Power Switch and Power Indicator

The power switch is located on the front panel of your amplifi er. To
turn the amplifi er on, push the switch in. The ring around the switch
button will light, indicating that the amplifi er is turned on. To turn the
amplifi er off, push the button again and return it to the out position.

Protection Indicator

2
Thermal and protection circuits protect the amplifi er against potential
damage in the event of extreme or faulty operating conditions. Unlike
many designs, the RB-1510 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 amplifi er if safe limits are exceeded.
In addition, the RB-1510 includes over-current protection which
operates only when load impedances drop too low. This protection
is independent for each channel and is indicated by the front panel
Protection LED.
Should a faulty condition arise, the amplifi er channel at fault will stop
playing and the Protection LED on the front panel will light.
If this happens, turn the amplifi er off, let it cool down for several
minutes, and attempt to identify and correct the problem. When you
turn the amplifi er 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
leading to an overheating condition. In very rare cases, highly reactive
or extremely low impedance speaker loads could cause the protection
circuit to engage.
Note: The Protection Mode LED also lights when the 12V Trigger
system is being used and the amplifier is in Standby mode.

Auto Turn On/Off Mode Selector

The amplifi er provides three options for manual or automatic power
on/off operation. These modes are selectable using a switch on the
back panel.
• With the switch in the OFF position, the amplifier is turned on or off
manually using the front panel power switch. Use this mode if you
are using a switched AC outlet to control power to the amplifier.
• With the switch in the SIGNAL SENSING position, the amplifier
turns on automatically when a signal is sensed at the inputs. The
amplifier will go into standby mode with no signal. The front panel
power switch must be ON for the signal sensing to work. Turning
the switch OFF cuts power to the amplifier, regardless of whether
or not a signal is present.

• With the switch in the 12V TRIG. position, the amplifier is turned
on automatically when a 12 volt trigger signal is applied to the
3.5mm jack to the left of the switch. The amplifier will go into
standby mode with no signal if the +12 volt signal is not present.
The front panel POWER SWITCH must be ON for the +12V
trigger to work. Turning the switch OFF cuts power to the amplifier,
regardless of whether or not a trigger signal is present.

12V Trigger Input and Output

The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying
a +12 volt trigger signal to turn the amplifi er on and off. To use
this feature the front panel Power Switch
position. This input accepts any control signal (AC or DC) ranging
from 3 volts to 30 volts.
The jack labeled OUT is for connecting another 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.

Input Signal Connections

See Figure 2
The RB-1510 has conventional RCA type input connectors, the type
found on nearly all audio equipment.
Note: To prevent loud potentially damaging noises, make sure the
amplifier is turned off when you make any changes to the input
signal configuration.
Select high quality audio interconnect cables. Connect each of the
outputs from the preamplifi er or signal processor to the corresponding
5
input of the RB-1510 .

Input Mono Switch

4
In certain custom confi gurations you may want both channels of the
RB-1510 to output the same signal. In such systems set the Input Mono
switch to "On". Use the Left channel input. That input signal will be
output from both channels.

Front Panel Level Controls

3
The Level controls on the front panel let you control the output volume
of the RB-1510. In most systems these controls should be turned up
all the way (full clockwise position). In some situations, such as when
the amplifi er is part of a multi-room or bi-amplifi ed speaker system, it
may be necessary to reduce the output level. Turn the controls down
(counterclockwise) as needed.
Turning down the level does not reduce the maximum output of the
amplifi er. It simply increases the input signal required to achieve
maximum output power.
