Can I connect a the line output of a device to JAM?

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.

What is a line-matching transformer? – Connecting a microphone to JAM

A Line-matching Transformer is an adapter with a female XLR connector on one end and a male 1/4” connector on the other. This transformer converts the low-impedance signal of a microphone to high-impedance for connecting to a device like JAM. In this process, the transformer is providing additional gain for optimal signal level.
