TYPE 1706
High-temperature CCLD Preamplifier
Microphone preamplifier designed to make acoustical measurements at high temperature - up to 125°C (257°F) - with a constant-current line drive (CCLD) input module.
Request PriceHigh-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 1/2″ 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.
