¥ 108,000 (around 1971)
Commentary
A stereo display that can observe various waveforms of equipment, check and measure characteristics, and comprehensively observe acoustic characteristics such as sound field characteristics of a listening room.
You can easily determine the antenna direction by connecting a tuner with a multi-path terminal.
In addition to being used as a VU level meter, the large level meter can also be used as an output meter or a voltage meter.
An input terminal for 4 ch is also provided.
