AUDIO PRECISION APx1701
The Audio Precision APx1701 stands out in the realm of audio testing equipment with its exceptional signal-to-noise ratio of 134 dB. This device offers a fixed-gain amplification of 20 dB across a broad frequency range from DC to 100 kHz, making it an indispensable tool for professionals.
In the critical frequency range of 10 Hz to 20 kHz, the APx1701 exhibits a remarkably low residual THD+N of ≤ -106 dB (with an 80 kHz bandwidth), and its frequency response is tightly controlled at ±0.08 dB when DC-coupled. The device is designed with two independent channels that boast power ratings of up to 100 W per channel into 8 Ω, ensuring ample power for rigorous testing environments.
Equipped with both balanced and unbalanced microphone inputs, the APx1701 accommodates a wide variety of audio applications, whether you're using measurement microphones or devices under test (DUT). The balanced inputs come with switchable +48 V phantom power, catering to condenser microphones, while the unbalanced inputs support switchable CCP (Constant Current Power) and are TEDS-capable (Transducer Electronic Data Sheet), enhancing versatility.
As audio devices grow increasingly complex—ranging from wireless Bluetooth™ speakers to active noise-canceling headphones—the need for efficient and adaptable testing solutions has never been more critical. The APx1701 seamlessly integrates with APx500 audio measurement software and pairs with any APx500 Series analyzer, creating a comprehensive platform that evaluates the performance of electro-acoustic devices along with their analog and digital components.
