FRONT PANEL FUNCTIONS

POWER SWITCH
Turns the amp on and off.
STANDBY SWITCH
The standby switch is used in conjunction with the power switch to 'warm up' the amp before use.
Always turn the power on for two minutes before switching the standby switch to the 'on' position.
The standby switch should be set to the 'off' position during breaks in performances instead of leaving the amp on full power.
INDICATOR
The power indicator will light when the amp's mains power is switched on.
SPEED
Controls the speed at which the 'tremelo' effect oscillates.
INTENSITY
Controls the depth of the 'tremelo' effect's oscillation.
Note: 'tremelo' will only work when playing through channel 2.
PRESENCE
Adjusts the high frequencies of the power amp. Increasing the high frequencies adds more bite to your sound.
BASS
Adjusts the low frequencies of the amp. It will add bottom end and depth to your sound.
MIDDLE
Adjusts the mid frequencies of the amp, giving you anything from scooped mids to a fat and full sound.
TREBLE
Adjusts the upper frequencies of the pre-amp. Your tone will get brighter as it is turned up.
VOLUME I
Controls the overall output level of channel 1. This channel is for a higher treble response than channel 2.
VOLUME II
Controls the overall output level of channel 2. Channel 2 is voiced for normal response and has a more rounded tone than channel 1.
INPUTS
1 (Top): Connects the guitar to channel 1.
1 (Bottom): Connects the guitar to the lower sensitivity input on channel 1. 2 (Top): Connects the guitar to channel 2. 2 (Bottom): Connects the guitar to the lower sensitivity input on channel 2.
Note: some guitar players prefer to mix the two channels together by connecting a short, screened patch lead between the bottom input of channel 1 and the top input of channel 2. If you then plug your guitar into the top input of channel 1, you can mix the different tonal characteristics of each channel.

REAR PANEL FUNCTIONS

1. FOOTPEDAL
For connection of the supplied footswitch to allow 'tremelo' to be switched on and off.
Note: the 'tremelo' effect will only work when playing through channel 2.
& 3. SPEAKER OUTPUTS
Connect one or two speaker cabinets here using 1/4" jack speaker cables.

always ensure the output impedance selector is set to the appropriate impedance for the load of your setup (speaker cabinets). Never use this amp without a speaker or load.

OUTPUT IMPEDANCE SELECTOR
Matches the amp's output to the load impedance. Ensure the amp is completely powered down before turning the selector.
The impedance selected on the amp must match the total impedance of the speaker cabinet(s) being used:

The 1962 has two 16Ω speakers that together create an 8Ω load. Therefore if the internal speakers are being used on their own the selector should be set to 8Ω.
The internal speakers can be used with an 8Ω extension cabinet to create a load of 4Ω.
If the internal speakers are disconnected and the amp is running into a single 16Ω cab, the selector should be set to 16Ω.
If the internal speakers are disconnected and the amp is running into two 16Ω cabs, the selector should be set to 8Ω.
If the internal speakers are disconnected and if running into two 8Ω cabs, the selector should be set to 4Ω.

failure to comply with these points may damage the amp.

H.T. FUSE
The correct value of H.T. fuse is specified on the rear panel.
POWER INLET
The supplied mains power lead is connected here. The mains input voltage rating that your amp has been built for is shown on the rear panel.
MAINS FUSE
The correct value of mains fuse is specified on the rear panel.

WARNING! SAFETY INSTRUCTIONS

Please read this manual carefully before plugging in. Follow all instructions and heed all warnings.

please refer to full details in separate

Safety Instructions leaflet (document number CATS-00158).

MAINS ELECTRICITY SUPPLY AND OUTPUT IMPEDANCE
The specific mains input voltage rating that your amp has been manufactured for is indicated on the rear panel of the amp. Your amp is provided with a detachable mains (power) lead, which should be connected to the mains input socket on the rear panel of the amp.
The correct value and type of mains fuse is specified on the rear panel of the amp. Never attempt to bypass the fuse or fit one of the incorrect value or type.
The output impedance selector should be set to the total impedance of the speaker cabinet(s) (or load) being used.
If you have any doubt regarding your mains electricity supply or the impedance of speaker cabinet(s), please seek help from a qualified engineer – your Marshall dealer can help you with this.

your amp must be switched off and disconnected from the mains electricity supply before you:

check and/or change any fuse; and/or
change the output selector for a different setting.

Failure to comply with any of the points above may damage your amp.

IMPORTANT SET UP INFORMATION

Set the output impedance selector to the impedance of the combined load of the speaker cabinet(s) you will be using.
Check that the internal speaker and/or extension cabinets that you want to use are plugged into the speaker outputs correctly.
Note: There are two parallel speaker output jack sockets provided for connection to the internal speaker and/or an external load, e.g. speaker extension cabinet(s). The amp is supplied with the internal speaker connected to one of the speaker output jack sockets. More information on impedance can be found later in this guide.

failure to do the above may damage your amp. When connecting a speaker cabinet make sure that you use a proper speaker cable. Never use a screened (shielded) guitar cable for this purpose.
Ensure that both the power switch and standby switch are set to the off position.
Connect the supplied mains (power) lead into the power inlet on the rear panel first and then into an electricity outlet.
Ensure that any master, volume and/or output level controls on the front panel are set to zero.
Plug your guitar into one of the inputs on the front panel.
Turn the power switch on and wait a couple of minutes.
Turn the standby switch to the 'on' position.
Turn the volume up to your preferred level and you're ready to play.

TRANSPORTING YOUR EQUIPMENT
Please ensure that your amp is switched off, unplugged from the mains electricity supply and all removable cables have been disconnected from your equipment before attempting to move it.
