There are predominantly 3 different types of isolated output power supplies on the market.
- Individually Isolated Outputs. These are mostly linear design power supplies that have separate individually insulated/isolated grounds for
output wound within the transformer. This is how our FX Power Source 8 is designed and the type of isolation guitarist have come to expect when purchasing an isolated output power supply.
- Grouped Isolated Outputs. These typically also have true isolation, but the outputs are isolated in groups. Another words if outputs 1-4 and 5-8 are isolated as a separate groups. The only isolation that exists is between the two groups. Outputs 1-4 would not be isolated from each other and outputs 5-8 would not be isolated for each other.
- Advertised as Isolated but are not isolated. Those who advertise these as isolated justify it by following up the term Isolated Short Circuit / Overcurrent Protected somewhere in there description, features or specs area. The average cost of these are typically well under $100.00. Plain and simple, these are not truly isolated output power supplies.
If you don’t have a noisy pedals in your chain you can probably get away with a non-isolated output power. Our Power Source 10M and Compact Power Source 6 both feature regulated and filtered outputs with over voltage protection which work well for those without an inherently noisy set up and can save you some cash.
