Type 26CA


Type 26CA
A ½" preamplifier for connection to G.R.A.S. CCP1 input channels , e.g. see Type 12AL. The Type 26CA has a standard BNC output connector and is for use with prepolarised microphones. It is delivered without a cable. The built-in TEDS2 chip enables it to be programmed as a complete unit together with a microphone.
The Type 26CA can be used with the following ½" G.R.A.S. prepolarised microphones:
  • Type 40AE
  • Type 40AD
  • Type 40AO
  • Type 40AQ
And with the following ¼" G.R.A.S. prepolarised microphones using the Adapter RA0019:
  • Type 40BE
  • Type 40BD
