Power
Supply:
PFC
power supply design with ripple elimination network;
Low
surge limit reduces AC surge current, eliminating the need for an additional
expensive power sequencer.
Comprehensive
Protection Circuits:
AC
Protection: Automatically shuts down the power supply when AC voltage exceeds
the operating range;
Clipping
limiter: Limits severely clipped waveforms from reaching the speaker while
maintaining peak power output;
DC
Protection: Prevents the occurrence of subsonic signals at the output terminal;
Ultra-high
frequency protection: Prevents strongly non-musical high-frequency signals that
are inaudible from reaching the speaker;
Short circuit protection: Automatic protection reset function to prevent amplifier short circuits and other circuit stress faults.
Digital
Signal Processing:
ADI
SHARC 21489 platform architecture;
AD/DA
Converters: 24-bit @ 48 kHz;
Provides
algorithms for parametric equalization, feedback suppression, echo
cancellation, noise suppression, automatic gain, automatic mixing, etc.;
Adjustable
delay of up to 1200ms for time alignment;
Active
damping control for real-time monitoring of the speakers.
Non-traditional
digital power amplifier;
Built-in
digital signal processing;
2
x 500W @ 8Ω, fanless design;
Overall
efficiency @ 90% (Max);
Real-time
monitoring of the damping on the speakers;
