## Overview

The QSC AD-S402T is a high-performance 2.75" columnar surface mount loudspeaker designed for both indoor and outdoor applications. With its weather-resistant construction and advanced acoustic technology, it delivers consistent sound quality while ensuring durability and versatility in various settings.

## Description

The QSC AcousticDesign AD-S402T is a columnar array line consisting of four weather treated 2.75" transducers. Columnar loudspeakers are ideally suited for a wide variety of acoustically difficult applications where speech intelligibilty is a primary concern. The AcousticDesign Series offers integrators a premium quality installed sound solution where performance, consistent coverage, and aesthetics are paramount. Specifically designed to maintain a consistent tonal characteristic across the entire family in ceiling, surface, and pendant applications, the AcousticDesign Series allows integrators seamless transitions within blended installations. With rugged powder coated aluminum construction, stainless steel hardware, and sealed input panel cover, the AD-S402T is designed for indoor or outdoor use, exceeding IEC60529 IP-54 ratings for dust and splash resistance. A carefully crafted PTT (Progressive Taper Topology) network is utilized to create a passive curvature of the array line which greatly reduces side lobing, often problematic of straight array lines, resulting in precise and consistent directivity control. The accurate frequency response of the AD-S402T is maintained even in 70 / 100 V applications by use of a low-loss, low-saturation transformer with selectable taps, including a bypass for low impedance application, using a rotary selector located behind the sealed input cover plate. The input cover plate comes with an attached wire sealing gland nut for direct cable attachments onto a locking 4-pole Euro-style connector for added security of the wire terminations. The gland nut may be removed in provision of alternative conduit or flex tubing landed requirements.
