Solution

For the wide-ranging school premises, good speech intelligibility is top priority. For the different rooms, we have used 2-way speakers WALL-05T/SW and WALL-04T/WS. The combination of bass-midrange speakers and dome tweeters ensures clear announcements. For the school's own gym, we have additionally used sound projectors RL-1EN and ball-proof speakers PAB-52WP/WS in order to guarantee a continuous PA application.

A total of 3 microphone stations PA-6000RC can be used for making announcements into either each zone individually or a selected number of zones. With the MAESTRO-1, it is also possible to make announcements via the telephone system. The power amplifier PA-2240 and a 6-zone mono mixing amplifier PA-6240 perfectly supply each of the PA zones.

The digital message and timer insertion PA-1120DMT which is integrated in the amplifier allows you to create individual break signals and break times. In order to ensure announcements in case of an emergency, the system is connected to 24 V emergency power supply PA-24ESP.

The PA system is completed by a 12/2 full range system for the assembly hall. Two high-performance speaker systems PAB‑12WP/SW (200 W) ensure an excellent sound reproduction on smaller stages. The highperformance class D amplifier STA-1000D, preamplifier PA-1414MX and the versatile CD and MP3 player CD-114/BT have also been added to the system.

“With the PAB-12WP/SW, the product range of IMG Stage Line now includes a weatherproof (IP45) 12/2 speaker system. It is available at an attractive price yet has plenty to offer. The speaker system provides impressive test results and a great sound experience. Overall, the PAB-12WP/SW and the PAB-120WP/SW can definitely be recommended for purchase, especially if you need a solid 12/2 speaker system which is able to still operate effectively even under difficult boundary conditions.” Test author Anselm Goertz

“[...] for users and service providers who are often working at outdoor events or have to attend permanent outdoor applications, the PAB-12WP/SW is definitely worth considering ... open-air event in the Rhineland area, Germany ... continuous rain, from light drizzle to downpour ... despite plenty of water, even from every angle, the PAB-12WP/SW provided a smooth performance throughout the 6-hour test.
