RECOMMENDED SETUP PROCEDURES (continued)

Subwoofer System Setup:

Once you have set the controls on your home theater receiver or preamp/ processor and on your Fathom IWS(s) to the settings recommended on pages 24-25, you are ready to begin setting up your Fathom IWS for optimum performance.

In some systems, the Fathom IWS amplifier will be installed away from the listening environment. For these cases, the ARO microphone cable will not be long enough to perform the Calibration.

To facilitate Calibration with the Fathom IWS amplifier in the listening room, the Fathom IWS subwoofer enclosure includes front-mounted speaker terminals (standard banana jacks - see figure). These terminals will allow the user to temporarily connect the amplifier to the enclosure for Calibration, even after the enclosure is permanently installed in the wall cavity.

If your system has a Master / Slave configuration, you only need to have the amplifier designated as Master located in the listening room. You must run a temporary XLR cable to the remotely located Slave unit(s).

1) Applying Automatic Room Optimization (A.R.O.)

You are now ready to apply the power of JL Audio’s exclusive Automatic Room Optimization system. This system will measure the response of the subwoofer at your primary listening seat and apply a powerful equalizer to tame the peaks caused by room modes, resulting in smoother, more accurate bass performance. If you are using multiple Fathom IWSs in a master/slave configuration, you will only need to address the unit designated as “Master” to perform A.R.O. calibration for the entire subwoofer system. Note that all front-panel signal processing is defeated during A.R.O. calibration, regardless of the knob settings. Normal operation is restored once calibration is complete.

a)Set the Main Power switch to the “ON” position and be sure the Fathom IWS’s indicator lights are switched “ON” via the “Lights” switch.

b)Remove the calibration microphone from its protective pouch and connect its cable to the mini-XLR jack on the Fathom IWS’s front control panel.

NOTE: A.R.O. Calibration is only possible when the included JL Audio test microphone is plugged in to the Fathom IWS front panel. The “Calibrate” feature is disabled with no microphone plugged in to prevent accidental loss of settings.

c)Connect the microphone to the other end of the mic cable and temporarily place the mic in the primary listening seat. If you have a microphone stand, you can place the microphone at head height and position in the primary listening seat.

d)On the Fathom IWS’s control panel, press the “Calibrate” button. The green light on the “Calibrate” button will flash slowly, indicating that calibration will begin in 5 seconds.
