Audio quality and signal integrity

The Sennheiser Profile Wireless 1-Channel Set delivers reliable 2.4 GHz RF transmission across a line-of-sight range of up to 245m, maintaining audio integrity even in crowded environments. It captures a 60–20,000 Hz frequency response and uses 32-bit float internal recording to preserve detail across an extreme dynamic range. Safety Channel Mode and Backup Recording Mode protect against real-time clipping and wireless dropouts.

Internal memory and recording

With 16 GB of onboard storage in the clip-on transmitter, users can record up to 30 hours of audio directly to the device - ideal for backup logging or working in RF-congested areas. Recording can be started and stopped from either the transmitter or the receiver, and the mic continues recording internally even when the RF signal is interrupted. The omnidirectional condenser capsule handles up to 113 dB SPL, offering clean capture in various conditions.

Connectivity and device support

Designed for hybrid shooting setups, the receiver includes USB-C and Lightning digital outputs for connections to smartphones and computers, alongside a 3.5 mm TRS analogue output for cameras and field recorders. The mic also features a lockable TRS input, supporting optional Sennheiser lavaliers for more discreet setups. A gyro-driven OLED display ensures readable orientation in any rig, while headphone monitoring allows real-time signal checks without additional gear.

Power and expandability

The transmitter and receiver each run for up to 7 hours on a full charge and recharge in under 2 hours via USB-C. The transmitter can also record for up to 14 hours without transmitting. Mounting options include a cold shoe adaptor, threaded sockets, a magnetic clothing clip, and a compact carry pouch for transportation. The system is also fully expandable when paired with a second transmitter (sold separately) to create a full-featured 2-channel setup.

FAQs

What is the maximum transmission range of the Sennheiser Profile Wireless 1-Channel Set?

In optimal line-of-sight conditions, the system transmits up to 245 m. In typical use cases where the body or obstacles may block the signal, the range reduces to around 150 m. This feature makes it suitable for most indoor and outdoor filming scenarios where mobility is essential.

How long does the internal battery last, and how is it charged?

The transmitter and receiver each offer up to 7 hours of runtime when transmitting and recording. The transmitter alone can record internally for up to 14 hours without transmitting. Charging is achieved via USB-C, and both units fully charge in under 2 hours, making it easy to top up power between shoots.

Can I use the system in different temperature and humidity conditions?

Yes, the system is designed to operate between -10 °C and +45 °C and within a humidity range of 25–95% (non-condensing). Charging should take place between 0 °C and +45 °C. This makes it robust enough for use in a wide range of environmental conditions.

Does the system require an app or manual pairing to set up?

No app is required to operate the Sennheiser Profile Wireless 1-Channel Set. The included transmitter and receiver come pre-paired and automatically connect once powered on. This allows for immediate use straight out of the box, with no configuration needed.

What type of audio monitoring is available on the receiver?

The receiver includes a dedicated headphone output with 25 mW output power and supports headphones with a minimum 32 Ω impedance. This allows for direct audio monitoring during recording or while setting up levels. Real-time monitoring is useful for ensuring signal clarity and avoiding clipping issues.
