High-temperature CCLD Microphone Preamplifier Type 1706 enables you to make acoustical measurements at temperatures up to 125°C (257°F) with a constant-current line drive (CCLD) input module. You can connect ½″ prepolarized microphones to the preamplifier. The preamplifier’s low output impedance allows problem-free use of long extension cables. The robust, compact design means that you can use Type 1706 over a wide range of environmental conditions.
