Names and Functions
1. Operation switch (OPERATION)
Toggles the power on and off.
When wiring or connection is performed, be sure to turn off
this switch. When turning on the power switch again after
turning the unit off, wait for more than one minute.
(It takes more than 30 seconds for the time mute to be reset
again.)
2. Low frequency selector switch
(FREQUENCY/Hz)
Selects a turnover frequency of the tone control for bass
from 150 Hz, 300 Hz, and 600 Hz.
For example, when 150Hz is selected, the frequencies of
150Hz and lower can be adjusted by the tone control for
bass.
3. High frequency selector switch
(FREQUENCY/Hz)
Selects a turnover frequency of the tone control for treble
from 1.5 kHz, 3 kHz, and 6 kHz.
For example, when 1.5 kHz is selected, the frequencies of
1.5 kHz and higher can be adjusted by the tone control for
treble.
4. Tone defeat switch (TONE DEFEAT)
Bypasses the tone control circuit.
OFF: Setting the switch to this position activates the
tone controls and enables the user to adjust
preferred tonal balance.
ON: Setting the switch to this position bypasses the
tone control circuit. At this time, operating the
tone control will not change the tonal balance.
5. Low cut switch (LOW CUT)
Toggles the low-frequency cutoff function on and off.
OFF: Provides the normal state.
ON: Cuts low frequencies below 30Hz at a –6dB/
octave slope.
* This is useful when the woofers of speakers vibrate due to
the warped record during record playback.
6. Mode switch (MODE)
Changes the output mode.
MONO: Mixes the signals from right and left channels.
STEREO: Provides normal stereophonic playback.
