Why you'll like it

• 2-transmitter system — record two audio sources simultaneously to one receiver
• 50m barrier-free range — 2.4GHz wireless transmission
• 20ms latency — low-delay audio for video recording synchronisation
• 8hr transmitter use — 70mAh battery per transmitter, ~80min charge time
• 600mAh charging case — recharges transmitters on the go

Designed for recording and content creation

The KR17 uses two transmitters (worn by speakers or clipped to clothing) that send audio to a single receiver connected to a camera, phone or recorder via the included P4 cable. The 2.4GHz frequency provides a 50m barrier-free transmission range. Each transmitter uses a digital silicon mic head with a ceramic antenna; AI noise reduction processing filters environmental background noise. The sampling rate is 32KHz with a 20Hz–20KHz frequency response range and 20ms latency — low enough for video recording without audible delay. Each transmitter's 70mAh battery provides approximately 8 hours of use per charge, with an ~80-minute charge time. The 600mAh charging case recharges both transmitters away from a mains socket. No certifications listed in source documentation. Curated by Aetheo for recording and content creation.

Key features

2-transmitter system — 2.4GHz, 50m

The KR17 includes two transmitters and one receiver — two audio sources can be captured simultaneously and combined into the receiver's output. The 2.4GHz wireless transmission provides a 50m barrier-free range. In environments with obstacles (walls, dense crowds), actual range will be reduced. The ceramic antenna design in each transmitter supports stable signal in the 2.4GHz band. The 2.4GHz band may experience interference from other 2.4GHz devices such as WiFi routers and Bluetooth in dense RF environments.

20ms latency — 32KHz sampling, 20Hz–20KHz response

The 20ms transmission latency allows audio and video recording without perceptible delay when combined in post-production or played back directly. The 32KHz sampling rate captures audio for voice recording and speech. The 20Hz–20KHz frequency response covers the full audible range. AI noise reduction in the transmitters reduces constant environmental background noise during capture.

Transmitter battery — 70mAh, ~8hr use, ~80min charge

Each transmitter has a 70mAh battery providing approximately 8 hours of use per charge. Charge time is approximately 80 minutes per transmitter. The transmitters charge via the 600mAh charging case — the case acts as a portable power bank for the transmitters. Full case capacity provides multiple recharge cycles for the transmitters when away from a mains socket.

600mAh charging case — P4 cable output

The 600mAh charging case stores and charges both transmitters when not in use. The case functions as a combined carry case and portable charger for the transmitters. The receiver connects to cameras, phones or recorders via the included P4 cable. A storage bag is included for carrying the full kit. The P4 cable connector type should be verified against the target recording device's input before purchase.
