Inter-M WS50T Professional Loudspeakers

The Inter-M WS50T Wall Speakers boast a truly elegant yet powerful design that delivers a stylish look where space is at a premium. The speakers can be used in various applications from small-sized venues to mid/large-sized venues. They particularly fit in facilities that require high-quality background/foreground music such as cafes, bars and restaurants, hotel lobbies and retail stores etc. 

Thanks to a 2-way asymmetric horn, the WS50T's have a wide dispersion of sound ensuring maximum coverage across the whole establishment. They also feature a slightly angled tweeter that projects sound downwards towards the most important areas such as the bar and dancefloors, instead of upwards towards the ceiling/dead zones. 

Inter-M WS-15T Speaker Dispersion and Distance

The Inter-M WS50T loudspeakers are also IP54 rated so can also be installed outdoors in areas such as beer gardens, smoking shelters, outside eating areas and under canopies etc. 

Inter-M PA240A 240W Mixer Amplifier

The Inter-M PA240A is a desktop mixer amplifier designed to deliver high-end music playback in any commercial or public environment such as restaurants, bars, and retail stores etc. 

Featuring six inputs (five mic or line level) the PA240A can stream music from smartphones, tablets, CD players, laptops or any other external media device. You can also connect a desktop or handheld microphone perfect for announcements, last calls, pub quizzes or emergency instructions etc.

The Inter-M PA240A has a five-way output zone selector meaning you can switch a run of speakers on or off when they are not in use.

The PA240A has Class-D amplification so operates at extremely low temperatures and extremely low in running costs. Class-D components are also extremely light making this amplifier suitable for sitting on a desk/counter. An optional rack kit can also be added if you need it mounting into a 19" rack cabinet.
