Test Conditions and Notes
x All tests to be done, unless otherwise specified, from 10Hz to 302Hz at 14.4V DC
into 2 ohm loads and adjust the units gain so that with a .250 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.
x 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.
x 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.
x 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 302Hz.
Each resistor shall have a value that remains within 1
% while dissipating the
rated output of the unit under test.
x Power Indicator Green LED steadily illuminates for normal operation. Illuminates
up Red LED blinks when protection circuitry is engaged, and during power up.
