AC Power and Control

AC Power Input

Because of its high power rating, the RB-1050
can draw considerable current. Therefore, it
should be plugged directly into a 2-pin po-
larized wall outlet. Do not use an extension
cord. A heavy duty multi-tap power outlet strip
may be used if it (and the wall outlet) is rated
to handle the current demanded by the
RB-1050 and all the other components con-
nected to it.

Be sure the Power Switch on the front panel
of the RB-1050 is turned off (in the out posi-
tion). Then, connect the supplied power cord
to the Power Connector

on the back panel

of the amplifier and to the AC power outlet.

Your RB-1050 is configured at the factory for
the proper AC line voltage in the country where
you purchased it (either 115 volts AC or 230
volts AC with a line frequency of either 50
Hz or 60 Hz). The AC line configuration is
noted on a decal on the back panel.

Note:

Should you move your RB-1050

amplifier to another country, it is possible
to reconfigure your amplifier for use on a
different line voltage. Do not attempt to
perform this conversion yourself. Opening
the enclosure of the RB-1050 exposes you
to dangerous voltages. Consult a qualified
service person or the Rotel factory service
department for information.

If you are going to be away from home for
an extended period of time such as a month-
long vacation, it is a sensible precaution to
unplug your amplifier (as well as other au-
dio and video components) while you are
away.

Power Switch

and Power

Indicator

The power switch is located on the front panel
of your amplifier. To turn the amplifier on, push
the switch in. The LED indicator above the
switch will light, indicating that the amplifier
is turned on. To turn the amplifier off, push
the button again and return it to the out po-
sition.

12V Trigger Mode Selector

The Amplifier provides the option for manual
or automatic power on/off operation. These
modes are selectable using a switch on the
back panel.

NOTE:

The front panel Power Switch

must be ON for the automatic turn on sys-
tem to work.

When the switch is in the “12V TRIG” posi-
tion, the amplifier is turned on automatically
when a 12V trigger signal is present at the
3.5 mm Jack of TRIGGER IN on the rear panel.
The amplifier will go into standby mode af-
ter a delay of 5 minutes if the +12V signal is
not present.

When the switch is in the “SIGNAL SENSE”
position the amplfier is turned on whenever
an audio signal is applied to the Inputs

If no audio signal is applied to the inputs the
amplifier will return to standby mode after a
delay of 5 minutes.

When the switch is in the “OFF” position the
automatic activation system is turned off. Only
the front panel Power Switch will control the
amplifier.

12V Trigger Input
and Output

The jack labeled IN is for connecting the
3.5mm Plug/Cable carrying a +12 volt trig-
ger signal to turn the amplifier on and off.
To use this feature the front panel Power Switch
must be set to the ON position. This input ac-
cepts any control signal (AC or DC) ranging
from 3 volts to 30 volts.

The jack labeled OUT is for connecting an-
other 3.5mm plug/cable to provide a 12V
trigger signal to other components. The 12V
output signal is available whenever a +12 volt
trigger signal is applied to the IN connector.

Circuit Breaker

A circuit breaker on the rear panel protects
the amplifier’s electrical circuity. Generally, the
circuit breaker will only open under a fault
condition which results in excessive current
draw. To reset the circuit breaker, press the
button. Should it repeatedly open, contact your
authorized Rotel dealer for troubleshooting
assistance.

Protection Circuitry

The RB-1050 features a thermal protection cir-
cuit that protects the amplifier against potential
damage in the event of extreme or faulty
operating conditions. Unlike many designs,
the RB-1050’s protection circuit is indepen-
dent of the audio signal and has no impact
on sonic performance. Instead, the protection
circuit monitors the temperature of the output
devices and shuts down the amplifier if tem-
peratures exceed safe limits.

Most likely, you will never see this protection
circuitry in action. However, should a faulty
condition arise, the amplifier will stop play-
ing and the LED indicator on the front panel
will light up.

If this happens, turn the amplifier off, let it cool
down for several minutes, and attempt to iden-
tify and correct the problem that caused the
protection circuitry to engage. When you turn
the amplifier 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 im-
pedance speaker loads could cause the pro-
tection 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.

Clipping Indicators

Each channel has a Clipping Indicator on the
front panel. “Clippping” occurs when an am-
plifier it driven to the point it begins to pro-
duce distortion. The term refers to the flattening
or “clipping” of the musical waveform that
occurs when an amplifier is driven beyond
its rated power. If the Clipping Indicators light,
reduce the volume level of the system. Fail-
ure to so do could result in damage to the
speakers connected to the amplifier. It may
also cause the Protection Circuit to activate.
