Kenwood KA-5002
(1971) is Direct coupling Stereo amplifier
and offering less power than some other stereo amplifiers, the 150 watt
(IHF) KA-5002 also manages to achieve a true audio eminence in the presentation
of pure sound. Superb frequency response and ultra-wide bandwidth with
lowest-possible IM distortion are achieved through the KA-5002's all stages
direct coupling circuitry and pure complementary-symmetry driver stage. All the
other thousand-an-one Kenwood quality extras are included to make this an ideal
stereo system.
Special features
All satges direct
coupling circuitry and pure complementary symmetry driver stage ensure superb
frequency response, ultra-wide power bandwidth, large damping factor, lowest IM
distortion, etc.
Improved NF type
equalizer circuit provides wide dynamic range.
2 dB step type
accurate tone controls for bass and treble.
Impedance selector
for phono input (30 or 50 kohms)
Exclusive null
balancer brings perfect left/right channel balance.
Tape monitor and
dubbing switch for 2 tape decks.
4 channel input,
output terminals and mode switch on the front panel.
Exclusive low level
phono input (0,06 mV)
Two pairs speaker
terminals and selector switch on the front panel.
Pre-amplifier output
and main-amplifier input jacks.
