• HD 900W 5 Channel Class D System Amplifier

Features:

• Class D 5-channel system amplifier, 100W x 4 + 500W x 1.
  
• The HD900/5's ability to function as a "one-box solution" makes it ideal for installations where space is at a premium and sound quality is the primary objective.
• Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very powerful 500 W to its subwoofer channel.
• R.I.P.S. allows high power to be delivered over a wide range of load impedances, while tight power supply regulation keeps distortion low and maximizes sound quality.
• This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and base plate.
• A black powder coated sealed cover is also provided to protect the controls.
