Can Sony wireless mic be used in wired?

Hi - I have a Sony ECM 77BC wireless lav, but do not have the transmitter unit. Does anyone know if it possible to use this as a wired mic?

I want to run it into my Zoom H4 (so 48V phantom power available). it has a 4 pin connector on it which I would like to be able to ultimate terminate with XLR (to go into the Zoom).

Any ideas?

Tks
 
That shouldn't be a problem. I go the opposite direction all the time with my XLR ECM-77 and a handheld into a Lectrosonics transmitter via a short adapter cable.

Since you don't have a wireless system with which to use this lav, you might be better off sending it back to Sony or to an authorized service center to have it re-configured for use with XLR and phantom power.

Simply converting to an XLR connection is risky, as the mic is not configured at this point for a full +48v. It needs a power supply (inline barrel) to function hard-wired.

I was wondering if there was a risk about using 48V, any idea what voltage the wireless unit uses? (I am presuming it needs some power?)

Also, Could I use another wirelss sustem? I havean audio techica wirelss system - wasn;t sure about compatability though

Not sure what the specs are for power supply to the mic element, but HERE'S the same mic for hard-wired use.

It could be used with AT wireless systems, but again it would need to be rewired for a different connector. AT wireless mics use either 5-pin miniXLR (as opposed to the 4-pin that you have), or 1.8".

Typically the capsule of a lav requires about 5 volts. Your Sony mic could be easily reconfigured to be compatible with an AT system's input - they both use the same 4 pin connector but I've read that they are wired differently. You can also get power supply barrels that will take the 48volt phantom from a conventional XLR connection and drop it down to the required 5 volts. Ambient's Eumel is a gadget that does that, available for a variety of mic connectors and wiring schemes.
