Rode Lavalier - 3KΩ Output Impedance - Does it Matter ?

[Douglas87]

I understand that is usually no need to worry about microphone output impedances because most are 50-300Ω and several times smaller than theload they feed.However, the Rode Lavalier's data sheet gives its output impedance as 3KΩ.Even the Mix-Pre D's mic input is only 2kΩ.Does this mean that the Rode Lavalier needs to be used with a recorder with a high input impedance [e.g. Edirol R-09HR at 30kΩ or Sony PCM-D50 at 22kΩ ?]

I agree that seems unusually high. Sometimes I question whether advertising prose has been "corrected" (or mangled) by non-technical advertising gerbs. I have used mine with several different pieces of equipment with no noticeable impedance loading issues.
