Dushanbe venue upgrades with Martin Audio
- Details
The work was carried out by the manufacturer’s long-term distribution partners, Latvian-based A-T Trade Music. According to the company’s sound and stage equipment project engineer, Imants Cīrulis, they had been invited to develop an integrated but adaptable solution by their Tajikistan dealer.
“Prior to this, the system could only be used for conferences and meetings rather than classical, pop and traditional music concerts and other events which now take place,” he explaines.
Of the choice of PA he says: “The client wanted a system that would be useful for this hall as well as for open-air events. WPC was the best choice for this.”
The system is optimised for two-box resolution, and is hung eight elements per side. The speakers are suspended from two points, thus meeting the requirement for quick removal, to enable easy redeployment at outdoor events or other places.
At the same time, eight SX218 subs have been placed under the stage in specially built chambers with excellent sound isolation (two subs per chamber). “There is no sense on stage that there are speakers immediately under the feet,” confirms the designer.
Six iK42 multi-channel amps have been assigned to drive WPC and SX218 (three amplifiers per side), while the iK81 powers eight Martin Audio LE200 wedges in bi-amped mode (two LE200 per input channel).
In addition to the PA, the sound system includes digital mixing, stage monitors, microphones, wireless microphones and in-ear monitors, rigging and cabling.
“The concert hall has a very interesting configuration,” Cirulis continues. “Its special feature is a very deep [11m] balcony that occupies one third of the hall. Calculation of speaker positioning using the [Martin Audio] DISPLAY software showed good parameters under the balcony without the use of delay lines - and this also proved to be true in practice. The sound pressure, clarity and resolution are amazing anywhere in the hall - from the front to the back row of seats.”
Also forming part of the installation are a pair each of Martin Audio CDD-LIVE12/CSX-LIVE118 subs. These are primarily used for side-fills on stage, but it is expected that this acoustic system will also be used for small presentations and events in the hall lobby.
