Take a look through our user manuals in our on-line library, with instruction manuals and service handbooks downloadable in PDF format. Everybody has made very personal contributions, starting from the designers of the unit via the many staff members in our company to you, the user of BEHRINGER products.
Noise As A Physical Phenomenon What Are Audio Dynamics? High Quality Components And Design Inputs And Outputs Rack Mounting Mains Voltage Audio Connections Selecting The Operating Level The Front Panel Control Elements Compressor Section Peak Limiter Section The unit was particularly designed for those applications most frequently used in practice. Despite the extremely complex internal circuitry, the unit has a control surface which is clearly laid out and easy to understand.
Usually, four simple compressor sections are packed into one enclosure, representing however a compromise in terms of operation and functionality. In 1 RU package the unit consists of four independent high-precision compressor sections with sidechain filters and four peak limiters, each offering all the required controls.
Additionally, we have succeeded in refining the audio properties as well as the circuit topology. The response of a compressor and the quality of dynamics processing largely depend on the control times, i.
The interactive AUTO processor derives the attack and release times automatically from the programme material, a function that avoids misadjustment of the control times, which is a problem often encountered in conventional designs. Above an adjustable threshold the peak limiter begins to function and restricts signal peaks radically clipper. If however, the threshold of the limiter was surpassed for more than a few milliseconds, the IGC circuit automatically kicks in and reduces the level of the.
After the level falls below the threshold, the signal returns to the original value after a period of about 1 second. This IGC circuit proves to be extremely valuable as much for live work loudspeaker protection as for digital situations, where any extreme signal peaks would exceed the maximum headroom and therefore would cause severe problems. After you have read the instructions carefully, please put them away safely, so that you can refer to them again if necessary.
By employing current modern analogue technology it is possible to manufacture audio equipment with a dynamic range of up to dB. In contrast to analogue 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. Generally, dynamic restrictions are due to noisy storage in transmission media and also the maximum headroom of these systems.
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.
Even if special low-noise components are used, a certain degree of basic noise cannot be avoided. This effect is similar when replaying a tape. The non-directional magnetic particles passing the replay head can also cause uncontrolled currents and voltages.
