SONY ECM s 220 microphone
New to this Forum and my first question is does anybody know, how to get the right voltage to the Sony ECM -s220 Microphone.
It was part of a Sony Dat recorder (Sony DT3) i think around 1991. I do not have the recorder anymore, but i wondered if i can use the mic in connection with some other equipment, or just dump it. I do field recording for fun and i have quite a good selection of Microphones, i thought why waste it, the inside looks interesting. thank you |

The ECM-S220 has a separate power cable. I don't remember the voltage, but
you could start with 1.5V and work up. I don't believe the polarity matters, but I'm not sure. |

If you are wrong, Bubenheim doesn't have a mic anymore. In that case, I have an ECM-S220 I could sell him. grin Polarity often doesn't matter in such microphones. The amplifier is often a MOSFET, which doesn't "care" which way the battery is connected, as it's internally symmetrical. |

Fortunately, my service manual for the recorder was easy to find.
The jack has +5V on the tip. This is supplied through a single-transistor regulator through a 100-ohm resistor. There are also bypass caps to keep noise off the line. |

Try a 9V battery in series with a 2.2K resistor to each signal pin, then 10 uF DC blocking caps between each of the signal pins and the output. It is possible to drive those with phantom power with only a little extra electronics; three caps and four resistors per channel. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The ECM-S220 uses a separate power cable. It's possible the main cable works with PNP, but I don't know. |
