Tbilisi, Republic of Georgia (March 23, 2017)—The Hard Rock Café is known the world over, and that omnipresence no doubt helped ready Tbilisi, the capital of the Republic of Georgia, for its own edition. Built in a former wine factory, the newly designed multi-level venue features a restaurant, several indoor and outdoor bar areas and a live performance stage—and a QSC system based around K Series powered loudspeakers, KLA Series powered line array loudspeakers, Acoustic Design loudspeakers, and CXD Series amplifiers, with all audio routing, management and processing controlled by the Q-Sys integrated system platform.

The Tbilisi Hard Rock Café project saw regional audio company Mifasi team up with QSC’s United Kingdom-based sales, export, design and installation partner, PAXT, as they had collaborated in the past. Working jointly on the design of the system, Mifasi handled the bulk of the installation, while PAXT oversaw the final tuning of the system prior to the venue opening. Together, they were tasked with providing sound for four different areas, all of which had to be linked to a sound system that could handle music playback and also transmit paging messages and safety announcements if required

Other crucial elements included speakers to cover the outdoor patio and indoor restaurant and café/bar areas, and outfitting a performance stage, which needed PA speakers and playback monitors for the musicians.

Mifasi and PAXT opted for passive two-way Acoustic Design AD-S6T and AD-S112sw subwoofers used in the indoor restaurant and café/bar areas. Because of their resistance to weather, Acoustic Design was also deployed on the outdoor terrace. There are 16 AD-S6Ts in total, and eight AD-S112sw subs, driven by twin CXD4.3Q amplifiers. The KLA line array loudspeaker system adorns the live stage, with the left and right channels each comprised of two KLA12 line-array elements with an added KLA181 subwoofer. Four K10 active loudspeakers are used on the stage as floor monitors for the live performers.

Overall control for the system is handled by the Q-Sys Integrated System Platform featuring a Core 110f processor. Martin noted, “Given the zoning and routing requirements at the Hard Rock Café, Q-Sys was the obvious choice. The Hard Rock Café’s own music playback system is connected to the Core 110f, which then handles all the routing and processing throughout the venue, and also controls the two CXD amps, which drive the passive AD speakers throughout the venue.”

Master control of all of the audio sources in the venue is available to the staff via the Q-Sys touchscreen interface, with live audio from the stage able to be routed anywhere in the venue. The system was pre-programmed by PAXT and Mifasi to automatically vary the levels of output during various business hours -- for example -- to automatically raise the speaker output as the venue fills up during the course of an evening and then to gradually become quieter again as closing time approaches.
