SOUND ON SOUND
The second alto recording is adjusted with the VOLUME CONTROL KNOB (LEFT) @, watching the left VU meter
@.
The
leve! of the right VU meter @ indicates the first soprano recording.
(3)
After completing the second recording, this portion should be rewound.
Then the third track is played and a duet of soprano
and alto can be heard.
When the first track is played, the soprano, alone can be enjoyed.
ln the same manner, when the first and the third tracks
are interchangeably selected (by the track selector), such recording of sound on sound can be made repeatedly, thus one can
enjoy recording of even quartet or sextet singing.
19. TRANSISTOR PROTECTION
The S. E. P. P. O.
T. L.
system is used to protect the output circuitry of the M-9, (M-9DX) main amplifiers. The output impedance
should be 8 ohms.
If a speaker of Jess than 8 ohms impedance is used or if the speaker terminais are accidentally shorted, the
protector fuse will blow to protect the transistors.
Transistors are easily damaged by excessive Joad or high ambient temperatures.
If the protector fuse has blown, the sound may be distorted or there may be no sound at ali.
The protector fuse may be replaced
with special 1.0 A fuse.
