English

If you are using terminal lugs, connect them to the wires. If you are
attaching bare wires directly to the speaker connectors, separate the
wire conductors and strip back the insulation from the end of each
conductor. Be careful not to cut into the wire strands. Unscrew (turn
counterclockwise) the speaker connector collar. Place the connector lug
around the shaft, or insert the bundled wire into the hole in the shaft.
Turn the collars clockwise to clamp the connector lug or wire fi rmly in
place.

NOTE: Be sure there are no loose wire strands that could touch
adjacent wires or connectors.

Troubleshooting

Most diffi culties in audio systems are the result of poor or wrong
connections, or improper control settings. If you encounter problems,
isolate the area of the diffi culty, check the control settings, determine
the cause of the fault and make the necessary changes. If you are
unable to get sound from the amplifi er, refer to the suggestions for the
following conditions:

Front Panel Power Indicator Is Not Lit

No mains power to the amplifi er. Check AC power connections at
the amplifi er and the AC outlet. Check the front panel power switch.
Make sure that it is set to the ON position. If using 12V trigger power-
on, make sure that a trigger signal is present at rear panel screw
terminals.

No Sound

If the amp is getting AC power, but is producing no sound, check
the PROTECTION INDICATOR on the front panel. If lit, see below. If
not, check all of your connections and control settings on associated
components. Make sure that your input connections and speaker
connections match your selected confi guration.

Protection Indicator Is Lit

The front panel PROTECTION INDICATOR is lit when the amplifi er
protection circuits have shut off the amplifi er. Typically, this occurs
only when the amplifi er has overheated, when there is faulty speaker
wiring, or after a period of extreme use. Turn off the system and wait
for the amp to cool. Then push the front panel power switch in and
out to reset the protection devices. If the problem is not corrected or
reoccurs, there is a problem with the system or the amplifi er itself.
