EFFECTS LOOP (Continued)
pass this junction. When the rotary control is swept toward
HIGH, the crossover will allow more of the upper harmonic
range to receive processing. Panned hard right (5:00), mostly
highs will be present in the loop's signal path.
CROSSOVER control set straight up (12:00), the whole range of frequencies
(lows and highs) pass equally through the EFFECTS LOOP. The MIX Control
lets you decide how much of the frequency specific affected signal you
wish to blend with the dry (unaffected) signal. Panned hard left, (0%)
removes all the wet signal from the mix. Panned hard right (100%) allows only
the wet signal to pass the MIX Control. In general, its always a good idea to set
up your signal processor with its mix control at 100% wet and then slowly raise
the M-2000 's FX LOOP MIX Control until you reach the desired blend. This scheme preserves the integrity of the attack and
punch characteristics the M-2000 is capable of delivering (when no processing is being used.) Finally, the FX LOOP AUTO
ASSIGN rotary control activates the loop as well as allowing you to engage it automatically in any of the three Modes when they
are called up with either the CHANNEL SELECT Rotary Control or the FOOT CONTROLLER.
NOTE A great way to check out the power of this advanced loop is to try this simple exercise:
processor to the SEND and RETURN (Input to SEND - Output to RETURN.) May we humbly suggest a "chorus" program as these
seem to be great for the purpose of this exercise.
CROSSOVER control to approximately 3:00 (this will allow mostly high frequencies to be processed.)
assign rotary to activate the loop in the Mode that you wish to play in.
LOOP MIX control until you reach the desired dry / wet blend.
Right away you should be able to appreciate the fact, that, while you have chorus (or whatever effect you choose) on "top" of your
sound, you have not lost the punch and authority that is so often sacrificed when using effects...especially less expensive units that
don't incorporate high quality operational amplifiers in their mixer and output stages. At this time you may also want to sweep the
CROSSOVER control over to 9:00 to experience the same test passing mostly low frequencies through the loop. While quite
different and interesting, we think most players will want to process their highs, keeping the bottom end tight with unprocessed
definition.
