Powering & Connection – CCP
General Information
The powering and connection is electrically exactly the same as for G.R.A.S. CCP standard
microphone sets. A constant current input module that can deliver 4 mA and 24 V unloaded CCP
voltage supply is required. If the constant current supply is lower, the capability of driving long
cables is reduced and consequently the upper frequency is reduced. If the voltage supply is lower
it will reduce the dynamic range.
Connection
The flush-mount microphone sets are provided with an integrated cable that is only 1.1 mm in
diameter. The cable is terminated with a Microdot male connector. A G.R.A.S. AE0046 Microdot
- BNC Adapter is included. The cable length is:
•
1.5 m (4.92 feet), in standard flush-mount microphone sets
•
Customized length, when ordered as -CL variant
