POD Express Input and Output Specs
POD Express/POD Express Bass/POD Express Black
Inputs
Guitar In: 1Meg Ohm Impedance unbalanced TS
Outputs
Left/Mono output = 680 Ohm Impedance-balanced TRS
Right output = 680 Ohm Impedance-balanced TRS
Headphone Left/Right = approx. 2ohm (designed to drive headphones from 12.8ohms to about 2k)
Note:
Although all the outputs use TRS jacks, they are not true balanced outputs. They are only impedance-balanced.
Output voltage for the Pod Express is limited to +7dBv. Slightly less than other Line 6 gear, this is due to the POD Express being designed for battery use.
