Impulse Response Settings
Knob Parameter Description
1 IR Select
Selects one of the 128 available IR locations. If a location con-
tains an IR, the inspector header displays its name; otherwise,
it reads "<EMPTY>."
2 Low Cut
Filters a portion of the IR's bass and/or treble frequencies,
which can help remove rumble and/or high-end harshness.
3 High Cut
4 Mix
Blends the IR signal with the dry signal passed through the IR
block. When set to 0%, the path bypasses the IR completely.
When set to 100%, the entire path is fed through the IR, and
no dry signal is heard.
5 Level
Adjusts the overall output level of the IR block.
Send/Return
Each of the Helix four sends and returns can be used independently, or used together
as an FX loop.
FX loops let you dynamically insert your favorite external stompboxes (or rack eects)
into any location in your tone.
NOTE: Each send and return pair can be set for instrument (for inserting stomp-
boxes) or line-level operation. See "Global Settings > Ins/Outs"
NOTE: Each return can be used only once in a preset. For example, if you add
a Return 1 block (or assign one of the input blocks to Return 1), Return 1/2, FX
Loop 1, and FX Loop 1/2 items will all appear grayed out in the model list, as they
also utilize Return 1.
Send Settings
Knob Parameter Description
1 Send
Adjusts the level sent to your external devices.
2 Dry Thru
Adjusts the level of the signal passed through the Send block,
independent of the Knob 1 (Send) level. Normally, this should
be set to 0.0dB.
Return Settings
Knob Parameter Description
1 Return
Adjusts the level received at the Return jack.
2 Mix
Blends the Return signal vs. the dry signal passed through the
Return block. When set to 0%, the path bypasses the Return
completely. When set to 100%, the entire signal is fed from the
Return, and no dry thru signal is heard.
FX Loop Settings
Knob Parameter Description
1 Send
Adjusts the level sent to your external device.
2 Return
Adjusts the level received at the Return jack.
3 Mix
Blends the FX loop signal vs. the dry signal passed through
the FX Loop block. When set to 0%, the path bypasses the
FX loop completely. When set to 100%, the entire path is fed
through the FX loop, and no dry thru signal is heard.
4 Trails
Trails O: An external stompbox would be instantly muted
when the FX Loop block is bypassed. Trails On: An external
delay or reverb stompbox would continue to decay naturally
when the FX Loop block is bypassed.
