SYSTEM CONNECTION DIAGRAM 2: Multiple Fathom IWSs to

Home Theater Receiver or

Home Theater Preamp/Processor

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

First, you will select one of the Fathom IWS subwoofers as the “Master” via its upper “Input Mode” switch. Generally, you will designate the Fathom IWS 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 IWS 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 IWS designated as the master.

In the connection diagram at right, 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 IWS designated as the master (not both).

The remaining Fathom IWSs in the system will be configured as “Slave” units via their “Input Mode” switches. Using balanced XLR cables, you will connect the master Fathom IWS’s “Output to Slave” to the “Left or Mono” balanced input of the first slave Fathom IWS. 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” Fathom IWSs and between “Slave” Fathom IWSs are via balanced XLR cables ONLY.
