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-2000is 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: 1. Connect your favorite signal 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. 2. Set the signal processor's Dry / Wet Blend to 100% Wet. 3. Sweep the CROSSOVER control to approximately 3:00 (this will allow mostly high frequencies to be processed.) 4. Use the FX LOOP AUTO assign rotary to activate the loop in the Mode that you wish to play in. 5. While playing an open string, slowly increase the FX 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.

SPEAKER OUT	The BASIS M-2000provides two types of
	interconnects for powering speaker enclosures,

XLR and the standard 1/4 inch phono jacks. Each of these formats include a pair of jacks that are wired in parallel and which may be used individually or together to power additional cabinets. The recommended speaker load impedance for the M-2000is 4 Ohms at which the mighty SIMUL- STATE power section is capable of delivering a whopping 625 watts RMS before clip, and peaks of over 2000 watts! A speaker load of 8 Ohms may also be used and at this impedance, though the overall power will be reduced to roughly 300 watts.
