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, hum-free connection to your
audio or home theater system. This feature is included to deal with the signal
grounding issues often encountered in home theater systems when several
components from different manufacturers are interconnected.
The Fathom v2 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 low-frequency hum through your Fathom v2, flip this switch to the
"Grounded" position and evaluate the difference in the noise level. Use whichever
switch position provides the least hum or noise.
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
V2 SUBWOOFER FOR OPTIMUM NOISE PERFORMANCE. CABLE & SATELLITE
BOXES ARE PARTICULARLY TROUBLESOME IN THIS WAY.
Master / Slave Switch
The Fathom v2s 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 v2 to centrally control multiple Fathom v2s in the room.
Master/Slave functionality also makes it possible for the D.A.R.O. system to
optimize the response of a multiple subwoofer installation.
The Fathom v2 ships with this switch in the "Master" position. If you are using
a single Fathom v2 you will use the "Master" position and you need not concern
yourself with this section any further.
If your installation incorporates two or more Fathom v2s, you will designate
one Fathom v2 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 v2.
LED's on the front panel of the Fathom v2 are provided to indicate whether the
"Master" or "Slave" mode is selected for a given subwoofer.
From the Fathom v2 operating in "Master" mode, the "Output to Slave" signal
carries any signal processing selected on the Master Fathom v2 (including the
Master Level setting and D.A.R.O. processing) to further Fathom v2s 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 user-definable signal processing and
the master level control. Because of this, there are some special situations
in which you may want to operate a single Fathom v2 in "Slave" mode. If
you are utilizing outboard signal processing and level-matching controls,
activating the "Slave" mode will prevent anyone from affecting system
parameters with the manual controls on the Fathom v2.
