Correctly powering your old Boss pedal (ACA vs PSA simplified)

Choosing the right ability supply for your Boss pedal point can be a slightly confuse tax. In general, Boss compact pedals were designed to use one of two adaptors : ACA or PSA. Although both ACA and PSA adaptors ( and all Boss compact pedals ) use the lapp size jack/connectors as each other, their specifications and requirements are different .

If your bicycle was built before 1997 then it ‘s most likely made to use what was called the ACA adapter. Do n’t confuse this with what ‘s often called an AC adapter ( used on pedals like the Digitech Whammy 4 ) as these will fry your pedal.

The ACA adapter was made for the original Boss compact pedals back in 1977. The provide produces 12v ‘s of “ unregulated ” DC power even though the pedals were designed to run off 9v ‘s of DC office ( like a 9v battery ). This mean that the Boss designers implemented some home circuitry in their pedals to drop the voltage down from the 12vDC that the supply produced to the 9vDC that the lap needed. It ‘s authoritative to note that this circuitry only impacts the power supply input and not the battery break down.

I know what you might be thinking and yes, this was a in truth foreign way to do things. however pedals were only newly back then and they were still working out the kinks, so this is barely how it was for a few years.

The first Boss bicycle not to use this ACA system was the Boss DD-2 in 1983. due to it ‘s higher than average power requirements, the DD-2 was designed around the fresh PSA adapter which produced 9v ‘s of clean, regulated might. Boss continued using both of these power supplies side by side when designing their pedals for a few years until 1997 when they standardised all pedals and entirely used the PSA system .

so how do you know which power add your pedal needs ? first, take a look at the label underneath your pedal point for a few clues..

The first thing listed on a Boss compact bicycle tag is the exponent requirements of that pedal. The table has two column : AC Voltage and Boss AC Adaptor. The AC Voltage column gives a list of possible voltages from around the global ( 100v for Japan, 240v for Australia etc ). The Boss AC Adaptor column shows you which adapter is available in which region.

The most authoritative information to note hera is whether your bicycle is asking for an ACA-XXX or a PSA-XXX adapter. The first image you see is the label of a ACA powered Boss CS-1 Compression Sustainer, the second is a PSA powered NS-2 Noise Suppressor.

The other noteworthy places you will find information about which supply your pedal needs is on the spine next to the world power jacklight or on the box ( of a PSA pedal, ACA boxes do n’t tend to have this noted ). ​

so what happens if you use the wrong adapter ? The short answer is not a lot. Using a PSA adapter on an ACA bicycle will cause the effect to sound watery and possibly muffled. The LED will besides likely not turn on. This is all due to the fact that the power is being reduced to around 6v ‘s internally and is not enough to exponent the pedal by rights ( much like an erstwhile 9v battery would ).

To use your old Boss pedal point with a advanced might supply, there are a few options :

1) The pedals can easily be modified by bypassing the incision that reduces the voltage. This frequently only uses a single wire and can be well reversed whilst keeping the pedal 100 % original. Contact your favorite bicycle company ( which is hopefully us.. ) and they can help out with this.

2) If you ‘re using a daisy chain ( or any power supply with what ‘s known as “ common grate ” ) and have a PSA Boss bicycle in the chain then this will bypass the electric potential reduction circuitry and your pedal should function fine.

3)  Some mod power bricks have 12vDC outputs or even varying world power outputs that are capable of 12vDC. These outlets are normally perfectly capable of emulating ACA power. We use our MXR CAE might supply that has a match of variable electric potential outputs.
