The AtlasIED AA100PHD is expertly designed for business environments requiring efficient audio distribution for paging and background music. It is perfect for setups that demand a single unit to manage multiple audio sources, such as microphones and line-level inputs, across diverse speaker systems. Its compatibility with 25V, 70.7V, and 4Ω outputs supports both extensive distributed and low-impedance speaker setups. Additionally, the configurable paging feature prioritizes announcements, making it ideal for environments where communication is key.

Why Choose This Model

Opt for the AA100PHD for its robust combination of a 100W RMS output, versatile input options, and advanced diagnostic features. The first two inputs can be toggled between microphone and line functions, with phantom power available for mic inputs, ensuring flexibility in various applications. The amplifier’s built-in paging mute feature, which silences other inputs in favor of Input 1, allows for seamless prioritization of important messages without extra equipment.

Installation and Integration

Installation is made simple with support for a wide range of speaker systems. The four-position Phoenix connector facilitates secure and reliable speaker connections. The rear-panel DIP switch enables a customizable Zone 2 output mix from any of the four inputs. Operators can control inputs and volume remotely from up to 200 feet, thanks to the remote input selection and level control capabilities. With dimensions of 8.27″ W x 3.66″ H x 10.87″ D and weighing 13 pounds, this amplifier fits comfortably into most standard installations and operates on 110V-120V power.

Performance Highlights

Delivering a solid 100W RMS output into a 4Ω load from 50Hz to 15kHz at 0.5% THD, the AA100PHD ensures clear and consistent audio output. Its frequency response covers the essential range for both voice and music, making it suitable for varied audio needs. The ability to switch between 25V, 70.7V, and 4Ω operations allows for dynamic system configurations. The 50Hz refresh rate further complements its audio performance.

What Makes It Different

The integrated Push Here Diagnostic (PHD) sets this model apart, offering a unique self-test for speaker-line integrity. Activating the PHD test checks for wiring and impedance issues, verifies speaker tap settings, and ensures speaker wire integrity—all crucial for optimal audio system performance. These built-in diagnostics, along with remote operational capabilities and customizable paging settings, make the AA100PHD a versatile choice for complex audio environments.
