FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local 

voltage matches the voltage indicated on the unit, before you attempt to 

connect and operate the ULTRAGAIN PRO. Blown fuses may only be replaced 

by fuses of the same type and rating.

(17) 

MAINS CONNECTION. Use the enclosed power cord to connect the unit 

to the mains. Please also note the instructions given in the “Installation” 

chapter.

AUDIO IN. These are the audio inputs of your ULTRAGAIN PRO. The XLR 

connector is the common mic/line input. The line input is based on 

jack connection.

(19) 

AUDIO OUT. These are the audio outputs of your ULTRAGAIN PRO. 

Matching phone jack and XLR connectors are wired in parallel.

This section describes some typical applications of the BEHRINGER ULTRAGAIN 

PRO. Starting from the following basic settings you can use it to solve the 

majority of audio problems.
Please take your time to study the application examples, so as to be able to fully 

exploit the ULTRAGAIN PRO and its variety of features.
Basically, the ULTRAGAIN PRO can be used in five areas of application: 
1.  Using the ULTRAGAIN PRO as a high-quality microphone preamp.
2.  Using the ULTRAGAIN PRO to convert home recording to studio levels, 

and vice versa.

3.  Using the ULTRAGAIN PRO to balance unbalanced signals (DI box).
4.  Using the ULTRAGAIN PRO as a parametric equalizer specifically “tweaking” 

the frequency response.

5.  Using the ULTRAGAIN PRO to enhance the sound of the program material by 

adding “tube warmth”.

Before you can use the BEHRINGER ULTRAGAIN PRO as a preamp, we recommend 

that you study the various functions of the device. The high gain factors provided 

by the microphone preamp can produce extreme levels on the output side, 

which may damage subsequent devices. So, you should start with the following 

basic setting:

+48 V switch

OUT

MIC GAIN control

10 dB

MIC/LINE switch

LINE

PHASE REV. Control

LO CUT switch

EQ IN/OUT switch

Tab. 5.1: Basic setting of the ULTRAGAIN PRO

Reduce the volume level of the subsequent audio system to a minimum, 

and connect a microphone to the XLR input connector on the BEHRINGER 

ULTRAGAIN PRO. Use either the jack or XLR output connectors to connect the 

audio system. Owing to its output-side servo balancing circuit, the ULTRAGAIN 

PRO detects whether you use a balanced or unbalanced configuration and adjusts 

the level internally. 
Now, power up the entire equipment and press the MIC/LINE switch to activate 

the microphone preamp. If you wish to use a condenser mic requiring +48 V 

phantom power, please press the +48 V switch (to avoid electrical damage, 

please read chapter 5.1.5 “+48 V switch” below). 

5.1.2  MIC GAIN control
Configure the equipment according to the application on hand, speak into 

the microphone and turn the GAIN control clockwise until the 0 dB LED lights 

up. If your DAT recorder, mixing console or other subsequent devices have 

high-precision level meters, you can use these to verify the correct level setting.
The maximum output level depends on the device that follows next in the audio 

chain, and must therefore be set specifically. The high-precision level meter on 

the ULTRAGAIN PRO indicates the current operating level. The CLIP LED lights 

up at a level of +18 dBu signaling that you have an additional headroom of 

5 dB available, before the microphone preamp starts overloading. If distortion/

overloading occurs at high volume levels, you should reduce the gain with the 

MIC GAIN control.

5.1.3  PHASE REV. switch
The PHASE REV. switch reverses the audio signal’s phase by 180°. Usually, you won’t 

need this switch. However, in some cases, it might be necessary to reverse the signal 

phase, for example, if a microphone cable has been connected incorrectly (pins 2 

and 3 interchanged), or if several microphones are used and specific circumstances 

with regard to room acoustics are causing problems (e.g. frequency cancellations 

are usually caused by phase problems). The phase reverse function will help you 

locate and eliminate any such problem. 

5.1.4  LO CUT function
When you pick up acoustic signals with microphones, it is usually necessary 

to eliminate low-end signal portions, such as rumble or pop noise, or other 

interference frequencies. Often, such frequencies have very high amplitudes and 

do not only deteriorate the sound quality but can also damage the power amps or 

speakers. Your ULTRAGAIN PRO features a tunable high-pass filter with a very 

high slope. Press the LO CUT switch and adjust the FREQUENCY control, so that 

any disturbing frequencies are faded out as much as possible, with the least 

damage done to the actual audio signals. Press/release the LO CUT switch several 

times to make an A/B comparison.
