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 “Connection Diagram 2” on
page 23 for slave connection explanation.
WARNING! TURN OFF THE FATHOM AND ALL OTHER EQUIPMENT IN THE
SYSTEM BEFORE MAKING OR CHANGING ANY CONNECTIONS!
