19 DFX Mix Control	22 Digital FX Program/
(Clean & Overdrive FX)	Adjust Table

1Mains Input Connector

Your AVT is provided with a detachable

used in both live performance and recording situations to achieve authentic guitar amp tones, without having to use a microphone.

This determines the level of the internal effects selected by the Program control (21). In general you will find that the modulation effects (e.g.: Chorus, Flange) require more level than the reverbs and delays. As always, let your ears decide what is right!

20Adjust Control

(Clean & Overdrive FX)

For each of the 16 selectable DFX a particular parameter is adjustable. For example, when a Reverb is chosen, the decay (how long the reverb will be heard before it fades away) is adjustable via this control. The ‘Program/Adjust’ table (22) on the front panel of your amp lists what the Adjust control does for each of the 16 programs.

This lists the 16 programs selectable via the Program control (21) and also indicates which parameter the Adjust control (20) modifies for each one. For added convenience, this table is shown below.

	Program		Adjust
	Halls	1 - 3	Decay Time
	Rooms	4 - 6	Decay Time
	Plates	7 - 9	Decay Time
Gated reverb		10	Decay Time
	Chorus	11	Rate
	Flange	12	Rate
	Delay		Time

mains (power) lead which is connected here. The specific mains input voltage rating that your amplifier has been built for is shown on the back panel. Before connecting for the first time, please ensure that your electricity supply is compatible with your amplifier. If you have any doubt, please seek advice from a qualified technician. Your Marshall dealer will help in this respect.

2Loudspeaker Jack Sockets

There is one speaker jacksocket on the AVT100, marked Internal (8 Ohm), this is where the output of the AVT power amplifier is connected to its internal 8 Ohm Celestion loudspeaker.

Turn down the Master Volume (16) for silent recording.

FX Loop

As already mentioned, the AVT100 boasts a Mono Parallel FX loop for connection with external effects units. In addition to the FX Mix control on the front panel (see ‘Front Panel Features,’ point 18) this FX loop comprises of an FX Send jack, an FX Return jack and an FX level control button.

6FX Return

For connection to the output of your external effects device.

21Program

(Clean & Overdrive FX)

This selects each one of the 16 on board digital effects. The DFX available include single effects such as Reverb (9 types), Delay or Chorus and also multi-FX such as Chorus/Delay/Room. To add further to the flexibility of the DFX sections it can be switched on and off via the sturdy, 4 way foot- controller which comes supplied with each amp.

	13
Chorus/Room	14	Decay Time
Ch/Dly/Room	15	Time
Modulation	16	Speed

23Power Switch

Wait for it...yes, this switches the amp on and off! When the amp is on the power switch is illuminated and vice-versa. Advanced power amplifier muting circuitry provides anti-thump protection on power up and down.

Important Note: As is the case with an all- valve amplifier, there will be no signal heard until the amp’s ECC83 preamp valve warms-up and starts to pass signal. This can take up to 15 seconds so don’t panic!

!WARNING:

Always provide the AVT100 with a load equal to, or greater than, 8 Ohms.

3Footswitch

For connection of the supplied Stage Foot Controller (PEDL-00030). This sturdy 4-way Marshall footswitch allows instant selection of the 3 channels, plus the DFX. It also features LED's to indicate status.

4Headphone

The headphone output is fully emulated using an improved version of the circuitry found on the industry standard JMP-1. Turning the Master Volume (16) to zero will provide silent practice.

5Emulated Line Output

This jack socket carries a specially treated output signal from your AVT that accurately emulates the sonic signature of a Marshall 4x12 cabinet. This unerringly accurate emulation circuitry is Marshall's most advanced to date and was developed via countless hours of technical research, playing, listening and fine-tuning. This output can be

7FX Level

This should be set to match the level of the processor being used (generally -10dB for a stomp box, + 4dB for a professional, rack unit).

8FX Send

For connection to the input of the external device being used.

➲FX Loop Hints

a)Always use high quality, shielded patch

cables.

b)If the processor being used has an input level control, ensure it is set correctly.

c)Time based effects (delays & reverbs) and modulation effects (chorus, flange, phase, etc.) are ideal for use in a Parallel FX loop.

d)Certain stomp box effects such as Wah, distortion, overdrive and fuzz were designed specifically for use in-front of the amp and sound best when used that way. This said, tonal beauty is in the ears of the beholder so, if such a pedal sounds great to you when used in an FX loop then go for it! Sometimes, there are no rules...
