Model: ES57 Release Date: 1992-03-20 Creation Date: 2024-12-09 22:08:43 Description SCMS-compatible DAT deck equipped with a latest-generation pulse-type D/A converter and numerous advanced functions. Equipped with SCMS (Serial Copy Management System), it allows digital-to-digital recording from a CD player (limited to one generation). An SCMS-compatible DAT deck can digitally record from a CD as the master source, but it cannot create a second digital copy from an already digitally recorded tape. A tape recorded via analog input allows one digital generation copy, but not a second digital generation. In the case of satellite broadcasting, it is also possible to produce second-generation digital tapes from digital audio sources. In all cases, recording can always be repeated using analog input/output connections. Mechanical System Features a 2D mechanism with dedicated motors: Direct-drive capstan motor Direct-drive head drum motor Dedicated reel motors Uses a vertical transparent cassette compartment. A/D and D/A Conversion The A/D converter is a 1-bit type, capable of shifting unwanted noise generated during A/D conversion far beyond the audible band. This allows the use of a gentler low-pass filter, minimizing phase distortion and group delay degradation. The D/A converter is also a 1-bit pulse type. It uses a single electronic switch to turn a current source on/off at high speed (approx. 500,000 times per second), representing musical signals as dense pulse waveforms. In principle: No crossover distortion No differential non-linearity distortion Natural, high-quality sound reproduction Servo and Signal Processing Uses a software-based servo system, meaning motor control is handled by software. This enables: Smooth progressive search Speeds up to approximately 200× Reduced tape wear Improved cue/review sound quality Incorporates a second-generation LSI integrating: Error correction RAM control Digital I/O Integration density: 20,000 gates per LSI. The microcontroller for servo and mechanism control is also integrated into a single LSI, reducing components and improving reliability. DAT Subcode Functions Advanced DAT-exclusive subcode features include: Start ID Auto mode (automatic writing at track start) Manual mode Erase capability Skip ID Automatically skips marked sections during playback End ID Marks logical end of tape Includes a rehearsal mode for writing Start/Skip/End IDs during playback, with fine adjustment in 0.3-second increments. Additional functions: Program number assignment Direct selection via numeric keypad Automatic renumbering Program shift function Absolute time recording Built-in clock for automatic date/time subcode recording Playback and Search Functions AMS playback (skip to previous/next track) Direct program number search Music scan (approx. 8 seconds per track) Single track or full tape repeat End search (locates final ID or unrecorded section) The included remote control allows programming up to 99 tracks in any desired order. Extended Recording and Editing LP mode enables continuous recording up to 4 hours (using DT-120 tape). Fade-in/fade-out is available for analog recording input and digital/line output playback. Fade time adjustable from 0.2 seconds to 15 seconds. Useful for editing and master transfers. Connectivity Coaxial digital input/output Optical digital input (switchable from front panel) Digital signal normalizing servo-type circuit on optical input Digital peak margin display in dB Includes FS Map function, visually indicating sampling frequency: Upper meter illuminated: 32 kHz Lower meter illuminated: 48 kHz Both illuminated: 44.1 kHz Remote Control Supplied with a wireless remote control capable of: Operating most deck functions Controlling compatible CD players CD-synchronized recording Variations Available in two finishes: Gold Black The remote control color matched each finish version.
