Sennheiser has announced a single-channel version of the Profile Wireless 2.4GHz all-in-one microphone solution launched in late 2024. The streamlined single-mic system comes in a compact bag and includes a second USB charging cable instead of the charging bar of the earlier two-channel version.
Designed to be lightweight and ultra-portable, the new version covers typical usage scenarios of solo creators, while accommodating later expansion of the system by including the same two-channel receiver as the Profile Wireless two-channel system. Also, a 32-bit float firmware update for all Profile Wireless systems is available for download on the Sennheiser website.
‘We’re now catering for the solo creator, who does not require the full two-channel package but would rather like to save on weight and cost and still have Sennheiser audio quality,’ says Sennheiser Product Manager for Broadcast & Film, Hendrik Millauer. ‘Profile Wireless one-channel is also ideal for the casual user looking for a wireless mic to hook up to their laptop, for example.’
Like the two-channel version, the solo system is quick and easy to set up – no app is required. It can be used on cameras, with smartphones and computers, and can be combined with an external lavalier microphone or used to create a wireless boom. The mic has an operating time of up to seven hours, and 16GB of memory for up to 30 hours of internal recording.
The system comes in a rugged pouch that includes the clip-on microphone with mini windshield and magnetic mount, a two-channel receiver, two USB cables, USB-C and Lightning adapters, a camera cable and a shoe mount adapter. As all Profile Wirelesss components can be bought separately, nothing stands in the way of expanding the system to two channels at a later point in time.
‘With the latest Profile Wireless firmware update, we’re addressing user requests for a 32-bit float functionality,’ Millauer says. ‘This will allow creators to record with extremely high dynamic range, and help them to recover clipped audio.’
For 32-bit float recording, Profile Wireless combines the audio signals of the two A/D converters inside the Profile Wireless mics to create a single 32-bit float audio stream.
Creators who prefer 24-bit recording due to its lower memory requirement still have the option to deactivate 32-bit float recording and turn on the Safety Channel Mode. This will output a ‑6dB version of the audio in addition to the original sound level and thus help protect against clipping.
To update their Profile Wireless system to firmware version V4.1.0, creators are asked to visit www.sennheiser.com/profilewireless. Under Downloads, they will find various firmware updates for Mac and PC, with a smart tool guiding them through the update process for the receiver and transmitter(s). Please note that the first batches of the Profile Wireless 1-channel mic also need to be updated to firmware version V4.1.0.
Millauer concludes, ‘With the addition of the one-channel system and 32-bit float recording, Profile Wireless becomes the most versatile tool for creators who value excellent sound and see it as a key differentiator for quality content.’
The Profile Wireless 1-channel retails at €199 (MSRP), US$199 (MAP) or £169 (MSRP).
