A four-channel play can be enjoyed by connecting with amplifier with a tapes monitor switchpoint.
By a function switch, the sound field effect united with the sound-recording scheme of the source, eye music, and a difference and liking of an organization can be chosen.
The phase modulation circuit is carried, the phase difference signal (indirect sound and reverberation component) which changes every moment and is transmitted from rear in a hole is reproduced, and sound field like a concert hall can be reproduced by synthetic with the sound of a front.
In order to obtain natural sound field, the IC-ized pure electronic-circuitry scheme is adopted.
The semi- complimentary ITL-OTL scheme is adopted as rear amplifier.
The protection network with an immediate judgment fuse is carried.
Two kinds of placements (2-2 scheme, two to front 2 scheme) are possible for a rear speaker by eye music or organization.
A switchover of a switchpoint can compare two schemes.
