Meeting the highest requirements of modern audio applications - especially, when it comes to sound
pressure level, coverage and sound quality - is only possible when using active multi-component
loudspeaker systems which provide the possibility to separately amplify and reproduce the audio signal's
individual frequency ranges. Active 2-way installations with additional sub woofer systems probably offer
the best price-performance ratio. The low frequency range of the audio signal is reproduced by the sub
woofers while high-quality full-range cabinets take care of the Mid/Hi frequencies and vocals.
One of the essential advantages when using active 2-way systems with additional sub woofers is the fact
that the vocals are not divided between several speaker systems. This, in return, offers more convenience
when adjusting the sound system. Unlike than with active 3- or 4-way configurations – difficult analyzing
and measuring of sound fields is unnecessary.
Since locating low-frequency sound is merely impossible, simply using monaural sub woofers is absolutely
sufficient for smaller stages or rooms. On wider stages it is indispensable to use individual sub woofer
systems for both sides. Otherwise, the level differences between bass and treble would result in audible
degradation of the overall sound. Of course, adding a centrally located sub woofer might additionally
improve the sound quality.
The AC
Controller has been designed to be used in high-performance installations that employ active

2-way systems plus sub woofers. Applications like these also mostly incorporate professional linear power
amplifiers like the Electro-Voice P1200, P2000, P3000 or Q44, Q66. When using processor controlled
power amplifiers like the Electro-Voice P1250, the processor section is simply switched off.
Installing and operating the AC
any complex detail about crossover functions and equalization. All controls for matching the sound to
different acoustic conditions and loudspeaker systems are located on the front panel. Difficult tasks - like
electronic signal routing and settings for instance - are automatically carried out inside the appliance. The
newly designed PowerMax12 crossover function (patents pending) optimally utilizes amplifier output
power and loudspeaker transmission capacities. Compared to conventional crossovers or controllers, this
results in an improved overall sound quality which is achieved with less effort.
The AC
Controller is also most suitable for integration in active 2-way instrument reinforcement

applications for keyboards, E-bass and drums. The PowerMax12 crossover function eliminates the often
complained about "lack-of-punch-and-definition", like it is common for conventional active musical
instrument reinforcement systems.
Its excellent dynamic range of more than 116dB, the extremely low noise level and the outstanding
price-performance ratio makes the AC
crossover and controller solutions – even in the critical field of permanent installation.
