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)
(1)
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.
(2) 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.
(3)
The balanced ¼" TRS OUTPUT of your MIC100 can also be connected to either mixer, recording system or power amp.
(4) The balanced ¼" TRS INPUT of your MIC100 can be used to connect your electric guitar, for example. This input is wired parallelly to the XLR input.
(5)
Use the balanced XLR INPUT to connect your microphone.
◊ In contrast to its outputs, the MIC100’s inputs should never be used simultaneously!

(6)
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.
(7) 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.
(8)
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.
(9) 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.
(10)
This +48 V switch activates the phantom power supply for the XLR input.
Phantom power supply is required for operating condenser microphones.
(11) 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.
(12)
Use the LIMITER switch to limit the signal and to prevent distortion.
(13) The OUTPUT control governs the output level of the device within a range from
-∞ 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.
The device’s SERIAL NUMBER is found on the bottom side of the unit.

3. Wiring Examples
You’ll be surprised how flexibly you can set up your MIC100. The following chapter describes some typical wiring examples.
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.
