Alto Professional TS408 Overview

Compact, lightweight, and designed for reliability, the TS408 2000W Active Loudspeaker from Alto Professional is a versatile 2-way loudspeaker that delivers potent, room-filling sound for nearly any application.

The TS408 features two combo XLR-1/4" balanced inputs with an XLR output for your final mix or for linking directly to a second loudspeaker. An onboard mixer makes dialing in the perfect performance a cinch, but further options are provided by the free Alto App to remotely adjust any settings, including custom 5-band EQ presets and three DSP speaker modes, with instant recall ability. The loudspeaker even comes with flexible mounting options for meeting any application demand, whether they require freestanding placement, wedge monitor use, pole socket mounting, or even flown rigging.

Will it provide 48V phantom power to a plugged-in microphone?
Asked by: Yigang
The Alto Professional TS408 TrueSonic 4 Series 2000W 8" 2-Way Active Loudspeaker with Bluetooth, does not provide +48v phantom power for condenser microphones. If you use a microphone that requires +48V of phantom power, connect it to an external phantom power supply or mixer, before connecting it to the loudspeaker.
