      1. LOCATION LENDAVA



        1. GENERAL DESCRIPTION OF EQUIPMENT ON LOCATION LENDAVA


The subjects of the public tender for location Lendava is the purchase of mixing consoles and communication (talkback) equipment. The equipment will be installed in 1 radio on air studio, 2 production studios and 2 dedicated talk studios.

The studios are designated as:



  • MMR ONAIR – main on air studio

  • MMR POG01 – dedicated talk studio for MMR ONAIR

  • MMR MONTAZA – main production studio which can also be used as a spare on air studio

  • MMR POG02 – dedicated talk studio for MMR MONTAZA

  • MMR NOVINARSKA – secondary production studio

  • MMR-MCR – Lendava master control room

The mixing consoles must be in a modular form construction and consist of control surfaces, main DSP core units and audio I/O modules.

All equipment on location Lendava should be connected to 2 physical DSP core units as it can be seen on Lendava - Appendix 1.

All physical DSP cores, connection equipment and some I/O equipment (for audio computers, telephony…) will be installed in MMR-MCR. I/O equipment, directly attached to different studios, will be installed directly inside that studio.

Both physical DSP cores should be connected in the way that all inputs from both cores are available on every control unit (fader bay).


Provider should provide computer software for configuration, programming and operation of audio consoles, core (DSP) management and connectivity of DSP units and also software for displaying the console info and metering on PC display (as external screen).

Connections between all modules of the system and DSP cores spread over different studios should be implemented only with Cat 5/6 or optical cables.

The audio I/O modules should be noiseless because they will be installed inside different studios close to the microphones.

  • Audio level metering according to recommendation EBU R128

  • TFT, LCD or bar graph displays should allow measurement of the audio level on all inputs, outputs and audio buses.

  • Overloaded signal must be shown with warning signs on the instrument.

  • Mono compatibility indicator for stereo signal.

  • Auto mix mode for talk show applications.

  • Each physical DSP core must be capable of processing at least 24 fader channels simultaneously.

  • Power supplies should be fully redundant, with automatic changeover in case of failure.

      1. CONFIGURATION OF THE SYSTEMS (APPLIES TO ALL LOCATIONS)


The Contracting Authority will install the equipment to different locations and different studios therefore the installations will take place for a longer period. The configuration of the equipment should be done in 2 phases.

The first phase comprises the basic configuration according to the Contracting Authority’s requirements defined in chapter 3.2.

The second phase comprises the detailed configuration of the system and depends on the supplied equipment and will be defined between the Bidder and the Contracting Authority. The second phase will be carried out after some trial period that will not be longer than 5 months. Trial operation should reveal eventual irregularities in configuration or give some ideas for improvements. The Bidder should then - according to the findings in the test period, carry out the adequate adaptations.

Both phases of configuration should be included in the bid.
