e 30 Hz slide control
Moving this slide control down reduces very low
frequency rumble, or compensates a warped disc.
Moving the slide control "Up emphasizes the very low
frequencies.
e 60 Hz slide control
Moving this slide control down reduces AC line hum
and (reduces) the lower tone. Moving slide control up
emphasizeslow tones such as 3 Pipe organ; drums,
bass, etc.
® 120 Hz slide control
This range supports the lower end ofthe music and
controls overall depth. The slide control may be
moved down to eliminated ' 'boomy bass" caused by
room acoustics.

This is the middle-to-lower tone range, but it has an
effect on the overall sound. Mainly, the richness of the
strings can be controlled. When strings are overly
warm under actual listening conditions, moving the
slide control down may help.
e 480 Hz slide control
|
|
This range is the foundation of music Aeludine both
instruments and the human voice and it controls the
overall power ofthe sound. As the slide control is
moved up, marange sounds will become more
forward. —
e 1 kHz slide control
|
This range affects the presence of the music (depth
of tone), and is especially effective when playing back
vocals. Moving the slide control up and down will
cause the vocals to be more ome front" or more
reserved.

è 2 kHz slide control
©
This is the frequency. range where the human ear is
most sensitive. Boosting the level slightly will add
brilliance, crispness, etc. to instruments. Cutting the
level slightly makes for easy listening.
® 4 kHz slide control
The human ear is also highly sensitive in this range.
Mainly effective for increasing/decreasing the
harmonics of the primary tone. Boosting this range a
bit makes strings more intense. Over-intense,
tiresome music becomes easy listening when the
slide control is moved down.
|
® 8 kHz slide control
High frequency range. Strings, horns, etc. will be
emphasized and this gives a slight difference in tone
glaze and quality. Moving the slide control down
reduces over-emphasized consonants in vocals and
objectionable tape hiss. Moving the slide control up,
on the other hand, improves the sharpness of such
instruments as cymbals.
© 16 kHz slide control —
Super-high frequency range. This affects high
harmonics rather than the fundamental tones of the
instruments themselves, and.has an effect on the
delicacy and atmosphere of the music. Maving the
slide control up adds a delicate, fresh sound to
cymbals, triangles, etc.
@ OUTPUT LEVEL control
This controls LINE OUTPUT level of this unit.
* REC OUT level cannot be changed.

@ EQUALIZER MODE switches
Selects the equalization mode.
'DEFEAT: No equalization — flat response iS-
achieved.
ON: The equalizer control indicators light up and
equalization can be effected.
REC: The signal routed to the Rec Out terminals i iS
equalized.
@ TAPE monitor switch
Used to select a tape deck for tape monitoring.
2-50 OU
@ SUBSONIC FILTER switch
|
This switches the subsonic filter on'and off to cut
frequencies in the 15 Hz range as selected by the
SUBSONIC FILTER controls.
© PINK NOISE switch _
|
Pink noise, which is emitted. by a built-in generator, is
a random noise signal which is distributed at an even
level at all frequencies, and when monitored through
'the supplied microphone, allows you to measure the
acoustic response characteristics of the listening
environment.
:
@ MIC jack
This is the input terminal for the microphone to be
used with the spectrum analyzer to measure the
acoustic response characteristics of the listening |
environment.
@ POWER switch
This switch turns the power to this unit ON and OFF.
The switch is pressed once to turn the power on, and
a second time to turn the power off.
