HIGH RESOLUTION CONVERTERS DELIVER SUPERB SOUND QUALITY

THE AUDIO PERFORMANCE OF ANY DIGITAL TAPE RECORDER IS ALMOST ENTIRELY DEPENDENT ON THE QUALITY OF THE A/D AND D/A CONVERSION AT ITS INPUTS AND OUTPUTS. IT IS IN THESE CONVERTERS THAT THE SIGNAL IS MOST LIKELY TO BE DEGRADED. SONY HAS FITTED THE PCM-R300 WITH 20-BIT DELTA-SIGMA A/D AND 1-BIT PULSE D/A CONVERTER TECHNOLOGY TO ENSURE STABLE, HIGHLY LINEAR PERFORMANCE WITH EXCELLENT SIGNAL-TO-NOISE RATIO.

SBM PROVIDES 20-BIT SIGNAL QUALITY FROM 16 BITS

THE DAT FORMAT USES 16-BIT FORMAT RECORDING. THE SIGNAL FROM THE ANALOGUE TO DIGITAL CONVERTERS IS PROCESSED BY THE UNIQUE SONY SBM (SUPER BIT MAPPING) CIRCUITRY THAT USES ADVANCED NOISE SHAPING TECHNIQUES TO ACHIEVE A DYNAMIC RANGE OF A 20-BIT SIGNAL WITH ONLY 16 BITS. THIS ADVANTAGE IS PRESERVED DIGITALLY, SO A DAT RECORDING MADE ON AN SBM-EQUIPPED MACHINE PRODUCES A CLEARER SOUND ON A SUBSEQUENT CD MASTER.

ALL THREE SAMPLING RATES SUPPORTED, INCLUDING LONG PLAY

IN NORMAL PLAYBACK MODE THE PCM-R300 SUPPORTS SAMPLING RATES OF 44.1 KHZ AND 48 KHZ, SELECTABLE FROM THE FRONT PANEL. THE 32 KHZ LONG-PLAY FORMAT ALLOWS UP TO FOUR HOURS RECORDING TO BE MADE ON A STANDARD TWO-HOUR DAT CASSETTE. THE SIGNAL IS SAMPLED USING 12-BIT, NON-LINEAR QUANTISATION.

ADVANCED ERROR CORRECTION

THE DOUBLE-ENCODED REED-SOLOMON ERROR CORRECTION CIRCUITRY IS ABLE TO CORRECT OR CONCEAL MANY OF THE ERRORS CAUSED BY DAMAGED TAPES OR POORLY RECORDED MATERIAL FROM OTHER MACHINES. THE PCM-R300 FEATURES AN ERROR-RATE DISPLAY THAT MAKES IT EASY TO SEE WHEN HEAD CLEANING IS DUE OR IF A POOR QUALITY TAPE IS BEING USED.

ID CONTROL

ALL THE CONTROLS NECESSARY TO RECORD START ID, STOP ID AND SKIP ID ARE AVAILABLE ON THE PANEL. THEY ARE DUPLICATED ON THE STANDARD, INFRA-RED RM-D757 REMOTE CONTROL UNIT.

RELIABLE MECHANISM

THE FRONT LOADING MECHANISM OF THE PCM-R300 USES A 2 HEAD DUAL MOTOR DESIGN WITH AN ADVANCED SERVO CONTROL SYSTEM FOR HIGH RELIABILITY AND PRECISE TAPE HANDLING.
