Few subjects arouse as much excitement as a nice hearty discussion of Rane's use of external power supplies. We have done this long enough that it is a good time to review why.
The idea began with the realization that it was unbelievably wasteful and totally unnecessary for every product to have separate AC line transformers...and diodes...and capacitors...and regulators. The alternative was what the instrumentation guys did: use one power supply for an entire rack of equipment. Our vision was that no one would build power supplies into signal processing units; alternatively, the pro-audio industry would have specific manufacturers that only built power supplies: big ones, little ones, fat ones, skinny ones, rack-mount, desk-top, stand-alone ones, etc. (but no wall-warts-wall-warts bite.)
In our vision, one power supply would give you a system power switch, it would sequence your equipment on and back off; and it would provide all the safety, isolation, balanced AC power, audio-friendly grounding, ground-fault protection, monitoring lights and meters you need. But our vision was not to be.
We tried. From April, 1988 until October, 1989, Rane worked through the AES trying to establish a remote power supply standard, but to no avail.
So we modified the vision, called it RAP for Remote AC Power and made a successful go of it alone.

Note: Products shipped with the RS 2 will operate just fine with an RS 1.Note: All new Rane products have been redesigned with internal power supplies that will operate anywhere 100-240 VAC is available, so the RS 1 only exists for legacy products.
Rane warrants its products to be free from defects for 1 year from the date of purchase.
