By grasping the switchbetween two fingers, shaking back and forth would changethe input from Phono to Line to Phono to Line, etc. Thiswould result in a stuttering type effect. The problem with it isthat the Phono/Line switches often break and repairing themis costly.B. TRANSFORM SWITCHES: Your mixer is equipped withtwo removable Transforming Switches. These switches turntheir channel from off to on to off, etc. This results in thesame type stuttering effect. The TRANSFORM SWITCHES(22,23) have been positioned, by the factory, to move fromside to side. By unscrewing the 4 screws from theTRANSFORM SWITCH (22,23) plate, you can turn theswitch in 90 degree implements. This allows up/down,down/up, right/left or left/right positioning. TRANSFORMSWITCH (22) controls channel 1. TRANSFORM SWITCH(23) controls channel 2.C: PROCEDURE: Set both CHANNEL LEVEL SLIDE (8,9)to your required levels. With the CROSSFADER (13) to theright (channel 2), moving TRANSFORM SWITCH (23) fromwhite to orange to white will result in a stuttering effect. Withthe CROSSFADER (13) to the left, moving TRANSFORMSWITCH (22) will give the same results. You can vary theeffect by flipping the switch faster or slower, longer orshorter..D. ADDITIONAL EFFECTS: Set both CHANNEL LEVELSLIDE (8,9) to your required levels. Place TRANSFORMSWITCH (22) in the orange position. Slide theCROSSFADER (13) from the right to a positionapproximately 1/3 of the way towards the left. (Channel 2should still be playing through the speakers.).
