Maybe John can clarify this.

Yes, this is correct, on the G3 you have to ground the tip for the line input.

It is this grounding of the unused input that switches the inputs on and off.

But - only on the G3 is it a *must* - you don't do it on the G2 and G1.

Would shorting the tip to ground on the G1 and G2 be harmful - in as much as you are shorting out the mic power supply ?

I'm not certain - I know it's essential for the G3.

Ring Sam Davison (Service Supervisor) or Andy Lillywhite (Chief Engineer) at Sennheiser UK and ask. They will know.

I've ran SK100 G2's line level without the tip grounded.. no problems that I'm aware of.
Don't know about the G1 or even if it has a line level option.

The G1 does have the line level input , using ring/sleeve as on the later models .

The line input cables I made up work just fine with the tip left unconnected .

This is what we have been saying all along - G1 and G2 work fine without the tip being grounded for line level. The question was *can* it be grounded.

For the G3 it *must* be grounded - the question was regarding a line cable wired for G3 being used with a G1 or G2.

And I don't know the answer to this - you have to ask Sennheiser.

The G1 is exactly the same as the G2 regarding wiring.

I was stating my experience in response to Derek's post, "Would shorting the tip to ground on the G1 and G2 be harmful"

Exactly - which is why my response was "ask Sennheiser".

You did not actually answer the question about being harmful at all, you only said that you did not short it out on G1 and G2 systems.

Old post, but, to use the SK100 G3/4 in the line level plug configuration, the tip should be tied to ground/shield. The G2 works either way..
