Helix Floor/Rack/LT/HX Effects Input and Output Specs


Guest

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.
