Following the upgrade of the lighting system on the Small Stage, the theatre has completed the second phase of its modernization project. The "Pera Dobrinović" stage now boasts a state-of-the-art stage management system and an advanced sound system that delivers exceptional performance.
Enhanced Sound System
A cutting-edge d&b audiotechnik sound system has been installed to support a wide range of events, including ballet and theatre performances, musical programs, and film screenings. The system features:
- d&b 24S-D point source speakers: Positioned vertically (left and right) and horizontally (center), these speakers offer 110° x 55° sound coverage with a maximum sound pressure of 137dB. The rotatable horn design allows flexible installation.
- d&b D40 amplifier: A 4-channel DSP amplifier delivering stable power output of 4 x 2400W.
- d&b Y-SUB subwoofers: These cardioid-pattern subwoofers provide precise bass reproduction with a sound pressure of 134dB, reducing unwanted stage reflections.
- d&b MAX2 monitors and 12S-D speakers: Clear stage monitoring and consistent space-wide sound coverage ensure a flawless audio experience.
The system is centrally managed using the d&b ArrayCalc software, enabling precise simulation and design of sound parameters tailored to the venue's specifications. After installation, custom presets and acoustic adjustments were fine-tuned for optimal performance.
Sophisticated Sound Processing
At the core of the sound processing setup are DiGiCo S21 digital audio consoles with advanced routing and audio effect capabilities, including EQ, reverb, compression, and delay. These consoles feature dual touchscreens and motorized faders for intuitive control. Audio signals are seamlessly transmitted via the MADI protocol to a DiGiCo D-Rack stage box, connected through Cat5a network cables.
For external broadcasting, the system includes 8-channel microphone/line splitters with galvanic isolation to ensure interference-free transmission to radio and TV teams.
Wireless and Wired Microphones
The stage is equipped with a comprehensive microphone setup, including:
- Audix OM5 dynamic handheld microphones and DPA 4488-DC-R-F00 headset microphones** for precise vocal pickup.
- DPA 6060-OC-U-F00 lavalier microphones for discreet applications.
- DPA ST2011C and KIT-4099-DC-10C instrument microphones, ensuring versatile and professional sound reproduction.
- DPA 2028-B-B01 supercardioid vocal microphones for clear, transparent vocals during live performances.
The wireless microphone system is supported by Audix receivers, splitters and antennas, providing reliable stage coverage with automatic IR frequency adjustments.
Stage Management and Communication
A two-channel stage management system has been installed to streamline backstage operations. This system facilitates:
- real-time communication among technical staff during performances,
- performer notifications in dressing rooms via a paging system and
- playback of performance audio for stage crew coordination.
Video Integration
PTZ cameras with 3G-SDI output and 20x optical zoom provide enhanced monitoring of main stage events. These are connected to a video mixer with multiple input options and streaming capabilities, enabling seamless content creation and live streaming via USB 3.0.
Professional Installation and Training
All microphone, speaker and antenna installations use halogen-free cables with shielding to minimize RF interference and crosstalk. Post-installation, the technical staff received training on managing the audio consoles and stage management system, ensuring they are fully equipped to operate the new technology.
With these upgrades, the Small Stage of the Serbian National Theatre now offers cutting-edge capabilities that meet the highest standards of modern performance venues, elevating every production to new heights.
