USB Powered, TEDS Compliant, CCLD Modules (1, 2 and 4 channels)
Signal Conditioning for 200V polarization voltage & pre-polarised microphones (sets)
The GRAS 12AQ is a dual channel power supply/signal condition suited to multiple measurement microphone types. The GRAS 12AK can be used with pre-polarised microphones and those requiring a 200V polarisation voltage and CCLD microphone sets. The GRAS 12AQ is particularly useful where a range of different microphone types have to be used.
The GRAS 12AQ can be controlled manually or via its RS 232 interface.
The GRAS 12AQ is a very practical unit offering a combination of wide dynamic range and low noise floor. The option to run the unit on batteries can be helpful where isolation from mains noise proves difficult. Gain can be set from -20 dB to + 70 dB, switchable in 10 dB steps. The signal output is via a BNC connectors. Linear and A-weighting filters are included and there is a switchable 20 Hz high pass filter.
The GRAS 12AK is equally at home in laboratories, testing and quality control environments.
