The DataLocker AlphaTalk Push-To-Talk (3.5 mm) (Part Number AT2000-PTT-HS-G) is a Trade Agreements Act (TAA) compliant, driverless plug-and-play audio device designed for controlled voice transmission in high-security environments. It utilizes a four-pole 3.5 mm connector combining microphone and speaker functions, operated via a built-in push-to-talk button that must be held to transmit audio. The unit incorporates DoW-standard passive noise-cancellation for the microphone and acoustic shock protection to guard against volume spikes.
Technical specifications include a 7.8 ft (2.4 m) cable, an input impedance of 32 Ω (± 15%), headphone sensitivity of 95 dB SPL/mW (± 3 dB), and microphone sensitivity of –44 dB (± 3 dB). The device operates with a frequency response spanning 20 Hz to 20 kHz for the headset and 100 Hz to 10 kHz for the microphone, and is supported by a three-year limited warranty.
