Description:
DC STEREO INTEGRATED AMPLIFIER
Information
1. Newly incorporated DC power amplifier* designed by
Kenwood offers extremely low distortion and phase
characteristics particularly in the range of very low
frequencies. Since a good transient response characteristic
is assured, output wave forms can be taken out without
impairing the original wave forms of input. The quality of
reproduced sound is very high.
* Refer to page 12 regarding technical descriptions of the
DC power Amplifier.
2. Because of the adoption of right and left separate power
supplies, each independent of the other, dynamic crosstalk
distortion is eliminated and excellent reproduction is
achieved with stable acoustic image.
3. Continuous power output is 60 watts per channel, minimum
RMS, at 8 ohms from 20 Hz to 20,000 Hz with no more than
0.02% total harmonic distortion.
4. Since an FET differential circuit is adopted in the first
stage, the Equalizer circuit assures a low distortion factor
and a high S/N ratio.
5. A BAX type low-distortion tone control and a tone defeat
switch designed to make up highly qualified sound are provided.
6. An ATT type master volume control (32 contacts) is
provided. It is carefully designed to reduce interlock
errors to a minimum.
7. Multi-Function Attenuator Switch
This lever instantly cuts the level by 20 dB.
For greater control with the large level control, simply
activate this lever and you will find precise level
adjustment easier and quicker. In addition, this switch is
practical when answering the telephone or to placate an
unappreciative guest.
8. A 2-stage loudness control is very convenient for
low-frequency correction.
9. Convenient tape switch with through circuit for two tape
decks.
10. Kenwood's excellence of design and superior
craftsmanship is evident not only in the electronics of the
KA-7100 but also in all the controls.
