SKOPJE, Macedonia – DT Kodi recently used AKG's DMM 4/2/2 digital automatic microphone mixer as part of a larger audio upgrade using gear from Harman Professional audio upgrade at the U.S. Embassy in Macedonia. The system – which also includes JBL loudspeakers, Crown amplifiers, dbx processors and additional AKG wireless products – will be used for sound reinforcement for the floor debates, conferences and entertainment.
The Embassy's technical department had been seeking a system that would be able to provide open conference, simultaneous interpretation, recording and some basic sound reinforcement. The system also needed to function virtually operator-free.
"When I saw the space, it was clear that it was much more than a conference hall," said DT Kodi's sales manager, Iko Daskalov. "Therefore we needed to propose a solution that would cover all technical requirements for a range of activities, including conferencing, round table discussions, lectures, meetings and press conferences. Further to that, in the afternoons the same hall is used as a media room by other Embassy personnel, which means the system undergoes a heavy duty cycle."
The three DMM 4/2/2 units are providing automated mixing of 12 AKG WMS 450 flexible wireless systems. Other WMS 4000 accessories included in the package were a central power supply, signal distribution and control of the wireless systems, with omnidirectional antennas placed in the conference hall. The DMM 4/2/2 feeds the system processor and digital IR system for simultaneous interpretation from DIS (Danish Interpretation Systems), while solid state recorders have also been supplied.
The DMM 4/2/2 has been designed with a mixing algorithm that gives it the flexibility to handle a variety of mixing applications. The system includes four microphone and two stereo AUX inputs per each DMM 4/2/2, intelligent mixing algorithms with a noise sensitive threshold to prevent accidental activation of input channels and a digital signal processor with a dbx compressor.
Each channel on the mixer offers switchable gain, switchable phantom power, and an incremental level control with peak hold display, and each system comes with an expansion connector that enables multiple mixers to be linked together for larger audio setups.
For sound reinforcement, the system's Harman components include dbx processors, Crown amplifiers and JBL speakers. For entertainment, a surround processor has been added with custom installation speakers and powered subwoofers from JBL. The gear was furnished via Harman Professional distributors, AVC in Skopje.
"The room had already been fitted with an LCD projector and large media display – so we integrated them in to the system and added HDMI distribution and signal conversion for further extension," said Daskalov. "The system required careful tuning, but once it was commissioned, the customer was impressed both with the performance and appearance of the design."
