4 Installation and Connection

4.1Introduction All Discreet Acoustics Compact microphones are con-

denser microphones and therefore require a power supply (phantom power). The microphones have been designed for connection to microphone inputs with 9 to 52 V phantom power. To connect Discreet Acoustics Compact microphones to inputs without phantom power, refer to Section 4.4.

4.2CGN 99 … Gooseneck

Microphones Refer to figs. 9 and 12.

Note:

Refer to figs. 10 and 11.

1.Use the optional PS 3 F-Lock panel mount socket to install the microphone in a tabletop or an optional SA 60 stand adapter to mount the microphone on a floor or table stand.

For even better vibrational noise rejection, you can fix the microphone to the tabletop with an optional H 500 or H 600 shock mount.

2.Use a shielded cable to connect the microphone to a microphone input with phantom power.
