| Equipment Used: | Test media was a custom CD created with CoolEdit Pro 1.1 in 32 bit mode, converted to 16 bit with 0.53 bits of spectrally uniform, Gaussian distributed dither; and burned onto Ricoh media using a Plexstor R412C and EZ CD Deluxe 3.5. Signals processed into computer using an Event Layla. Signal analysis with SpectraLab 3.32.14. | |||

Discussion Of Results
This CD player has SP/DIF (RCA), balanced analog (+4, XLR), and unbalanced analog (-10, RCA) outputs. The XLR analog outputs were tested. Reference level (digital Full Scale) voltage from the balanced output is approximately 12.5 volts, which may cause input clipping with some equipment. There is no output level control to regulate this.
