Test Conditions and Notes
All tests to be done, unless otherwise specified, from 30Hz to 320Hz at 14.4V DC into 2 ohm loads and adjust
the units gain so that with a .100 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.
the units gain so that with a .100 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.
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 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.

Output Load
Unless otherwise specified, all tests shall be conducted with 2 ohm resistive loads having less than 0.1%
reactive components at any frequency below 1Kz. Each resistor shall have a value that remains within 0.1%
while dissipating the rated output of the unit under test.
