SV-110
Commentary

A component-sized digital audio processor capable of digital copying between two VTRs.

When combined with VHS standard home video, up to 8 hours of digital recording / playback is possible in 3 x mode.
By connecting two VCRs, digital copying is possible taking advantage of the characteristics of the master tape, and the direction of copying can be confirmed by an indicator.

The digital signal processing circuit is equipped with large-scale LSIs (MN6601 and MN6602) that make full use of Technics semiconductor technology.
As a digital recording LSI with approximately 10,000 elements, the MN6601 adds error detection and correction codes to A/D-converted digital data and transmits it as a video signal.
As an LSI for digital reproduction, the MN6602, which integrates approximately 15000 elements, decodes reproduced digital signals and performs error correction, and supplies serial data to the D/A converter.

The SV 110 is equipped with a composite A/D and D/A converter and an LSI for recording / playback control.
The A/D / D/A converter is equipped with a 14-bit compound type A/D / D/A converter MA6196 that performs both A/D conversion and D/A conversion with a single IC, and the recording / playback control LSI uses MN6603.

Equipped with a Rec / Copy Muting switch, a signalless recording section can be made with one touch.
In addition, the unnecessary part of the recording source is cut and the silent part between songs is created. g It is red brain.

It has a linked recording volume that can be operated as a master volume.
It also has a balance volume that can adjust the balance of the left and right channels.

Equipped with 2-color FL level indicator.
Equipped with the peak hold mechanism of Oatley set / manual, the maximum level can be confirmed. The display range is -50dB to + 6 dB, and the overlevel is displayed in red up to + 6 dB.

Equipped with a VTR tracking check function.
Check the tracking status of the VTR by switching the FL level indicator, and adjust the VTR tracking knob so that the bar display reaches the maximum value.
In addition, it is equipped with a playback mode changeover switch which can select the optimum condition depending on the VTR tape to be combined.

Equipped with a playback mute release switch, enabling fast forward playback and rewind playback.

It is equipped with My Kujac interlocking line / microphone input switching.
