This product is designed to be intuitive to setup and operate, and to provide many years of trouble free service. However, we recommend that you take a few moments to read through this User Guide in order to get the best possible experience with your new pedal.[/vc_column_text][title text=”Background” text_align=”left”][vc_column_text]The SP-25M-PRO has dual 25K outputs with polarity selection and a momentary toe switch, compatible with many devices for guitar, keyboards, acoustic instruments both live and in the studio.

[/vc_column_text][title text=”Connections” text_align=”left”][vc_column_text]The SP25M has three 1/4″ output connections. The two outputs on the left side marked OUT 1 and OUT2 are the expression pedal outputs. Connect one or both of these to the expression pedal input(s) of the device you wish to control. 1/4″ TRS (stereo) cables are required; regular TS instrument cables will not work.

Both expression outputs will be controlled simultaneously. It is not possible to switch the pedal between different outputs. For switchable outputs, the SP25M PRO Aero can be used with the Expressionator multi expression controller.

The single output on the right side marked OUT3 is the switch output. This can be connected with  a 1/4″ TS  cable to a compatible device that supports an external momentary TS switch such as a MIDI controller or multi-effect unit. The switch output may be left unconnected if it is not required.

After connecting the cables, follow the instructions in the user manual for the device you are connecting to determine if it should be enabled or calibrated for expression pedal use.[/vc_column_text][title text=”Power” text_align=”left”][vc_column_text]The expression pedal and switch functions are passive, and the SP25 PRO Aero does not require a power supply or battery. The power connection input marked 9v DC is not required in this pedal model, and a blank is installed.[/vc_column_text][title text=”Polarity” text_align=”left”][vc_column_text]There is no global standard for expression pedals; different manufacturers and products can require different types of expression pedal. The SP25M Pro Aero expression outputs are 25K Ohm TRS. These will work with many, but not all devices. Some devices will still work with a 25K expression pedal but required a reversed polarity where the ring of the TRS is connected to the potentiometer wiper.

The SP25M PRO Aero factory defaults are set so that OUT1 and OUT2 are tip to wiper. For use with ring to wiper devices, the polarity of the expression pedal may be reversed. Remove the 4 rubber feet and metal baseplate. Locate the polarity switches marked SW1 and SW2.

Factory Default
SW1 – OUT1 – Right – Tip to Wiper
SW2 – OUT2 – Right – Tip to Wiper

Setting either switch to the left position will reverse the polarity to ring to wiper on the corresponding output.

Make sure to replace the baseplate and feet after setting the polarity.[/vc_column_text][/vc_column][vc_column width=”1/2″][title text=”Safety Instructions” text_align=”left”][vc_column_text]Read, Keep & Follow these instructions
