IMPORTANT

Unbalanced Inputs

The Fathom subwoofer features individual left and right unbalanced RCA- type input connectors. These are the most commonly used connectors for home audio applications and must be used if your receiver or preamplifier/processor does not provide balanced outputs. While unbalanced connections are not as noise-immune as a balanced connection, Fathom subwoofers employ optical isolation on the unbalanced inputs to minimize the possibility of noise in your system.

For systems with a mono subwoofer or “LFE” channel connection, only the RCA-type jack labeled “Left or Mono” will be used. This applies to most modern multi-channel receivers and preamplifier / processors. Separate left and right RCA-type input jacks are provided for systems without a dedicated mono subwoofer connection. This typically applies to two-channel audio equipment.

Technical Notes:

When balanced outputs are not available on the signal source, you must use the RCA-type unbalanced inputs. Fathoms feature optical isolation circuitry on the unbalanced inputs to minimize the likelihood of ground loop induced noise. Unbalanced input impedance is 10 kohms.

Connections are industry-standard for unbalanced signal cables as follows:

RCA-type connection: Tip: Positive

Sleeve: Negative

IMPORTANT: IF NOISE EXISTS AFTER CONNECTION, FATHOMS ALLOW FOR GROUNDING OR ISOLATION OF THE UNBALANCED INPUTS. PLEASE REFER TO THE “INPUT MODE SWITCHES” SECTION ON PAGE 20 OF THIS MANUAL FOR FURTHER INFORMATION ON MINIMIZING NOISE.
