RSd AMPLIFIERS

MONOBLOCK OWNER’S MANUAL

BUILT-IN ELECTRONIC CROSSOVER
18dB per octave electronic crossover for low-pass and an
18dB per octave subsonic ﬁlter.

ON BOARD PROTECTION
The on-board protection circuitry monitors abnormal
conditions such as voltage spikes, short circuit and over
thermal limits. When any of these conditions exist, the
protection circuit will shut down the ampliﬁer and light up the
protection indicator to identify that a problem exists. Once
the problem is resolved, the ampliﬁer will return to normal
operation automatically.

HIGH SPEED HIGH CURRENT MOSFET SWITCHING
POWER SUPPLY
High current MOSFET transistors are used in the power
supply section to minimize internal heat and maximize
reliability.

HIGH CURRENT/HIGH VOLTAGE FULLY
COMPLEMENTARY OUTPUT STAGE
Complementary output stage audio circuitry has been a
standard in high end home ampliﬁer design. Phoenix Gold is
one of the very few car audio manufacturers to incorporate
this design approach into a mobile audio ampliﬁer.

LINE OUTPUTS
The ampliﬁers full-range line outputs can be used to feed
signals to another ampliﬁer for future expansion or for setting
up a more sophisticated system.

WIDE RANGE INPUT SENSITIVITY ADJUSTMENT
The input sensitivity level of this ampliﬁer can be easily varied
from as low as 200 mV to as high as 8.0 volts by adjusting the
control on the Input Panel.

MULTI-FUNCTION PROTECTION INDICATOR
When the red protect indicator lights up it signiﬁes a high
operating temperature is detected and the ampliﬁer is
temporarily shut down to allow for a cooling period. As soon
as the temperature returns to a safe level, the ampliﬁer will
restart and resume normal operation. This indicator also lights
up when the ampliﬁer detects either an over-current situation,
shorted speaker outputs or a DC offset at the outputs.
Turn off the ampliﬁer; double-check all inputs and speaker
connections to make sure there is no short or inappropriate
input. If all connections are in order, turn on the ampliﬁer to
resume operation.

VARIABLE BASS BOOST
The bass boost will increase the output centered at 45Hz from
0 to 18dB
