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 preamplifier’s signals prior to connection to the Fathom 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 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 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.
