Endevco model EM26CBMeggitt Sensing Systems, a Meggitt group division, has announced the Endevco model EM26CB, a ¼” ISOTRON microphone preamplifier with Microdot coaxial connector, designed for use with prepolarized condenser microphones in support of a variety of general purpose acoustic measurement requirements.

With a frequency response ranging from 2 Hz to 200 kHz (±0.2 dB) and featuring A-weighted noise levels of ? 2.5 µV rms, the Endevco model EM26CB is constructed of corrosion resistant stainless steel and incorporates a small ceramic thick-film substrate with very high input impedance. The preamplifier is also shielded by a guard ring to minimize the influence of stray capacitance and microphone signal output interference.

Recommended accessories for the Endevco model EM26CB include 1/4” condenser microphone models EM40BE and EM40BD; the model EM42AA handheld pistonphone calibrator, which facilitates field checks of complete acoustic measurement systems, as well as in-house microphone calibrations; the model 4416B ISOTRON power supply (2-20 mA); and the model 133 three-channel signal conditioner. All Endevco acoustic sensors and instrumentation are also backed by a five-year comprehensive product warranty, with quantities of the model EM26CB available for immediate customer shipment.
