30. recisely using the bias and recording level calibrating function Bias calibration Too high a bias level gives a rolled off high frequency response and too little bias reduces the signal to noise ratio and increases distortion To adjust the bias current to the level which gives the best possible frequency response proceed as follows 1 Insert the cassette to be recorded 2 Press the appropriate TAPE button according to the type of tape 3 Play the program source For easier bias calibration choose a monotone as a source pro gram such as the calibration tone generated by the oscillator built in the FM AM tuner if provided 4 Press the REC and gt buttons to start recording 5 While recording press the MONITOR switch to TAPE and adjust the BIAS control so that the recorded sound heard is as identical as possible to the source sound BIAS Sa Y Bias reduced 4 a Bias increased high frequencies boosted iD high frequencies suppressed Y Ww 20 UF 20 Recording ievel calibration The Dolby NR function is most effective when the recording level and the playback level are the same After completing the bias calibration calibrate the recording level as follows Tape sensitivi ty will be compensated for automatically 6 Adjust the REC CAL controls so that the peak program meters deflect to the same point and the recorded sound heard is as close as possible to the sound heard when the MONITOR switch is pressed
31. s locating the very beginning of the selection while the recorded sound is being heard in rewind or fast forward mode The dual speed rewind and fast forward functions allows you to rewind and advance the tape more rapidly than by the normal re wind and fast forward speed A digital linear counter indicates the elapsed recording or play back time in minutes and seconds and also indicates the remain ing recording time with a minus sign The pre end winker system gives warning that the tape is nearing the end during recording in which case the digits displayed on the tape counter flash on and off The FL display peak program meters follow the transient peaks of the music and maintain the peak readings for about 4 seconds OPERATING VOLTAGE Before connecting the unit to the power source check that the operating voltage of your unit is the same as the local power line voltage The Continental European model Type 1 operates on 220 V ac or 240 V ac adjustable by authorized Sony personnel The United Kingdom model Type 2 operates on 240 V ac or 220 V ac adjustable by authorized Sony personnel The Canadian model Type 3 operates on 120 V ac The model for other countries Type 4 operates on either 110 120 220 or 240 V ac The voltage selector is located on the rear panel If the selector must be reset disconnect the ac power cord and turn the selector with a coin so that the arrow on the selector points to the appropria
