Connections
This section takes a brief look at the types of connections that can be achieved using the rear-panel sockets.
POWER
Mains: Connect the optional power supply plug to the rear-panel 12 V D.C. jack and the other end to a suitable
wall outlet.
Batteries: Insert 8 “torch” batteries (alkaline, 1.5 volt “LR-20”) into the battery compartment located under the
instrument.
AUX OUT (STEREO)
The rear-panel AUX OUT jack is a stereophonic output for connection of the PK7/PK5 to an amplification
system (keyboard amplifier, domestic stereo system, mixing console, etc.). The signal is delivered processed
by the instrument’s internal effects processor.
For stereo reproduction, use a cable consisting of a stereo jack at one end and two mono jacks at the other
(Left, Right). The type of jack required also depends on the external amplification equipment. To exclude the
instrument’s internal amplification and use the audio outputs only, insert a jack into the headphones socket.
Connecting AUX OUT to external amplification equipment does not exclude the internal speakers.
INPUT - (MIC/LINE + GAIN) [OPTIONAL FOR PK7 ONLY)
Mic/Line + Gain
The Mic/Line jack and the sampling input are situated on the optional Audio Video Interface (AVI).
Microphone and/or Line signals (musical instruments) are accepted and can be processed by the internal
effects processor.
Samples can also be memorized to the Sample-RAM, regardless of whether the AVI is installed or not.
The Gain control regulates the level of the input signal before entering the system.
With the MIDI/GENERAL function, it is possible to change the ON/OFF status of the microphone and relative
volume (00-127).
MIDI
PK7/PK5 is fitted with a standard MIDI interface consisting of the MIDI IN and MIDI OUT ports for MIDI connec-
tions. Detailed information regarding MIDI applications are found in the dedicated chapter further ahead.
Below follow brief instructions on the principal MIDI connections possible.
• PK7/PK5 piloting another instrument.
Connect the PK7/PK5 MIDI OUT to the MIDI IN of the other instrument.
• PK7/PK5 piloted by a master keyboard.
Connect the PK7/PK5 MIDI IN to the MIDI OUT of the master keyboard. For the master keyboard to
simulate the PK7/PK5 keyboard, set it to transmit on the same channel as the PK7/PK5 Common Channel,
setting all other channels to off.
WARNING - Be sure to turn
down the volume of the ex-
ternal amplification system
before connecting audio ca-
bles. Inserting jacks into the
connectors can cause noise
which may damage the
speakers of the amplifica-
tion system.
