Truetone 1-Spot Pro CS-7 Power Supply

The world's first power brick with switching power supply technology.

The Truetone 1-Spot Pro CS-7 is a versatile power supply that can power most pedals on the market, whether they are 9, 12 or 18V. The seven outputs mean you can power a reasonably sized board without the power taking up a huge footprint on your board. Truetone have included mounting brackets for Pedaltrain boards and made the power input worldwide, so as long as you've got the right kettle lead you can take your 1-Spot Pro CS-7 on a world tour!

For many years, Truetone has made musicians’ lives easier with the 1 SPOT, the original compact pedalboard power supply. It works so well that a lot of musicians never felt the need to get one of those brick-style power supplies, and we here at Truetone didn’t see the need for those either, even though they were quite popular. Bob Weil, founder of Truetone, explains:

“A lot of people over the years had told us that we should make a power brick. Even some of my own staff urged me to do it, but I didn’t want to for two reasons. First, I knew the 1 SPOT could power just about every pedal out there, so I didn’t see the need. Second, I didn’t want to make just another knock-off of someone else’s power brick. If we were going to make one, we were going to do it our way and have features that nobody else could offer. As pedal designs changed and it became more common for digital pedals to require isolation and for others to need something other than 9Vdc, I finally saw a reason for us to design a power brick.”

“It took 3 years and lots of experimentation, but we were finally able to design a 1 SPOT Pro, using our own proprietary technology to give musicians all the features they need for today’s pedalboards. The original 1 SPOT still works great for most musicians, but for those who need more power and versatility, the 1 SPOT Pro fills the need perfectly.”

1 SPOT Technology… what does that mean and why should I care? Technically, it’s switching power supply technology, which is very different than what anyone has ever put inside a power brick. Normally, you would find just a big transformer and a handful of small electronic components inside a power brick… old tech that hasn’t changed in decades and has a lot of limitations. We took the same switching power supply technology found in our famous 1 SPOT and scaled it up to make the 1 SPOT Pro models. With much more space to work with, we were able to completely eliminate noise, provide total electrical isolation between outputs, create multiple voltages, and still give you the ability to use it anywhere in the world.

A major benefit of using a switching power supply is that it can handle far more current (power being pulled out of it) than any transformer-based power supply. Although we had to put power rating labels on each output to satisfy certification agencies (yes, we actually certified these, unlike most companies), the outputs can generally handle far more than the label shows. For example, you can connect a 300mA pedal to a 200mA output, without causing any problems. With a transformer-based power supply, you can’t get away with that. The important thing is to not exceed the total of all the labels. With a CS7, the output labels add up to 1900mA total. That means the total current draw of all your pedals should be less than 1900mA. That total current rating is roughly double the current load of the most common power brick, for a lot less money.

Multiple voltages

While most pedals still run off 9VDC, not all of them do. That’s one of the main reasons why we finally decided to design the 1 SPOT Pro. With the CS7, you get one output for 18VDC and six at 9VDC, with four of those switchable to 12VDC. Need another 18VDC output? No problem… just get a Multi-Plug 2 cable (MC2) and run both pedals off that one outlet… most boosts and drive pedals don’t mind sharing an output anyway. Don’t need the 18VDC output at all? No problem… just get Truetone’s 18V to 9V Converter cable (V189).

Worldwide input voltage

Just like with the original 1 SPOT, and your laptop power supply and phone charger, the 1 SPOT Pro uses switching power supply technology which allows you to use it anywhere in the world. The CS12 has an input voltage switch on the back, which switches voltage only for the 9VAC output, since that output does use a toroidal transformer. The rest of the outputs on the CS12, and all of them on the CS7, don’t care what the input voltage is.


The 1 SPOT Pro includes a generous assortment of cables and converter plugs. The cables are of various lengths, color-coded for easy cable management and with right angle plugs on the pedal end.

Power cables (all are center pin negative polarity):
(4) DC18 (5.5x2.1mm barrel plugs; 18” (457mm) – White
(3) DC12 (5.5x2.1mm barrel plugs; 12” (305mm) – Yellow

Converter Plugs:
(1) CL6 – (5.5x2.1mm barrel input, 5.5x2.5 barrel output; reverse polarity)
Green – for Line 6 DL4/M9/etc. and some Eventide pedals.
(1) CYR – (5.5x2.1mm barrel input, 5.5x2.1 barrel output; reverse polarity)
Red – reverse polarity converter
(1) C35 – (5.5x2.1mm barrel input, 3.5mm male output; tip positive)
Black – 3.5mm (1/8”) plug converter
(1) CBAT – (5.5x2.1mm barrel input, Black battery clip output) Connects to batter clip wires inside pedals that do not have DC jacks. Do NOT connect to a battery!

Pure Isolation

Since pioneering the first switching power supply for musicians, the original 1 SPOT, we’ve gained many years of experience in creating very low noise power for pedals. When we started designing the 1 SPOT Pro, the first multiple output switching power supply, we worried a lot about how to eliminate noise completely. Isolation is part of the solution to noise elimination, but not all of it. Each output is galvanically isolated from the other to help give you pure, clean, noise-free operation of your pedals. However, we also provided an additional layer of pure analog regulation, taking advantage of the greater ability of analog circuits to provide the highest possible suppression of in-band audio noise. There is an artistry involved in these designs, and it’s come at the price of decades of hard work. But all of this put together is what we call Pure Isolation.

Pedaltrain Mounting Brackets

The only power brick to include easy-to-install mounting brackets for Pedaltrain pedalboards. We even duplicated the output labels under the unit, so you can easily see which output is which, when working on your board. Yes, we thought of that too!

One Spot CS6

Multiple Pedal Power

The Truetone Spot Pro CS6 provides power for up to 6 pedals in a compact and low-profile unit, designed to fit on smaller pedalboards or be top-mounted. Each output is isolated, filtered, and free of noise giving you true professional operation in noisy electrical environments. It follows on from the 3 years of development that Truetone took to design their first power supply.

Powers Almost All Pedals

With its many different included cables and adapters, the Truetone CS6 can supply power to almost any pedal on the market. It outputs can be switched through multiple voltages, including 9/12/18v. Two outputs provide a super-high 500mA output at 9v so can be used to power your high current-draw effects pedals that would usually require their own supply.

Superior Technology

The Truetone CS6 uses a custom-designed switching power supply that can handle far more current (power being pulled out of it) than any transformer-based power supply. This gives it a max of 1600mA DC to play with; an astonishing figure from such a small and portable unit. It also allows multiple voltage inputs so provides use in different countries.
