Despite its origin in the vibration transducer world, the Constant Current Line Drive (CCLD) principle is increasing in popularity in the area of sound and measurement applications. Different manufacturers market transducers using the CCLD principle under different names.
Microphone Preamplifiers by HBK are robust and acoustically optimized for a wide range of environmental operating conditions. The high‐output current capability of our preamplifiers is able to drive extremely long cables without signal degradation - even when measuring high sound pressure levels present at high frequencies. The HBK CCLD and classical preamplifier designs fit our range of 1/2" and 1/4" microphone cartridges.
