RED POWER LED off.
The unit is not turned-on. Push-in POWER
button or use remote turn-on remote control. Is the power cord plugged
into both the back of the unit and into a suitable power outlet? The
simplest way to check for power at the outlet is to unplug the amp and
plug in a light.
-
There is no output.
Has the unit warmed up? It takes about 30
seconds from when the POWER button in pushed in. Is the MASTER VOLUME
turned-up? (Never start with it turned up - you can damage the speakers or
your ears!) Is there signal into the RCA jacks? Use a volt meter or plug
into another piece of equipment to confirm that a signal is present.
-
GREEN INPUT LED does not come on.
Signal IN on the rear RCA inputs can be
increased. (See Operation of Front Controls.)
-
RED INPUT LED comes on.
Signal IN on the rear RCA inputs is too
high; reduce the level from the source. These LEDs should never come on.
(See Operation of Front Controls.)
-
GREEN OUTPUT LED does not come
on. Turn up the channel knobs on the left
side.
-
RED OUTPUT LED comes on.
Turn down the channel knobs on the right
side.

The Amplifier shuts off
unexpectedly. There are two
possibilities that you can fix.
1) Blown circuit breaker: Check to make sure there is power to the amp
from the outlet (the circuit breaker may have blown). The simplest way to
check for power is to unplug the amp and plug in a light. If the light
does not work, the circuit breaker has tripped because there are too many
appliances on the circuit.
2) Thermal shut-down: The left and right channels each have a thermal
protector that will turn the amplifier off if either side gets too hot.
The amplifier is very conservatively designed and can continuously put out
150 watts to each channel indefinitely without getting too hot, even while
sitting in a 100oF room. The only way that the thermal protector can
operate is if a component failed in the amplifier or the amplifier has
been placed in a confined space blocking proper ventilation. If the
amplifier is placed on a shelf, there must be at least 3” clearance on
both sides, the back, and the top. The front of the amplifier should be
near the front of the shelf and the whole front area must be open. To see
whether the thermal protection shut off the amplifier, very briefly - much
less than one second - touch the fins. If you can hold your hand or a
finger for one second comfortably, then it is probably not hot enough to
have tripped the thermal sensors. If it feels very hot, the sensors could
have tripped. In that case, turn off or disconnect the amplifier and wait
fifteen minutes. After the amplifier has cooled, relocate it in a more
open place and try plugging it in and turning it on. If the fins are now
comfortably cool to the touch, and you know that the power is good to the
outlet, and if after pressing the power ON button the red LED does not
come on, then contact your dealer for information on how to obtain help
from qualified service personnel.

Fuses There are six
fuses which can be replaced by qualified service personnel. The circuits
are very conservatively designed. The fuses will not blow in normal
operation. If a fuse has blown, it is probably because another component
which is not user replaceable has failed.
