It is possible to connect a line output to JAM, however the output must be unbalanced.
JAMʼs input can be driven up to 14dBu unbalanced and it is recommended that the output device be set to a -10dBv reference output level.
If the output level is +4dB referenced, it is recommended to be cautious with the amount of output gain being sent to JAM. (6-10 dB below maximum output level). Examples of line output sources may be, mic preamps, mixing consoles, outboard signal processing equipment, etc.
