1. INTRODUCTION The BEHRINGER ULTRAMIZER PRO is a digital sound processing device based on a sophisticated DSP, using 20 bit A/D and D/A converters. The high speed DSP is capable of performing the calculations needed for the complex algorithms in fractions of a second, the only element affecting its performance being the software. Despite extensive computing work which is done in the DSP1400P by a dual-engine 24-bit processor, the ULTRAMIZER PRO can be operated easily and conveniently.
The mains connection of the ULTRAMIZER PRO is made by using the supplied cable. It meets all of the international safety certification requirements. Please make sure that all units have a proper ground connection. + Before you connect your ULTRAMIZER PRO to the mains, please make sure that your local voltage matches the voltage required by the unit (see chapter 5.2 for details)! As a standard the audio inputs and outputs on the BEHRINGER ULTRAMIZER PRO are fully balanced.
5 Next to the display, the appropriate unit lights up to indicate the correct value which is being edited. These eight LED illuminated units are very important with keys which can represent more than one parameter. Fig. 1.3: Function keys and jog wheel 6 + With the jog wheel, a continuous rotary control, you can freely edit the selected parameters. Turn the wheel clockwise to increase the values or counter-clockwise to reduce them.
b) When pressed a second time the SENSITIVITY can be adjusted (SENS will light up in the display). This governs the sensitivity of the dynamic high cut filter and how it reacts to the input signal. The value ranges from 0 to 100. 11 When the LEFT key is pressed only the settings for the left channel are edited. 12 Use the RIGHT key to select the right audio channel. + 13 If you wish to process the left and right audio channels simultaneously (COUPLE mode), press both LEFT & RIGHT keys together.
17 Use the POWER switch to switch the ULTRAMIZER PRO on or off. 1.3.2 Back panel Fig. 1.4: Back panel connectors and control elements 18 Use the OPERATING LEVEL switch to adapt the ULTRAMIZER PRO to different operating levels. You can select a -10 dBV semi-pro level used for home recording and a +4 dBu level used in professional studios. This way the ULTRAMIZER PRO is always optimally adapted to the used nominal operating level. 19 These are the ULTRAMIZER PROs analog INPUTS.
go hand in hand with the warm and powerful sound of analog devices. The ULTRAMIZER PRO combines multiple functions for the processing of stereo signals in one device. It is a multi-band Compressor, a 3DSurround Processor, a Denoiser as well as an Exciter and a Bass Processor. Despite this unbelievable processing power the DSP1400P can be intuitively operated with an audio quality previously unimaginable. 2.1.
maximum level. You can switch between these two modes by pressing the MAX. OUT LEVEL key for about 2 seconds. Additionally the RMS LED in the display will light up. 2.1.3 The Exciter function The ULTRAMIZER PROs Exciter function adds transparency and depth to the audio signal. Classical music material gains transparency and musicality while popular music keeps the desired brilliance. Two parameters govern the performance of the Exciter function, both can be accessed by means of the EXCITER key.
you determine the sensitivity of the dynamic high cut filter. This function is highly useful to remove noise from the music signal. To indicate that the sensitivity is being edited the SENS LED beside the numeric display lights up. + The optimal adjustment of the SENSITIVITY parameter depends strongly on the type of noise and program material. Take the time to set the SENSITIVITY parameter with care. 2.1.
another preset that can be overwritten. Press the PRESET key a third time to save the edits to the selected preset. If you wish to overwrite the original preset, simply press the PRESET key three times (after editing) to save all changes you have made. + Whenever you have edited a preset and pressed the PRESET key three times, all previous settings in this preset are erased and overwritten with the new parameter values.
d0 means that no SYSEX data will be sent or accepted. d1 will enable the ULTRAMIZER PRO to receive data. When PRESET is pressed the unit will wait for data, this is shown by flashing dots (LEDs) in the display. The MIDI button LED flashes signaling that SYSEX data is being received. d2 will enable the ULTRAMIZER PRO to send a bulk dump. Start your sequencer and press PRESET on the unit to start the transmission.
3.2.1 The ULTRAMIZER PRO in analog recording In the recording and duplication field the goal should always be to achieve an optimum recording level onto the recording media. Too low or too high recording levels lead to side effects such as noise, distortion etc. In mastering and multitrack recording, as well as in duplication, one should always take care to utilize the full dynamic range of the tape recorder, DAT recorder etc.
otherwise side effects could become audible. 2. Therefore, in addition, you should also use the ULTRAMIZER function. It is recommended that the compression is limited to the first 6 dB of the dynamic range only. You can monitor the gain reduction with the help of the GR LO and GR HI gain reduction meters. The cut signal peaks cause a reduced recording level of about 6 dB, which is visible on the level indicators of the DAT recorder. Now increase the recording level of the recorder back to normal.
seem at first, can be explained with the fact that especially low-frequency signals with high amplitudes can overload the power supply in the amplifier(s). The resulting clipping (cutting off of signal peaks) produces distortion (upper harmonics), which is abruptly added to the midrange/tweeter signals. For this reason, weak power amps, in particular, must be protected by a limiter in their input dynamics. 3.3.
dynamics and transients audibly. With television broadcasts varying volume levels can cause problems: Announcements, jingles, dialog and background music can differ strongly in level. Here too the ULTRAMIZER PRO can level out these differences in the program material and can thus provide a constant volume. Moderate use of the Compressor, Peak Limiter, Super Bass and Exciter section of the ULTRAMIZER PRO will help to achieve high and distortion-free nominal volumes without loss of liveliness. 3.5.
3.7 The ULTRAMIZER PRO in a MIDI setup Owing to the integrated MIDI interface you can fully control the DSP1400P in a MIDI Setup. The ULTRAMIZER PRO can both receive and transmit Program CHANGES and CONTROLLER CHANGES. Wire the unit as follows.

4.1.1 Noise as a physical phenomenon All electrical components produce a certain level of inherent noise. Current flowing through a conductor leads to uncontrolled random electron movements. For statistical reasons, this produces frequencies within the whole audio spectrum. If these currents are highly amplified, the result will be perceived as noise. Since all frequencies are equally affected, we term this white noise. It is fairly obvious that electronics cannot function without components.
E Fig. 4.3: The interactive relationship between the operating level and the headroom The need therefore arises for a fast acting automatic gain control system which will constantly monitor the signals and which will always adjust the gain to maximize the signal-to-noise ratio without incurring signal distortion. This device is called a compressor or limiter. This system is a part of the BEHRINGER ULTRAMIZER PRO. 4.1.
4.1.4 Expanders/Noise Gates Audio, in general, is only as good as the source from which it is derived. The dynamic range of signals will often be restricted by noise. Synthesizers, effects devices, guitar pickups, amplifiers etc. generally produce a high level of noise, hum or other ambient background hiss, which can disturb the quality of the program material. Normally these noises are inaudible if the level of the desired signal lies significantly above the level of the noise.
4.4 Super Bass Apart from processing the upper harmonic ranges, users of the BEHRINGER ULTRAMIZER PRO have access to an innovative Bass Processor. The numerous stages of processing during the recording, reproduction, copying and effecting processes, increasingly delay the phase of the bass frequencies, when compared to the remaining frequency ranges. This is why the low-frequency range suffers from a loss in power and fundamental bass definition.
