1. LOUDSPEAKER OUTPUTS

There are two parallel loudspeaker output jacks provided for connection to speaker extension cabinet(s). Please always ensure that the amplifier’s output impedance is set correctly (item 2).

WARNING! Never use the head without a load attached!

Always use a non-screened Marshall approved speaker lead when connecting an extension cabinet to these units.

3. H.T. FUSE

The correct value of H.T. fuse is specified on the rear panel of the amplifier. NEVER attempt to bypass the fuse or fit one of the incorrect value.

4. MAINS INPUT

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

LEAD CHANNEL

3. TONE CONTROL

This adjusts the tonal character of the Lead Channel. Turning this control clockwise increases the amount of high frequencies (treble) in the sound.

Because both Channels of the 2061X have the same number of gain stages (one) and are therefore in phase with each other, it is possible to bridge them together (a.k.a. ‘slaving’, ‘jumping’, ‘linking’ or even ‘daisy-chaining’) and use them both at the same time, enabling you to expand upon the amps tonal possibilities by mixing the Lead and Bass channels together.

Matches the amplifier’s output to the load (speaker)

impedance.

As is the case with any Marshall all-valve amplifier it is imperative that: a) the amplifier is connected to a load whilst in operation and b) the impedance selected on the amplifier matches the total impedance of the extension speaker cabinets being

respect.

5. MAINS FUSE

The correct value of mains fuse is specified on the rear panel of the amplifier. NEVER attempt to bypass the fuse or fit one of the incorrect value.

4. VOLUME CONTROL

This controls the volume of the Lead Channel. Turning it clockwise increases the volume level of the channel.

5. LEAD CHANNEL INPUTS

These are the guitar inputs for the Lead Channel. The top input is ‘high sensitivity’ and the bottom input is ‘low sensitivity’, the latter being 6dB lower in volume than the former with a darker sound. Always use a high-quality, screened guitar lead.

BASS CHANNEL

The most common way of doing this is to plug your guitar into the top (high sensitivity) input of one of the two channels and then run a short ‘jumper’ guitar cable (i.e. a screened cable) from that channel’s bottom (low sensitivity) input to one of the other channel’s two inputs.

It is also possible to plug your guitar into the bottom (low sensitivity) input of one of the two channels and then run the ‘jumper’ cable from its top (high sensitivity) input to one of the other channel’s two inputs. This less-common approach can also yield some interesting tonal variations.

used.

WARNING! An extension speaker cabinet with an impedance of less than 4 Ohms, or two extension cabinets of 4 Ohms or less should NOT be used with this head.

The amp should be completely powered down before the Output Impedance Selector is turned.

Failure to comply with any of the points raised in this section will result in damage to the amplifier.

6. TONE CONTROL

This adjusts the tonal character of the Bass Channel. Turning this control clockwise increases the amount of high frequencies (treble) in the sound.
