PRA-1003
Control Amplifier was introduced as a control amplifier for the new era,
bringing into full play the operation factors of a tape deck which has come to
assume an important position as the program source. By introducing new
circuitry, it incorporates a high Signal-to-Noise ratio equalizer amplifier, low distortion,
and ultra wide range flat amplifier.
Input
capacitorless (ICL)
Low noise
FET parallel differential amplifier circuitry in the first stage, current
mirror differential predrive pure complementary PP output with emitter
follower, 14 transistors on one channel, high Signal-to-Noise 86 dB, and
equalizer amplifier
Phono 2 is
provided with an impedance change-over switch which will bring out the full
performance of the cartridge. Input terminals are all gold plated
Simultaneous
recording of 3 tape decks, 1 (2/(3 tape copy possible. Rec Function to meet the
are of real recording
