Power Amplifier
2-Channel Operation
Advanced MOSFET Oversized Floating Rail Power Supply
Floating Ground Factory - Head - Unit Speaker - Level input
Variable Input Sensitivity (250mV - 6V)
Fully Complementary Output Stage with Class-D Voltage Amplification
Gold-plated Power, Input and Output Connectors
1-Ohm Stable ( 2 ohm Prallel MODE )
All tests to be done, unless otherwise specified, from 10Hz to 320Hz at 14.4V DC into 2 ohm loads and ad
the units gain so that with a .775 volt input signal the unit is at its maximum rated output. All measur
will be done using an Audio precision system one and the supply voltage.
An A+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless other
specified. The voltage applied to the unit shall be measured at the power connection on the Amplifier.
Signal Source
Unless otherwise specified, all tests shall be conducted with the Audio Signal Generator output configur
be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shall
connected to the Amplifier PWR GND at the Amplifier.
Output Load
Unless otherwise specified, all tests shall be conducted with 2 ohm resistive loads having less than 10%
reactive components at any frequency below 350Hz. Each resistor shall have a value that remains within 1
while dissipating the rated output of the unit under test.
Power Indicator LED steadily illuminates for normal operation. LED blinks when
protection circuitry is engaged, and during power up.
