INITIAL TROUBLESHOOTING
Problem
1) Low volume or
distorted sound.
2) The amplifier does
not operate.
3) The 28-VDC output
cycles off and on,
or it remains off.

Check whether all the input and output connections
are properly made and securely fastened.
If the sound is distorted, check whether the speak-
ers are being overdriven (e.g., does the distortion
go away when the level control is turned down?).
Make sure that the power cord is plugged in and
that there is power in the outlet.
Examine the input and output lines for (1) obvious
shorts (among themselves and between them and the
chassis or surrounding equipment) and (2) broken
connections.
If everything appears in order, try replacing the
fuse. If the amplifier still fails to respond,
unplug the power cord and contact your local
Rauland distributor.
There are two circuit breakers protecting this
output. CB2 is a 1.6-Amp thermal breaker that
shuts down the circuit when the DC c u r r e n t flow
significantly exceeds the output's 1.2-Ampere rat-
ing,
then automatically resets.
It will continue
cycling off and on until the problem is corrected.
If the amplifier remains off, CBl (3.15 Amps) may
have tripped. Check for a short in the connec-
tions,
then try manually resetting CBl by poking a
small screwdriver through the access hole in the
front cover (at the upper left corner of the DAX6O,
or the lower left corner of the DAX120)).
If the problem does not lie in the load or the
connections,
one of the breakers may be defective.
Disconnect the load and call your Rauland distribu-
tor.
