New Stand-Alone Sound Recorder

Brüel & Kjær (UK)’s new stand-alone recorder, based on the PULSE LAN-XI analyser hardware, makes high-quality data recording supremely easy, even in situations where no PC could survive.

LAN-XI Notar™ allows PC-less recordings directly to a small and rugged solid state memory card - applications where the use of a PC is not an option – such as in-flight or in-vehicle measurements or other harsh environments.

On other recorders, changing the input range on each channel takes time, is usually awkward on a recorder’s limited user interface and opens up the possibility for overloads or under-range errors. Such complications are things of the past thanks to LAN-XI Notar’s huge 160dB Dyn-X single input range.

Recordings are saved directly to a removable memory card in WAV format, including the necessary calibration information - making it a flexible format for Brüel & Kjær’s customers already using the company’s PULSE Time analysis software, as well as third-party analysis packages, such as Matlab.

Together with Brüel & Kjær’s new LAN-XI Battery Type 2831, this small, rugged solid-state recorder can operate for more than seven hours on a single battery. It is also possible to swap the battery in the field for even longer measurement time.

Using a PC, or other device with an internet browser, the user can setup the recorder and enter the transducer sensitivities. Once this is done, the PC can be removed and the system will function as a stand-alone recorder with single button control.
