The National Bank of Greece in Athens, housed in a neoclassical structure constructed around 1890, recently commissioned Athens-based Automation Broadcasting Audio Security (A.B.A.S.) to design and install a new sound reinforcement system headed by Community Professional loudspeakers to serve cultural events such as exhibitions, presentations and meetings.
“The beautiful interior is highly reverberant due to all its surfaces being very reflective, combined with the height of the room which reaches 16 meters,” explains Kostas Drosos of A.B.A.S. “We needed a loudspeaker which delivered the audio quality required within a narrow vertical and wide horizontal dispersion pattern.
“To meet these parameters we chose Community ENTASYS ENT220 column line array loudspeakers,” he continues. “With twenty 80 mm long excursion mylar LF drivers and four 3-element HF Compact Ribbon Emulators per enclosure, they gave precisely the well-behaved directivity control we needed.”
Complete and even coverage of the room was achieved with just four ENT220s, Drosos notes, adding, “Their slim profile also meant they were very discreet and aesthetically pleasing.”
Each loudspeaker is driven by a separate amplifier to provide different sound levels required for the front and the mid/back spaces. Monacor amplifiers from Germany were selected for their powerful built-in processing for loudspeaker equalization. With Crestron control, the system can be operated wirelessly from an iPad.
“The new audio system provides superbly intelligibility and coverage,” concludes Drosos. “It sounds very natural and listeners do not hear any change in volume throughout the room, allowing them to completely relax and focus on the event they are attending.”
