SYSTEM CONNECTION DIAGRAM 4:
Two Fathoms in Stereo to
Two-Channel Audio System
When connecting two Fathoms in
stereo to a two-channel audio system you
will only use the “Left or Mono” inputs
of each Fathom. Th
e upper “Input Mode”
switch on each Fathom will be set in the
“Master” position.
We strongly recommend that you
use a high-quality active crossover
to divide your preamplifi er’s signals
prior to connection to the Fathom and
to the amplifi er driving your main
speakers. Th
is will allow you to fi lter 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
preamplifi er’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 Fathoms 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
preamplifi er or active crossover off ers
balanced outputs, we highly recommend
that you use them.
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 (not both).
NOTE: If desired, additional Fathoms
can be connected in “Slave” mode to
each Fathom connected as shown on this
diagram. See “Connection Diagram 2” on
page 23 for slave connection explanation.
