NEC DAT deck.

A dual mechanical chassis with a double structure is adopted for the rotating head part, and on top of that, a special floating mechanism is adopted to prevent deformation pressure from the outside, and it demonstrates trace capability with high precision and excellent stability.

By adopting a large flywheel of 40 mm diameter in the rotary head mechanism and introducing a powerful servo circuit, the tracing capability is improved and the trace deviation is reduced to less than half of the reference value. In addition, it is equipped with a servo function to keep the tape tension constant at the beginning and end of tape winding.

Each part is designed with high rigidity and vibration isolation. The weight class solid base realizes low center of gravity and vibration isolation structure to eliminate harmful vibration. Glass legs with excellent vibration isolation characteristics are used to suppress external vibration from speakers, etc.

The A/D converter uses a single-chip high-precision, high-speed integration type A/D converter that provides perfect LR balance.
The D/A converter uses a combination of a digital filter dedicated to DAT and a high-precision successive approximation D/A converter.

Equipped with an average / peak parallel standard meter with peak hold.
In addition, a digital peak margin indicator that shows the margin for the full bit level.

Equipped with a large FL display, it displays a level meter, program number, multi-counter, subcode indicator, digital peak margin indicator, etc.

It is equipped with two digital input / output systems, coaxial and optical.

When the digital input indicator is mounted and digital copying is possible, the indicator lights up. When a digital copy prohibition signal is recorded on the PCM-ID and when the sampling frequency is 44.1 kHz, the indicator blinks quickly. When no digital input signal is present, the indicator blinks slowly.

Equipped with convenient monitor functions for recording and editing.
The digital input signal is D/A converted and output as an analog signal, and the analog input signal can be monitored by D/A conversion immediately after A/D conversion.
It can be monitored not only during recording but also during stop.

It is equipped with long play mode which is ideal for long time air check, etc., and it can record and play back up to 4 hours continuously with 120 minute tape.
In addition, the play-only mode for music tapes is available in four modes that enable automatic switching between standard and wide tracks.

Equipped with timer start mechanism, recording and playback can be started at desired time by combination with separately sold timer.

The cassette loading mechanism adopts linear skating cassette loading.

Subcodes are supported.

Built-in functions such as cue, direct music selection, random access program, skip function, auto rewind function, introscan, blank search, repeat function, auto rec mute, etc.

The front panel is finished with lustrous alumite, and the side wood is finished with rosewood.

Wireless remote controller with 10 keys is included.
