AMP 500

Categories :

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;
