The integrated and easy-to-use digital signal processor (DSP) allows you to customize the loudspeaker for a number of applications including DJ, FOH, Monitor, and Speech presets. Additionally, ±10 dB of treble and bass control allows you to further tailor the sound and compensate for room anomalies. Location presets let you optimize performance for stand and bracket mounting as well as flown installations. The Air15 ships with a power cord.
