Solution

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 truck owners more and more includes suitable music. PA systems for 4-wheeled street food catering have to meet very complex requirements of mobile applications.

Robust, weatherproof speaker systems ESP-215/WS, which are suitable for outdoor applications, provide the appropriate high-quality sound for guests. The 2-way systems are supplied with stainless steel mounting brackets and can be flexibly 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 a fanless cooling concept, compact size 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.
