    “Studio grade” condenser mics usually require 48 volt biasing. You would need to have a way to supply the necessary voltage externally to the mic. Then the output of that can go to the balanced in on the 6700.

    The Lewitt web site indicates that that mic uses a 7-pin connector which connects to the power supply that they provide. I did not see technical specs for the power supply but it must provide power to the mic. It is a bit different than most condenser mics used professionally as those use a 3-pin XLR connector with 48 Volt Phantom power supplied on pins 2 and 3.

    Is there a 3-pin male XLR on th epower supply enclosure that would be the mic out?

    If there is more info on their web site regarding the actual configuration I did not see it.

    Edit: There is a manual download link and yes there are standard 3-pin XLR connectorrs on the PSU enclosure for the mic output. You should be able to use one of those to connect the radio.

    I don't own any Lewitt mics but I'm sure you can make an adapter.

    In case no one has mentioned it, a condenser mic will pick up every little sound in your house and maybe your neighbors home as well. That includes fans, your central AC, the tv in the living room. They sound great in a studio in a controlled environment but you will have a lot of background noise in your transmissions. I would never use one in this situation. I own several and had to turn off the central AC when recording with them. A good dynamic mic is a better choice for a radio and doesnt require phantom power. You can try and see if you like it but be sure to monitor/record your audio to decide if it is what you want. I use a Heil PR30 on every radio I have owned for the last 8 years and get great audio reports.
