Featuring JL Audio’s exclusive Digital Automatic Room Optimization (D.A.R.O.) system and a proprietary Class-D amplifier design, the Fathom® Sav2 amplifier is purpose-engineered to deliver jaw-dropping output capabilities in almost any home theater or home audio system. With an ultra-powerful design and a complete set of signal processing features, the Fathom® Sav2 amplifier efficiently generates up to 2,000 watts of continuous power to drive a custom subwoofer system.
The Fathom® SAv2 amplifier includes the following features:
- Pristine, stereo audio circuit pathways used throughout
- Built-in, optimized equalizer curves for use with JL Audio subwoofers systems
- Fixed or variable level control options
- D.A.R.O. (Digital Automatic Room Optimization) - fully automated 18-band digital equalization system measures and corrects in-room response to optimize low frequency performance with a single touch (includes laboratory-grade calibration microphone)
- Active low-pass filter (30 Hz to 130 Hz) with selectable modes (Off, 12 dB or 24 dB per octave)
- Variable phase control from 0 to 280 degrees, referenced at 80 Hz
- Selectable polarity control (0 or 180 degrees) to optimize subwoofer integration
- 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
- Grounded or isolated input mode options for quiet, noise-free performance
- Selectable master or slave input mode to easily implement multiple subwoofers, allowing central control and signal processing of additional Fathom® SAv2 amplifiers in a system
- Choice or balanced (XLR) or unbalanced (RCA) input connections (stereo or mono)
- Automatic turn-on options via signal sensing or 12V trigger; includes 12V output trigger to control additional amplifiers or components
- Versatile mounting options for table-top setups or rack-mount installations

Digital Automatic Room Optimization (D.A.R.O.)
Summary:
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.
Detailed Information:
In typical listening spaces, subwoofer and listener placement have a profound effect on the accuracy of low-frequency reproduction. While we always recommend that you place your subwoofers in good-sounding locations, we know that these often can be impractical locations. In the real world, subwoofer placement almost always involves a compromise between sonic performance, practicality and aesthetics.
To face this dilemma head on, JL Audio subwoofer systems incorporate a clever piece of technology called Digital Automatic Room Optimization (D.A.R.O.). The D.A.R.O. system self-generates a series of calibration tones, measures the frequency response at the listening position, and automatically configures an 18-band, 1/6 octave equalizer for a flat end-result. The system effectively allows for smooth, well-balanced sub-bass from a variety of locations that would have been less than ideal without D.A.R.O.
To perform this audio magic, all you have to do is:
- Connect the included calibration microphone to the front panel of the subwoofer.
- Press the calibrate button on the front panel of the subwoofer.
- Hold the microphone at the primary listening position for about a minute.
- A few minutes later, you have completed this one-time setup routine.

"If you want uncompromised bass performance in a room that won't easily accommodate freestanding subwoofers, there's only one game in town."

"It's a sub that makes no acoustic compromises, nor does it force you to make the lifestyle compromises that a typical in-room sub would. in some ways, it's a shame that all the cool technology here is hidden from view-but, when you think about it, not seeing anything of this system is the coolest part of all. If you've got the money, and you've got a wall, this sub's for you."
