Helsinki, Finland (January 8, 2010)--Finland's first installation of JBL Professional's new CBT100LA column enclosures has taken place in the Latokartano Sports Hall in Helsinki.

Run by the Physical Exercise department of the City of Helsinki Sports Administration, the Latokartano Sports Hall consists of two large areas, which can be combined into a single, larger space. Schools and sports clubs use the space primarily for volleyball, floor ball, football and tennis. Krautsuk, who set up Workland back in 1994, selected the CBT Series.

The Sports Administration issued the contract for the technical fit-out once the new building superstructure was complete. "Although the JBL solution was not originally specified, Workland turned to the earlier successful collaborations we have enjoyed with JBL once this became available," commented Ari Hildén of Harman Professional distributor, Studiotec. "Having seen the visuals and specifications [of the CBT100LA], I was certain that this was the correct choice. Having heard the system, I have to admit that its performance is definitely superior to the alternative model."

Krautsuk designed two transportable systems, which come into play when the partition curtain divides the room into two independent spaces. Four CBT100 enclosures have been installed down the long walls (so that one side runs silent, and the other with music). A Crown XLS 602 amplifier feeds two speakers from Channel 1 and two from Channel 2, while the two sections are controlled independently via a Crown mixer.

As part of the CBT (Constant Bandwidth Technology) functionality, these speakers include a switch that selects either long- or mid-throw dispersion patterns. Also standard for the series are "Music" and "Voice" settings (the latter featuring a vocal-presence boost) and Dynamic SonicGuard overload protection circuitry, which combats distortion issues.
