1 SPOT PRO: The Original Studio-Grade Power For Your Pedals

XP8-PS

The 1 Spot Pro XP8-PS is just like the XP5-PS, except it has 8 outputs instead of 5. Each output provides 9Vdc of studio-clean power and can handle at least 500mA of current draw per output. Measuring 133x88x30mm (5.24x3.46x1.18”) and weighing only 459 grams (16.19oz or about 1lb), it can be easily attached to a pedalboard using only Vel-Cro. Because of its low profile, the XP8 can be mounted under most pedalboards, or be used as a pedal riser on top of a board. With 2 linked input jacks, you can power a second XP8 or XP5 by simply connecting a DC cable..

The 1 SPOT Pro Story

“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.” - Bob Weil (Founder & President - Truetone)

1 SPOT Technology

Inside look at the 1 SPOT Pro CS11 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 triple filtered 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 many 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 (for example), the output labels add up to 1900mA total. That means the total current draw of all your pedals should be less than 1900mA.

Multiple Voltages

Multiple Voltages (CS Series only)

We recognize that not all guitar pedals run off 9V. That’s why all 1 SPOT Pro models have outputs that can put out 9Vdc, 12Vdc or 18Vdc. The CS12 even has a variable voltage output for old-style fuzz pedals, and a 9Vac output for certain Line6 and Digitech pedals. And if you need to change the voltage of an output, Truetone also makes inexpensive converter cables to help you. There’s the Voltage Doubler, which does exactly what its name says, and the 18V to 9V Converter... which also does what its name says. They don’t have the most clever names, but they get the job done!

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.

Energy Efficient

Prior to the 1 SPOT, musicians either used one linear power supply (a.k.a. wall wart) per pedal, or used batteries. Both solutions for powering pedals were very inefficient with energy, with batteries also contributing greatly to the toxic waste stream. In 2000, we pioneered the use of switching power supply technology to alleviate this condition in an economically-, energy- and environmentally-conservative way. The 1 SPOT power supply was designed to replace many such external power supplies and/or batteries simultaneously. It provided plenty of power with a very low noise level to successfully meet the needs of musicians. By offering musicians a solution that was more cost effective and energy efficient, and moving the market away from linear transformer-based power supplies to switching power supplies, Truetone has caused the saving of thousands of watt-hours per musician per year. Utilizing a more comprehensive switching power supply solution, the 1 SPOT Pro sets a new level of efficiency for power bricks, while still meeting the needs of musicians for low noise operation, even in severe conditions where the pedals themselves may generate interfering noise.

Can The 1 SPOT Pro Power My Pedal

Can the 1 SPOT Pro power my pedal?

That question can best be answered by looking at the following questions and notes…

Which output and settings do I use for my pedals?

It is important for you to know the power requirements for your pedal. For every pedal that you are going to power via the 1 SPOT Pro XP8-PS, you need to know the following:

What is the voltage required by the pedal?
Does the pedal require AC or DC voltage?
What is the polarity of the pedal? (Center pin positive or negative.)

These questions can usually be answered by:

1. Inspecting the pedal itself near the power jack.
2. Referring to the owner’s manual.
3. Checking online, or contacting the manufacturer
4. If your pedal can be powered by a 9Vdc battery, it can be powered by one of the 9Vdc outputs.

Notes on using certain pedals with the 1 SPOT Pro XP8-PS:

• The vast majority of pedals use 9Vdc. Check your pedals to make sure they require 9Vdc, as that is the voltage on all outputs of the XP8.
• Eventide Factor pedals and H9/H90 may be powered with the addition of the CL6 converter (sold separately) for proper DC jack tip size and polarity.
• Line 6 M9 will also require the CL6 converter plug (sold separately).
• Line 6 M5 may be powered without a converter plug.
• Line 6 HX series and POD Go require a C2.5 converter (sold separately). Please note, although these pedals can be powered by a single output, we recommend using 2 outputs combined using a Truetone MC2 cable (sold separately) to split the current load.
• If additional analog 9Vdc pedals need to be powered, a Truetone Multi-Plug cable (sold separately) may be connected to any of the 9Vdc outputs depending on mA draw. If additional pedals need isolation, you may purchase another Truetone XP8 or XP5 expansion box which connects to the second input of the XP8. The XP5 has 5 isolated and filtered outputs, while the XP8 has 8.
• Pedals that do not have a power jack, yet are powered normally by a 9Vdc battery, may be connected using a CBAT converter (sold separately).
• Digitech Whammy: Version 5 or Whammy DT may be powered without a converter plug. Versions 1-4 cannot be powered by an XP5.
• Radial Tonebone 15Vdc pedals can only be powered by using a Truetone Voltage Doubler cable (model TVD – sold separately), and using a Reverse Polarity Converter (model CYR – sold separately).
