TUBE ULTRAGAIN MIC100
Welcome to the BEHRINGER family!
Thank you for the confidence you have placed in us by purchasing
the MIC100.
Your MIC100 is a professional mic preamp that can be used in a
variety of applications. Due to its incredible functionality and the
broad range of connection options, the MIC100 ensures outstanding
performance. You will soon appreciate the MIC100’s flexibility, be it
live on stage or in the home/professional recording studio.
1. INTRODUCTION
With the MIC100, you have purchased an extremely musical mic
preamp that is equipped with a 12AX7 vacuum tube. An integrated
limiter, a phase reverse function, phantom power supply, a highly
accurate LED meter and a switchable pad function complement this
powerful device.
1.1 The design concept
The heart of the TUBE ULTRAGAIN is an extremely low-noise
microphone preamp circuitry that uses discrete components and
produces a highly trans-parent sound. In combination with our
BEHRINGER tube technology, the operational amplifiers 4580 and a
sophisticated circuit topology, the TUBE ULTRAGAIN yields excellent
noise and distortion properties. The innovative UTC circuitry that has
been developed by our engineering team offers an abundance of
sound-shaping possibilities. Absolute musicality was our major goal
when we designed the TUBE ULTRAGAIN. The result is a device that,
thanks to our tube circuitry, lends an incredible punch to percussion
instruments. On the other hand, instruments that are rich in upper
harmonics will receive more transparency. The sound will be warm,
detailed and brilliant.
Surely you know the recording problem that single instruments or
vocals sometimes don’t cut through. Thanks to the TUBE ULTRAGAIN,
vocals gain in presence and volume without masking other instruments.
As a result, your voice will be perfectly integrated in the mix.

2.1 Connections (side panel)
Use the POWER SUPPLY CONNECTOR to hook up the enclosed
power supply unit. Next to this connector you’ll find the strain
relief clamp, which prevents accidental release of the power
supply.
This is the balanced XLR OUTPUT of your MIC100. Use this
connector to feed the XLR input of your mixing console,
multitrack recorder or power amp.
The balanced 1/4" TRS OUTPUT of your MIC100 can also be
connected to either mixer, recording system or power amp.
+
Please note that you can use the XLR and TRS outputs of
your MIC100 at the same time! Thus, it is possible to
connect the MIC100’s output signal to two different devices
simultaneously.
The balanced 1/4" TRS INPUT of your MIC100 can be used to
connect your electric guitar, for example. This input is wired
parallelly to the XLR input.

Use the balanced XLR INPUT to connect your microphone.

In contrast to its outputs, the MIC100’s inputs should
never be used simultaneously!
2.2 User interface

The GAIN control allows applying gain from +26 to +60 dB to the
input signal. This control should be set fully counterclockwise
when (dis)connecting a sound source to the MIC100. When all
connections are made, slowly start raising gain.
We recommend using the LED meter to adjust gain. The
LED chain displays the output signal level in dB. Please make
sure that the clip LED never lights up permanently. It should
light up only at peak signals, but never all the time.

If your MIC100 is connected to the mains via the enclosed
power supply unit, the POWER LED lights up to indicate that
your MIC100 is running.
The 20 dB PAD button reduces the input sensitivity by 20 dB.
The appropriate setting depends on the equipment connected.
No matter what your application is, the clip LED warns you to
reduce the gain setting, so as to avoid distortion.
This +48 V switch activates the phantom power supply for the
XLR input. Phantom power supply is required for operating
condenser microphones.
With the PHASE REVERSE switch, the input signal is reversed
by 180°. This function is available for both mic and line signals.
Use this function in a multi-microphone setup if you detect
phase cancellations in specific frequency bands.
Use the LIMITER switch to limit the signal and to prevent
distortion.
The OUTPUT control governs the output level of the device
within a range from -oo to +10 dB. If the control is set fully
counter-clockwise, there is no output signal at all. The more the
control is set clockwise, the higher the output level.
2.3 Serial number
The MIC100’s serial number is located on the bottom cover. Please
take time to fill in and return the warranty card within 14 days after the
date of purchase, so as to benefit from our extended warranty. Or

3.1 Enhancing vocals and instruments in live applications
Here, the MIC100 is wired before the mixer’s channel input. Thus,
the sound gains in warmth and transparency. Due to the integrated
limiter, distortion is eliminated effectively.

3.2 “Direct to disk” application in studio or home recording
environments
If you are looking for a device that considerably enhances the sound
of your digital workstation, this is where the MIC100 comes in. Many
hard disk recorders lack a certain “liveliness”. In addition, they are
often equipped with “lousy” microphone preamps. Such problems can
be solved perfectly with the MIC100.

3.3 The MIC100 as DI-box
Your MIC100 is excellently suited for this application. For example,
you can connect an unbalanced acoustic guitar signal to the MIC100
to prevent hum or interference noise. What you get is a balanced,
noise-free signal.
