Features; Test Conditions And Notes - JBL BP150.1 Service Manual

BP-150.1
1-Channel Operation
Advanced MOSFET Oversized Floating Rail Power Supply
Floating Ground Factory - Head - Unit Speaker - Level input
Variable Input Sensitivity (250mV - 4V)
Fully Complementary Output Stage with Class-D
Gold-plated Power, Input and Output Connectors
1-Ohm Stable
All tests to be done, unless otherwise specified, from 10Hz to 320Hz at 14.4V DC into 4 ohm loads and
the units gain so that with a .775 volt input signal the unit is at i's maximum rated output. All meas
will be done using an Audio precision system one and the supply voltage.
An B+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless oth
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 config
be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shal
connected to the Amplifier PWR GND at the Amplifier.
Output Load
Unless otherwise specified, all tests shall be conducted with 4 ohm resistive loads having less than 1
reactive components at any frequency below 350KHz. Each resistor shall have a value that remains withi
while dissipating the rated output of the unit under test.
Power Indicator Green LED steadily illuminates for normal operation. Illuminates up Red LED blinks whe
protection circuitry is engaged, and during power up.
