CIRCUIT DESCRIPTIONS 1.1 PLAYBACK FLOW The signal picked up by the playback head is (strobe) pulse is applied to pin 1, and PM3001 amplified by the equalization amplifiers, Q1701 then starts transmitting control signals from its and Q1703. At the same time, frequency response various output pins in accordance with which key is corrected. was activated. (Refer to Fig. 1-3.) The output from the equalization amplifiers is The following sections will describe the various level-adjusted by variable resistor VR1703 and circuit operations occurring when a mode key is then applied to Q1705. In addition to being an activated. Operations will be described for the amplifier, Q1705 also functions to correct fre- FWD direction of travel. (Except where other- quency response. wise specified, the pin nos. will be for PM3001.) When normal tape is used, Q1707 wiU be ON, The DOLBY MUTE circuit shown in the signal and the combination of Q1701, Q1703, and path diagram (Fig. 1-1) tums Q313 ON to mute all Q1705 will set equalization to 120ps. For metal or circuik only when the position of the Dolby CrO2 tape, Q1707 will remain OFF and equaliza- switch is changed. tion will be 70
