We have a product called the EQM-311. It replaces the belt pack electronics with the in-line wafer board electronics used on the CM-311AE to make a wired wireless but we do not offer the option to go the other way.

To make a CM-311AE hard-wired, you need a 9V battery clip, a 1/4" mono phone plug, a 4.7 microfarad electroytic capacitor, and a Radio Shack 1/4"-jack-to-A3M XLR plug adapter/transformer (part no. 274-017).

Solder the CM-311AE mic cable white lead to the + lead of the 4.7 uF capacitor.

Solder the other end of that capacitor to the phone-plug tip terminal.

Solder the CM-311AE mic cable red lead to the battery clip + (red) lead.

Solder the battery clip - (black) lead to the mic cable shield.

Also solder the mic cable shield to the phone-plug ground terminal.

Plug the phone plug into the Radio Shack adapter/transformer (impedance-matching adapter). Plug the XLR end of that adapter into your mic input with phantom power turned off.

Please send me your email address, and I'll send you a drawing of this wiring.
