The AI7131A and AI7187C chips handle transmission and noise cancellation, delivering 48KHz\/16-bit audio at 25ms latency with a 98dB signal-to-noise ratio. Each transmitter has a 90mAh battery providing up to 7 hours of recording. The 750mAh charging case recharges the transmitters in approximately 1.5 hours. A Karaoke mode allows live audio monitoring during recording.

The 2.4GHz transmission operates independently of Bluetooth, with no pairing process and no app required. AI noise cancellation reduces background noise at the recording source on each transmitter. Karaoke mode passes audio to the device speaker during recording, allowing the subject to hear themselves in real time.

The Lightning plug receiver inserts directly into the iPhone charging port with no driver installation, pairing process or app required. Two transmitters can be active simultaneously.\u003c\/p\u003e\n\u003ch4\u003eAI noise cancellation — AI7131A + AI7187C chips\u003c\/h4\u003e\n\u003cp\u003eThe AI7131A transmitter chip and AI7187C receiver chip handle the noise cancellation processing on each transmitter, isolating the speaker's voice from ambient background noise at the recording source before transmission. The result is cleaner audio at the iPhone without relying solely on post-processing.\u003c\/p\u003e\n\u003ch4\u003e48KHz\/16-bit, 98dB SNR, 25ms latency\u003c\/h4\u003e\n\u003cp\u003eThe system records at 48KHz sample rate and 16-bit depth — the standard specification for broadcast and professional audio. The 98dB signal-to-noise ratio indicates low noise floor. 25ms end-to-end latency keeps audio sync with video practical for direct recording without post-production correction.\u003c\/p\u003e\n\u003ch4\u003e7-hour transmitter battery, 750mAh charging case\u003c\/h4\u003e\n\u003cp\u003eEach transmitter has a 90mAh battery providing up to 7 hours of recording on a single charge.
