1. SPEAKER OUTPUTS
1/4" jack speaker outputs. They are labelled
according to the intended impedances:
• 1 x 16 Ohm: connect a 16Ω guitar cabinet.
• 1 x 8 Ohm / 2 x 16 Ohm: connect a single
8Ω guitar cabinet or two 16Ω cabinets.
• 1 x 4 Ohm / 2 x 8 Ohm: connect a single 4Ω
guitar cabinet or two 8Ω guitar cabinets.
Warning: never attempt to connect speaker
combinations that do not match the impedance
options on the amp. The safe combinations are
those listed. Any other speaker combinations
may stress the power amp and potentially lead
to valve failure. Do not use this amp without a
speaker load.
2. DI OUTPUT
A DI output allows you to connect to a
recording device or sound desk.
Note: using the DI does not omit the need for a
speaker to be connected.

mains electricity supply please seek help from
a qualified engineer – your Marshall dealer can
help you with this.
