Nor1204 ¼ inch preamplifier

Details:
For applications requiring quarter-inch microphones this preamplifier will optimise the measurement configuration. The outside diameter of the preamplifier matches that of the Nor1244 and Nor1245 microphones in order that the assembly introduces the minimum disturbance to the field being investigated. Its electrical performance is closely equal to Nor1201.

The body of the preamplifier is made of stainless steel and fitted with an integral 2-metre lightweight cable. This is terminated with a standard LEMO seven pin connector compatible with the standard range of Norsonic extension cables.
