Typical applications and use

CCP inputs (ICP ®)

Prepolarized microphones

1/2″ precision microphones

High levels and high frequencies


The G.R.A.S. 26CA 1/2” CCP Standard Preamplifier is a small, robust unit and uses a CCP power supply (ICP ®), e.g. G.R.A.S. 12AL. 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.

The 26CA is delivered with Generation II TEDS. The calibration data is programmed into the built-in TEDS according to IEEE 1451.4 using UDID I27-0-0-0U. If your measurement platform supports Transducer Electronic Data Sheets you will be able to read and write data like properties and calibration data.

Generation II TEDS chip (DS2431) may require updated system software.

It can be used with all G.R.A.S. prepolarized microphones, namely: 1/2″ microphones: G.R.A.S. 40AE, 40AD and 40AQ 1/4-inch microphones: G.R.A.S. 40BE and 40BD, using the optional 1/2″-inch to 1/4-inch adaptor RA0019.

It has an integrated BNC output connector. The casing is made of stainless steel for maximum strength and durability.
