Connecting Your Fathom Iwsv2(S) - JL Audio Fathom IWS 113-A Bedienungsanleitung

The Left and Right inputs on the
Fathom IWSv2 are internally summed
to a single mono channel. Since the
Fathom IWSv2 is inherently a "mono"
or single channel device, you can use
the Left and Right inputs for the master
Fathom IWSv2 and then distribute the
summed mono signal to additional
slave Fathom IWSv2s in the system.

CONNECTING YOUR Fathom IWSv2
Balanced Inputs
If your home-theater receiver or preamplifier/processor provides
balanced outputs, the Fathom IWSv2 amp's balanced inputs are the preferred
connection. Balanced connections are used extensively in professional
studios and sound reinforcement applications for a number of very
good reasons. Besides ensuring proper grounding between components,
balanced signal transmission is designed to cancel induced cable noise
from the surrounding environment (particularly important with long cable
runs). The bottom line is that your system will be far less likely to exhibit
humming or other extraneous noises if you use balanced connections.
The Fathom IWSv2 subwoofers feature individual left and right balanced
input connections with XLR "combo" jacks. These special jacks accept either a
three-pin male XLR connector or a "tip-ring-sleeve" (TRS) 1/4-inch (6.3 mm)
connector for compatibility with a wide range of equipment.
For systems with a mono subwoofer or "LFE" channel connection, only the
jack labeled "Left or Mono" will be used. This applies to most modern multi-
channel receivers and preamplifier/processors. Separate left and right input jacks
are provided for systems without a dedicated mono subwoofer connection. This
typically applies to two-channel audio equipment.
Appropriate balanced cables are available from your JL Audio dealer and are
not included with the Fathom IWSv2.
Technical Notes:
• Do not use the balanced inputs with unbalanced signals via adaptors.
The unbalanced inputs of the Fathom IWSv2 are preferable in situations where
only an unbalanced signal source is available. Balanced input impedance is
20 kohms.
• Input connectors are configured according to Audio Engineering Society
recommendations for balanced signal cables as follows:
XLR Connection
Pin 1: Shield
Pin 2: Positive
Pin 3: Negative
TRS connection:
Tip: Positive
Ring: Negative
Sleeve: Shield
IMPORTANT! IF YOUR RECEIVER OR PREAMPLIFIER/PROCESSOR DOES NOT
HAVE XLR OR 1/4-INCH TRS BALANCED OUTPUTS, PLEASE REFER TO THE
"UNBALANCED INPUTS" SECTION ON PAGE 18 FOR INPUT CONNECTION
INFORMATION. DO NOT ATTEMPT TO CONNECT UNBALANCED OUTPUTS
TO THE FATHOM IWSv2'S BALANCED INPUTS VIA ADAPTORS.
