Speakers
Neither speakers play
Check that the wires are properly connected. Check the audio mixer in RAV-Ware to ensure
the audio is routed to the loudspeakers.
Bass and treble are weak
Check the equalization for the loudspeakers in RAV-Ware.
Only one speaker plays
Check the equalization for the loudspeakers in RAV-Ware. Check the wires connected to the
speaker that does not play. Be sure the wires are in good condition and are firmly connected.
One speaker still does not play
Disconnect the wires from both the speaker and the mixer. Disconnect the other wire from its
speaker and connect that end of the wire to the speaker that doesn't play. If the speaker still
doesn't play, the problem is in the speaker. If the speaker now plays, continue checking for
the source of the problem. Disconnect the same wire from the mixer. Connect it to another
output. If the speaker plays, the problem is the original wire that was connected to that
speaker.
