Introduction
The Marshall JFX-1 is a totally programmable 24 bit digital effects processor which features the
highest quality effects algorithms and also allows complete control via MIDI.
By utilising a 64x over-sampling 16 bit Sigma/Delta Analogue to Digital converter in conjunction
with 16 bit linear dual Digital to Analogue conversion, the JFX-1 produces effects that have superb
resolution and depth, with an absolute minimum of distortion and maximum dynamic range.
Also by incorporating a high quality Voltage Control Amplifier the all important dry signal is kept free
from degradation - essential for maintaining the integrity of your direct sound.
Although suitable for all processing applications the JFX-1 has been designed primarily as a guitar
rack effects processor. The first 50 programs have been pre-set at the Marshall factory but may be edited
in full. They can also be restored without loss of data custom programmed into memories 50 to 127. The
individual algorithms for Chorus/Flange, Multi-Tap Delay, Delay, Reverb and Multi-Effect, give you the
ability to edit and store a superb library of effects, with no unnecessary or redundant features to confuse
the issue.
If you want to use the JFX-1 with an amp head or combo which has channel switching facilities the
special Remote Jack can be programmed to activate the Channel switch as part of the selected program.
Whether you are recording in a professional or home studio or playing live through a combo or full
stereo rack system, the JFX-1 puts a vast range of creative possibilities instantly at your fingertips.
It is advisable to keep this manual in a safe place for future reference after studying it carefully, as
gaining a full understanding of how the JFX-1 operates will ensure that you are getting the most from it’s
processing power- especially when designing your own personal sounds.
