Samson S12 - Manual (Page 2)

Using Your S12
The S12 can be connected to any standard mixer,
mixer/amplifier, or mic preamp using a standard low
impedance microphone cable. Connect the female XLR
end directly to the S12 and the other end (normally a male
XLR end, although some mixers use 1/4" connectors) to
the mixer, mixer/amplifier, or mic preamp.
The S12 can be mounted to any standard microphone
stand (using the included mic clip) or can be handheld. If
handheld, take care not to cover the head grille with your
hand. Be aware of a phenomenon called the
proximity
effect which causes a noticeable increase in low frequen-
cies (bass response) when a microphone is close to the
audio source. This can have positive impact—for exam-
ple, it will cause your voice to sound much fuller when you
sing close to the mic than when you sing at a distance.
On the other hand, the proximity effect can make some
instruments too boomy when the mic is too close—for
example, when miking an acoustic guitar, you may want to
move the S12 back six inches or more from the front of
the guitar body. The key is experimentation, along with
awareness of the general principle that, the closer the S12
is to a signal source, the greater the bass response.
Every microphone has a characteristic polar pattern that
determines how well it accepts or rejects signal coming
from various areas around the microphone. For example,
omnidirectional mics accept all signals regardless of
wherever those signals originate (in front of the mic,
behind it, to the side, etc.). In contrast, directional
cardioid
mics are specifically designed to accept mostly signal
coming from directly in front, and to reject signal coming
from behind or from the side. The most extreme variation
of cardioid is the
hyper-cardioid pattern utilized by the
S12; this yields maximum rejection of signal coming from
any direction other than directly in front of the mic. For
this reason, the S12 excels in environments where there is
a good deal of unwanted ambient sound—it reproduces
those signals originating directly in front of the mic cap-
sule itself while rejecting those that originate from behind.
The polar pattern also determines how prone a particular
mic is to inducing
feedback. Feedback is that characteris-
tic nasty howling sound that occurs when a mic is placed
too close to a loudspeaker—the signal from the loud-
speaker is fed into the mic, then into the loudspeaker, then
into the mic, over and over again until an oscillating tone
is generated. Because the hyper-cardioid pattern utilized
by the S12 is so good at rejecting signal not coming from
directly in front of the mic, you’ll find that use of the S12
greatly minimizes feedback problems when used in live
performance.
