Although the PDP-400 is a self-contained musical instrument that simply be
plugged into the AC mains outlet and played, it also features a number of connec-
tors for system expansion.
The Connectors
●
AUX IN L and R Jacks ............................................................................................................................
These jacks are intended primarily for use with external synthesizers or tone
generator modules.
For example, the outputs of the synthesizer/tone generator can be to the PDP-
400 AUX IN jacks, allowing the sound of the synthesizer/tone generator to be re-
produced via the PDP-400’s internal amplifier and speaker system.
●
AUX OUT L/L+R and R Jacks ................................................................................................................
The AUX OUT L/L+R and R jacks deliver the output of the PDP-400 for con-
nection to an instrument amplifier, mixing console, PA system, or recording equip-
ment. If you will be connecting the PDP-400 to a monaural sound system, use only
the L/L+R jack. When a plug is inserted into the L/L+R jack only, the left- and
right-channel signals are combined and delivered via the L/L+R jack so you don’t
lose any of the PDP-400’s sound.
CAUTION
• The AUX OUT jack signal must never be returned to the AUX IN jacks, either
directly or through external equipment.
●
MIC. Jack, MIC. VOL. and REVERB VOL. Controls .............................................................................
A standard microphone with a 1/4" phone plug can be connected to
the MIC. jack. The microphone sound is then mixed with the PDP-400
sound and delivered via the PDP-400’s speakers. The MIC. VOL. con-
trol can be used to adjust the microphone volume, and the REVERB
VOL. control can be used to adjust the depth of the reverb effect applied
to the microphone sound.
●
MIDI IN, THRU and OUT Connectors ....................................................................................................
The MIDI IN connector receives MIDI data from an external MIDI device
(such as a synthesizer, sequencer, music computer, etc.) which can be used to con-
trol the PDP-400. The MIDI THRU connector re-transmits any data received at the
MIDI IN connector, allowing “chaining” of several MIDI instruments or other
devices. The MIDI OUT connector transmits MIDI data generated by the PDP-400
(e.g. note and velocity data produced by playing the PDP-400 keyboard).
More details on MIDI are given in “MIDI Functions” on page 47.
NOTES
• The input signal from the AUX IN jacks is delivered to the AUX OUT jacks, but is
not affected by the PDP-400’s volume control or reverb effect.
