MONO OPERATION
As stated before, regular or balanced inputs can be used in stereo or mono. Connect a single
interconnect, either regular or balanced, to the left channel input of each amplifier. See the "Mono"
section above for complete details.
PROTECTION CIRCUIT
The Classé P-153 is equipped with rail fuses to protect the output drivers (GDB5, 5 amps
fast blow. fig.2, page 10). In the event that a short circuit or other problems would occur at the
output of the amplifier, one or more of these fuses may blow in an attempt to protect the amplifier. In
addition to the fuses, the unit has a circuit for the detection of unusual distortion characteristics
and/or DC content in the incoming audio signal. There is also an AC line fuse protecting the unit. It
is located at the back of the unit immediately to the right side of the AC receptacle (see fig.1, page
9).
If the protection circuit of the unit is triggered or any of the fuses has blown, the FRONT
PANEL POWER LED will go to BLINKING GREEN.
IF THE PROTECTION CIRCUIT HAS BEEN TRIGGERED, TURN THE P-153 OFF.
After the situation which triggered the protection circuit has been clearly identified and corrected,
attempt to re-start the unit. IF THE UNIT STILL GOES INTO PROTECTION MODE, OR IF IT
APPEARS THAT PROTECTION FUSES DID BLOW, CONTACT YOUR LOCAL DEALER.
DO NOT TRY TO CHANGE A BLOWN FUSE. REPLACING FUSES AND RE-STARTING
THE UNIT WITHOUT CHECKING FOR COMPONENT FAILURE COULD RESULT IN
FURTHER, SERIOUS DAMAGE TO VITAL COMPONENTS IN YOUR AMPLIFIER.
CONTACT YOUR LOCAL DEALER OR DISTRIBUTOR.
