A new food culture conquers the world: food trucks are becoming increasingly popular and provide us with juicy burgers, spicy burritos or crispy tacos on festivals, at events or street parties. Listening to music or a radio programme is not only a pleasant distraction for customers waiting in line. Nowadays, the comprehensive catering concept of food truckers includes more and more suitable music. The PA system for 4-wheeled street food catering has got to meet the very complex requirements of mobile applications. Robust, weatherproof speaker systems ESP-215/WS which are suitable for outdoor applications provide the required high-quality music for guests. Each of the 2-way system is equipped with a stainless steel mounting bracket and can flexibly be aligned to the required area. The class D mixing amplifier PA-803DAP with a power rating of 1 x 30 W is used as power amplifier. Thanks to its fanless cooling concept, compact dimensions and a simple operation, it is particularly suitable for mobile applications. An integrated MP3 player can be used for music reproduction via USB interface or SDHC card slot. The features also include an FM/DAB+ tuner and Bluetooth interface. If required, additional connections for microphones or external audio players are also available.
