User manual MARSHALL EXT. CABINETS 1960

[. . . ] Many of our cabinet construction techniques have changed very little since the Guv'nor, Jim Marshall, hand-built his very first cabinet back in 1962. We still use the finest materials available and build all our cabinets to truly stand the test of time. We also carefully select the loudspeakers that best suit the particular purpose for which each cabinet is intended and test them exhaustively for optimum performance. [. . . ] Servicing is required when the speaker cabinet has been damaged in any way, such as liquid being spilled or objects falling into it, the speaker cabinet being exposed to rain or moisture, the speaker cabinet not operating normally or being dropped or damaged in any way. Ensure all associated equipment is switched off and unplugged from the mains before connecting or disconnecting the speaker cabinet. Always Plug the speaker lead into the speaker cabinet before plugging it into the amplifier. Ensure any associated equipment is switched off and unplugged from the mains in the event of lightning storms or if unused for long periods of time. Always ensure that the supplied speaker lead is used to connect the speaker cabinet to associated equipment. Protect the speaker lead from being walked on, pinched or having heavy objects rolled over it. Ensure the speaker lead is not entangled with any other lead. If a replacement speaker lead is required please contact your authorised Marshall Dealer. If the speaker cabinet has switchable impedance, please ensure that the correct impedance is selected and that any associated equipment impedance settings are also correctly set. If the speaker cabinet has mono/stereo switching capability, ensure that the switch is in the correct position for the desired operation. Always move or transport speaker cabinets individually. Never attempt to move or transport speaker cabinets if they have other cabinets or associated equipment stacked on or under them. Always ensure that the speaker cabinet is on a level surface, whether used or stored individually, or as a speaker cabinet stack, and/or with associated equipment placed underneath or on top. 4x12 Mono/Stereo Switching Facilities (1960A, 1960B, 1960AV & 1960BV). To ensure maximum flexibility, four of our 4 x 12 cabinets boast a Mono/Stereo switching system on the back. When `Stereo' mode is selected, the cabinet is split into two 8 Ohm `halves' for use with a stereo power amp (e. g. : EL34 100/100, EL34 50/50, EL84 20/20, 8008 or VS 120/120) such as used in a rack system. [. . . ] If you are unsure, contact your authorised Marshall Dealer.

Caution: Any changes or modifications not expressly approved by the party responsible for compliance may void the users authority to operate the equipment. 2x12 Stereo Selection Facilities Some of our 2x12 cabinets are fitted with a Mono/Stereo selection plate on the back.
