* Pin Nos. 1, 2 and 3 are the output of the organ voice and
ORCHESTRAL TONES.
* The No. 6, No. 7, and No. 8 pins are open collector output with a rated
voltage of 5–30 volts DC and a maximum rated current load of 50
mA.
* Pin no. 11 detects the connection. If the nominal input voltage is
outside the acceptable range (18–30 V DC), the connection will not
operate correctly.
• The volume of the external speaker can be adjusted by
the VK-88's [MASTER VOLUME] knob.
• ROTARY [SLOW/FAST] button will switch the
rotational speed of the connected rotary speaker.
• ROTARY [BRAKE] button will temporarily stop the
rotation of the connected speaker. To resume rotation,
press ROTARY [BRAKE] button again, or press
ROTARY [SLOW/FAST] button.
If you do not want to output the Orchestral Tone from
the ROTARY TONE CABINET jack, press the
ORCHESTRAL TONES harmonic bars all the way in to
set the volume of the Orchestral Tones to "0," or select a
registration that does not use the Orchestral Tones.
