3.TECHNICAL DESCRIPTION
3.1 Power supply circuit
A voltage regulator circuit is provided to supply
constant voltage to the bias oscillator in the
amplifier block so that the bias oscillator is not
affected by voltage supply fluctuations. Power
supply to the motor is independent of the voltage
regulator circuit.
3.2 Amplifier section
The Dolby NR circuit employs IC element and
does not require adjustment. The emitter-follower
used in the headphone amplifier circuit ensures
sufficient volume even if the headphone impe-
dance is high. During recording and playback
the OUTPUT LEVEL control functions for only
the outputs from the LINE OUT and headphone
jacks and has no effect on the meter. During
recording, no output appears at the DIN output
terminal, but during playback an output inde-
pendent of the OUTPUT LEVEL control is
provided.
