DC Integrated Pre Amplifier (1978-81)
Although it is the basic role for an amplifier to amplify the music signals faithfully, this is in actual practice hard to be carried out.
Music signals are, as you know, the wave signals that are never repeated, therefore, not only the wave form but the time lag (phase characteristics) must be considered for the high fidelity amplification.
We have titled the 5C50 with the indication Real Time Processed, since we have been delving into the phase characteristics and obtained a satisfactory solution.
We have adopted a DC-amp configuration in order to improve phase distortion in low frequency as well as transient distortion in high frequency range.
Also several measures have been bestowed to eliminate non linear distortion which appears only at the time of actual use, when connecting cartridge etc
Frequency response: 1Hz to 200kHz
Total harmonic distortion: 0.005%
Input sensitivity: 2.5mV (MM), 150mV (line)
Signal to noise ratio: 80dB (MM), 100dB (line)
Output: 150mV (line), 1V (Pre out), 18V (Pre out Max)
Dimensions: 442 x 400 x 101mm
