[Elecraft] turn off head phone monitoring

[goldtr8 at charter.net]

Dear all,

I have my speaker output connected to a graphic equalizer to try and 
improve my  audio.

The problem is that I want to turn off the monitoring when transmitting 
so I dont hear myself in the earphones because when transmitting on 20m 
and above the equalizer is not happy and it over drives the headphones.

I turned it on this morning and now I can not find what I did so I can 
turn it off.

Thanks
Don
