Alfa Audio Introduces Alfa Ecoustics

Alfa Audio has installed the first ever “Alfa Ecoustics” electronic acoustic enhancement system into Fredericia’s latest live venue, Tøjhuset. Using 30 x EM Acoustics EMS-51 loudspeakers, a tc electronic “brain”, and DPA microphones, Tøjhuset represents the first formal deployment of the Alfa Ecoustics system conceived by Alfa Audio’s Lars Frederiksen.
The system was required to put some reverb back into the venue as it had recently been converted from a
dedicated classical music venue into a live music venue for all genres.
The acoustics were deliberately dampened to suit the purposes of rock club, which meant, of course, that the acoustics were no longer suited to classical music. At the heart of the system are three tc electronics System 6000 reverb and signal processing platforms which receive the audio signal from several DPA 4015C compact, wide cardioid microphones via a DAD AX32 AD/DA converter. The reverb signals are then delivered into 32 channels of d&b amplification and output through 30 EM Acoustics EMS-51 ultra-compact passive fill speakers and two i-8 subs. The speakers are distributed over and around the audience area, flown from the impressive wooden beams that form part of the structure of the original building, whilst the rest of the equipment (apart from the microphones) is in a rack locked away behind the stage. A panel at the side of the stage offers basic system control and preset selection.

“The system is delivered tuned with a number of fixed presets for different applications,” continued Frederiksen. “The user simply has to select the appropriate preset by the touch of a single button, and it’s good to go.”
