1) POWER Switch
This is the switch to turn the power on/off.
2) POWER Indicator
When the power is turned on, it lights up blue.
Right after the power is turned on, it keeps on blinking until the internal circuit is in a
stable condition and sounds will not come out during that time.
3) LOW CUT FILTER Changing Switch
If records with large warps are played, not only the music signals, but unnecessary
ultra-low region signals are inputted into the phono amp and the vibration board of the
low regional speakers will greatly shake back and forth and this may damage the
speakers or distort the sounds. In this case, by turning this switch on, it can attenuate
the ultra-low region signals and lessen the above phenomenon.
4) PLAYBACK CURVE Changing Switch
This is the switch that changes the playing equalizer characteristics.
The following three types of playing curves are installed. Switch according to the type
of record you want it to play.
-STEREO : RIAA curve for stereo LP playing
-MONO1 : Curve 1 for monaural LP playing (used on a DECCA label and
so forth : FFRR)
-MONO2 : Curve 2 for monaural LP playing (used on a Columbia label
and so forth)
