Modern restaurant PA – LD Systems in the Amza Restaurant

Open – that’s how you might describe the Amza restaurant in Sibiu, Romania, in just one word. Over a hundred tables in a large, spacious dining area, an open kitchen, floor-to-ceiling windows, and lots of wood and plants. Amza’s operators have created a thoroughly modern restaurant concept. Their AV service provider, SET-UP, chose a combination of the LD Systems CURV 500 and DQOR speaker series to provide sound for the restaurant’s acoustically challenging environment.

“The end customer wanted a sound system that sounded like hi-fi and also offered sufficient power in the bass range for occasional lounge events with a DJ in addition to normal restaurant operations,” explains SET-UP CEO Grunca Ovidiu. With an indoor floor area of around 25 x 30 metres, the open room design requires precise selection and alignment of the speakers – not least because the restaurant has a lot of sound-reflecting surfaces. “Consequently, it was important to have the vertical sound dispersion under control,” says Grunca Ovidiu.

“The scalable CURV 500 satellites, with their narrow vertical dispersion, cause fewer reflections on the ceiling and floor.”

Precise sound dispersion

For the indoor area, SET-UP’s long-time LD Systems users were confident of the advantages of the CURV 500 array system in this respect: “The scalable CURV 500 satellites, with their narrow vertical dispersion, cause fewer reflections on the ceiling and floor,” says Grunca Ovidiu. “This means more direct sound, and a better sound, than when using conventional installation speakers.”

The team distributed a total of 16 arrays, each with three S2 array satellites, in the restaurant’s dining area, supplemented by two individual S2s in the restrooms. The desired low-frequency pressure is provided by 16 CURV 500 I SUB 10″ bass reflex subwoofers, which, thanks to their slim profile, could be elegantly mounted in groups of two on the side walls. The entire speaker setup is powered by several CURV 500 I AMP 4-channel Class-D installation power amplifiers.

“The DQOR series continues to impress us with its combination of consistent frequency reproduction, IP65 weather resistance and modern design.”

Flexible control

In the outdoor area on the terrace, eight DQOR 8 T IP65 installation speakers with 100V technology ensure optimum sound coverage via an IPA 424 T 4-channel DSP installation power amplifier. “The DQOR series continues to impress us with its combination of consistent frequency reproduction, IP65 weather resistance and modern design,” says Grunca Ovidiu. In addition to smartphones and tablets, an LD Systems RSMP universal media player is used for convenient playback of internet radio stations. The audio content is distributed to the two zones – indoor and outdoor – including source selection and volume control via the ZONE X 1208 DSP audio matrix and a tablet control interface specially programmed for Amza staff.
