A Few Precautions
Please read this manual carefully. In addition to basic installation and
operating instructions, it provides valuable information on various
RB-1592 system configurations as well as general information that
will help you get optimum performance from your system. Please
contact your authorized Rotel dealer for answers to any questions you
might have. In addition, all of us at Rotel welcome your questions and
comments
Save the RB-1592 shipping carton and all enclosed packing material
for future use. Shipping or moving the RB-1592 in anything other than
the original packing material may result in severe damage to your
amplifier.
Fill out and send in the owner’s registration card packed with the
RB-1592. Also be sure to keep the original sales receipt. It is your
best record of the date of purchase, which you will need in the event
warranty service is ever required.
Placement
Place the RB-1592 on a solid, level surface away from sunlight, heat,
moisture, or vibration.
Don’t stack other components or objects on top of the RB-1592. Don’t
let any liquid fall into the unit.
Likewise, remember the weight of the amplifier when you select an
installation location. Make sure that the shelf or cabinet can support its
weight.
The RB-1592 generates heat during normal operation. Do not block
ventilation openings. Allow a minimum of 10 cm or 4 inches of
unobstructed space around the unit. If installed in a cabinet, make sure
that there is adequate ventilation.
AC Power and Control
AC Power Input
7
Your RB-1592 is configured at the factory for the proper AC line
voltage in the country where you purchased it (USA: 120 volts/60
Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted
on a label on the side panel. The RB-1592 must be connected to a
polarized 3-pin wall outlet.
The RB-1592 is supplied with the proper AC power cord. Use only this
cord or an exact equivalent. Do not modify the supplied cord. Do not
use an extension cord.
Be sure the power switch on the front panel of the RB-1592 is turned
off. Then, plug one end of the cord into the AC power connector on
the back panel of the amplifier. Plug the other end into an appropriate
AC outlet.
If you are going to be away from home for an extended period of
time, it is a sensible precaution to unplug your amplifier.
Power Switch and Indicator Light
1
The power switch is located on the left side of the front panel. To turn
the amplifier ON (or to activate the 12V trigger), push the switch in.
The indicator light around 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 position.
Protection Indicator
2
A thermal protection circuit protects the amplifier against potential
damage in the event of extreme or faulty operating conditions. Unlike
many designs, the RB-1592’s protection circuit is independent 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 temperatures exceed safe limits.
In addition, the RB-1592 includes overcurrent protection which
operates only when load impedance drops too low.
Should a faulty condition arise, the amplifier will stop playing and the
PROTECTION LED on the front panel will light. If this happens, turn
the amplifier off, let it cool down for several minutes, and attempt to
identify and correct the problem. When you turn the amplifier back on,
the protection circuit will automatically reset and the PROTECTION LED
should go out.
In most cases, the protection circuitry activates because of a fault
condition such as shorted speaker wires, or inadequate ventilation
causing an overheating condition. In very rare cases, highly reactive
or extremely low impedance speaker loads could cause the protection
circuit to engage.
12V Trigger On/Off Mode Selector
8
The RB-1592 provides different options for manual or automatic power
on/off operation. These modes are selectable using a two position flip
switch on the back panel as follows:
With the 12V Trigger switch in the OFF position,
•
the
amplifier is turned on or off manually using the front panel power
switch. Also use this mode if you are using a switched AC outlet
to control power to the amplifier.
With the 12V Trigger switch in the ON position,
•
the
amplifier is turned on automatically when a 12 volt trigger signal
is present at the 12V TRIG input to the right of the switch. The
amplifier goes into standby mode if the +12 volt signal is not
present. The front panel POWER SWITCH overrides this function.
It must be ON for the +12V trigger to work. Turning the switch
