Vinyl records are thin and flexible and often warped or bowed. As most records do not lie flat on the turntable platter, sound reproduction suffers due to un-dampened vinyl resonance caused by the stylus riding on an unsupported record, or the air moved during listening with speakers. Records which are bowed downward contact the platter at the outer edge but not in the middle. Conversely, records that are warped or bowed upwards tend to rock on the platter. In these instances Anti skating compensation is less effective and record wear is increased substantially by the lateral or vertical seesawing motion of the tonearm/cartridge combination. The Acoustic-Signature GRIP Record Clamp solves these problems by bringing the record into more intimate contact with the platter. To use it, place the record on the patter and place the clamp on the record. Press and turn the upper knob clockwise to lock the unit. The record clamp's peripheral edge will force down the outside of the record label area thereby causing the record to completely contact the platter surface. To remove the clamp, it is only necessary to turn the knob 1/4 turn counter clockwise. The knob does not have to be unscrewed completely. Like all other Acoustic- Signature products the Grip is made on high precision CNC-machines to make sure perfect quality and minimal tolerances. 

Load Record Weight Stabilizer ( available in black or silver ) The Acoustic Signature Load record weight stabi­lizer elimi­nates the sound degra­dation caused by wavy records. The stabi­lizer distri­bu­tes its pres­sure evenly across the record and, by impro­ving the platter con­tact, mini­mizes unwan­ted vibra­tion thus provi­ding a smoo­ther cart­ridge tracking.
