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
