SYSTEM CONNECTION DIAGRAM 2:
Multiple Fathom IWSs to
Home Theater Receiver or
Home Theater Preamp/Processor
To greatly simplify using multiple
subwoofers in a single home theater
system, Fathom IWSs incorporate a
"Master/Slave" signal distribution system.
This allows control of all the Fathom IWSs
in a system from a single "Master" unit.
First, you will select one of the Fathom
IWS subwoofers as the "Master" via its
upper "Input Mode" switch. Generally,
you will designate the Fathom IWS closest
to the receiver/preamp as the master. In
some cases; for example, when the control
panel of certain units is difficult to access,
you may prefer to designate the one which
is easiest to access as the master.
Two connection types are available
for connecting the master Fathom IWS
to your home theater system: balanced
(XLR or 1/4-inch TRS connector) and
unbalanced (RCA-type connector).
Balanced connections provide superior
noise rejection and ensure proper
grounding between components. If
your receiver or processor has balanced
outputs, we highly recommend that you
use them to connect to the Fathom IWS
designated as the master.
In the connection diagram at right,
balanced connections are shown as solid
lines, unbalanced connections are shown
dotted. You will only use one of these
input connection methods for the Fathom
IWS designated as the master (not both).
The remaining Fathom IWSs in the
system will be configured as "Slave" units
via their "Input Mode" switches. Using
balanced XLR cables, you will connect
the master Fathom IWS's "Output to
Slave" to the "Left or Mono" balanced
input of the first slave Fathom IWS. That
slave unit's "Output to Slave" connector
will feed the "Left or Mono" input of
the next slave unit via another balanced
XLR cable. Subsequent slave units will
be connected in the same manner.
IMPORTANT
Connections between the "Master"
and "Slave" Fathom IWSs and
between "Slave" Fathom IWSs are
via balanced XLR cables ONLY.
