CCP High Temperature Preamplifier with BNC Connector GRAS 26CA-HT 1/2”

Typical applications and use

• Prepolarized microphones
• Operating temperature up to 120 °C (248 °F)
• Low noise floor and wide frequency range

Design

• The GRAS 1/2″ Preamplifier 26CA-HT is similar to the GRAS 26CA Standard Preamplifier, but optimzed for use in high-temperature applications up to 120 °C (248 °F).
• It uses a CCP (Constant Current Power) supply, e.g. GRAS 12AL 1-Channel CCP Power Module with A-weighting filter. It has a very low inherent noise level, a large dynamic range and a frequency response from below 2 Hz to above 200 kHz. Its small ceramic thick-film substrate has a very high input impedance, and is shielded by a guard ring to minimise the influence of stray capacitance and microphonic interference.
• It has TEDS* according to IEEE P1451.4 for easy self identification and reading of calibration data.
• It has an integrated BNC output connector and can be used with all GRAS prepolarized microphones. The casing is made of stainless steel for maximum strength and durability.
