Marshall electronic AUDIOSTATE LR150 - Manual (Page 4)

ENGLISH
3
compression driven Constant Directivity high frequency horn with a pro grade
crossover and horn protection circuit. Each channel has 3 band EQ, gain and FX send
controls, whilst the master has a parallel FX loop, spring reverb and line outs to send
the mixed signal to a larger PA system or tape recorder if required.
The LR300 features a protection device fitted to the cross over filter to protect the
horn. If pushed too hard into distortion, the horn will be automatically de-activated.
Once the protection device has cooled down sufficiently it will re-activate the horn.
Besides the rugged side carrying handles, the LR300 has built in castor inserts to suit
the optional Marshall castors, available from your Marshall dealer.
LR230
The Marshall LR230 is a stereo 30 Watt 2x10” combo and is ideal for home practice
use providing the user(s) with the opportunity to mix up to 2 stereo sources such as
keyboards, drum machines, tape decks, CD players and sequencers. Other features
include an internal limiter to prevent distortion, a parallel effects loop and an in-built
spring reverb.
LR150
The Marshall LR150 however is ideal for rehearsals and gigging. This 1x15” with
piezo horn combo provides 150 Watts of power and allows a mix of up to 4 different
inputs. The user(s) can send the mixed signal via the Line Out to a P.A. which is
independent of the combo’s master volume allowing the combo to be used as an
onstage monitor. Other features include an internal limiter to prevent distortion, a
parallel effects loop and an in-built spring reverb.
This handbook is designed to help you get the most from your Marshall Linear
Response amplifier. We would suggest that you read this carefully before plugging in.

device used.
3. Left / Mono Jack
This is for either a mono input or the left side of a
stereo input if item 4 is used as well. This is a
high impedance unbalanced input. Typical uses
