lII. FX Section

A. Parallel FX Loop

Your AVT boasts a rear-panel mounted Parallel

FX loop for use with external effects devices.

This FX loop is Mono so if using a stereo effects

processor you would need to connect to the

‘mono’ output on the processor.

18. FX Loop Mix Control

(Clean & Overdrive)

When an effects unit is hooked-up to the

aforementioned FX loop, this control adjusts the

FX Mix for all three channels. Turning it

clockwise increases the amount of effect you

hear - from ‘dry’ (0) to ‘wet’ (10).

Please note that the FX mix on your external

processor should be set to maximum (i.e. ‘wet’).

B. Internal Digital FX

As mentioned in the introduction of this manual,

the AVT100X features a DFX (Digital Effects)

section which adds digital effects to all three

channels.

The DFX section boasts 16 on-board effects and

three controls - DFX Mix, Adjust and Program.

We chose these particular effects algorithms to

give you a comprehensive palette of natural

sounding options. When developing the DFX

section, our aim was to enhance the overall

sound of the amplifier and, most importantly,

allow the effects to work with you instead of

masking your all-important tone underneath

layers of artificial sounding digital signal

processing.
