Confidence Monitoring
Designed with a 4- head rotary system , the PCM-7030
recorder provides two recording modes, RAW (Read-After-Write) and RMW
(Read-Modify-Write). In RAW mode, real-time off tape monitoring is
provided. In the RMW mode, the PCM-7030 allows enhanced punch in and punch out operation with crossfading at the punch in and out points.
Comprehensive Serial Remote Control
The PCM-7030
is equipped with a 9-pin serial remote connector for convenient control
from external equipment. This includes Sony video controllers such as
BVE-2000, BVE-9100 and RM-450 for audio-follow-video applications. For
computer control automation applications, the PCM-7030 also features an RS-232C connector.
Variable Speed Playback
The precision-controlled transport of the PCM-7030 allows the playback speed to be varied over a range of ±12.5%.
Variable Speed Recording
Varispeed recording is also possible allowing " pull up" and " pull
down" ±1% recording sample rates (for example, 48.048kHz or 47.952kHz).
Pull up or pull down recordings permit automatic ±0.01% speed change
during playback for film/video post production when necessary.
Memory Start Function
Approximately 3 seconds of audio data from around the play starting
point is stored in a stereo digital sound memory and this memorized
sound is output instantly when the play key is pressed. This eliminates
the problem of the output sound being delayed, which is inherent in a
rotary head system and makes the PCM-7030
suitable for on-air applications and audio post production. The start
point can be trimmed and the designated start point can be rehearsed any
number of times. When operating the time code locate or start ID locate
function in memory start mode, the PCM-7030 automatically stores that audio data around the locate point for instant playback.
