ULTRAGAIN PRO MIC2200 1. INTRODUCTION With the ULTRAGAIN PRO you have purchased an extremely musical and flexible microphone preamplifier. Our ULTRAGAIN range of devices has been a hit ever since we introduced our first model some 5 years ago. This high-end microphone preamp is based on many years of experience and findings in amplifier technology and is used throughout the world in renowned studios, sound reinforcement systems as well as in broadcast and television studios.
ULTRAGAIN PRO MIC2200 1.1 Technical background By employing current modern analog technology it is possible to manufacture audio equipment with a dynamic range of up to 130 dB. In contrast to analog techniques, the dynamic range of digital equipment is approximately 25 dB less. With conventional record and tape recorder technology, as well as broadcasting, this value is further reduced.
ULTRAGAIN PRO MIC2200 It is therefore useful to keep the operating level as high as possible without risking signal distortion in order to achieve optimum transmission quality.

ULTRAGAIN PRO MIC2200 With the introduction of semiconductor technologies in the field of audio amplification, it soon became clear that the tube would have to give way to the transistor, as this device featured an enormously enhanced signalto-noise ratio, required a less complex power supply and yielded an improved frequency response. Plus, semiconductor-based circuits can be realized much more easilyfor less money.
ULTRAGAIN PRO MIC2200 Fig. 1.5: pentode In a triode the capacitance between grid and anode is a problem with regard to high frequencies and large amplification factors. For this reason, the pentode has a positively charged screen grid between the control grid and the anode. However, the positive charge of the screen grid attracts electrons emitted from the anode plate when it is hit by arriving electrons.
ULTRAGAIN PRO MIC2200 1.2.4 The best of both worlds Despite many efforts neither manufacturers nor developers have succeeded so far in simulating these positive properties of the tube by means of other devices. Additionally, the natural capabilities of the tube to act as a soft limiter can only be mimicked with highly sophisticated circuitry. Todays studio technology requirements are therefore met by a combination of both high-grade semiconductor and tube technologies.
ULTRAGAIN PRO MIC2200 3.1 Rack mounting The BEHRINGER ULTRAGAIN PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at least an additional 4" depth for the connectors on the back panel. Be sure that there is enough air space around the unit for cooling and please do not place the ULTRAGAIN PRO on high temperature devices such as power amplifiers etc. to avoid overheating. 3.
ULTRAGAIN PRO MIC2200 + Never use unbalanced XLR connections with microphone cables, as this would short-circuit any phantom power transmitted over these cables! 4. CONTROL ELEMENTS 4.1 Front panel control elements Fig. 4.1: Control elements on the front panel 1 + 2 + This +48 V switch activates the +48 V phantom power circuit that uses the signal leads to supply condenser microphones with the required operating voltage.
ULTRAGAIN PRO MIC2200 9 The x 0.1 switch lowers the working range of the FREQUENCY control to 10 - 200 Hz, so that you can process the bass end of the audio spectrum. 10 The x 10 switch raises the working range of the FREQUENCY control to 1 - 20 kHz, so that you can process the treble end of the audio spectrum. 11 The BANDWIDTH control determines the slope or quality of the filter. Bandwidth ranges from 0.03 (Q = 43) to 2 octaves (Q = 0,67).
ULTRAGAIN PRO MIC2200 5. APPLICATIONS 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.
ULTRAGAIN PRO MIC2200 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 signals phase by 180°. Usually, you wont need this switch.
ULTRAGAIN PRO MIC2200 Never switch on the +48 V supply when you use unbalanced microphones, as this could cause electrical damage. Some people hold that the sound of dynamic microphones is affected when the +48 V supply is on, or that ribbon microphones cannot be operated from an input equipped with +48 V phantom power. None of these statements is true. As a matter of fact, problems of this kind are caused by one of the following reasons: 1.
ULTRAGAIN PRO MIC2200 Notching out specific interference frequencies and narrow-band resonances (uncontrolled frequency peaks) is one of the ULTRAGAIN PROs major tasks: by tuning the EQ in to the precise trouble frequency, interference such as hum and noise caused by air conditioners, etc. can be eliminated without affecting adjacent frequency ranges. Basic acoustic problems usually encountered in studios and stage systems can be solved elegantly with the ULTRAGAIN PRO.
