Changing K2 Microphones for the K3

[John Huffman-3]

For my K2 I use the MH2, MD2, and a Heil Proset.  For flexibility,
instead of putting the 5.6k resistor in the K2, I put one each in the
microphone connector shells of the MH2 and MD2.

I have ordered my K3 and expect it in 2008, so I want to be ready.

Will I need to remove the resistors from the mic connector shells of the
MH2 and MD2 in order to use them with the K3?

I don't think so, John. My mics are wired up as per the K2 "standard". Only one is an electret, and has a resistor in the shell. It works OK with the K3.

Does the unmodified MD2 work FB in the K3?

Thanks,

   Paul, yes it does. That is what I'm using on my K3. Just make sure to
turn on front panel bias. (So very easy to do, and even easier to
forget to do!)

John,

Since you have the resistor in the connector, it will work fine with the
K3 - BUT - the mic bias will be coming from the resistor in the mic
itself - for that reason, do not turn the K3 microphone bias on.
Others using those same microphones with the K3 would want to turn bias
on because they have no resistor in the connector body.
