QSC AD-S802T AcousticDesign 8-Driver Column Surface Mount Speaker

The QSC AD-S802T 8-Driver Column Surface Mount Speaker is ideal for foreground and background applications with acoustically-challenging environments.

Get the best speech intelligibility out of your installed sound. The AD-S802T from QSC’s AcousticDesign series is an 8-driver column surface-mount loudspeaker ideal in foreground and background sound reinforcement situations utilizing 70/100V or 8Ω bypass configurations. Among its many features, Intrinsic Correction™ voicings can be deployed to optimize installation and performance. Additionally, the AD-S802T uses a Progressive Taper Topology™ (PTT) network to create a passive curvature of the array line, reducing side-lobing problems and equipping you for precise and consistent directivity control.

Maintain an accurate frequency response even in 70/100V applications. The AD-S802T’s low-loss, low-saturation 30W transformer offers selectable taps and incorporates a bypass for low impedance application and a rotary selector behind the sealed input cover plate. A removable wire sealing gland nut on the input cover plate enables direct cable attachments to a locking 4-pole Euro-style connector for added security of the wire terminations.

Myriad mounting options make the AD-S802T a versatile surface mount option for a wide variety of environments. Its unique pan/tilt mounting system offers multiple positioning locations, enabling you to keep the speaker close to the wall while achieving a downward tilt of up to -20°. The tilt section of the mount can also be removed when it’s not needed, letting you install the speaker even closer to the wall. The mount includes a zero pan locking screw in consideration of wind load conditions, as well as a shoulder eyebolt to provide a safety tether anchor point.

AcousticDesign speakers are free of obtrusive branding. They’re available in black or white, as well as paintable to match any décor. In addition to rugged ABS enclosures characteristic of AcousticDesign speakers, the AD-S802T boasts sealed input panel covers, weather-resistant powder-coated aluminum construction, and stainless steel hardware to exceed IEC60529 IP-54 ratings for dust and splash resistance.
