McIntosh C31V a price point -- unknown (release time -unknown)

Audio-video control amplifier which carried the voice input of an image system and was attached in remote control.

An input/output of an audio & video system is controllable with remote control.
Moreover, when MCD7005 and memory-read7082 are connected, it is also possible to operate those equipments.

Functionalities, such as a strange loudness control common to L/R for which 5 band special-NetWare-program equalizer and a succession are good, and low & high filter, are carried.

As for black alumite finish and a chassis, the lower of gold / green illumination, and the front panel of the front panel upper portion is a glass (black) with black finish at the aluminum panel.
