The problem still remains. This mic is connected in the three wires configuration. Look at the jack, there are three pins (they are divided by black rings). Pin 1 is ground, pin 2 is audio, pin 3 is power for mic.
Tascam is providing only two wires connection. Ground is on pin 1, audio and power together are on pin 2. When you want to use this mic with Tascam, you should reterminate it to two wire configuration. You can terminate one mic to one mono jack. And you can terminate two mics to one stereo jack too. It is very easy, somebody with basic soldering skills can do it in five minutes. Here is basic schema.
