AV Equipment of Hotel Danube


In the hotel premises, you can find spaces with a variety of uses from meeting rooms, through social spaces to a wellness center. For AV technology designers, it is a pleasent exercise for their wide range of skills. That is the way it was in Hotel Danube, where we have designed AV equipment.


What spaces were part of the project?

  • Hotel lobby,
  • foyer,
  • meeting rooms,
  • conference hall with mobile partitions and control room,
  • wellness center (gym, swimming pool, whirpool, sauna, massage saloon, fitness, changing rooms),
  • halls and other common areas.

For social and common areas together with wellness center, we have designed multi-zone ambient sound system consisting of speakers built in the ceiling. Conference spaces are going to be equipped with a viewing technology, either projectors with screens, or LCD displays. Large conference hall is going to be equipped with interpretation system and there are going to be installed IP dome cameras for image preview of the hall.


What does our AV equipment enable?

  • AV equipment of the conference hall was designed in order to allow the whole space to be operated at the same time while providing AV equipment for spaces separated with mobile partitions.
  • We have divided social areas and the wellness center into the separate zones and thanks to that you can control playlists and its loudness from a control panel at the reception.

Technical Specification

Conference Hall – Projections

Large conference hall is going to be equipped with a central projector with the possibility to divide to the hall into three smaller identical spaces. In a default mode, the central Epson EB-2250U projector of 1920 × 1200 resolution and 4000 ANSI lm output power project onto a motorized screen eith the width of 3.5 meters. The second identical projector is used as complementary or for longitudinal orientation of the projection in a split mode. In this case, a screen of 3m width is used.

IP dome cameras Dahua IPC-HDBW2300RP-Z are also part of the AV system. They ensure the transfer of the image preview from the hall. Sound system in the hall consists of JBL Control 14C/T two-way full-range ceiling loudspeakers. For people who present, we have designed a wireless microphone system.

Extron touch control panel is going to ease operations, and for external sources there are going to be installed floor and table connection points.

Conference Hall – Language Distribution and Conference System

BOSCH interpreting system is going to consist of four 6-channel interpreter desks with a loudspeaker providing listening and calling functions for interpreters. In the control room, there are going to be installed BOSCH INT-TX04 4-channel IR transmitter and BOSCH LBB 3422/10 symmetrical audio input and a module of interpreters.

In the conference hall, there is going to be available BOSCH conference system. For communication, we have designed devices for wireless conference discussion (4 participants and 1 chairman) with accumulators and microphones, these devices are going to be connected to a wireless access point. Also, we are going to install a radiator for infrared signal distribution throughout the conference venue, enabling delegates to listen to the proceedings by means of personal pocket receivers. At total, 150 pieces of these receivers and headphones are going to be available.

Control Room – AV Technology

In the rack, there is going to be installed an audio signal processor BSS Audio BLU 100 with 3 BSS Audio BLU BOB1 break-out-box extender and 2 BSS Audio BLU BIB break-in-box extenders. Also, there are going to be installed 2 modular audio systems and a quad-channel power amplifier AUDAC, Oppo UDP-203 4K Ultra HD Blu-ray player and Apple TV. Extron receivers, transmitters and a matrix switcher are going to be used for signal distribution. For preview, there are going to be used three FullHD diplays and Klipsch R-15PM power monitor speakers.

Social and Common Areas and Wellness center

Social, common areas and wellness center are going to be equipped with multi-zone ambient sound system consisting of JBL Control 14C/T two-way full-range ceiling loudspeakers. Zoning is solved by the powered branches leading into individual areas. Thanks to the Extron scaling presentation matrix switcher, that controls the entire zone sound system, it is possible to group individual power branches together without any physical change in the system.
