WARNING!
PLEASE READ THE FOLLOWING LIST CAREFULLY.
A. ALWAYS Ensure that a good quality mains plug conforming to the latest BSI standards is
fitted-(UK only).
B. ALWAYS wire the plug in accordance with the colour code attached to the mains lead (UK
only).
C. DO NOT attempt to remove the amplifier chassis. There are no user serviceable parts inside.
D. ALWAYS have this equipment serviced or repaired by competent, qualified personnel.
E. NEVER under any circumstances, operate the amplifier without an earth.
F. NEVER use any amplifier in damp or wet conditions.
G. ALWAYS ensure that the impedance of the speaker or speakers connected does not fall
below the amplifiers minimum impedance rating.
H. NEVER obstruct the ventilation grills.
I. ALWAYS use correct type of speaker leads when using extension cabinets.
J. PLEASE READ this instruction manual carefully before switching on.
Constant exposure to the high sound pressure levels of which this amplification system is capable could
result in permanent damage to your hearing.
Although individuals will vary in their susceptibility to noise induced hearing loss,
almost everyone will have their hearing impaired if exposed to intense sound levels for a
sufficient length of time.
To prevent the occurrence of permanent hearing loss, it is advisable to wear ear plugs or
protectors if you are going to be exposed to high noise levels for prolonged periods.
Introduction
The Marshall Dynamic Bass System was carefully designed using innovative new circuitry to provide you
with a combination of superb sensitivity and excellent control plus incredible levels of dynamic power to project
and respond to the full range of contemporary bass sounds.
Superb sensitivity comes from the fully blendable mixture of a valve or solid state input pre-amp. The solid-
state section offers fast, percussive attack, as favoured by many modern players, whilst the single ECC83 valve
provides the smooth warmth and more compressed classic tone exclusive only to valve technology.
Excellent control is derived from comprehensive EQ and compression facilities including primary EQ, where
Low and Hi rotary tone controls combine with deep and bright switches to give amazing depth and clarity to
your basic sound. More precise tone shaping or the ability to set up a completely contrasting sound, is available
from the switchable 7 band graphic EQ, which has been tailored to cut and boost those frequencies that are
fundamental to dynamic bass performance. The built in compressor provides further control and features
industry standard technology for smooth operation and the highest performance quality.
Knowing how important headroom and clean power are to accurate, powerful bass reproduction led our
designers to engineer a system with headroom that goes far beyond the normal limits. Whereas a conventional
bass amplifier has an RMS to peak power ratio of 1:2, the Marshall Dynamic Bass System dramatically
increases this ratio to 1:10, giving you five times more headroom than an ordinary bass amplifier.
The result is a no compromise bass system with an RMS rating of 200 watts capable of delivering peaks of
2000 watts. This ensures that the system has the energy to respond accurately to even the widest dynamic range.
In sound terms this extended headroom provides incredible clarity and punch to give you the most responsive,
rewarding bass amplification system that you've ever played through.
Using the Dynamic Bass System.
Make all the external connections such as Speaker Outputs (18), the Send (20) and Return (21) to
and from your effects processor, the output to your guitar tuner and connection to the footswitch for
the Graphic EQ (23) if required.
Select the correct input to match your bass.
