The LED indicator above the voice selector will light to indicate which voice is currently se- lected. The PDP-300 also has a DUAL mode in which two voices can be played simultaneously across the full range of the keyboard — see page 7 for details.
OPTIONAL IN L/R and OUT L/R Jacks The Optional Out jacks can be used to deliver the output of the PDP-300 to an external keyboard ampli- fier or stereo sound system. On the contrary, the Op- tional In jacks can be used to reproduce the output of another instrument such as cassette tape recorder through the PDP-300’s built in speaker.
Pressing the C7 key more than twice in the PDP-300 causes all the demo tunes to be played in se- quence and repeated until the demonstration is stopped by pressing the [MIDI/TRANSPOSE] button again.

5. Distorted Sound When the PDP-300 is Connected to An External Amplifier/Speaker System If the PDP-300 is connected to a stereo system or in- strument amplifier and the sound is distorted, reduce the setting of the PDP-300 volume control to a level at which the distortion ceases.
