Fathom SA
-600W
12V Trigger
Equipped with dual mini jacks, the SA-600W can be activated using a 12V
trigger signal (Input) and turn on another component (or additional SA-600Ws)
any time the SA-600W is on (Output). Both jacks accept standard 1/8-inch (3.5
mm) plugs (not supplied), with +12V connected to the “tip” conductor and Ground
connected to the ring and/or sleeve conductor(s). Refer to 12V Trigger on page 12 for
more info.
Main Fuse Holder
Located on the rear panel, next to the AC cord receptacle is the main fuse
holder’s cover. This small spring-loaded cap may be removed, allowing access to
inspect or replace the main power fuse. If your AC outlet has power but the SA-
600W’s LED and LCD Display do not come on, the main power fuse may be blown.
To Remove - Unplug the SA-600W’s AC power cord. Insert a small flathead
screwdriver into the cap’s slot and turn counter-clockwise slowly until the
fuse holder is released. Once removed, the fuse can be inspected and, if
necessary, replaced. Refer to the chart below for fuse values for your specific
SA-600W model.
To Reinstall - Note that the fuse holder’s body is keyed to the opening and
must be aligned to fit properly. Insert the fuse holder into the opening and
gently turn clockwise (about 1/8 turn) to lock in place. Pressing the cap and
feeling for the spring to compress will help to locate the correct position.
Reconnect the AC power cord.
If the replacement fuse blows immediately after replacing a fuse replacement,
the SA-600W may require service. Please contact your Authorized JL Audio
Retailer or Distributor.

IEC-Style AC Connector
The IEC-style AC cord receptacle receives the heavy-gauge, 6 ft. (1.8 m) long,
power cord included with your SA-600W. Amplifiers sold in different parts of the
world are configured for each market’s electrical system and include appropriate
plugs on the power cords. Please note the voltage markings next to the AC
Connector and make sure you are only powering the SA-600W from a receptacle
that matches these markings. Do not use any AC power cord other than the one
supplied with the SA-600W.
The SA-600W is a very powerful device and can draw a lot of current. If too
many components are connected with a SA-600W to one electrical outlet, you risk
tripping a household circuit breaker during very demanding program material.
If this happens, separate the SA-600W and other components between two AC
electrical circuits.
