Integrated Stereo Amplifier (1980-1981)
The Pioneer SA-9800 has the impressive feature which is the NSA (non switching amplifier), created specially by Pioneer.
This is a type of amplifier that adopts the merits of both class A and class B amplifiers, and it excels in keeping down the heat loss and allows the transistors to operate all the time in the active region.
For this reason, a high output power with a very low distortion factor is yielded all the way up to the high frequencies.
Power output: 100 watts per channel into 8Ω (stereo)
Frequency response: 5Hz to 100kHz
Total harmonic distortion: 0.005%
Damping factor: 55
Input sensitivity: 0.1mV (MC), 2.5mV (MM), 150mV (line)
Signal to noise ratio: 72dB (MC), 90dB (MM), 110dB (line)
Output: 150mV (line), 1V (Pre out)
Semiconductors: 3 x IC, 6 x FET, 73 x transistors, 36 x diodes
Dimensions: 453 x 155 x 425mm
