ROTEL RX-200A
35,800yen(around the 1970 in-the-early time)

Description
 
The stereo receiver which can enjoy four channels at the expense of the minimum by a speaker matrix.

a speaker matrix scheme is carried out to if I will sound the phase difference signal component of the right-and-left sound of the conventional two-channel stereo from the speaker of rear, and direction is expressed by preparing this rear circuitry.

Two speaker output-terminals are carried. These outputs can be turned on and off by the push-button of the front panel.
Moreover, a four-channel play of a speaker matrix scheme can be enjoyed by switching the switchpoint of a rear panel.
