Demo Button

The Demo button triggers a 20 second long tone sequence that briefly demonstrates the sound of the Fathom IWS subwoofer. The Demo function is useful for showcasing the output capability of the Fathom IWS and to verify that the Fathom IWS (or multiple Fathom IWSs) are operational during system troubleshooting.

The Demo button is also used (in combination) to clear (return to flat) the A.R.O. equalizer settings. To clear the A.R.O.’s settings & turn off the Calibrate light, press and hold the Demo button and then press the Defeat button. Please note that you must perform this button sequence quickly. If you hold the Demo button for more than 2 seconds without touching the Defeat button, the Demo tones will start. Should this happen, simply wait for the Demo sequence to end and try again.

Defeat Button

If “Demo” or “Calibrate” is pressed while the defeat function is active, “Defeat” is automatically canceled. No other front panel controls will alter the A.R.O. Defeat state. The Fathom IWS’s Defeat setting is stored in non-volatile memory and will not change even if power is disconnected.

The Defeat button is also used (in combination) to clear (return to flat) the A.R.O. equalizer settings. To clear the A.R.O.’s settings & turn off the Calibrate light, press and hold the Demo button and then press the Defeat button. Please note that you must perform this button sequence quickly. If you hold the Demo button for more than 2 seconds without touching the Defeat button, the Demo tones will start. Should this happen, simply wait for the Demo sequence to end and try again.

Calibrate Button

During the ARO test sequence the Calibrate button’s green LED will blink quickly to alert the user to two special conditions:

1.“JL Audio Microphone NOT Connected”: If you forget to connect the mic before trying to start a Calibration you will get this alert. Press the Calibrate button once to cancel the alert, connect the A.R.O. microphone, and try again.

2.“Inappropriate Sound Level for A.R.O. Calibration”: Since the A.R.O. sequence is completely automatic, this alert likely indicates a problem with the microphone. Press the Calibrate button once to cancel the alert. Ensure that the JL Audio microphone is properly connected and try again. For further help, please refer to Troubleshooting on page 33.

Input Mode Indicators

The Input Mode indicator LEDs show the input mode, either “Master” or “Slave”, selected by the switch on the Fathom IWS’s back panel (unless the “Lights” switch is set to “off”). For further details, see page 20.

Level Mode

The two-position Level Mode switch allows you to select between the following modes:

“Reference” - In this mode, the Master Level control knob has no effect on the Fathom IWS’s output level. Use this setting if you will primarily be controlling the subwoofer level via your receiver or preamplifier/processor. For those of us with small children or overenthusiastic teenagers, this mode of operation will prevent direct manipulation of the Master Level.

“Variable” - In this mode, the Master Level control knob determines the output level of the Fathom IWS subwoofer. This mode is also useful when level matching the Fathom IWS subwoofer to a pair of stereo speakers in a two-channel system.
