With the LJ-12 Recorder, L.J. Scully offers the broadcast and recording industries a new standard in analog recording. Now audio engineers have complete Digital Control of an analog tape recorder. At the heart of the LJ-12 are three advanced micro-processors, each communicating with the other, allowing unprecedented operational stability and flexibility.
LJ-12 Recorder features:
■ Self diagnostics and plug-in circuitry for ease of service.
■ All connectors the finest available, including macliined-pin gold plated I.C. sockets and two-piece plug/receptacle type circuit card connectors.
■ Complete digital control of the transport functions including the use of lifetime hall-effect switching .
■ Solid-state, infra-red tape sensor using no moving parts or tape slots that interfere with tape threading.
■ Closed loop, dc servo capstan drive for ultimate speed accuracy Bi-directional servo capstan system allows reverse play capability.
■ The most accurate vari-speed system ever offered, with precise digital control of capstan speed from 3.00 to 36.00 IPS in .01 IPS increments, with L.E.D. display of IPS or percent of deviation.
■ Digital, real time position locator with LED display.
■ Home, replay and dump edit functions for ease of editing.
■ Shuttle control for easy cueing.
■ Digitally controlled constant tension reel motors for gentle tape handling.
■ Slow wind spooling mode for improved tape storage.
■ Long life, hot pressed glass bonded ferrite heads are standard.
■ Five position head stack allows spare head location in addition to the SMPTE time code head.
■ SMPTE compatibility using a center track between the two audio channels with a separate head to eliminate crosstalk problems.
■ Advanced, efficient switching power supplies insure cool operation without noisy fans.
■ Universal power supply mains input compatible with all world standards.
■ Versatile accessory connector allows access to all of the machine's vital internal signals including tallies, push-button inputs, and power supplies for easy interfacing to synchronizers and controllers.
■ Accepts both parallel and serial remotes and can be controlled using RS232 data (without the use of "black boxes").
■ Transformerless, high current, true differential output stage can supply +28 DBM and distortion-free unbalancing.
■ Quiet punch-in and out with bias delays precisely controlled by the audio control microprocessor.
■ Non-volatile memory stores all audio adjustment values and insures dependable storage without batteries.
■ Storage of separate values for every audio parameter, for all four tape speeds, for four tape types, with NAB or lEC standards.
■ Programmable fast-mute level and automatic high frequency correction prevents monitor speaker damage in lifter defeat mode.
■ Built-in monitor amplifier with headphone jack and terminals for console mounted speaker.
■ Quiet Operation
LJ-10 Reproducer features:
Engineered for performance and maintenance-free operation, the LJ-10 is built to exacting specifications by L.J. Scully craftsmen. This model offers unique advantages that have previously been unavailable to the broadcast industry. These features include:
■CIosed loop drive offering substantially improved wow and flutter.
■Linear actuated pressure rollers for a fast, smooth start.
■Built in foil sensing.
■Solid state logic control circuitry.
■Motion sensing for smooth control of fast and stop operations.
■Fault detection for early signaling of a potential malfunction.
■Front panel plug-in printed circuit construction for easy alignment and maintenance.
■Cue mode for easy loading and service.
