GRAS 12BC, 12BF and 12BD LEMO Power Modules with TEDS Support

Connection: LEMO
Traditional 200 V
Channel(s): 1, 2 or 4
TEDS via USB

Technology

The GRAS 12BC, 12BF and 12BD  are, respectively, single- two- and four-channel USB-powered LEMO power modules with TEDS support.

These power modules provide power to microphone sets without signal degradation, gain modification, or attenuation.

This series excells as a simple and cost-effective interface between TEDS-enabled measurement microphones and any Audio Precision APx series analyzer, which will automatically extract TEDS data for seamless integration.

However, these power modules can also be used with other brands. In this case, a utility program provides access to TEDS data on a PC. This utility program can be downloaded here.

Power for 12BC, 12BF and 12BD is provided through a USB cable if the port can supply a minimum of 1.5 A that is required by the module. Power can be supplied via a USB 2.0 or USB 3.0 port connected to a USB-C port on the power module or AC mains power through the AUXPWR port if the minimum 1.5 A is not available through the USB-C port.

If more channels are needed, multiple power modules can be used concurrently.
