Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 1-800-123-4567 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Subwoofer Amplifier/Processor, 600W

JL Audio FATHOMRSA600W

 

Subwoofer Amplifier/Processor with rack mount option and JLink™ Connectivity

Equipped with flexible features and a robust power amplifier section, the Fathom® SA-600W is an ideal choice to drive a custom subwoofer system in home theater and home audio systems. The full set of Fathom® signal processing features is included, along with additional DSP features, managed through an intuitively designed onboard interface. With its precisely engineered switching power supply and proprietary Class-D amplifier topology, the SA-600W is capable of efficiently delivering up to 600 watts of continuous power.

The SA-600W includes the following features:

  • Pristine, stereo audio circuit pathways used throughout
  • Intuitive interface with LCD display provides detailed control of on-board settings and functions
  • On-board, 2-way active crossover (12/24 dB per octave), capable of supporting a stereo system with a low-pass filtered subwoofer output and high-pass filtered line outputs to feed the main speakers' amplifier
  • Built-in, optimized equalizer curves for use with JL Audio subwoofers systems
  • Fixed or variable level control options
  • Selectable polarity control (0 or 180 degrees) to optimize subwoofer integration
  • Programmable delay controls for the SA-600W's subwoofer outputs and line outputs.
  • E.L.F. (Extreme Low Frequency) trim applies equalizer cut or boost at 25 Hz (-12 to + 3 dB) to tailor a subwoofer's response for a particular room.
  • D.A.R.O. (Digital Automatic Room Optimization) automatically measures and corrects in-room response to optimize low frequency performance (requires optional JL Audio calibration microphone - CAL-MIC1 - sold separately)
  • Three band parametric equalizer with configurable center frequency, Q and gain, to further optimize subwoofer system response
  • Grounded or Isolated input mode options for quiet, noise-free performance
  • Stereo, high-level inputs accept direct connection from amplified receiver outputs when no line level signal is available.
  • Wireless signal connectivity is available via the optional JLink™ Transmitter/Receiver system ( JLink™ TRX - sold separately).
  • Automatic turn-on options via signal sensing or 12V trigger. 12V input and output triggers to control additional SA-600Ws or peripheral equipment
  • Front-mounted USB port and DFU button provides easy access to update firmware.
  • Versatile mounting options for table-top setups or rack-mount installations.


Technology

Digital Automatic Room Optimization (D.A.R.O.)

JL Audio's exclusive D.A.R.O. technology uses a powerful on-board DSP to automatically optimize the subwoofer's in-room frequency response. This leads to a superb listening experience, no matter where the subwoofer is placed.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
