Input Mode Switches:
Two switches are located on the rear panel to control unbalanced signal grounding and master/slave operation.
“Grounded / Isolated” Switch
The “Grounded / Isolated” Input Mode switch affects only the unbalanced RCA inputs and is designed to facilitate a quiet,
The Fathom ships with this switch in the “Isolated” mode. If, with all system components connected and turned on (but no source material playing), you hear a continuous
IMPORTANT: PLEASE NOTE THAT CHANGING ANY COMPONENT IN THE OPTIMIZED SYSTEM (RECEIVER, AMPLIFIER, DVD PLAYER, CABLE OR SATELLITE BOX, ETC.) COULD ALTER THE SIGNAL GROUNDING SCHEME AND CAUSE HUM TO APPEAR IN YOUR PREVIOUSLY QUIET SYSTEM. IF YOU ADD OR CHANGE AN UPSTREAM COMPONENT IN YOUR HOME THEATER SYSTEM, YOU MAY NEED TO REVISIT THIS INPUT MODE SETTING ON THE FATHOM SUBWOOFER FOR OPTIMUM NOISE PERFORMANCE. CABLE & SATELLITE BOXES ARE PARTICULARLY TROUBLESOME IN THIS WAY.
Master / Slave Switch
The Fathoms are designed to easily accommodate the implementation of multiple subwoofers in your home theater system through a master/slave connection chain. This method allows you to utilize the signal processing features of one Fathom to centrally control multiple Fathoms in the room. Master/Slave functionality also makes it possible for the A.R.O. system to optimize the response of a multiple subwoofer installation.
The Fathom ships with this switch in the “Master” position. If you are using a single Fathom you will use the “Master” position and you need not concern yourself with this section any further.
If your installation incorporates two or more Fathoms, you will designate one Fathom as the “Master” and all others in the system as “Slave” subwoofers via the “Master/Slave” switch on the rear amplifier panel of each Fathom. LED’s on the front panel of the Fathom are provided to indicate whether the “Master” or “Slave” mode is selected for a given subwoofer.
From the Fathom operating in “Master” mode, the “Output to Slave” signal carries any signal processing selected on the Master Fathom (including the Master Level setting and A.R.O. processing) to further Fathoms operating in “Slave” mode. “Slave” subwoofer signal processing and level controls will be inoperable. In this mode, the user does not have to worry about level, crossover, and other settings for the slave subwoofers.
Technical Notes:
•Selecting the “Slave” position defeats all
