• HD 600W 4-channel full range Class D amplifier.

Features:

• 4-channel full-range Class D amplifier, 150W x 4 @ 1.5-4 Ω.
  
• This compact multi-channel powerhouse uses JL's single-cycle control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion low and maximizes sound quality.
  
• When using the HD750/1 or HD1200/1 to drive a subwoofer system, the HD600/4 is the ideal satellite amplifier, delivering tremendous dynamics with pristine resolution.
  
• It can also be used alone as a very powerful 3-channel system amplifier with 150 W x 2 for the satellites and 300 W x 1 for a subwoofer system.
  
• 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.
