Helix Floor/Rack/LT
Inputs
Guitar in: Auto impedance unbalanced TS, the impedance will be determined by the first block in the signal chain. (This is a setting that can be adjusted in Global Settings)
Aux In: 10k ohm unbalanced TS
Returns: 1Meg unbalanced TS (instrument mode)/10K unbalanced TS (line mode)
Outputs
L and R Main Out: Impedance-balanced TRS
Sends: Impedance-balanced TRS
Dry (Helix Rack only): Impedance-balanced TRS
HX Effects
L and R Main In: 1Meg unbalanced TS
L and R Main Out: Impedance-balanced TRS
Sends: Impedance-balanced TRS
Returns: 1Meg unbalanced TS (instrument mode)/10K unbalanced TS (line mode)
Note:
Although all the outputs use TRS jacks, they are not true balanced outputs. They are only impedance-balanced.
· A true balanced output would have the tip and ring driven with (out-of-phase) audio signal. The outputs on HX Effects are only driven on the tip.
· However, because they are impedance-balanced, you can still get some common-mode rejection of external noise sources (i.e. power line hum) if a TRS cable is used to connect the HX Effect outputs to a device with balanced inputs.
