Cardas Audio Frequency Sweep and Burn-In Record Mk II LP
Stereophile Magazine Recommended Component
Leave it to George Cardas to keep your turntable-based system at peak performance with a cutting-edge tool for system set-up, diagnostics, and maintenance. Produced by George Cardas and mastered by Stan Ricker, the Cardas Frequency Sweep and Burn-in Record includes all the essential standard tones plus relative and absolute polarity checks along with vocal channel identification.
To combat accumulated magnetic grunge, George provides a trio of frequency sweep tracks that ultrasonically clean the cartridge stylus and degauss the entire system. Also on-board are locked pink noise grooves that repeat endlessly, blank plateaus, and even a sync label to check platter speed. "The Sweeper" is mastered at 16 2/3 rpm, plays at 33 1/3 rpm and comes in a super-stable 180 gram pressing.
