  • Alto Spectrum Portable PA System with Dual LED lighting

    The Spectrum PA from Alto Professional is a portable 2-way, 200W bi-amplified PA system with wireless Bluetooth convenience and built-in dual LED lighting. It has three 6 ½" woofers and a 1" high-frequency compression driver, and can be utilized in small-to medium-sized events where top-quality Karaoke/PA sound and lighting effects are needed such as for weddings, coffee houses, recitals, and more.

    It features a frequency range from 65 Hz to 20 kHz, and the internal amplifier is divided up so 130W goes to the woofers, and 70W goes to the tweeter. Furthermore, the built-in 5-mode LED lighting array sets Spectrum PA apart from everything else. There are 38 tri-color (red-green-blue) high-intensity LEDs with a control knob for color selection, and RGB preview, and also a brightness knob.

    Audio connections include the following: Two combination input XLR-1/4", a 1/8" TRS stereo input, an RCA (line-level) stereo input pair; an XLR link output; and an AC power connection. Alto professional's Spectrum PA is lightweight (23 lbs), easily transportable, and easy-to-set up.
