Powered speaker with LEDs
ALTO PROFESSIONAL SPECTRUM PA is a sound system designed for those who want to stand out during performances, not only for the audio, but also for the visual impact and the quick setup. Based on a bi-amplified vertical speaker with a peak power of 200W, equipped with 3 x 6.5” woofers (130W) and a 1” neodymium tweeter (70W) capable of covering a frequency range from 65Hz to 20kHz, ALTO PROFESSIONAL SPECTRUM PA includes a true 3-channel mixer on the back, with 2 mono Mic/Line channels on Combo connectors (XLR/¼” Jack) and one stereo channel with RCA and mini-jack TRS inputs. What makes the difference are the two vertical front bars consisting of RGB LEDs programmable via three potentiometers and configurable in 5 different operating modes:
- Mood: To illuminate the event with fixed light
- Meter: To emulate a LED meter that extends vertically according to the intensity of the music
- Mix: To vary the color of the light bars according to the frequency content of the reproduced audio (red for low, green for mid, and blue for high)
- Pulse: To emit light pulses in the color set with the "Color Select" potentiometer and with the brightness assigned via Brightness
- Party: Which generates different light effects according to the adjustments of the other potentiometers.
Another feature of the ALTO PROFESSIONAL SPECTRUM PA speaker is wireless connectivity via the Bluetooth standard (A2DP) for both input signals, i.e., from tablets, computers, or smartphones, and for cascading, including stereo link between two speakers. The amplifier has overheating protection and a particular limiting system that optimizes the audio signal even if the input level is exceeded. The speaker can be installed on standard stands thanks to the 35mm hole on the base, has handles for easier transport, and an XLR output for cascading.
