SYSTEM CONNECTION DIAGRAM 2: Multiple Fathoms to

Home Theater Receiver or

Home Theater Preamp/Processor

To greatly simplify using multiple subwoofers in a single home theater system, Fathoms incorporate a “Master/Slave” signal distribution system. This allows control of all the Fathoms in a system from a single “Master” unit.

First, you will select one of the Fathom subwoofers as the “Master” via its upper “Input Mode” switch. Generally, you will designate the Fathom closest to the receiver/preamp as the master. In some cases; for example, when the control panel of certain units is difficult to access, you may prefer to designate the one which is easiest to access as the master.

Two connection types are available for connecting the master Fathom to your home theater 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 receiver or processor has balanced outputs, we highly recommend that you use them to connect to the Fathom designated as the master.

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 for the Fathom designated as the master (not both).

The remaining Fathoms in the system will be configured as “Slave” units via their upper “Input Mode” switches. Using balanced XLR cables, you will connect the master Fathom’s “Output to Slave” to the “Left or Mono” balanced input of the first slave Fathom. That slave unit’s “Output to Slave” connector will feed the “Left or Mono” input of the next slave unit via another balanced XLR cable. Subsequent slave units will be connected in the same manner.

IMPORTANT

Connections between the “Master” and “Slave” Fathoms and between “Slave” Fathoms are via balanced XLR cables ONLY.
