One option is to use a transformer with three outlets. 16Vac/16Vac/48Vac

Another option is to use two separate transformers, each with their own outlets, 16Vac/16Vac and a seperate 48Vac transformer


The FULL VPR can be configured by using a 2x15/18Vac transformer with 100VA capacity to provide +16Vdc and -16Vdc. We highly recommend a TRIAD VPT30-3330. Additionally, a separate 48V transformer can be used to power the 48V rail. Alternatively, a transformer with 3 outlets, 16VAC/16VAC/48VAC, can be utilized. This configuration enables the powering of a full rack with up to 11 effects in a 500. With its versatile compatibility, the FULL VPR offers flexible options for powering various combinations of equipment within the 500 series.
