350x • GETTING STARTED
Connecting Your Speaker Cabinets
The 350x is a mono amplifier, which makes things fairly simple. Locate the "Speaker Outputs" section on
the rear of the amp. You will notice that there are four different speaker output jacks, two 1/4" type and
two Speakon type jacks. The Speakon jacks are preferable if your speaker cabinet is equipped with
Speakons as well; however, you can use any of the four available jacks to connect your speaker(s) to the
350x.
Using One Speaker Cabinet
Using a speaker cable of 18 gauge or heavier (the heavier the cable, the lower the gauge), simply connect
any one of the 350x's Speaker Output jacks to the input jacks of your speaker cabinet. If your cabinet is a
4 ohm enclosure, the 350x will deliver 350 watts into it. If your cabinet is an 8 ohm enclosure, it will deliv-
er 240 watts into it. Be sure to check the power handling capabilities of your speaker cabinet before con-
nection and operation.
Using Two Speaker Cabinets
Using a speaker cable of 18 gauge or heavier (the heavier the cable, the lower the gauge), simply connect
any of the 350x's Speaker Output jacks to the input jacks of your two speaker cabinets. (You can use one
1/4" and one Speakon Output jack each if you wish; however, it is always best to use speaker cables with
similar type ends.) If the cabinets are the same impedance, the same amount of power will be sent to
each enclosure. If the cabinets are different impedances, more power will flow to the cabinet with the
lower impedance. Since the 350x is a mono amplifier and individual cabinet levels cannot be adjusted, it is
recommended that you use cabinets of the same impedance when using more than one cabinet. If you use
two 8 ohm cabinets—the two-cabinet setup recommended by SWR—the resulting "total" impedance will be
4 ohms, and the 350x will deliver 350 watts spread across both cabinets. Needless to say, in all cases,
be sure to check the power handling capabilities and impedance of your speaker cabinet(s) before connec-
tion and operation.
Important: The minimum total impedance when operating the 350x is 4 ohms. This means you can
safely use:
a) A single 8 ohm cabinet
b) A single 4 ohm cabinet
c) Two 8 ohm cabinets (total: 4 ohms)
More details are available in the "Speaker Outputs" section of this manual, and we strongly recommend
that you read the entire manual. However, this should be enough information to get you started.
