Pioneer C-72 Operating Instructions - Page 4

FEATURES ABUNDANT AV INPUTS A total of five audio inputs, and five video inputs, with one video input on the front panel. SUPPLIED PROGRAMMABLE REMOTE CONTROL UNIT FOR MORE CONVENIENT OPERATION By using the program function, you can control other components (including other makers' components). CLEAN GROUND TECHNOLOGY Clean ground technology prevents noise on power line to flow to the signal ground line, permitting clean sound reproduction. MINIMIZED SIGNAL PATH DESIGN 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. LOCAL POWER OFF FUNCTION 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. EQUIPPED WITH A FIXED-OUT TERMINAL FOR SURROUND PROCESSOR CONNECTION TWO-TRANSFORMER MULTI-SUPPLY The control power supply 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. HIGH-QUALITY PARTS FOR HIGH-QUALITY SOUND 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. ALL-FUNCTION RECORDING SELECTOR The recording selector is equipped to handle all audio and video inputs, so you can record from any source while playing another. PRECAUTIONS DURING USE LOCATION Install the Control Amplifier in a well ventilated location where it will not be exposed to high temperture or humidity. Do not install the Control Amplifier in a location which is exposed to direct rays of the sun, or near to hot appliances or radiators. Excessive heat can adversely affect the cabinet and internal components. Installation of the Control Amplifier in a damp or dusty environment may result in malfunction or accident. (Also avoid installtion near cookers etc., where the Control Amplifier may be exposed to smoke from oil, steam or heat.) 0 PRECAUTIONS FOR INSTALLATION To ensure optimum sound quality, observe the following precautions: • This unit is heavy. Be sure to install it on a firm base which can support its weight. Also, to prevent the flow of cooling air from being blocked off, do not place the unit on soft material such as a carpet or cushion, or install it in a confined space. When installing the unit in a rack, provide adequate space around it to allow heat to dissipate. • To prevent the control amplifier from picking up noise due to leakage flux from the power amplifier when the control amplifier and power amplifier are installed adjacent to each other, install the control amplifier on the right of the power amplifier. Also, if you install the control amplifier above or below the power amplifier, place a partition between them to separate them by at least 4-inch (10 cm) from each other. • Install the unit on a level surface so that the feet of the unit are all touching the installation surface. 4
