[. . . ] DSP9024 User's Manual Version 1. 1 December 2001 ULTRA-DYNE PRO ® www. behringer. com ENGLISH ULTRA-DYNE PRO DSP9024 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electrical shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure--voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] The distance of a vocalist to the microphone becomes increasingly critical when using a compressor. Increasing amounts of background noise are transmitted the further the vocalist moves away from the microphone. Use the Gate function with long release times to "inaudibly" eliminate unwanted background noise during pauses. In live applications, drum crosstalk in piano tracks can be suppressed for example, or recordings cleaned of acoustic "contamination". 3. 2. 4 Reduction of feedback from stage microphones A vocalist singing into a stage microphone masks background noises, which are then no longer apparent. In pauses, however, the microphone picks up noise from the PA and monitor speakers, which can cause unpleasant feedback. This susceptibility to feedback can be reduced considerably if the ULTRA-DYNE PRO is inserted into the vocal channel and set to mute the microphone when it is not in use. In principle, all stage microphones should be included in this application. 3. 2. 5 Noise reduction in effects chains One of the most frequently overlooked sources of noise in a sound system is the effect rack. The prices of reverb and multi-effect devices have dropped drastically in recent years, making them standard equipment even in small studios and home recording environments. The noise level increases drastically with the number of devices, however, quickly spoiling the pleasure to be had from the new effects. This can be countered by inserting the ULTRA-DYNE PRO as the last unit in the effect chain and using the noise-reducing function of the Gate section. Set the unit for a long release time to ensure a natural reverb. 3. 2. 6 Creative application of the Gate section In addition to the applications described above, the Gate can also be used for the creative modification of audio characteristics. For example, the quality of environmental reverberation or the spatial impression of instruments can be modified. During its decay time, the reverberation of an instrument will drop below a user-defined threshold. The duration of the reverberation can be controlled using the preset threshold and release time. The adjustment of the release time permits the reproduction of the decay characteristic of the instrument in a manner that preserves the instrument's character. Take the time to experiment with modification of the decay of a signal. Long release times result in a slow fade, while short release times can completely remove the reverberation of the instrument. 3. 3 The Compressor section The purpose of the Compressor is to reduce the dynamic range of the program material and monitor the levels. The extensive selection of controls in the Compressor section permit a wide variety of dynamic effects, from gentle, musical compression, to the limiting of signal peaks, to an extreme, effective compression of the entire dynamic range. APPLICATIONS 23 ULTRA-DYNE PRO DSP9024 A low ratio and very low Threshold setting can be used, for example, to provide a soft, musical compression of the overall dynamic range of the program material.
