| - | Reported by Peter oz1pif and later confirmed by many others the rear din connector has a design error. The audio input pin also has a 5 volt dc voltage and when using an audio transformer you need to include a decoupling capacitor to avoid transformer saturation. | + | Reported by Peter oz1pif and later confirmed by many others the rear din connector has a design error.

| - | One can use a audio transformer but this is not mandatory. When using an audio transformer keep in mind the recommendation above. Include a decoupling capacitor as well ensure the audio shield is starting at the Orion chassis way up to the actuall microphone body. | + | One can use a audio transformer but this is not mandatory.

| When connecting the rear connector directly to the microphone amplifier please ensure the amplifier can run in unbalanced mode. Some equipment recognizes balanced / unbalanced connection automatically and some require additional configuration. Furthermore just like all other configurations ensure the audio shield is starting at the orion chassis all the way up to the actual microphone body. | When connecting the rear connector directly to the microphone amplifier please ensure the amplifier can run in unbalanced mode.
