TECHNICS SH-3434 with WOOD BOX Audio Scope 4 Channel Visual Control Center + Remote SH-1010 Vintage 1973 WORK Good Look
Working On 220/240 Volts
Technics SH-3434 + SH-1010 (Remote Control)
Very RARE (around 1973)
In addition to the discrete AFD control function on the SH 3400, it also incorporates an AFD scope that allows you to visually check the 4 ch sound field. This is a full-scale control center for the 4 ch era.
It uses a unique AFD scope that allows you to visually confirm the sound field of the four channels. This allows you to make adjustments such as phase switching, volume, and front-back balance necessary for precise four channel playback.
It can be used not only for 4-channel sound fields, but also for waveform check of each channel and for oscilloscope for observation.
The discrete sound field can also be controlled freely.
Equipped with a phase selector switch.
It is equipped with recording and reterminal for 4 ch tape deck.
