Sub-Offer Active Or Passive
The active sabotage of the household is a built-in power force to remove the low-frequency load from the external force. In addition, it has an active crossover allowing high frequencies to be filtered and the harmonization with broadband acoustic systems is facilitated.
Active saboteur may receive a linear level signal (with pre-filled high frequencies) from a separate source channel. May be connected between a broadband acoustic system and a signal source (so-called cross-section). Many models have an additional function to adjust to the conditions of application (AFC adjustment, phase turn, cross-cutting positions and cut steep).
Area of application of active saboveurs.
Low sound frequencies are relatively poorly located with human ears, which is difficult to determine where the sound comes from. This effect enables the use of one household active sabotage on the whole acoustic system, and the remaining columns only complete medium- and high-frequency dynamics. This reduces the size and cost of equipment.
The active type of sabotage is used to record mass events. These include:
- concert sites (open and closed) and stadiums;
- in cinemas, cultural houses and cafés;
- at nightclubs, discotheques, etc.
