I need a real solution and answer as to what's wrong with my code100 amp head! Is there any solution to not hearing sound clear thru headphones..... otherwise I'm sending this back and will try another Code 100 head but if the second amp does not work then I have wasted 1 whole year waiting for this amp and it Still is not resolved..... Marshalls reputation is at stake!!!!!!! Please help me
Regarding your CODE100 amplifer, when designing an amplifier with a headphone socket there are tight constraints due to health and safety with the level of output of the headphone socket, normally adjusting the volume and gain and occasionally tone you can get a good sound through the headphones. We would recommend using a patch as the level of volume will need to be greater when using headphones with regards to the speaker sound.
I use my Marshall Monitors with the CODE 100H. Headphone levels are more than loud enough jamming with streaming over bluetooth or directly with an mp3 player. Try increasing the volume on the music source. Just keep the Master Volume down on the amp until you equalize the volumes so you don't blow out your ears.
