Gain and filter switch settings

There are two flush-mounted switches for selecting various combinations of gain and filtering, i.e.:

Gain switch settings:

  • 0 dB - for normal microphone signals.
  • +20 dB - for boosting weak microphone signals.

Filter switch settings:

  • A-Weighting - as required in standard measurements.Linear - to let the microphone signal passunfiltered.
  • High-pass - to cut off unwanted low frequencies.

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 G.R.A.S. 26CF can be used with all G.R.A.S. prepolarized microphones, namely:

  • 1/2-inch 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 maximumstrength and durability.

CCP stands for “Constant Current Power” and describesG.R.A.S. power supplies that maintain a constant level ofcurrent for driving IEPE transducers like this preamplifier which can be used with prepolarized microphone cartridges such as G.R.A.S. 40AD, 40AE, 40AO and 40AQ.
