Form Stereo power amplifier
* It is a build-out value at the time of driving both channels simultaneously.
An output and a distortion
(An 8-ohm load intensity, sine-wave input) It is 0.01% or less at the time of 100Hz and 100W output.
It is 0.01% or less at the time of 1kHz and 100W output.
It is 0.01% or less at the time of 10kHz and 100W output.
Output internal impedance It is 3.3 microhenries to 0.03 ohm and a single row.
Offset voltage 7mV or less
Frequency characteristic (1kHz criteria) Low-pass: It is -1dB at 20Hz.
High region: It is -3dB at -0.1dB and 50kHz in 20Hz.
Input sensitivity 0.5V (at the time of 8-ohm load-intensity and 100W output)
Input impedance 20kohm//220pF
Slew rate 0.1v/microsecond
The maximum input limit If an input signal is to +20dB, it returns in an instant.
Crosstalk (at the time of the input load intensity of 1kohm) 80dB (100Hz), 70dB (1kHz), 60dB (10kHz)
SN ratio - 96dB (at time of A correction)-93dB (with no correction)
Power-source input 100-130V, 200-250V, 50 to 60 Hz
