The record size is automatically set by a photo sensor system. If no

record is on the turntable, the tonearm will not descend but will

automatically return to the arm rest. A muting system activates

when the tonearm is lifted and deactivates after the tonearm

lowers onto a record so there is no need to turn the amplifier

volume down every time a stylus is placed on a record.
