OTHER CONTROLS CIRCUIT PROTECTION -SPEAKER PROTECTOR -1 I LEFT -16 OHMS -- I SPEAKER SYSTEM - 2 iirr ow QOM NKr I Nt/ • AC FUSE 4A3Ac r. By far the most frequently used controls are FUNCTION, VOLUME, and POWER; but each of the controls we haven't yet mentioned has a specific purpose. Listen to their effect as we describe them. TREBLE Raises (clockwise) or lowers (counterclockwise) high frequency content in program material on both channels simultaneously. Neutral position is 12 o'clock. BASS Same effect as TREBLE control. except works on low frequencies. CONTOUR Works in conjunction with VOLUME control to increase bass energy at low volume settings. Progressively less effect as volume level is increased. The CONTOUR switch has no effect at VOLUME control settings beyond 12 o'clock. TAPE MON-1, TAPE MON-2 Admit programs Porn any high level' source (usually tape recorder) connected to TAPE MON receptacles. They DO NOT affect U• .-:ppearing at the TAPE OUTPI ru.ceptacles. Thus, the use of the TAPE Mc'N switches does not disturb the recording process of whatever source the FUNCTION switch is set. (Note: If the rear panel TAPE MON inputs are unoccupied and either TAPE MON switch is depressed. no sound will be heard regardless of the position of the FUNCTION switch. The same will be true if the equipment connected to the TAPE MON inputs is off). TAPE MON also allows for connection of signal processing devices. MONO Changes any program from stereophonic to monophonic format. Also processes any single channel source connected to a single input receptacle (such as television sound) through BOTH channels. Disables red STEREO beacon light. HI CUT A filler to reduce high frequency content of any program material. Tape hiss, record scratches and other problems found in program material can be effectively reduced with this switch. LO CUT A filter to reduce low frequency content of any program material. Rumble from your turntable (if present) of other low frequency problems can be effectively reduced with this switch. PHONES Receptacle for headphones for private listening. Does NOT automatically defeat speaker systems. Headphones can be used whether your speakers are on" or `off". FUNCTION Selects programs for playback through system. Same signal appears al both TAPE OUT receptacles. Two circuit breakers and an AC power fuse are provided to protect the 730. The circuit breakers are labelled SPEAKER PROTECTOR and protect the amplifier circuitry from external short circuits or other conditions that would cause excessive current to be drawn through the amplifiers. If one of your speakers stops reproducing. sound first check the connections for that speaker, correcting any short circuit condition. (Wire strands touching the wrong terminal are the usual cause.) Then locate the circuit breaker for that channel . Press the reset button firmly and release immediately. DO NOT hold button in. The AC fuse protects the entire receiver from excessive current through the AC power line. Should this fuse blow: THE REPLACEMENT FUSE MUST BE PRECISELY THE SAME TYPE AS THAT SPECIFIED ON THE REAR PANEL. USING ANY OTHER FUSE WILL NOT PROTECT THE 730: SERIOUS DAMAGE TO ITS CIRCUITRY CAN RESULT. CLEANING THE DIAL GLASS Dust or smudges can be removed from the dial glass with a diluted liquid glass cleaner and a soft cloth or damp paper towel. DO NOT use a strong solvent-type cleaner or ammonia as these may remove the lettering on the face panel or cloud the dial glass.
