Input Mode Switches:
Two switches are located on the rear panel to control unbalanced signal
grounding and master/slave operation.
"Isolated / Grounded" Switch
The "Isolated / Grounded" 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 IWSv2 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 IWSv2, 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 IWSv2 SUBWOOFER FOR OPTIMUM NOISE PERFORMANCE. CABLE &
SATELLITE BOXES ARE PARTICULARLY TROUBLESOME IN THIS WAY.
"Master / Slave" Switch
The Fathom IWSv2s 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 IWSv2 to centrally control multiple Fathom IWSv2s 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 IWSv2 ships with this switch in the "Master" position. If you are
using a single Fathom IWSv2 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 IWSv2 amplifiers, you
will designate one Fathom IWSv2 as the "Master" and all others in the system as
"Slave" via the "Master/Slave" switch on the rear amplifier panel of each Fathom
IWSv2. LED's on the front panel of the Fathom IWSv2 are provided to indicate
whether the "Master" or "Slave" mode is selected for a given subwoofer.
From the Fathom IWSv2 operating in "Master" mode, the "Output to Slave"
signal carries any signal processing selected on the Master Fathom IWSv2
(including the Master Level setting and D.A.R.O. processing) to further Fathom
IWSv2s 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 IWSv2 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 IWSv2.
