GRAS 12BA
1-Channel CCP Power Module with TEDS Support

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

It provides power to one microphone set without signal degradation, gain modification, or attenuation.

GRAS 12BA 1-Channel CCP Power Module with TEDS Support

 

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. This program can be downloaded here.

Power for the 12BA 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.

If more than one microphone must be used, a four-channel version is available, the 12BB.

Alternatively, multiple power modules can be used concurrently.
