27、iven 3-Weg oder 4-Wegsystemen- nichtnotwendig. Auf kleinen Bhnen oder in kleineren Rumen kann mit einem Mono-Subwoofer gearbeitet werden weil die Bsse unter derartigen Bedin-gungen kaum geortet werden knnen.

Einzentral angeordneter Mono-Subwoofer kann natrlich vorteilhaft alsErgnzung eingesetzt werden.Der ACONE Controller wurde zum Aufbau hchstwertiger Aktiv-2-Weg-systeme mit Subwoofern entwickelt.

29、 Als Leistungsverstrker werdenin derartigen Systemen professionelle lineare Leistungsendstufen wiebeispielsweise Electro-Voice P1200, P2000, P3000 oder Q44, Q66eingesetzt. Beim Einsatz von Prozessorendstufen wie beispielsweiseElectro-Voice P1250 wird der Endstufenprozessorteil einfach ausge-schaltet

The low frequency range of the audio signal isreproduced by the sub woofers while high-quality full-range

36、cabinetstake care of the Mid/Hi frequencies and vocals.One of the essential advantages when using active 2-way systems withadditional sub woofers is the fact that the vocals are not divided betweenseveral speaker systems. This, in return, offers more convenience whenadjusting the sound system. Unlik

37、e than with active 3- or 4-way confi-gurations difficult analyzing and measuring of sound fields is unne-cessary.Since locating low-frequency sound is merely impossible, simply usingmonaural sub woofers is absolutely sufficient for smaller stages orrooms. On wider stages it is indispensable to use i

38、ndividual sub woofersystems for both sides. Otherwise, the level differences between bassand treble would result in audible degradation of the overall sound. Ofcourse, adding a centrally located sub woofer might additionally impro-ve the sound quality.The ACONE Controller has been designed to be use
