S phantom Introduction and Features
Introduction
Congratulations on your purchase of the S phantom by Samson Audio! The S phantom is a two-
channel, 48-volt phantom power supply capable of powering most any condenser microphones,
two at a time. The S phantom is a perfect solution for applications where the use of condenser
microphones is desired and the mixer, recorder, PA, or amplifier to be used does not provide
phantom power on the microphone inputs. Whatever your exact situation, the S phantom
will provide high quality and reliable performance thanks to its solid build construction based
around the extruded aluminum chassis and oversized rubber bumper feet.
In this manual, you’ll find a more detailed description of the features of the S phantom, as well as
a guided tour through the front and rear panels, step-by-step instructions for using the S phan-
tom, and full specifications. You’ll also find a warranty card enclosed—please don’t forget to fill it
out and mail it so that you can receive online technical support and so we can send you updated
information about other Samson products in the future.

Operating the S Phantom
Setting Up the S phantom
The basic procedure for setting up and using your S phantom is simple and takes only a few
minutes. Remove all packing materials (save them in case of need for future service) and check
to make sure that you remove the supplied DC power adapter.
Warning: Be sure to turn down the channel and master volumes of your mixer, PA or recorder
BEFORE connecting or disconnecting your microphone cables. All phantom power supplies, including
the S phantom, will make a loud pop when a microphone is connecting or disconnected during oper-
ation. Depending on the level of your system, the pop can damage your speakers or if you’re wearing
headphones, the pop may EVEN DAMAGE YOUR EARS! So be careful and be sure to turn down the vol-
ume of your mic channel, other inputs and master volumes before plugging or unplugging any mic
cables while the S phantom is powered on.
• Using a standard XLR microphone cable, connect the output of your condenser micro-
phone to the S phantom’s CHANNEL 1 INPUT.
• Using a second mic cable, connect the CHANNEL 1 OUTPUT of the S phantom to the micro-
phone input of the mixer, recorder, PA or amplifier you wish to connect your condenser
microphone to. If your recorder or mixer does not have an XLR input you can use the 1/4-
inch MIC 1 Output.
Note: There are several different input connectors that may be on your mixer or recorder, but they
will more than likely be either XLR or 1/4-inch phone. For a detailed wiring diagram see page 7 of this
manual.
• Repeat the steps above for the second microphone using the CHANNEL 2 INPUTS and
OUTPUTS.
• Plug the included DC adapter into the power outlet. Be sure to pay attention and confirm
the adapter is the correct voltage for your country. See specifications on page 8 of this manual.
• Press the 48V switch in to activate the phantom power.

Typical Set-up
The following diagram shows a
typical set-up for a project record-
ing studio using the S phantom
to connect two condenser micro-
phones to a personal hard disk
recorder that does not provide
phantom power.
Note: You can use either the XLR
or 1/4-inch phone jack output for
Mic 1 as depicted in the illustra-
tion by the dotted line.
For additional functionality, the
S phantom can be used as a one-
to-two mic splitter using the MIc1
XLR and 1/4-inch Outputs.
