S combine Introduction and Features
Introduction
Congratulations on your purchase of the S combine by Samson Audio! The S combine is a
two-to-one microphone combiner ideal for any situation where an extra microphone input
is needed. The S combine is a perfect solution for live sound applications, as well as, fixed
installations like schools, hotel meeting rooms and houses of worship. You can use your
S combine anytime two microphone inputs are needed and only one is available.
Whatever your situation, the S combine will provide high quality and reliable performance

oversized rubber bumper feet.

Operating the S combine
Setting Up the S combine
The basic procedure for setting up and using your S combine is simple and takes only a
few minutes. Remove all packing materials (save them in case of need for future service).
There are many different ways to use the S combine, however the basic connection is the
same in most installations and applications. The following example details the connection
for two microphones to a main PA mixer. Follow these simple steps to get connected.
•Using a standard XLR microphone cable, connect both mics to the S combine MIC
INPUTS.
•Using another standard mic cable, connect the BAL. OUT. 1 to the main PA mixer or
stage box.
