Common Problems

Audio Problems

NOTE

: When diagnosing audio problems, set the Stage Piano to play its demo sequence.

If there is no sound from your Stage Piano, check the following:

¥ Stage Piano Volume/Controller slider turned down. Move the slider to the right.

¥ Volume control on audio system or mixer turned down.

¥ Signal source selection on audio system or mixer is incorrect.

¥ Audio cables not securely plugged in at both ends.

¥ Incorrect type of audio cable.

If you can hear sound but it is low or distorted, look into these possibilities:

¥ Audio cables not securely plugged in at both ends.

¥ Low voltage output from power module. Check Power Problems above.

¥ A received MIDI volume message has speciÞed a low volume.

¥ Current setup has set the Volume/Controller slider to a destination other than

Volume (Destination 7) or another Controller has been assigned to Volume.

¥ Input to audio system is set for low impedance instead of high impedance.

¥ Input trim to audio system or mixer is set too low.

NOTE

: The Stage Piano uses digital volume control via MIDI destination 7. For normal

operation, leave the default destination setting for the Volume/Controller alone. For best
signal-to-noise ratio, use the slider for small adjustments in volume and your audio system for
large adjustments.
