The DataLocker AlphaTalk Push-to-Talk 3.5mm Audio Connector (part number AT2000-PTT-HS-G) is a headset component designed for devices with a standard 3.5mm audio jack, providing push-to-talk functionality for secure audio communication in high-security environments. It operates via plug-and-play without requiring drivers or software, utilizing a four-pole 3.5mm connector that carries both microphone and speaker signals. The push-to-talk mechanism requires continuous button depression for transmission, with communication ceasing upon release.
Technical specifications include an input impedance of 32 Ω ± 15%, headphone sensitivity of 95 dB S.P.L/MW (1 kHz) ± 3 dB, and microphone sensitivity of –44 dB ± 3 dB (0 dB = 1 V/Pa at 1 kHz). The frequency response ranges from 20 Hz–20 kHz for the headset and 100 Hz–10 kHz for the microphone. The device incorporates passive noise cancellation, acoustic shock protection, and a 7.8 ft (2.4 m) cable. It complies with TAA, RoHS, FCC, and CE standards and is backed by a three-year limited warranty. Technical documentation is available in a DataSheet and User Manual.
