The Sony PCM-2300 was the professional version of the DTC-57ES
Improvements over the consumer DTC-57ES included:
- Better designed boards
- XLR Inputs and Output connectors
- Defeatable SCMS
(1) Digital Audio Recorder Compatible With DAT Format Standard
Audio signals are converted into 16-bit quantized digital data for recording and playback realizing pure reproduction with virtually no degradation in sound quality. Moreover, the basic tape format is compatible with consumer-use DAT equipment.
(2) Professional-use Digital I/O
Digital I/O terminals (unbalanced phono jacks) conform to the professional format standard (IEC95 8-TYPE I*) enabling digital dubbing using another PCM-2300. The digital input terminals also accept consumer format (IEC958-TYPE II*) signals for digital recording from consumer-use equipment.
(3) Wide-range Analog I/O Level Adjustment
Rear panel signal level adjustment function for the balanced type (XLR) analog I/O jacks covers a wide adjustment range from professional-use to consumer-use levels.
(4) 2-Head, 2-DD Mechanism
The PCM-2300 employs usual two-head (Recording/playback) system. Moreover, two motors for drum and capstan offer direct-drive operation for improved tape transport stability.
(5) Compatible With Various Sampling Frequencies
Allows recording and playback in both standard play (SP) mode and long play (LP) mode compatible with consumer use equipment. Analog recording is possible at sampling frequencies of 48 kHz (SP), 44.1 kHz (SP) and 32 kHz (LP), and digital recording is possible at sampling frequencies of 48 kHz (SP), 44.1 kHz (SP) and 32 kHz (SP/LP). Playback is possible at all frequencies and modes.
(6) Remote Control Operation
Wireless/wired remote control is possible using the supplied RM-D2300 remote commander.
(7) Various Subcodes and Search Functions
In addition to the Start ID, Skip ID and End ID, other subcodes such as the absolute time and program number can be recorded in and read from the tape's subcode area to provide a wide variety of convenient DAT search functions.
(8) Built-in Date Function
A dedicated built-in clock is used to automatically record the date (year/month/day), day of the week, and time (hour/minute/ second) in the tape's subcode area, allowing confirmation of the date and time of recording during playback.
(9) Multi Display Provides Quick Access to Many Types of Information
In addition to displaying the program number and various types of time/counter data, this display is provided with features including a 21-segment peak level meter and a 0.5 dB-step peak margin indicator.
(10) Rack Mounting Compatibility
Use of the supplied adapter allows mounting in a standard 19" rack.
