Technology, design, and power. Each speaker in the Black series delivers 2400W peak power (1200W continuous) in class D. Designed and calibrated in the USA, all speakers in the line feature a user-programmable integrated DSP, dedicated crossover, and overheating protection. Regarding connections, Alto Professional's Black series speakers have a 2-channel mixer with mic/line inputs on combo connectors, capable of accepting both XLR and ¼" Jack connectors, and a balanced XLR output. In addition to the three speakers, which share the same characteristics but differ in woofer size (10", 12", and 15"), the Black series also includes two powered subwoofers, also with the same 2400W peak power generated by a class D amplifier, and 15" and 18" cones.
WIRELESS CONNECTIVITY
Volume settings, detailed EQ and compressor adjustments, delay for aligning multiple speakers placed at a distance, etc. Thanks to wireless integration and the Alto Professional app for iPad and iPhone, you can manage and adapt these speakers to any situation, play music from your iOS device, etc.
DESIGNED WITH ATTENTION TO DETAIL
Alto Professional Black series speakers feature perfectly designed and calibrated components for powerful sound and essential efficiency in professional use. Each speaker has been optimized to cover a 90°x60° range with a wide frequency range. From conference rooms to rehearsal rooms, from amphitheaters to sports arenas, from discotheques to outdoor events, the Black series will provide the right sound for any occasion.
WHERE AND HOW YOU WANT IT
The powered speakers of the Black series can be used in any location, thanks to the various mounting and positioning options available, from iron-reinforced rubber feet for ground placement to the 6 embedded M10 nuts for ceiling placement, up to the standard 35mm hole for stand insertion. The cabinet is constructed using sturdy 18mm thick multi-ply wood, treated with a scratch-resistant black finish. Despite their robustness, the speakers in the Black line remain easily transportable, thanks to their light weight and convenient recessed handles in the cabinet. Don't worry about where and how you place them; thanks to wireless remote control via iPhone and iPad, you can manage the settings of these speakers comfortably seated in a corner of the room.
