Located in the center of the Czech city of Jablonec nad Nisou, the city’s historic theatre stands as one of its most treasured cultural landmarks. Completed in 1907, the building reflects the elegance of early 20th-century Art Nouveau design and has served as a gathering place for the performing arts for more than a century. While the venue doesn’t have a resident ensemble, each season brings more than 200 visiting performances spanning drama, opera, ballet, concerts, and children’s productions. Renowned Czech companies and touring artists regularly appear here, ensuring a diverse and dynamic cultural calendar.
Beyond its programming, the theatre itself is part of the experience. The interior retains an exceptional array of original Art Nouveau decorative elements, from lighting fixtures to ornamental detailing, creating an atmosphere that transports audiences to another era.
When some of the existing AV systems began to fail, theatre staff contacted Matěj Sborový, project manager at AudioMaster CZ, to design and deliver a comprehensive AV solution to elevate the venue’s operational efficiency and entertainment capabilities. AudioMaster, in turn, partnered with Michal Blazek Profisound to perform the installation.
“The theatre has a pretty extensive audio system,” said Sborový. “However, almost everything in the old system needed to be replaced. LEA amplifiers were my first choice to ensure exceptional audio quality.”
Sborový selected Connect Series 702D and Connect Series 354D amplifiers to power the theatre’s loudspeakers. The IoT-enabled 2-channel 702D delivers 700 watts per channel, while the 4-channel 354D delivers 350 watts per channel. Both models support Hi-Z (70V or 100V) and Lo-Z, selectable by channel, eliminating the need for separate amplifiers to handle different speaker impedances and streamlining installations and reducing equipment costs. Connect Series amplifiers also include a 96kHz DSP standard in all models and offer a range of benefits that significantly enhance audio performance and system versatility. Dante-enabled models like the 702D and 354D include 96kHz-capable Dante and AES67 connectivity, simplifying system installation with scalable, high-resolution audio over IP (AoIP).
The Connect Series delivers an industry-first professional amplifier family featuring cloud connectivity, a revolutionary advancement, and a significant benefit for anyone maintaining the systems. With LEA Cloud, AV teams can remotely control and monitor the amplifiers regardless of location or time of day, and with no subscription model or hidden costs, it’s completely free to use.
“The LEA Cloud service is a tremendous benefit for me and the theatre. Being able to log in from anywhere and troubleshoot issues or make necessary adjustments is a game-changer,” said Sborový. “There’s very little I can’t access remotely, which ultimately saves my customers money because I don’t have to dispatch a local technician or drive to the site.”
The Jablonec nad Nisou City Theatre has a full calendar of upcoming events. Thanks to the audio upgrades, every seat in the theatre now offers an outstanding experience, and visiting ensembles have praised the clean, beautiful sound.
“LEA amplifiers just work,” said Sborový. “The state-of-the-art connectivity and pristine sound make these amplifiers essential for the theatre. I’ve been thoroughly impressed with every aspect of LEA.”
