GRAS 12BB 4-Channel CCP Power Module with TEDS Support

Technology

The GRAS 12BB  is a four-channel USB-powered CCP power module with TEDS support.

It provides power to four microphone sets without signal degradation, gain modification, or attenuation.

It is intended 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, it can also be used with other brands.  In this case, a utility program provides access to TEDS data on a PC. It can be downloaded here.

Power for the 12BB is provided through a USB cable using a USB 2.0 or USB 3.0 port and a USB-C port on the power module.

A single-channel version is available, the 12BA.
