1. LOUDSPEAKEROUTPUTS

WARNING! Never use theamplifier without aload

attached!

provided for connection to theinternal speakers or

extension cabinet. Please alwaysensure thatthe

amplifier's outputimpedance selectoris set correctly

(see item2) andALWAYS ensure you use good quality

speaker (unshielded) cables.NEVER use guitar(shielded)

cables.

Alwaysuse a non-screened Marshallapproved speaker

lead whenconnecting an extension cabinetto these

2. OUTPUTIMPEDANCESELECTOR

Matches theamplifier’soutput to the load (speaker)

impedance.

Your 1987X-PW should be completely powered down

before the Output ImpedanceSelector is turned.

As isthe case with any Marshallall-valveamplifierit is

imperative that:a) the amplifieris connected to aload

whilst inoperation and b) theimpedance selected on

the amplifiermatches the totalimpedanceofthe

extension speaker cabinet(s) beingused.The two

internal speakers are 16Ohms each.These arewired in

parallel givingan overall impedance of8Ohms;

thereforethe outputselector should be setto 8 Ohms.

If anadditional 8 Ohmextension speaker cabinetis used

in conjunctionwith theinternalspeakers theoutput

selector should beset to 4Ohms.

Note: No additional extensionspeaker cabinetwith

impedance lower than 8Ohms should be used in
