Various users have complained about humming in their music output when they connect the amp to 1 SPOT power supply because as soon as they shift to another power supply, the hum is eliminated. While it’s possible to replace the power supply, it’s more cost-effective if you just separate the signal-carrying cords and power cords. If you’re a touring musician, or even if you just play at the local pub regularly, you know how important it is to have road-worthy gear. No worries with the 1 SPOT Pro. The housing is all steel, with cleverly designed vents that should keep out the accidental beer spill, should that ever happen. And the CS6 is completely sealed for extra protection.

Line 6 modeling pedals (DL-4/MM-4) may be powered by outputs 8-11, but will also require the CL6 converter. You may optionally use output 12, as the power input of these pedals can use 9Vac or 9Vdc. If more 9Vdc pedals need to be powered, an MC5 daisy chain (sold separately) may be plugged into any of the 9Vdc outputs depending on mA draw. For adding one more pedal, use the included MC2 cable. Many germanium based fuzzes and Octavia-style pedals will require the use of the CYR adaptor to reverse the polarity to center pin positive.Battery Clip Converters, (2) 3.5mm (1/8”) Converters and an L6 Converter for Line 6 modeling pedals

If you have connected 1 SPOT to the pedalboard and it seems like the pedalboard is losing the signals or response is slower, the culprit is the battery. In particular, a weak battery causes slow and delayed connection, so just recharge the battery for a few hours before you use the power supply. 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 In most cases, it doesn’t support the pedals that have their own switching power supplies, huge digital processing sections, and DC current drains. On the other hand, it works fine with an analog pedal but make sure there is reverse polarity protection. The 1 SPOT is the original 9V DC adapter that only takes up one spot on your power strip. With the ability to handle up to 1700mA, the 1 SPOT can power your entire pedalboard. Line 6 POD or M13 cannot be powered by the 1 SPOT Pro CS12, even on the 9Vac output. The milliamp draw is too large for those units.That’s because it needs an isolated output, and 1 SPOT doesn’t provide an isolated output. In this case, the only solution is to replace the power supply with a new one. Secondly, you need to avoid the ground loop. The ground loop usually occurs when you connect multiple devices to one outlet and are using multiple effects. If you have connected this power supply, but it’s causing interference to TV reception, you need to relocate or reorient the antenna to optimize the reception. For pedals with high milliamp draws such as Strymon, please utilize outputs 1 or 2 that produce 500mA each.

Last but not least, if the power supply is constantly overheating, it can also cause connectivity issues. If that’s the case, it’s recommended that you disconnect the power supply from the outlet and let it cool down. In addition, you should never use extension cords and power strips to connect 1 SPOT. However, you must hire an electrician to replace the capacitors because they store voltage charges for a long time, which means you might get electrocuted if you don’t follow the correct process. Lastly, you need to be extremely particular about the outputs. You can even use the 1 SPOT anywhere in the world without a voltage converter because it automatically converts voltage worldwide. No need to worry about AC hum interfering with your sound either... the 1 SPOT is one of the quietest power sources you can buy. The 1 SPOT is the original 9V pedalboard power supply that only takes up one spot on an outlet strip or wall outlet. It solves an annoying problem that people have complained about for years, and does so with quiet, reliable performance!That’s because if the pedal has a higher milliamp draw, you should opt for outputs ranging from 8 to 11. However, to use outputs 10 and 11, you must install a CL6 converter for proper polarity.

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 CS12, you need to know the following: This is a great power supply for musicians since it works well with the pedalboard as long as you are careful about the number of pedals. However, the connectivity and performance issues can be easily fixed with cable replacement. As far as tube replacement is concerned, you can get the compliant tubes from the music shop to make sure the amp works well and produces sound. However, if these steps don’t work, you must replace the patch cables.

Truetone 1 SPOT Slim 9V DC Adapter Features:

Overdrives or fuzzes that sound/feel better at lower voltage should utilize output 7. Set the dip switch to the “on” position, and adjust the mini-pot on the face of the unit to the desired voltage, anywhere from 4-9Vdc. The overheated and damaged tubes can lead to sound issues, so just inspect the amp for such tube issues and replace the damaged ones. On the other hand, if the amp seems overheated, you only need to let it rest to ensure it achieves room temperature.
