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.

You won't need a computer, spreadsheets or complex measurement equipment, and you won't need to navigate and manipulate complicated interfaces… D.A.R.O. is a fine example of technology in the service of man, if there ever was one.

"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."
