  Seismic™ Series
 
  Seismic™ Ultra-Class-D™ Amplifier
  Super-Efficient Switching Amplifier  
  Over 90% efficiency, provides output of 4500 watts Dynamic Peak / 1500 watts RMS Sustained.  
  Novel Adaptive PWM (Pulse Width Modulation) Power Processor  
  Novel Adaptive PWM (Pulse Width Modulation) Power Processor minimizes distortion and optimizes efficiency. Conventional Class-D designs have very low power supply rejection. Our Ultra-Class-D™ design inherently rejects power supply variations.  
  No Power Transformer  
  The output stage is Direct-Connected™ to the power line to provide maximum power.  
  Opto-Coupled Inputs  
  Opto-Coupled Inputs offer better isolation and lower noise.  
  Advanced Output Stage  
  Advanced Output Stage increases switching speed and efficiency. Unlike conventional Class-D designs, which use the slow built-in diodes of the output MOSFETs, our Ultra-Class-D™ design steers circulating currents to ultra-fast diodes (ten times faster).  
  Proprietary Voice Coil Temperature Sensor  
  Should the voice coil overheat, the amplifier output is reduced until the voice coil cools down.  
  Amplifier Temperature Sensor  
  Amplifier Temperature Sensor maintains safe operating temperatures even under extreme conditions.  
  Short Circuit Protection  
  Short Circuit Protection reacts within 10 microseconds.
