S.C. Code § 17-23-140
Upon the defendant's signing the waiver of presentment and the plea of guilty the clerk of court shall deliver the indictment to the sheriff or one of his duly authorized deputies whose duty it shall be to appear before the resident judge of the circuit or presiding judge therein at some convenient time and place, having with him the defendant. And upon the defendant's acknowledging his plea before the judge the judge shall sentence the defendant as though the indictment had been presented by the grand jury and the plea of the defendant taken at the regular term of the court of general sessions of the county in which the case arose. Provided, however, that in the event the defendant is charged with a felony, the acknowledgement by the defendant of his plea and the sentencing by the judge shall take place only in open court and shall not take place in chambers.
