Truetone 1 SPOT Pro 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.

1 SPOT Technology

Inside look at the 1 SPOT Pro CS111 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.

Dimensions

133 x 88 x 30mm (5.24 x 3.46 x 1.18”); 488 grams (1.075 lbs.) - weight and dimensions of power supply only, not including cables or packaging.

Input Voltage

12Vdc 4.0A. External power supply (included with XP8-PS) must have a 5.5x2.1mm barrel plug, center pin positive. The XP8 is also designed to be powered directly from the output on the back of a 1 SPOT Pro CS11, provided the total current load connected to the XP8 is 2.5A or less.

Cables

The 1 SPOT Pro XP8-PS includes an assortment of DC cables. 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):

• (2) DC26 (5.5x2.1mm barrel plugs; 26” (660mm) – Purple
• (4) DC18 (5.5x2.1mm barrel plugs; 18” (457mm) – White
• (2) DC12 (5.5x2.1mm barrel plugs; 12” (305mm) – Yellow

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).
