DRP-1 Direct Recording
Pre-amp.
The Marshall Direct Recording Pre-Amp
is in essence a complete Marshall stack in
miniature, despite it’s compact size the
DRP-1 uses micro electronic techniques to
emulate the tone and feel of a typical
Marshall pre-amp, power amp and
loudspeaker cabinet. This allows the
recording and reproducing of great guitar
sounds with the minimum of fuss and
without the need to set-up and mic your
normal guitar amp rig.
The benefits of the DRP-1 can be utilised
beyond the realms of the home studio.
For instance the built-in stereo headphone
amplifier can be coupled to your favourite
effects processor to give your personal
practice routines the realism of your stage
sound. Alternatively, use the DRP-1 plugged
into the front end of your normal guitar amp
to fully ‘Marshallize’ it.
Another use of the DRP-1 is to go direct
into the PA from the emulated line-out. This
is especially handy for rehearsal, where
instead of transporting your main system
along, you can turn up with the DRP-1 and
just plug in and play.
In addition to the guitar uses, the Direct
Recording Pre-Amp can be used to add
warmth and another dimension to keyboards,
especially when mixed with the original
sound.
Front Panel.
1. Pre-Amp Volume.
Controls the level of input gain. Lower levels
will produce cleaner sounds, whilst higher settings
will increase the distortion produced by the pre-
amp circuitry.
The boost switch (Item 7) provides two basic
gain levels comparable to classic and
contemporary Marshall amps.
2. Master Volume.
As in a true guitar amplifier the master
volume regulates the amount of signal passed
from the ‘pre-amp’ into the ‘power amp’ section.
The amount of drive passed through to the
power amp will influence the tone and overdrive
capabilities of the entire unit.
3,4 & 5. Bass, Middle & Treble
controls.
The Middle and Treble controls are based on
the passive system found on most Marshall amps,
but have a wider sweep allowing you to re-create
many types of guitar amp sounds.
The active Bass control is designed not only
to interact with the Treble and Middle controls,
but also to emulate the resonant low end ‘Thump’
associated with a Marshall 4x12 cabinet.
6. Line Level.
Controls the output level from the Pre-Amp
Out jack (Pre Speaker Emulation), from the
Speaker Emulated Line Out jack and from the
Headphone Amp.
7. Boost/ Battery level switch.
Multi purpose switch that selects the two gain
parameters of the pre-amp and also a ‘momentary’
position to test the battery level in conjunction
with LED (Item 8).
