SYSTEM CONNECTION DIAGRAM 3:
One Fathom IWS in Mono to
Two-Channel Audio System
When connecting a Fathom IWS (or
multiple Fathom IWSs) in mono to a two-
channel audio system you will use both
the "Left or Mono" and the "Right" inputs.
Summing circuitry in the Fathom IWS's
input section will sum the stereo signals
to mono.
We strongly recommend that you
use a high-quality active crossover to
divide your preamplifier's signals prior
to connection to the Fathom IWS and
to the amplifier driving your main
speakers. This will allow you to filter low
frequencies out of the signals driving
the main speakers, resulting in better
performance.
If you are not using an active crossover
and are comfortable running your main
speakers full-range, you can split your
preamplifier's output signals using
appropriate Y-connectors in place of the
active crossover shown in the diagram.
Two connection types are available
for connecting the Fathom IWS to your
two-channel audio 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
preamplifier or active crossover offers
balanced outputs, we highly recommend
that you use them.
In the connection diagram at left,
balanced connections are shown as solid
lines, unbalanced connections are shown
dotted. You will only use one of these
input connection methods (not both).
NOTE: If desired, additional Fathom
IWSs can be connected in "Slave" mode to
the Fathom IWS connected as shown on
this diagram. See "Connection Diagram
2" on page 23 for slave connection
explanation.
