Amplifier
4 Ohms Stereo => 35W x 4
2 Ohms Stereo => 50W x 4
4 Ohms Bridged => 100W x 2
Fuse Type => 30 Amp ATC
DC Operating Range => 9V – 18V
Fuse Type => 30 Amp ATC
DC Operating Range => 9V – 18V
All tests to be done, unless otherwise specified, from 20KHz to
20KHz at 14.4V DC into 4 ohm loads and adjust the units gain so that with a
.775 volt input signal the unit is at its maximum rated output. All
measurements 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 otherwise specified. The voltage applied
to the unit shall be measured at the power connection on the Amplifier.
Unless otherwise specified, all tests shall be conducted with
the Audio Signal Generator output configured to be balanced, less than or equal
to 50 ohm source impedance, and floating. The signal source "GND"
shall be connected to the Amplifier PWR GND at the Amplifier.
Unless otherwise specified, all tests shall be conducted with 4
ohm resistive loads having less than 10% reactive components at any frequency
below 75KHz. 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.
