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. ENGLISH
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.
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).
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.
7. OD1 Channel Select Switch
Pressing this front panel switch selects the Overdrive 1 (OD1) channel of your AVT.
ENGLISH
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.
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�).
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.
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.
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.
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.
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.
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 detuned, high-gain aggression favoured by many modern acts.
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 preamp (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 �breakup� 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
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 Treble 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
