2 CHANNEL OWNER’S MANUAL

BUILT-IN ELECTRONIC CROSSOVER

2 channel:  18dB per octave electronic crossovers that can be 
configured for full range, high-pass or low-pass application. 

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 the problem. 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.

AUX 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
