LEA Professional powers the audio of the Alfa performing arts theater

Dante Connect series amplifiers LEA Professional respond to the audio needs of this well-known theater in the Czech Republic.

Located in the Czech city of Pilsen, he Alfa theater specializes in the performing arts of puppetry. To meet the audio needs in your busy schedule, those in charge have updated their sound system, according to the project designed by AudioMaster CZ, in collaboration with Audio Kropik.

How do you explain Jan Zvánovec, project manager at Audio Kropik, “the theater's sound engineer was having major problems with his existing system. We went to see the facility and discovered that they had speakers that didn't work and old amplifiers that were deteriorating and couldn't be repaired.. Simply, The system had reached the end of its useful life..

To meet the requirements of the Alfa theater and fit a limited budget, The Audio Kropik team began searching for the components and, as critical specification, high quality amplifiers, multichannel, ready for the audio network and that will provide the power and flexibility necessary for the installation's activity.

“I had not used amplifiers LEA Professional before, but they had all the features we were looking for and at a good price -adds Zvánovec-. Amplifier cloud technology, The built-in DSP and preset functions were also very interesting”.

The team upgraded the theater's audio system with a set of three series amplifiers Dante Connect from this manufacturer. Specifically, two amplifiers are used IS CS354D Four channels to power the top and bottom main speakers, left, right and center, and one IS CS704D to power the subwoofers.

The new system comprises a combination of nine compact speakers from the AE series of JBL Pro. A digital mixing console Yamaha DM2000, equipped with a Dante network card, communicates directly with LEA amplifiers via this audio network protocol.

“The Dante technology built into the amplifiers allows for an extremely simple connection between the mixing and technical rooms.. Everything worked from the first connection and we have a lot of flexibility for future updates - assures Zvánovec -. There is also no need for external speaker processors because everything is handled by the DSP built into the LEA amplifiers., saving time and money”.

The use of professional audio amplifiers with Integrated DSP has become standard practice for many AV system installers, as it frees up critical rack space and reduces system weight.

All inbound routing, tuning the room, Speaker tuning and limiting are built into the amplifier, so equipment racks are smaller, light and clean.

“All the connectors and features of the LEA amplifiers are very logically arranged and well designed; The manufacturer has created them with the installer in mind -Zvánovec emphasizes-. We create several presets and store them on the computers so that the customer can change the settings easily”.

The new audio system works even better than expected, as Zvánovec emphasizes, “not only because of the new speakers, but for the powerful and natural sound of LEA amplifiers, and that is why we have added them as a supplier for future projects”.
