Cinema Room at TV Nova

Great sound for small presentations and film projections

If you want to fit meetings, trainings, presentations and film projections in one hall, you need to know how room acoustics works. Integrate such a place with expensive speakers is not enough. You will probably regret it.

When the management of TV Nova wanted to reconstruct the cinema hall, we analyzed and measured the space as soon as possible.


What did we discover?

Projection system and sound system were obsolete and did not match the current standards. The acoustic tiles did not match the volume of the hall and there was a flutter echo created.


How did we solve those problems?

With the combination of different acoustic tiles and materials, we have reached an equal acoustic absorption in all areas of the space. Behind the perforated projection screen, a mineral wool is installed, side and back walls are covered with a perforated plasterboard, supsended ceiling combines two different types of absorptive acoustic panels.

  • The reverberation time is homogeneous across the room.
  • The seats are virtually equal in terms of listening.
  • We left the speech frequency band slightly emphasized, so that the speaker is well understood without having to raise his voice.

The design of wall tiles and suspend ceiling has been made with regard to the simplicity of installation – minimition of acoustic cuts and an easy installation of cabling.

Technical Specification

Sound System

L-Acoustics front speaker set including a subwoofer was preserved and moved behind the projection area which required an installation of a new and larger perforated screen. We replaced inadequate surround speakers with newly installed L-Acoustics 5XT. There are also new L‑Acoustics LA4X 4-channel DSP amplifiers optimized for the whole speaker set.

Marantz AV8802A AV processor with Audyssey adaptive system provides dynamic equalization and physiological volume control following the rest of the audio chain and the space parameters.


For AV system control, there is new Extron button panel with HDMI input for connecting user devices. For alternative content, a motorized pull-out stand for the existing Sony Bravia LCD display is installed in front of the projection screen.

Projection Cabin

In the projection cabin, there is a new technological rack, ideally high for placing a new NEC NP-PX803UL laser projector (8000 ANSI lm, 1920×1200) to an optimal position and for all other equipment, including a new universal BD player with RS 232 control.
