FEATURES

1.

Front-loading with optimum convenience

All controls are neatly arranged on the front panel for easy operation.
Designed to provide excellent performance when used with any type of
Hi-Fi component system. The tape deck can be placed anywhere. even
on amplifier, tuner or receiver.

. Adoption of Dolby Noise Reduction System

The Dolby N.R. system eliminates undesirable tape hiss noise, im-
proving S/N ratio in high frequency range by about 10 dB.

. Unique tape selector switch

The tape selector switch functions to select bias" in 2 steps and e-
qualization in 3 steps to ensure optimum recording and playback of
various types of tapes, such as normal tape, L.H. tape, chrome tape
and Perri-chrome tape.

. input selector with MlC/DIN attenuator

The MIC/DIN attenuator built in the input selector protects the head
amplifier against saturation due to over-input; use the attenuator
according to the amount of MlC/DlN Input. The input selector allows
the line input to bypass the head amplifier, improving both S/N ratio
and distortion.

Full auto stop mechanism
in all mode such as recording, playback, fast forward or rewind, the
tape drive mechanism stops automatically as the tape reaches its end.

. Mirror and lamp in cassette compartment

A mirror and lamp furnished in the cassette compartment provide a full
view of the tape running condition.

. Satety-locked elect mechanism

Model KX~620 is provided with the safety-locked eject mechanism for
the tape ejection. When the cassette door is closed, the mechanism is
in effect and the cassette tape can not be ejected by pressing the
STOP/EJECT button.

. Free-to-change motor pulley

The tape mechanism is driven by DC motor, so the unit accepts both 50
Hz and 60 Hz power without making any modification.
