FUNCTION SELECTOR SWITCH The Function Selector Switch selects the desired type of program source to be heard thru your system. 1. PHONO: Selects your record player for stereophonic operation. 2. AUX: Selects any program source such as an AM tuner, the output of your television set, a 2nd tape recorder or any other high level equipment connected to the AUX receptacles on the rear of your receiver. 3. FM MONO: Selects the FM section of your receiver. In this position you can listen to stereophonic broadcasts monophonically while monophonic broadcasts will appear unchanged. 4. FM AUTOMATIC: This is the normal listening position for all monophonic or stereophonic FM broadcasts. In this position the stereo indicator and automatic switching circuit built into your receiver are operative. For further details see the paragraphs on "Stereo Indicator" and "Selecting Monophonic or Stereo FM Broadcasts". 5. MIC RECORD: Selects the Tape Recorder when you wish to make a recording using microphones only. Note: When playing pre-recorded tapes the Function Switch has been bypassed and may be in any position. See paragraph on "Mode Switch." TUNING METER Your Nocturne Receiver incorporates a D'Arsonval movement tuning meter for precise and accurate tuning. For FM Tuning: The meter is designed to operate on a null or "zero" center principle. Therefore, the meter pointer should always be at the dead center position of your meter dial for optimum listening performance. To accomplish this, rotate your tuning knob slowly, in one direction towards the station of your choice. As you tune through the station you will notice the pointer swinging from the left or right past the zero center. THE CORRECT POINT for minimum distortion and optimum FM reception is when the pointer is resting at the "zero" center position. TUNING The tuning knob, located directly to the right of the dial glass is used to select the desired station when your selector switch is in the FM mono or FM automatic positions. SELECTING MONOPHONIC OR FM STEREO BROADCASTS Under normal use for all FM broadcasts the function Selector Switch should be placed in the FM Automatic position. Your receiver is equipped with a stereo sensing circuit which can automatically determine if your unit is receiving monophonic or stereophonic broadcasts, and then automatically adjust the mode of operation. If the station is transmitting stereo, your receiver will automatically switch in the multiplex section and you will hear the broadcast in full stereo. Should the station conclude broadcasting in stereo, your receiver will automatically switch back to monophonic reception. 8 Should you receive a weak stereo signal whose quality has been degraded by noise or poor signal conditions, and you wish to listen to this stereo broadcast, monophonically, place the function selector switch in the FM MONO position. STEREO INDICATOR A stereo indicator is located directly behind the FM dial glass and operates in conjunction with the FM AUTOMATIC position of the Function Selector switch. The indicator visually shows the reproduction of FM stereo through your receiver. To tune for FM stereo proceed as follows: 1. Place the function selector switch in the FM AUTOMATIC position. 2. Tune to the station of your choice using your tuning meter for precise and accurate tuning. Your stereo indicator will now show if you are tuned to a stereo program. If the indicator is OFF, the program you are listening to is being broadcast monophonically. DIAL SCALE The Dial Scale on your TDC33 is marked with two (2) scales, an FM frequency scale (88-108 MC), and a logging scale (0-100). Since most FM stations operate on frequencies which are not whole numbers (such as 96MC as compared to 96.3) ideally each megacycle division on the frequency scale should be divided into 10 parts to enable the user to pinpoint the location of the station. This would require a dial scale which would be longer than the front panel. The logging scale which is divided into 100 equal parts provides a means of finding your favorite station, once you have noted its position on the logging scale. For example, in New York City, WQXR operates on 96.3 MC. After locating this station through the use of the frequency scale (between 96 and 98 MC), you find that the pointer may fall on 50 on the logging scale. Make a note of this setting. For future tuning to WQXR simply set the pointer to 50 on the logging scale. TAPE RECORDER OPERATION PROCEDURE Every control on this stereo tape recorder serves a specific function and is important to the operation of your stereo music system. PLEASE READ the following section carefully to assure full advantage of the performance capabilities of your tape recorder. SUPPLY REEL SPINDLE: To record or play back, place the full reel of recording tape on this spindle. Additional information on the supply reel spindle is contained in paragraph "Threading the Tape". TAKE-UP REEL SPINDLE: See Paragraph "Threading the Tape". TAPE SPEED SELECTOR: This is the lever you will use to select the speed you require for playback or recording, namely, 7 1/2 , 3 3/4 or 1 7/8 IPS (inches per second). For quality music recording, it is recommended that 7 1/2 IPS speed be used. For voice recording, a slower speed may be selected, such as 3 3/4 or 1 7/8 IPS. NOTE: Before changing from one tape speed to another, be sure that the power for the recorder is "ON" and the tape "function switch" is in the STOP position to eliminate excessive wear to the drive mechanism.
