Marshall 1960B Straight Extension Cabinet

GETTING STARTED

• Congratulations on purchasing your Marshall cabinet.
• Our cabinets are designed with you in mind, with each speaker specially selected for its tone and each unit lovingly crafted.
• We’ve got over 50 years’ worth of experience and this allows us to deliver meticulously planned, high-quality products.
• From major international festivals and multi-million-pound recording studios to local bars and bedroom band practice, our cabinets are built to stand the test of time and fulfil all your performance needs.

4×12″ mono/stereo switching facilities

To ensure maximum flexibility, some of our 4×12″ cabinets boast a mono/ stereo switching system on the back.  When ‘stereo’ mode is selected, the cabinet is split into two 852 ‘halves’ for use with a stereo amp.  When ‘mono’ is selected you are offered two different impedance inputs (492 or 1652) to choose from.  Always ensure you select the correct one to match the impedance of your amplifier and never use both inputs at the same time when the cabinet is in ‘mono’ mode.

1. Mono/stereo selection switch. Select either stereo or mono mode.
2. Right input.
   • When the switch (1) is set to:
   1. Stereo, this provides a connection to the right* side pair of speakers. Rated at 892.
   2. Mono, provides a connection to all four speakers. Rated at 452.
3. Left input.
   • When the switch (1) is set to:
   1. Stereo, this provides a connection to the left* side pair of speakers hated at 892.
   2. Mono, provides a connection to all four speakers. Rated at 1652.

Right and left refer to the two stereo sides of the cabinet as seen when facing the front of the cab.

2×12″ stereo selection facilities

Some of our 2×12″ cabinets are fitted with a mono/stereo selection plate on the back. This enables you to split the cabinet into two halves for use with a stereo set-up if you desire.

• Mono usage: Use the input marked mono (1), the impedance of which is indicated above the jack.
• Stereo usage: Use both inputs (1 and 2). Once again the impedance of each is marked.

Single mono input

• Some cabinets are fitted with a single mono input socket. With this cabinet, the impedance and power rating are fixed.
• Use a suitable speaker cable to plug your guitar amplifier into this socket.
• Ensure the impedance and power handling of the cabinet is compatible with your chosen amplifier.
