When listening thru the headphone Jack I get lower volume than normal and lots of hiss.
I take it you looked at this, sounds like your still muted, with hiss and low output level.
The C47 Default Setting for using Headphones is to automatically mute all the Output Connectors when the Headphone Cable Plug is inserted into the C47 Front Panel HEADPHONES Jack. There are three available settings: Mute All Outputs Mute Main Output Mute No Outputs 6. Rotate the INPUT Control until “SETUP: HEADPHONES, Mute All Outputs ” appears on the Information Display. Refer to figure 26. 7. Rotate the VOLUME (ADJUST) Control to change the current HEADPHONES setting from “Mute All Outputs” to either “Mute Main Output” or “Mute No Outputs”. Refer to figures 27 and 28.Cheers George
