M@ REAL TIME SPECTRUM
ANALYZER
*This can be used to measure and correct the sound field
frequency response of a listening room
and to measure
the
frequency components
of a sound
source.
eThe
same
12-band
frequency divider as for the band
level
controls
allows the levels of the frequency
components
of
voices, music, etc., to be visually displayed.
The "full range" area on the right side displays the combined
level of all of the frequency
bands.
The display is in 12 points for each frequency band and a level
width of 30 dB can be displayed.
-qualizer on/off selector
Rec mode selector
( m straight, = EQ)
* Dubbing from tape deck 1 to 2 is possible with tape 1 switch.
** Dubbing from tape deck 2 to 1 is possible with tape 2 switch.
AC outlet (unswitched)
For [XA,PE and PA] area only
Voltage selector
{on the bottom board)
*The real time spectrum
analyzer is connected
to the output
terminals of this unit. When the equalizer switch is '"'on", the
level of the corrected
source
is displayed;
when
pink noise
switch is "on", the level of the corrected
pink noise is
displayed; when the microphone is connected, the microphone
input level is displayed.
The
attack time and recovery time of the display is fast for
source and slow for pink noise; thus the responsiveness to the
'source is good and the display is easy to see during sound field
correction.
