TROUBLE SHOOTING:
BELT NOISE:
While a small amount of belt noise is normal, excessive ticking, scraping or squeaking can be eliminated by
applying a small amount of WD-40 lubricant to the V-Belt itself. The belt tension should also be checked. There should be about 1/2"
of play...(slightly looser than the fan belt on a car engine.)
BRAKE NOISE:
A quiet, even rubbing sound is normal when the brake is engaged. If this sound appears to be excessively
loud, the angle at which the brake shoe comes in contact with the motor casing can be adjusted. The shoe should drag against the
casing and not "stub" into it.
If the Brake makes a loud thumping sound when it first engages, the distance between the Brake shoe and the motor casing is too
great. This distance should be no more than 1/32" and can be adjusted via the bracket that the Brake shoe itself is fastened to. This
adjustment may need to be made after 1 to 2 years of use.
STUCK IN FAST:
the 3 position toggle switch on the Front Panel is in the low or down position. If both of these controls are set properly and the problem
persists, then it is likely that the small DC motor which controls the slow speed has failed or that the belt which runs this motor from the
main shaft has broken.
CASTORS:
IMPORTANT ! The weight of the internal speaker cabinet is such that when it is in motion it is unsafe to leave the
castors on the REVOLVER. Always Remove Castors Before Using. Also...make sure that each corner of the REVOLVER'S
bottom is firmly seated on the floor to avoid excessive shimmying.
MIKING TECHNIQUES:
right on opposite sides of the REVOLVER at a distance of 1 to 3 inches. Lowering the mikes closer to the center of the grille will
result in a deeper effect with a greater amount of wind noise. Raising the mikes up to the top of the grille area will lighten the effect and
eliminate wind noise. When using this placement scheme, it may be desirable to angle mikes downward slightly.
NOTE: The REVOLVER has many moving parts. While we have eliminated almost all excess noise, some minor mechanical
sounds are unavoidable. Remember...there are no user serviceable parts inside and refer all servicing to a qualified technician.

Make sure the Slow Speed Fine Controller is not turned up too high. When using the footswitch make sure
For stereo miking, the best results seem to be attained by using two microphones panned left and
