FCircuit operation
(1)
Preamplifier
In the preamplifier input stage the pin 22 bias is the input
and the negative feedback virtual earth, and the bias for
the input stage transistor is taken from pin 22 via the tape
head to allow direct coupling. Connect a 1000pF capaci-
tor in parallel with the tape head to prevent high-frequen-
cy interference (see Fig. 2).
(2)
Mute amplifier
Preamplifier output muting can be switched on and off.
The mute is off when the mute switch input (pin 1) is low
or open, and on when the mute switch input is high (tied
to VCC via a resistor), see Fig. 3.
(3)
Equalizer
The preamplifier is based on an NAB120
µs NF-type
equalizer. It is possible to add a switching function for the
equalizer using the mute amplifier. Switching of the
equalizer constant is controlled by the voltage on pin 1
(low or high). Note, however, when this is done, preampli-
fier muting no longer operates (see Fig. 4).
(4)
Power amplifier
The power amplifier employs an NF circuit with fixed
gain. GVC = 36dB (BA3528AFP) and GVC = 27dB
(BA3529AFP).
For the input stage, the pin 22 bias point is the input and
the negative feedback virtual earth point, and the first
stage transistor bias is taken from pin 22. The built-in VREF
amplifier uses the same bias point as its input, and its out-
put voltage is about the same as DC output voltage from
the power amplifier. This becomes the virtual earth for the
headphones (see Fig. 5).
