The key lever will lock when pressed toward the head housing and lock disengaged when pressed away from the head. 5) Tape presence sensor If tape is completely wound onto the other reel or if it is broken during operation, this sensor will be activated to put the transport in the STOP mode whether it may be in any tape control mode. 6) Tension roller A shut off switch is linked with the left/right tension roller. If both the left and right tension rollers are at their extreme low positions, the transport will remain in the STOP mode even though the tape presence sensor detects that tape is loaded. 7) Idler roller Tach pulse for the tape counter is obtained from the left side idler roller. 8) POWER switch 9) Capstan and pinch roller The capstan is driven by a direct drive PLL servo capstan motor. 10) PITCH control switch and knob Tape speed can be varied approximately ±15% by the pitch control knob when the pitch control switch button is in the down position (left hand LED is lit). Coarse adjustment is by the outer knob and fine adjustment by the inner knob. 11) TAPE SPEED selector and LED A 2 speed selector. In the E-2, high speed is 38 cms (15 ips) and low speed 19 cm/s (7.5 ips). In the E-22, high speed is 76 cm/s (30 ips) and low speed 38 cm/s (15 ips). 12) METER selector and LED Selects CAL (calibration) or LINE OUT. The LED is lit in the CAL position (button depressed). As the input signal to the meter circuit CAL position is obtained from the point before the output level control, the line output level of the INPUT/SYNC/REPRO signals will differ from the meter indications depending on the output knob position. 13) BIAS 2 indicator A 2 position bias selector. Use the BIAS 2 position for tapes other than the recommended Ampex 456 tape. Refer to Page 12 for details. 14) Dump edit switch The EDIT switch is provided to facilitate splicing of tape after remov- ing any unwanted section of tape. When this switch is set to UP, the transport will be in normal operating mode, and when set to DOWN, the LED above the EDIT button will indicate the EDIT mode. When in the EDIT mode, the transport will not go into any other mode except PLAY and STOP. The capstan motor will rotate upon switching on the EDIT switch but the takeup reel remain stationary when the PLAY button is depressed. In this case, the mechanical brakes will be released but no power is applied to the takeup reel motor and the takeup reel can be easily rotated by hand. If EDIT is switched ON during the PLAY mode, tape will stop but if the PLAY button is depressed again, the tape will be transported at the play speed but will not be wound by the takeup reel. If EDIT is switched OUT under this condition, the transport goes to the stop mode. At this point, if tape slack is taken up so that the left and right tension arm is up, and then the PLAY button is depressed, the transport goes to normal play mode. 15) Counter display and tape speed display A five digit counter to display the hour, minute and second. For position display below the zero point, a is displayed in the hour digit. Furthermore, as long as the pitch control knob (10) is touched by your finger, the display will change from tape counting to tape speed and the percentage against normal speed will be indicated. 16) Record track selector The buttons for selecting the channel to be recorded and L is for left channel, R for right channel and CUE for time code channel. * If, for example, the "L" REC TRACK button is depressed, the red LED above the RECORD TRACK button, will blink to indicate the record ready state. Under this condition, if the PLAY and RECORD buttons are simultaneously depressed, the channel (track) of the depressed REC TRACK button will go into the record mode and the red LED change from blinking to steady lighting. * If the PLAY and RECORD buttons are simultaneously depressed without either of the REC TRACK buttons or CUE REC TRACK button being depressed, the RECORD LED at left of the RECORD button will light in green to indicate the record ready state. Under this condition, if the REC TRACK button is depressed, the LED above the RECORD TRACK button which correspond to the depressed channel, will light and the RECORD LED change color from green to red. If both L and R REC TRACK buttons or CUE REC TRACK button is released (cancelled) in the next step, the RECORD LED will change color to green thus changing from record mode to the record ready mode. With both L and R channels and CUE channel in record mode, and then, record mode of L channel only is cancelled, the RECORD LED will remain in steady lighting but the LED above the L channel RECORD TRACK button will be extinguished. 17) Monitor selector [INPUT/SYNC/REPRO] * If the INPUT button is depressed, input signals of channels L, R and CUE will go to the rear panel OUTPUT jacks and also be monitored by the meter. * If the SYNC button is depressed, depending on whether the recorder is in the r...
