Audio Problems
Caution
: Do not troubleshoot audio problems using headphones. Always be aware of the
volume levels on the PC4 and on the connected audio system or mixer.
Note:
When diagnosing audio problems, set the PC4 to play a Song Demo rather then
intermittently pressing keys. This will prevent any unexpectedly loud volume changes.
If there is no sound from your PC4, check if one of the following might be the issue:
ISSUE
The volume Slider is turned down.
REMEDY
Slowly push the volume slider up.
ISSUE
The volume control on the audio system or mixer is turned
down.
REMEDY
Slowly turn the volume control up.
ISSUE
The signal source selection on the audio system or mixer is
incorrect.
REMEDY
Set the volume of the audio or mixer to the lowest level, select
the correct signal source, and then slowly turn up the volume.
ISSUE
The audio cables are not securely plugged into the PC4,
audio system, or mixer.
REMEDY
Set the volume of the audio or mixer to the lowest level, securely
plug in the audio cables on both ends, and then slowly turn up
the volume.
ISSUE
The Destination parameter stops MIDI Data.
REMEDY
Change the Global Mode (MIDI page) “Destination” parameter to
USB+MIDI+LOCAL (see
)
ISSUE
The audio cable is of an incorrect type.

Obtain and securely connect an audio cable of the correct type.
The PC4 accepts both balanced (TRS) and unbalanced (TS) 1/4-
inch audio cables.
