Send & Receive
These controls are used to set the send level to the pedals and return path level back into the EXTC. These are normally set to optimize the signal-to-noise ratio.
Polarity Reverse
Lets you adjust the polarity of the wet signal path and bring it into phase with the dry signal when they are being mixed together.
Blend Control
Adjusts the wet-dry mix between the original unprocessed signal and the EXTC’s effects loop.
EFX Loop A & B
Used to select between loop-A or Loop-b. Combine them together in series for added fun!
Power
15VDC power connection for the external power supply.
1/4" Jacks
Separate send and receive ¼ jacks used to connect guitar pedals to the EXTC.
XLR Output
Balanced line-level output for runs to 1000' (300m) without noise.
XLR Input
Balance input, connects from output to your recording system to the EXTC-SA.
1/4" TRS Connectors
Parallel connectors with XLRs also enable the EXTC to be used with unbalanced sources.
Transformer
Provides isolated send path to the effects to help eliminate hum and buzz caused by ground loops.
Class-A Buffer
100% discrete class-A buffers for optimal signal flow and natural tone.
Mil-Spec PCB
Full ground plane for noise-free performance, double-sided for durability.
