User manual MARSHALL JMP-1

[. . . ] JMP-1 HANDBOOK ENGLISH From The Chairman I would like to thank you personally for selecting the JMP-1 MIDI Pre-amp. As our first venture into MIDI controlled guitar equipment, many hours of development have been spent ensuring that it fulfils the functions that you really need to cope with todays widely varied playing environments. We have always worked very closely with guitarists from many different fields and their valuable input has been an essential ingredient in the creation of the JMP-1. My design team is made up of guitar players who fully understand the needs and realities of guitar performance. [. . . ] If using a mono effects processor the left hand return socket only should be used. In this instance both the left and right master outputs and speaker emulated outputs will now be working in mono. Provides level selection of +4dB or -10dB to match the level of external effects processors. Connection point for optional Marshall four way footswitch to give 4 patch selection. Sends out MIDI messages identical to those coming in through the MIDI IN terminal. Your JMP-1 is provided with a detachable mains (power) lead which is connected here. Before connecting for the first time, please ensure that your JMP-1 is compatible with your electricity supply. MAINS INPUT When you switch on When switching on the JMP-1, the unit will run through an initialising process and will then default to the patch number that was selected when the JMP-1 was last switched off (Fig1). Your JMP-1 is now ready for action. Fig 1 Patch Patch Data Patch Store Creating Your Sounds Your JMP-1 is capable of producing a vast array of different tones, stored in the 100 available patches. The simplicity of creating and storing these sounds is a major advantage and feature of the pre-amp. A "Patch" is a combination of all the programmable elements that you put in, therefore if all tone and volume selections are at 0, no sound will be produced. OD1, OD2, Clean 1, Clean 2 & Bass Shift (B) The individual volume, gain, tone and effects levels that you have selected. The first step is to select a patch by pressing the patch key (5) using the rotary data control (7) to reach the desired patch number. The next stage is to "build" your required sound, firstly by selecting the channel OD1, OD2, Clean 1 or Clean 2 with or without bass shift, then by selecting the volume, gain, tone and effects levels. These controls work in exactly the same way as a normal Marshall amplifier, where increasing the gain brings in more overdrive and the tone selections interact to "shape" the sound. As the gain is increased you pass through degrees of distortion into a rich higher gain mode, with just the right nuances for the modern blues rock player. Vintage crunch, modern metal and fat blues lead sounds are all readily available. OD2 Tightly focused stunning high gain is what you will find in OD2. Modern and aggressive, smooth and fluid, the gain levels and singing tone of this channel will give you infinite sustain whilst retaining a pure toneful quality. Bass Shift The Bass Shift option can be switched in or out of any channel selection. When selected it thickens the bottom end of the sound and tightens the playing feel. On clean selections it adds body and on overdrive provides the extra low end "throb" so essential for heavy rock sounds. 6 Factory Sounds ENGLISH Your JMP-1 has 26 sounds ready programmed into patches 00-25. These sounds can all be edited in the way described earlier and recalled if necessary using the procedure described in the section-"to re-initialise the JMP-1.

Outgoing MIDI program Patch Data Patch Store Store Store Indicates 100-127 10 Four Way Footswitch ENGLISH The optional Marshall four way footswitch (model MPM 4E) provides a simple means of selecting four patches. The footswitch will call up patches one to four, however, the Mapping facility can be used to call up any four of the 100 JMP-1 patches. To Re-initialise The JMP-1 This procedure will re-load the factory sounds and reset the mapping table. WARNING:- Your edited sounds will be lost if the unit is re-initialised. Procedure, Hold down OD1 and Clean 1 whilst switching on the power. Memory back-up The JMP-1 has an internal battery back-up system to keep your patches safe while the unit is switched off. If any errors are detected an "E" will be displayed momentarily (Fig 8). [. . . ]
