JL Audio HD600/4

Discover the 4-channel amplifier HD600/4 from JL Audio. With its Class D technology, this amplifier is available as 150W x 4-channel or 300W x 2-channel and is characterized by its compact dimensions. The combination of single-cycle control switching design and RIPS technology gives the HD600/4 high dynamics and clear resolution. It can be used as a standalone 3-channel system amplifier or in combination with the HD750/1 or HD1200/1 models for subwoofer systems. Another highlight of this robust amplifier is its brushed aluminum finish with black powder-coated heat sinks.

• 4-channel full-range amplifier Class D, 150 W x 4 @ 1.5-4 Ω
  
• This compact multi-channel powerhouse uses JL's single-cycle control switching design and RIPS technology to deliver 150W x 4 or 300W 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 heatsinks and base plate. A black powder coated sealed cover is also included to protect the controls.
