Alto | PRO | Alto Black 15 - Alto Professional

15" 2-WAY 2400 WATT LOUDSPEAKER WITH
WIRELESS CONNECTIVITY
Designed and tuned in the USA, Black Series
2-way active loudspeakers offer more power,
more agility, and more intelligence than any other
speaker in their class.
Power for the Black 15 comes from an efficient Class D amplifier capable of
producing 1200 Watts of continuous power, with a dynamic/peak power rating
of 2400 Watts. The optimized HF waveguide provides an effective 90° x 60°
coverage field.
The cabinet features sturdy plywood construction with an anti-scuff coating. The
steel grille is finished in a professional-grade powder coating. Custom-molded
handles allow easy transport. Steel-reinforced rubber feet provide excellent
stability. The Black 15 offers feet on two sides, for vertical or horizontal use.
A pole-mount socket (35mm) is fitted into every model. Standard M10 rigging
points allow the Black 15 to be flown. The illuminated logo nameplate can be
switched off for more discreet installations.
The Black 15 features two XLR+1/4" combo inputs offering individual level
controls, and Input 1 is equipped with a Mic/Line switch. The single XLR Mix
