Spectrum PA is a portable PA system with built-in dual LED lighting arrays that fulfills your requirements of delivering great performance sound, exciting lighting effects and wireless Bluetooth® convenience for both musical acts and Karaoke performances.

Spectrum PA is a 2-way 200-watt bi-amplified system housed in a very trim enclosure measuring just 8.4 x 29.2 x 10.1” (212 x 740 x 257mm) HWD. The drive units are three 6 ½” (165mm) woofers and a 1” (25mm) high-frequency compression driver, which span the full musical frequency range from 65-20kHz. Its internal amplifier is divided 130 watts to the woofers and 70 watts to the tweeter. The system has thermal and dynamic overload protection, so the sound is always clean and clear no matter how hard it’s pushed.

However, it’s the built-in 5-mode LED lighting array that really sets Spectrum PA apart from everything else. There are countless small- to medium-sized events where top-quality Karaoke/PA sound and lighting effects are needed: weddings, karaoke contests, coffee house performances, recitals and more. In every one of these situations, expensive, complicated stacks of equipment and lighting are both inappropriate and unnecessary. Alto Professional’s Spectrum PA fulfills all these requirements with one easily-transportable, easy-to-set up unit.
