I2C-bus controlled 4
50 W power amplifier
7.5.1 Start-up diagnostics with DC load detection
If the start-up diagnostics are enabled, the load condition of all four channels is
determined. At the end of the start-up diagnostics cycle, not only the load condition is
known (shorted load, normal load or open load), but also if a separate amplifier is
connected or if the outputs are shorted to battery or ground. If a separate amplifier
(booster) is detected, the amplifier can start-up in line driver mode (low gain setting).
The load diagnostic is insensitive to door-slam (slowly moving speaker due to slamming of
the car door) and to external interference such as crosstalk of relays switching in the
wiring harness; see Figure 10.
