OVERVIEW For ease of understanding the M-2000 and to reduce the intimidation factor that one might experience upon first glance, it should be noted that the unit may be digested one channel at a time. The only shared controls on the entire front panel are the MIX control and the Output Level control. Thinking of the M-2000 as two completely separat[...]

FRONT VIEW BASIS M-2000 By now you see the M-2000 houses two completely different pre-amplifiers, one all tube, one FET. These may be footswitched between and/or combined by utilizing the Mix Mode, in which any blend of the two may be created. The Tube Channel offers the choice of a normal (low gain) mode operation and an all tube Hi Gain overdrive[...]

Set the FIELD EFFECT CHANNEL rotary controls and the 9 Band Graphic E.Q. per this example, making sure that the FET channel's MASTER control is set to zero. You will notice there is no Gain control in this channel. This was done to make room for a different tone control wiring scheme. The FET channel's Treble and Mid are wired in the same[...]

PAGE 5 In this channel the bass frequencies are shaped utilizing a pair of parametric type controls. Two rotary controls, Bass and Bass Frequency enable you to center in on the region of lows that you wish to enhance and boost or cut them to your desire. Just to the right of these two controls there is a mini-toggle switch that enables you to "[...]

While still in the MIX Mode, select the HI-GAIN setting of the MIX ASSIGN Switch in the TUBE Channel's lower left corner. Start wi[...]

BALANCED OUTPUT / BALANCED LEVEL (Continued) Balanced Output XLR jack. Basically, this means that your instrument is going directly into the console with no alteration from the M-2000 . Sometimes this is preferred when playing venues with large sound systems that have plenty of low frequency power of their own and don't always need the added s[...]

EFFECTS LOOP (Continued) When panned hard left (7:00), mostly lows will 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. With the CROSSOVER control set straight up ([...]

PAGE 12 NOTE If you wish to use the External Select Jacks to call up a Mode or E.Q., you must have the Rotary Mode Select Switch (located on the right side of the Rear Panel) set to the EXT position. These External Select Jacks can always be used to select a Mode, regardless of the state of any other switching logic. EPILOGUE We hope this manual ha[...]
