Connecting to an External Audio System
2-5
Your SPS4 features Left and Right audio input jacks for connecting to external signal sources
such as CD or MP3 players or a second keyboard. The audio input signal is mixed with
the SPS4’s own signal then the mixture is sent to the speakers, headphone jacks, and audio
output jacks. Note that the VOLUME slider only affects the volume of the SPS4 signal.
The Audio Input jacks are balanced so if your signal source has a balanced output and
balanced cables are used to connect, extraneous noises such as power line hum, are greatly
reduced.
