Product code: QSC AD-S282H
Detailed Description
Features
- Contemporary style, weather-resistant enclosure and components – ideal for a wide range of applications.
- Dual 8-inch, 2-way system – in a lightweight, multipurpose enclosure featuring a heavy duty, powder coated aluminum grill.
- Versatile mounting options – The included yoke mount bracket can be used for mounting and aiming the system in vertical or horizontal orientations. Provision for optional Omni-mount™ bracket is built in.
- Advanced Directivity™ rotatable waveguide – (90° × 60°) enables the loudspeaker to deliver accurately focused sound, regardless of the enclosure’s mounted orientation.
- Low impedance and transformer versions – Standard 8 ohm system is selectable for passive or bi-amp operation while the AD-S282HT transformer version provides taps for both 70V and 100V distributed system use.
