Amplifier will not power up
If the front meter is not illuminated, follow the procedure outlined below. If one step
succeeds in activating the power, stop there and ignore the other steps.
1.
Push the power switch on the front underside edge of the amplifier.
2.
Check to make sure the AC cord is plugged into the wall outlet.
3.
Check at the back of the amplifier to make sure the 15-amp IEC connector is
pushed all the way into the jack on the back of the amplifier.
4.
Check to see that the fuse is blown. Replace with same type and rating only.
(In US, use only a 10 amp, slow-blow fuse.)
5.
Check your household electrical box to make sure the circuit breaker has not been
tripped. If it has, flip the breaker back on.
6.
If the breaker trips again, check the speaker cable connection on the amplifier and
the speaker to make sure that the terminals are not shorted, and check the entire
length of the cable to ensure there has been no damage to it.
7.
If all of these steps fail to return power to the amplifier, consult your dealer for service.
Front meter is illuminated but you hear no sound
Follow these steps in order. If one step succeeds in restoring the sound, stop there and
ignore the other steps.
1.
Check your preamp and source device to make sure they are both turned on.
2.
Check the source device to make sure it is playing, i.e., if it's a record player, make
sure it's spinning and the tonearm is lowered, or if it's a CD player, make sure it's in
play mode and not in pause.
3.
Make sure your preamp is not muted and that the desired source is selected.
4.
Check the line-level connections between the source device and the preamp,
and between the preamp and the amplifiers. Reconnect any cables that may
have become disconnected.
5.
Check the cables between the amplifiers and the speakers to make sure they are
properly connected and that the cables have not become damaged.
