1.LOUDSPEAKERNever useOUTPUTSthe amplifier without a load attached!WARNING!

There are two parallel loudspeaker output jacks provided for connection to the internal speakers or extension cabinet. Please always ensure that the amplifier's output impedance selector is set correctly (see item 2) and ALWAYS ensure you use good quality speaker (unshielded) cables. NEVER use guitar (shielded) cables.

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

Matches2. OUTPUTthe amplifier’sIMPEDANCEoutput toSELECTORthe load (speaker) impedance.

Your 1987X-PW should be completely powered down before the Output Impedance Selector is turned.

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 cabinet(s) being used. The two internal speakers are 16 Ohms each.These are wired in

parallel giving an overall impedance of 8 Ohms; therefore the output selector should be set to 8 Ohms. If an additional 8 Ohm extension speaker cabinet is used in conjunction with the internal speakers the output selector should be set to 4 Ohms.

No additional extension speaker cabinet with impedanceNote: lower than 8 Ohms should be used in conjunction with the internal speakers.

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

If you do not know, consult your authorized Marshall dealer. Adjusting the selector from 230V to 120/100V or vice- versa will require the mains fuse (item 5) to be changed to the correct value as detailed on the rear panel.

With every 1987X-PW sold Marshall will make a sizable donation to the Childline charity. Providing help and support to those children who need it, Childline is a vital service and one that relies heavily on private donations to operate. It is with great pleasure that both Marshall and Paul Weller, through the creation of the 1987X-PW, have agreed to support a charity that has such a positive effect on those who turn to it.

1987X-PW specifications

Marshall Amplification is a name synonymous with rock music, and the Marshall 1987X-PW stands as a testament to their legacy of powerful and remarkable sound. Known for its classic design and exceptional performance, the 1987X-PW is a part of Marshall's 1959SLP reissue series and is celebrated by guitarists around the world for its ability to deliver that iconic Marshall tone.

The 1987X-PW is a 50-watt, all-tube head that typically generates rich, harmonic overtones, making it a staple in both studio and live environments. It is equipped with four EL34 power tubes, providing a warm and dynamic tone at various volume levels. The amplifier’s dual channel configuration allows players to switch between a crisp clean sound and a thick, saturated overdrive, perfect for a wide array of musical styles.

One of the standout features of the 1987X-PW is its classic British sound, characterized by a strong midrange presence and articulate highs. The four inputs offer greater versatility, allowing for different sonic characteristics depending on how they are utilized. Players can achieve everything from subtle chime to aggressive crunch, giving guitarists the ability to tailor their sound to perfection.

In terms of technologies, the 1987X-PW incorporates Marshall's time-honored circuit design, which plays a pivotal role in its tonal qualities. The hand-wired construction ensures durability and superior reliability, making it a favorite among discerning musicians.
