The Cardas Frequency Sweep and Burn-in Record is a unique tuning tool for system set-up, diagnostics and maintenance. It was produced by George Cardas and mastered by Stan Ricker. In addition to the standard tones, this LP includes relative and absolute polarity checks, vocal channel identification and frequency sweeps that ultrasonically clean the cartridge stylus and degauss the entire system. And, locked, pink noise grooves that repeat endlessly, blank plateaus, even a sync label to check platter speed.
All on a 180 gram pressing with a smiling Stan cover.
( Sweeper • 45 rpm (also works @ 33 1/3rd rpm). Note: This is three cuts, interleaved with smooth sections, to be played at 45 rpm.)
- Track 1. Short Sweeps, short version (52 seconds)
- Track 2. Short Sweeps, long version (4 minutes 46 seconds)
- Track 3. “I’ve Got a Feeling I’m Falling” Artists: Tom Loncaric Band. Music Thomas Waller and Harry Link. Publisher: Ann Rachel Music. (2 minutes 29 seconds)
- Track 4. 1K tone (740.46Hz tone @ 33 1/3rd rpm)
( Burn-In • 33 1/3 rpm. Note: Burn-in is mastered at two different speeds and designed to be played at 33 1/3 rpm. The first section, from the outside edge to the lock-out groove (the stylus will stay in the groove until lifted out), is mastered at 16 2/3 rpm. Tracks 2, 3 and 4 are mastered at 22 1/2 rpm)
- Track 1a. Voice announcement by George Cardas, "Greetings from the left channel"
- Track 1b. Voice announcement by George Cardas, "From the right channel"
- Track 1c. Voice announcement by George Cardas, "From both channels" Note: This is lateral modulation (mono, in phase).
- Track 1d. "In polarity" Both channels in positive polarity
- Track 1e. "Out of polarity" Both channels in reversed or negative polarity Spiral
- Track 1f. 13 strikes on a high "B-flat" on a piano Note: The last of the 3 strings are brought into zero-beat, dead-on tuning. Listen for the impact of hammer on string, quickly followed by room reflections mingling with one another, followed by a keener sense of the piano sound itself, as the ring-out time of the string exceeds that of the reverb time of the room.
- Track 1g. Hollow sticks, of various lengths and diameters, being struck, one on another. Note: It is recorded in a very reverberant, spacious environment. The spatial, impact and directional cues will not sound correct if the polarity is wrong.
- Track 2. 20 locked grooves, lateral modulation (mono)
- Track 3. 32 locked grooves, vertical modulation (out-of phase)
- Track 4. 20 locked grooves, lateral modulation (mono)
- Track 5. 26 unmodulated grooves Note: These unmodulated grooves facilitate electro-forming (matrix) operations and help vinyl flow in the record press, for a quieter, flatter disk.
