    1.  CCP = constant current power, these microphone sets require a constant current power supply to operate correctly


    2.  ½" CCP sets come with a BNC connector, ¼" and ⅛" CCP sets have a microdot connector (apart from Type 46BD-S1 which is SMB)


    3.  all ½" LEMO microphone sets come with an integral 7-pin 1B LEMO connector, a cable is not included


    4.  all ¼" and ⅛" LEMO microphone sets have a 5-pin LEMO connector on preamplifier (cables for 7-pin 1B LEMO available separately)


    5.  G.R.A.S. microphone sets (CCP and LEMO) do not include a cable, cables are available separately


    6.  Many G.R.A.S. microphone sets (CCP and LEMO) include (pressure) capsules that have front vented option and high temp. preamps
