Audio Database Technics SU-8011 34,800yen(around the 1979 time) Description �@ The Integrated Amplifier which carries a high speed of response light emitting diode power indicator and a mic mixing circuitry. The light emitting diode power indicator which displays a music signal by five light emitting diodes each arranged symmetrically and whose speed of response is 200microsec is carried. The low distortion and the low noise design which inherited the thought of the concentrated power block of 99A (SU-8099) are adopted. Rating of a mode Form Stereo Integrated Amplifier Effective output (both channel drive) 25W+25W (8 ohms, 40Hz - 20kHz) Output bandwidth (both channel drive, 8ohms) 10Hz - -50kHz three dB THD 0.1% Frequency characteristic Phono:RIAA standard curve �}1.0dB Tuner, Aux: 10Hz - -80kHz three dB SN ratio (IHF-A) Phono:80dB Tuner, Aux, Tape: 97dB Tone control Bass: �}10dB (50Hz) Treble: �}10dB (20kHz) Power source AC100V, 50Hz/60Hz Power consumption 55W Dimensions Width 430x height 97x depth of 240mm Weight 5.0kg
