ULTRAVOICE XM1800S User Manual
1. Introduction
Thank you for expressing your confidence in us by purchasing
the BEHRINGER XM1800S dynamic microphone. The XM1800S
combines highest quality standards at an affordable price and
best results in audio perfomances for both vocal and instrument
miking applications. The features of the XM1800S will make it a
valuable tool for your recording and live performance.
2. Audio Connection
Use a standard microphone cable to connect your XM1800S to
any mixer, power mixer, amp, or mic preamp. Connect the female
XLR end to the XM1800S' male XLR input connector and the other
end of the cable, normally a male XLR connector, to the mixer,
power mixer, amp, or mic preamp.

3. How to Use your XM1800s
Most Effectively
Adjust the gain control in the microphone channel of your
mixing console so that the peak LED lights up only occasionally
or never at all. The EQ controls in the microphone channel should
be set to mid-travel position to start with; low-cut filter and
level attenuator should be turned off. Try to achieve the desired
sound by experimenting with the microphone position. Place the
microphone as close to the sound source as possible. The closer
your mic gets to the sound source, the greater the bass response
will be. On the other hand, as you move the sound source further
away from the microphone, the bass response will gradually roll
off (please see frequency response chart on next page).
Only when the desired basic sound has been achieved, should you
start to use equalizers and signal processors, if any at all.
(Remember: less is often more!)
All microphones have characteristic polar patterns that determine
how well signals from around the area of the microphone are
accepted or rejected.
The super cardioid pattern is used by the XM1800S.
Thus, the XM1800S excels in environments where a lot of
undesired ambient noise exists. The XM1800S excellently
reproduces those sound signals originated directly in front of
the microphone while rejecting or minimizing sound signals
originated in the area behind the microphone (please refer to the
polar pattern on next page for detailed information).
