Sound-wise would this be as good as a 77B? That is, if I don't need the smaller profile of the 77B would this 44B sound as good?
Asked by: Thomas
The main difference between the ECM 77B and 44B other than physical size, would be the frequency response. The 77B extends lower than the 44B, however generally for speech and broadcast applications those would be rolled off. If size is of no importance, the ECM 44B is a fine choice and very popular in broadcast applications.

Will this mic work with Scarlett Focusrite 2i2?

Will this mic work with Scarlett Focusrite 2i2?
Asked by: Gary
Should be able to work. Make sure AA battery is installed in the XLR barrel. Remove battery when not in use do prevent the Lav from damages from acid leaks. It's a great lav to have and audio is great. Have 2 for talking heads.

To link this to a DSLR with a 3.5mm jack in a way that adds to the length of the cord, I could use a 20' Kopul Premium Performance 3000 Series XLR M to XLR F Microphone Cable, plus a Kopul LMT100 - Low to High Impedance Matching Transformer, correct? The length will not degrade the sound, and I can go right into the camera?
Asked by: Brian
Correct. A standard XLR mic cable in addition to the Kopul LMT-100 cable will allow you to connect the ECM-44B directly to a DSLR. At this length would not affect the audio quality.

I am having trouble opening up the mic to replace the battery. What am I doing wrong?
Asked by: Anonymous
The barrel of the Sony ECM-44B is threaded in the center and should unscrew with little resistance.
