Description
 
It is the voice monitor system which incorporated and developed the amplifier of the all transistor system in 1964 (Showa 39) to the 2S-208 type speaker system which is acknowledged as a monitor speaker for broadcast.

The outstanding quality control and the stereophonic reproduction where sound was stabilized as an object for the sound quality surveillance of a stereophonic broadcast by simple composition are obtained.

The caster is united with the position of the lug where the height of the speaker sat on the chair by attachment.

Those days, many were used for NHK Broadcasting Center.

The tip of an input cord makes a canon connector a standard.
