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

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

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

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
