ROTEL RA-06 - Manual (Page 9)

12 Volt Trigger Outlet
\
Some audio components can be turned on auto-
matically when they receive a 12V turn on “signal”.
The 12V Trigger Outputs of the RA-06 provide the
required signal. Connect compatible components
to the RA-06 with a conventional 3.5mm miniplug
cable. When the RA-06 is in Standby mode, the
trigger signal is interupted, so the components
controlled by it are turned off.
Protection Indicator
3
The RA-04 has both thermal and over-current
protection circuitry that protects the amplifi er
against damage in the event of extreme or faulty
operating conditions. The protection circuits
are independent of the audio signal and have
no impact on sonic performance. Instead, the
protection circuits monitor the temperature of
the output devices and shut down the amplifi er
if temperatures exceed safe limits.
Most likely, you will never see this protection cir-
cuitry in action. However, should a faulty condition
arise, the amplifi er will stop playing and the LED
indicator on the front panel will light up.
If this happens, turn the amplifi er off. Let it cool
down for several minutes, and attempt to identify
and correct the problem that caused the protection
circuitry to engage. When you turn the amplifi er
back on, the protection circuit will automatically
reset and the indicator LED should go out.
In most cases, the protection circuitry activates
because of a fault condition such as shorted
speaker wires, or inadequate ventilation lead-
ing to an overheating condition. In very rare
cases, highly reactive or extremely low imped-
ance speaker loads could cause the protection
circuit to engage.
If the protection circuitry triggers repeatedly
and you are unable to isolate and correct the
faulty condition, contact your authorized Rotel
dealer for assistance in troubleshooting.
Troubleshooting
Most diffi culties in audio systems are the result
of incorrect 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 RA-06 refer to the suggestions
for the following conditions:
Power Indicator Is Not Lit
The Power Indicator should be lit whenever the
RA-06 is plugged into the wall power outlet
and the Power Switch is pushed in. If it does
not light, test the power outlet with another
electrical device, such as a lamp. Be sure the
power outlet being used is not controlled by
a switch that has been turned off.
Fuse Replacement
If another electrical device works when plugged
into the power outlet, but the Power Indicator
of theRA-06 does not light when plugged into
the same outlet and the Power Switch is pushed
in, it indicates that the internal power fuse may
have blown. If you believe this has happened,
contact your authorized Rotel dealer to get the
fuse replaced.
No Sound
Check the signal source to see if it is function-
ing properly. Make sure the cables from the
signal source to the RA-06 inputs are connected
properly. Be sure the Listening Selector is set
to the proper input. Check the wiring between
the RA-06 and the speakers.
