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).
