Introduction
LR300
The Marshall LR300 is a combination of a 5 channel mono mixer, high quality 300
Watt RMS power amp with distortion reducing limiting circuit and a compact high
quality loudspeaker system, intended to provide a very versatile single unit solution
to all applications where linear stage amplification is required. Let us just take a
moment to understand what we mean by Linear Response. Linear response
essentially means getting out what we put in, only louder, without any undue
colouration, distortion, or undesired frequency changes, just as you would expect
from a good PA or HiFi system. Those qualities are desired in a guitar amp, for
instance, but NOT when you are amplifying keyboards, sound modules, pre-recorded
music or vocals. The LR300 allows you to do this with ease as it is self contained in
one package, rather than carrying around (and finding stage space for) the minimum
of three units that would make up a normal PA type set up.
The LR300’s 5 channels come equipped with a variety of input and sound forming
options, plus the power and sonic quality to enable many different live sound uses to
be performed. For instance, the LR300 can be used to mix and amplify up to 5
keyboards, sound modules and/or sequencers, as either a main system at club level
or as a monitor system on louder concert stages. Want to use a guitar as well? No
problem! With the inclusion of the reknowned Marshall loudspeaker emulation
system on channel 4, not only is great clean guitar sound possible, it also allows the
use of external distortion generating effects, i.e. stomp boxes or preamps, without the
sound being harsh and fizzy, unlike a normal PA system or mixer. Great for keyboard
players who double on guitar!
Besides the normal jack line inputs on all channels, channels 1 and 2 also feature
balanced XLR inputs for low impedance microphones for vocal or acoustic instrument
amplifying duties, plus channel 5 also has phono inputs for tape, CD, or even a
computer sound card! Channel 1 also features a dedicated series FX loop, so that you
can add specialised FX to that channel, i.e. how about a harmonizer on your vocals?
With so much versatility on tap the creative horizons of the LR300 are quite
boundless. For example, how about using it as a percussion monitor - miking and
mixing both electronic and acoustic drum sources. Or as a “band in a box” used by
solo/duo artists (or even a full band!) for bar, lounge and cabaret functions where
space and transport is limited, but high quality sound is the order of the day. For the
more technically minded the LR300 also features a 15” premium bass driver and
