PowerMax 230 Controller

”PowerMax” - a crossover-functionthat provides improved SPL in the frequency range around the crossover frequency, making it the ideal solution for systems with relatively compact dimensionedfull-rangespeakers plus sub woofer.

Meeting the highest requirements of modern audio applications is only possible when using active multi-compo-nent loudspeaker systems which provide the possibility to separately amplify and reproduce the audio signal’s individual frequency ranges. Active2-wayinstallations 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 highqualityfull-rangecabinets take care of the Mid/Hi frequencies and vocals.

One essential advantage of active 2-waysystems with additional sub woofers is the fact that the vocals are not divided between different speaker systems. This, in return, offers more convenience when adjusting the sound system. Opposite to active 3- or4-wayconfigurations, difficult analysing and measuring of sound fields is unnecessary.

Using individual sub woofer systems for each side is essential on wider stages. 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 PowerMax230 Controller has been designed for use in high-performanceinstallations that employ active2-waysystems plus sub woofers. Applications like these also mostly incorporate professional linear power amplifiers like DYNACORD LINEARor STANDARD PRECISION power

amps. Installing and operating the PowerMax230 Controller is easy as can be, since the user does not need to know 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 PowerMax12 crossover function 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 PowerMax230 Controller is also most suitable for integration in active 2-wayinstrument reinforcement applications for keyboards,E-bassand drums. The PowerMax12x-overfunction eliminates the often complained about“lack-of-punch-and-definition”,like it is common for conventional active musical instrument reinforcement systems. TheEQ-sectionprovides additional tools:

The Lo-EQis an adjustableLPN-filterfor controlling the “punch” while theMid-EQ’s4 kHzdip-filtercan be used to reduce the sometimes aggressive sound of a horn system. TheHi-EQallows increasing the “clarity” depending on the desired degree of brilliance.

Its excellent dynamic range of more than 117dB, the extremely low noise level and the outstanding price/ performance ratio makes the PowerMax230 Controller an advantageous alternative to conventional crossover and controller solutions – even in the critical field of permanent installation.
