Lancaster-based company Low Fold Audio. carried out the installation in the college theatre, which is used for a range of activities including presentations, full theatre and live music shows.
Two Fohhn AT-50 loudspeakers have been flown from the lighting bar to form the main PA system, with four AT-09 speakers fixed to the wall either side of the stage for use as in-fills, positioned to cover the balcony seating and the first few rows of the main auditorium. A single Fohhn D-2.1500 DSP-controlled Class D amplifier has been configured to run the AT-50 loudspeakers, with a Fohhn D2.750 amplifier handling the four AT-09s.
The system has been set up using Fohhn Audio Soft software, which gives remote access, from a central location, to a range of DSP functions for tailoring the room sound, balancing the speakers and adding subtle limiting as required.
Low Fold's Mark Burford comments, "We have been very pleased with the overall results. The 15" LF units in the AT-50s provide plenty of tight controlled bass, while the AT-09s fill in the balcony areas superbly, with very little difference of tone or coverage discernable as you move around the theatre. All in all, a balanced clear sound has been achieved throughout the auditorium."
"We are very happy with our new Fohhn system" says Stavros Kokkinos, head of music at Concord College. "It sounds like a Hi-Fi but in an auditorium. Crisp, accurate and with enough punch it delivers the results we want with music ranging from classical to the students' heavy metal bands. The added benefit of lockable, tamper proof, remote DSP settings is a big bonus too and invaluable to an institution like ours."
Fohhn UK distributor Systems Workshop supplied the loudspeaker systems.
