AT-2 Professioal Audio Analyzer

The AT-2 Audio Analyzer is a high-performance USB audio measurement interface engineered for professional acoustic analysis, loudspeaker optimization, audio system calibration, and electroacoustic testing. Designed to meet the demanding requirements of audio engineers, system integrators, acoustic consultants, cinema technicians, and research professionals, the AT-2 combines precision measurement capabilities, robust hardware architecture, and seamless software compatibility into a compact and versatile platform.

​

As modern audio systems continue to evolve in complexity and performance, accurate measurement tools have become essential for ensuring optimal sound quality and system reliability. The AT-2 addresses these challenges by providing a complete measurement solution capable of handling both acoustic and electrical testing applications. Whether deployed in live sound venues, cinemas, recording studios, commercial installations, educational institutions, or research laboratories, the AT-2 delivers the accuracy and flexibility required for professional audio analysis.

​

At the core of the AT-2 is a high-resolution audio engine supporting up to 24-bit / 192kHz operation. This enables precise capture and reproduction of audio signals across the entire audible spectrum while preserving fine measurement details. The device offers exceptional performance with a dynamic range of 106 dB and ultra-low Total Harmonic Distortion plus Noise (THD+N) of less than 0.0012%, ensuring reliable and repeatable measurement results in critical applications.

​

The AT-2 features two balanced XLR input channels designed to accommodate a variety of audio sources, including measurement microphones, condenser microphones, dynamic microphones, audio processors, mixing consoles, and other professional audio equipment. Each input is equipped with independently switchable 48V phantom power, providing the flexibility needed for professional measurement microphones and condenser-based testing systems. Dedicated SPL range selection controls allow users to switch between high and low sound pressure level measurement modes, enabling accurate analysis across a wide range of acoustic environments.

​

In addition to acoustic measurements, the AT-2 supports electrical measurement applications through dedicated voltage measurement ranges. Users can easily switch between high-voltage and low-voltage measurement modes, making the device suitable for amplifier testing, signal verification, and system diagnostics. The integrated analog loopback functionality further enhances measurement accuracy by providing a stable reference signal path for transfer function analysis and frequency response measurements.

​

The output section of the AT-2 is designed to provide maximum flexibility for professional workflows. Two balanced XLR outputs deliver clean, low-noise signals for loudspeaker testing, processor alignment, and system calibration. Additional RCA outputs provide convenient connectivity for consumer and semi-professional audio equipment. A precision output attenuation control allows users to adjust signal levels with exceptional accuracy, ensuring proper gain staging and measurement consistency.

​

One of the most distinctive features of the AT-2 is its built-in 1.9-inch TFT color display. Unlike conventional measurement interfaces that rely entirely on computer software for monitoring, the AT-2 provides real-time visual feedback directly on the hardware unit. Users can instantly view input signal levels, output signal levels, voltage readings, and attenuation settings, significantly improving operational efficiency during setup and testing. This standalone monitoring capability is particularly valuable in field environments where quick system verification is essential.

​

The AT-2 has been developed with broad software compatibility in mind. It integrates seamlessly with many of the industry's most widely used audio measurement platforms, including SMAART, SysTune, SATlive, ARTA, REW (Room EQ Wizard), AudioTools, and VOS4. This extensive compatibility ensures that users can incorporate the AT-2 into existing workflows without the need for specialized software or complicated configuration procedures.

​

Deep integration with VOS4 measurement software provides an enhanced user experience for acoustic tuning and system optimization tasks. Combined with the AT-2's low-latency performance, users can conduct real-time measurements, transfer function analysis, impulse response testing, and frequency response evaluation with confidence and precision.

​

Platform compatibility is another key advantage of the AT-2. The device supports low-latency ASIO drivers for Windows systems, enabling professional-grade performance for demanding measurement applications. On macOS platforms, the AT-2 operates without requiring additional driver installation, simplifying deployment and reducing setup time. This cross-platform flexibility makes the analyzer suitable for a wide variety of professional environments.

​

Beyond acoustic measurements, the AT-2 also supports advanced impedance analysis when used with the dedicated impedance adapter. This capability allows users to measure loudspeaker impedance curves, capacitance, inductance, and resistance characteristics. Such functionality is particularly valuable for loudspeaker manufacturers, research institutions, and advanced system designers seeking deeper insight into transducer performance and electrical behavior.

​

The physical construction of the AT-2 reflects its professional focus. Housed in a durable full-metal chassis, the device is built to withstand the rigors of field deployment, touring applications, and installation environments. Despite its rugged construction, the analyzer maintains a compact footprint that allows for easy transportation and integration into portable measurement systems.

The AT-2 is ideally suited for numerous professional applications, including loudspeaker frequency response measurements, room acoustics analysis, SPL monitoring, cinema system calibration, live sound optimization, audio system commissioning, amplifier testing, educational training, and product development. Its comprehensive feature set enables users to perform accurate measurements quickly and efficiently while maintaining the highest standards of precision.

​

By combining high-resolution audio performance, professional connectivity, real-time monitoring, advanced measurement capabilities, and broad software compatibility, the AT-2 Audio Analyzer establishes itself as a powerful and versatile solution for modern audio professionals. Whether optimizing a large-scale sound reinforcement system, calibrating a cinema environment, conducting acoustic research, or performing routine system verification, the AT-2 delivers the reliability, accuracy, and flexibility required to achieve exceptional results.
