°ifb•'e.}..^ Precautions_ The STR-GX40ES, STR-GX50ES or STR-GX60ES is a receiver which controls audio and video sources. The unit allows you to switch easily among a variety of audio/video programs. Amplifier • Optical Legato Linear A System allows the receiver to operate automatically as a class A amplifier when the level is low and as a class B amplifier when the level is high without disturbing the sound signal. This minimizes total harmonic distortion at every sound stage. • These receivers have a spontaneous twin drive power circuit. Condensers having large capacity are used independently for the voltage amplification drive stage of class A and power output stage of class B. Thus, a stable output and high quality sound are obtained, resulting in exclusion of power interferences. The class A stage realizes a stable operation free from interference of the power stage even when an instantaneous or strong output is received. • A source direct switch is employed to reproduce high fidelity sound. Any source can be reproduced without passing through the circuits of tone control, loudness switch and balance control. Tuner • Precise tuning is obtained thanks to the quartz-locked digital synthesizer system. • A total of 30 FM/AM stations can be preset in 3 memory pages (A, B and C) that allow you to classify stations. On safety • Operate the unit only on 120 V AC, 60 Hz. • Should any solid object or liquid fall into the cabinet, unplug the unit and have it checked by qualified personnel before operating it any further. • Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself. • One blade of the plug is wider than the other for the purpose of safety and will fit into the power outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer. On operation • Before making program source connections, be sure to turn the power switch off and unplug the unit. • When the unit is not used, turn the power off, to conserve energy and to extend the useful life of your unit. On cleaning the cabinet Clean the cabinet, panel and controls with a soft cloth lightly moistened with mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent such as alcohol or benzine. For the customers in the U.S.A. For detailed safety precautions, see the "IMPORTANT SAFEGUARDS" leaflet. If you have any question or problem concerning your unit, please consult your nearest Sony dealer. Remote commander • The remote commander allows you to control most of Sony's audio equipment from a distance. • The programmable remote commander supplied with the STR-GX60ES is also equipped with an infrared ray transmitter/receiver which allows it to "read" and "store" control information from other remote commanders. This includes the commander produced by manufacturers other than Sony. 4
