S mix Introduction and Features
Thank you for purchasing the S mix, miniature mixer by Samson Audio! The S mix is
a 5-channel compact mixer packed with high-end mixer features. The S mix features
a balanced microphone input on an XLR connector and includes phantom power for
connecting condenser microphones. Adding to the mix are two Super-Z, high imped-
ance line inputs on 1/4” connectors. Rounding out the inputs is a stereo channel with
two inputs on RCA connectors. Individual volume controls for the mic, lines and
stereo channels are also included for enhanced control over the connected signals.
And just because this unit is miniature, don’t be surprised by its great sound and reli-
ability thanks to high quality components and solid build construction.

Setting up the S mix
The basic procedure for setting up and using your S mix miniature mixer 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 AC/DC power adapter.
Note:Before plugging in and turning on, remember the “last on, first off” rule of power ampli-
fiers and powered speakers.When powering up your system, be sure that all the wires are con-
nected, turn your mixer and any other outboard gear on, and then last, turn your power amplifi-
er or powered speakers on. When powering down, turn your power amplifier or powered speak-
ers off first and then your mixer and outboard gear.
•Connect the supplied AC/DC adapter to the DC
Input on the rear panel of the S mix (Figure 1), then
plug the adapter into any standard AC outlet.
•Set the S mix volume control knobs to the following
default positions: All off. (Figure 2):
•Connect the S mix outputs to your power amp or
powered speaker using the Left
and Right RCA OUTPUT, or the
1/4” TRS jack OUTPUT connec-
tors.
Below is a wiring diagram for the
1/4”TRS stereo OUTPUT connector
(Figure 3).

Connecting Inputs Signals to the S mix
The S mix provides the capability of receiving signals from microphone, instrument and
line level devices.
Super-Z Line Inputs
Channel 1 and 2 inputs are Super-Z, line/instrument level inputs on 1/4-inch phone con-
nectors. The inputs can accept the signal from a variety of instruments level sources like
those from the outputs of guitars, bass guitars and clavinets, and line level signals like
those from the outputs MIDI keyboards, signal processors and drum machines, to name
some.
Mic input
The channel 3 Mic input will accept signal from any low impedance microphone. You can
use dynamic or condenser microphones since the S mix has phantom power present on
the microphone input at all times.
RCA Stereo Inputs
Channels 4/5 are stereo line level inputs and are ideal for connecting a CD, Cassette or
Mini Disk player. You can also run the signals from other line level devices such as key-
boards or drum machines here.

Creating a Mix
Now that you have connected your instruments and other sound sources to the S mix
inputs you can begin to create your mix. The best way to do this is to adjust one channel
at a time. Slowly raise the level control for the first input until you have reached the desired
level. Now, repeat the same for each additional input. You may want to go back and slight-
ly raise or lower an individual channel until you have set the balance between all the con-
nected inputs. Then, you have your perfect mix!
Typical Set-up
The diagram below shows a typical set-up for a small band using the S mix miniature
mixer. The vocalist’s microphone is connected to the channel 3 mic input, a bass guitar is
connected to channel 2 and channel 1 has a keyboard connected. For background tracks,
a CD player is connected to the channel 4/5’s stereo RCA inputs.
