Stereo Control Amplifier
The Pioneer C-72 has a total of five audio inputs, and five video inputs, with one video input on the front panel.
It is supplied with a programmable remote control for more convenient operation.
By using the program function, you can control other components (including other makers components).
Clean ground technology prevents noise on the power line from flowing to the signal ground line, permitting clean sound reproduction.
Relay and electronic signal switching keep the signal route as short as possible. By switching the Direct On/Off function On, the signal bypasses any sound quality adjusting circuitry, giving you the pure, unaffected sound.
When not using video and phono inputs, turn the video power circuit and the phono equalizer power circuit off in order to prevent them from collecting noise during playback of other sources.
The control power supply of the C-72 has its own transformer which is isolated from a second transformer having separate windings supplying the audio and video systems, so there is virtually no interference between them.
All parts used, including the newly developed motor-driven volume control, operational amp IC's, capacitors, resistors, printed circuit board and lead wires, were selected to assure high sound quality.
The recording selector is equipped to handle all audio and video inputs, so you can record from any source while playing another.
