Ground lift Operation

Due to the variety of power sources available to the DJ, Stanton has included a ground lift switch to be used on the ST- 150/STR8-150 turntables. This will allow the DJ to have the capability of changing the grounding scheme of the phono cartridge to avoid ground hum that may occur when using the turntable. The ST- 150/STR8-150 Turntable has been designed to operate with third pin safety ground, and should always be used when available. N E V E R R E M O V E T H I R D P I N G R O U N D F R O M THE POWER CORD PROVIDED, IF NECESSARY, USE THE APPROPRIATE ADAPTER FOR PLUGGING INTO OUTLETS WHICH DO NOT PROVIDE THIRD PIN GROUND TERMINALS.

For best operation of the ground lift, the following rules should be applied

When third pin safety ground is used, set the ground lift switch to the lift position. This position will isolate the cartridge ground from connection to earth ground.

When third pin safety ground is unavailable, set the ground lift switch to the connected position. This will place the cartridge ground in connection with the chassis ground, but since third pin grounding is not used, the cartridge ground will not be in connection with earth.
