It is one of my most pleasant tasks to write this letter to you, because it is the culmination of many months of hard work delivered by our engineering team to reach a very ambitious goal: It also meant a lot of work and night shifts to accomplish this goal.
But it was fun, too. In return, we guarantee you uncompromising quality behringerr under ISO certified management system sng well as excellent technical and audio properties at an extremely affordable price.
All of this will enable you to fully unfold your creativity without being hampered by budget constraints. We are often asked how we are able to produce such high-grade devices at such unbelievably low prices. The answer is quite simple: Many satisfied customers mean large bwhringer volumes enabling us to get behrlnger conditions of purchase for components, etc.
Because we know that your success is our success too! Everybody has made very personal contributions, starting from the designers of the nehringer via the many staff members in our company to you, the user of BEHRINGER products. Noise as physical phenomenon Electrical noise is still one of the most unpleasant problems in the field of electro-acoustics.
The basic noise produced by a single unit is not considered to be annoying.
The combination behronger several instruments, effects devices and tape machines, however, results in a drastic increase in noise level. This requires the use of a noise reduction system. Conventional noise reduction systems Conventional noise reduction systems often suffer from several perceivable drawbacks: Effective noise reduction with minimal signal interference is the result.
Many years of experience in the field of noise reduction technology enabled us to design a system particularly suited to the highest demands. The ratio of which is automatically adjusted, dependent on the program material. The result is an expander which can be adjusted without deteriorating your audio.

Furthermore, the expander is more tolerant of those signals which appear slightly above the background noise. Furthermore, the extensive control features provide specific and successful processing of all sortes of program material.
It is useful for cleaning up studio tracks, tape duplications, motion picture sound tracks, during mixdown, and more. Be it noise reduction for instruments guitars, keyboards, etc. Please read the manual carefully and keep it for future reference. They boast extreme linearity and very low distortion characteristics. To complement this design the choice of components includes high tolerance resistors and capacitors, detented potentiometers and several other stringently selected elements.
Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit. Shipping claims must be made by the consignee. Please allow at least an additional 4″ depth for the connectors on the back panel. Be sure that there is enough space around the unit for cooling and please do not place the DENOISER on high temperature devices such as power amplifiers etc. The fuse holder on the female mains connector has 3 triangular markings, with two of these triangles opposing each other.
This instruction does not apply to export models exclusively designed, e.
It meets all of the international safety certification requirements. For your own safety, never remove or disable the ground conductor of the unit or of the AC power cable.
The circuit design features automatic hum rejection for balanced signals, permitting trouble-free operation even at highest operating levels. Externally induced power-line hum, etc. The automatic servo function recognizes the presence of unbalanced connectors and adjusts the nominal level internally to avoid level differences between the input and output signals 6 dB correction. Each channel is equipped with four push button switches, six rotary controls and 16 LEDs.
The unit is bypassed when the switch is not depressed. Once the signal falls below this threshold, the amount of expansion increases as the signal level decreases.
Low ratios, from 1. When, however, the ratio is set to 6: Thus, the filter can be adapted perfectly to various noise conditions. Thus, release time and corner frequency of the filter are automatically derived from the input signal. Please take the time to complete and return the warranty card within 14 days of the date of purchase, otherwise you will lose the right to the extended warranty.
Or just use our onlineregistration www. Blown fuses may only be replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder in two different positions, in order to switch over from V to V operation, and vice versa. The system design has to meet the following criteria: Most effective noise reduction while influencing the signal to the least possible extent.
No side effects such as pumping, noise tails, etc. Simple operation through comprehensive automation of control processes. To obtain maximum performance, it is necessary to understand what is achieved by each of the separate filter and expander sections and how they perform together. Once you understand how these circuits work, it will be easier to set up the controls correctly to suit any application.
The noise reduction effect of the expander section is active only when signal levels are low. The filter section, on the other hand, is active at all times over the complete dynamic range.
Since the filter section is always active, let us look at what is happening in that circuit first: One of the basic components of BEHRINGER circuitry is a dynamically controlled low-pass filter which allows low frequencies to pass but filters the high-frequency information, depending on the music material. This is the range where noise is considered most annoying. The cut off frequency of the filter depends on both the input level and the frequency range of the audio signal.
With no audio signal present, the dynamic filter will close down to a user selectable cut off point. This cut off point is adjustable between Hz and 6 kHz. If the cut off was set for 1 kHz, the bandwidth of the filter would be from 20 Hz to 1 kHz.
If an input signal had a bandwidth from 20 Hz to 2 kHz, the filter would open far enough to pass up to the 2 kHz frequency and its harmonics, while reducing any noise present from approximately 2 kHz to 20 kHz.
If a broadband signal with frequency components up to 20 kHz appears at the input, the dynamic filter would open all the way to 20 kHz. Operation of the dynamic filter With a low-frequency input signal present, the dynamic filter will reduce any mid or high-band noise as well as any disturbing noise tails. If the input signal is dominated by high-frequency components, however, the dynamic filter will open to its full extent to let the signal pass, maintaining high-frequency information.

However, its realization poses many problems. The control times of the dynamic filter must be fast enough so that high frequencies will not be cut off. Thus, the sound of signals with a high slope, such as percussive instruments, will not be modified.
While the RMS rectifier calculates the average or mean value of the signal, i. Thus, the TAC circuit is capable of reacting much faster to abrupt level changes produced by percussive signals.
The delay which the integration time behrnger in RMS rectifiers is eliminated in a peak detector, i. If the adjusted value is, for example, dBu, highfrequency signals with a level above dBu cause the filter to behringerr. Under most conditions, this control should be set at Hz, allowing for the maximum possible amount of noise reduction. The cut off frequency should be increased if you want to affect noise in the upper portion of a signal only or if too drastic noise reduction leads to unwanted side effects.
