Yamaha CDR-HD1300 CD/Hard-Disk Recorder

IN THE LAB
CD DIGITAL DUBBING AND DIGITAL-INPUT RECORDING
Bit-accurate at CD-standard 44.1-kHz sampling rate. CD ANALOG-INPUT/OUTPUT RECORDING
All analog-input measurements were made from the hard-disk drive, through the analog output. For all measurements except input sensitivity, the record level was set to a point that produced a 0-dB reading with a 2-volt input. This produced a -20-dBFS recording from a 200-millivolt input, the reference level for the noise measurement. Input sensitivity (to produce a 0-dBFS recorded level, record-level control up full) : 425 mV Distortion (THD+N, 1 kHz)
at 0 dBFS: 0.0046%
at -20 dBFS: 0.036% Linearity error (at -90 dBFS): +0.4 dB Noise level (A-wtd): -72.0 dB Noise modulation: <0.25 dB Frequency response
20 Hz to 20 kHz +0, -0.42 dB CD AUDIO PERFORMANCE All tests except defect tracking were made with Sound & Vision's test CD-RW, whose signals contain dither, which sets limits on measured distortion and noise-level performance. Maximum output: 2.2 volts Frequency response
20 Hz to 20 kHz +0, -0.15 dB Excess noise (without/with sine tone)
16-bit (EN16): +0.45/+0.45 dB
quasi-20-bit (EN20): +7.1/+7.1 dB
at 0 dBFS: 0.0025%
at -20 dBFS: 0.019% Linearity error (at -90 dBFS): +0.2 dB Noise modulation: <0.25 dB Defect tracking
(Pierre Verany test disc): 4,000 µm The Yamaha CDR-HD1300 was exemplary on the test bench. CD playback provided essentially flat frequency response, very low noise and distortion, negligible linearity error, and superb excess-noise figures. On top of that, it successfully tracked the largest defect on the test disc. Analog input/output from the hard-disk drive was similarly good, with remarkably flat response and low distortion and noise considering the signal's trip through both analog-to-digital and digital-to-analog converters. - K.P.
