SYSTEM CONNECTION DIAGRAM 3:
One Fathom in Mono to
Two-Channel Audio System
When connecting a Fathom (or multiple
Fathoms) 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's input section will sum the
stereo signals to mono.
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 Fathom 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 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 Fathoms
can be connected in "Slave" mode to
the Fathom connected as shown on
this diagram. See "System Connection
Diagram 2" on page 23 for slave
connection explanation.
