Electronic User Guide
Congratulations on your purchase of the Mission 529. This product is designed to be intuitive to setup and operate, and to provide many years of trouble free service. However, we recommend that you take a few moments to read through this User Guide in order to get the best possible experience with your new pedal.
What is the 529?
The Mission 529 is the worlds first USB power converter for effects pedals and similar devices. The 529 converts any USB power supply such as a wall charger, rechargeable battery pack, or computer USB port into 5 isolated 9V effects pedal power outputs. You can chain two 529’s together via USB link, to power up to 10 pedals.
The 529 works with the standard USB power sources that you already have. At home, or in the studio, outside, or while traveling, the 529 can power your pedal board from a portable battery pack, phone charger, or laptop computer.
The 529 is just 1″ deep, weighs just 4oz, and can be carried in a pocket or bag. It will easily fit under small form factor pedal boards such as the Pedaltrain Nano and Metro, making it ideal for fly rigs.
What's in the Box?
1 x Mission 529 Power Converter
1 x 5V 12W Wall power supply
1 x 10′ USB cable
1 x 3′ USB cable
5 x 3′ 2.1mm power cables
1 x 10,000mAh rechargable Lithium Ion battery pack (optional)
Each 529 can support a maximum of 1200mA (4 x 150mA, and 1 x 500mA). This is dependent on the USB power source. The 529 is provided with a 2A USB plug-in power supply which can power up to two 529’s. When using a plugin power supply or battery other than those supplied with the 529, check the specifications to determine the power output.
Most USB plug in power supplies, and batteries are rated for 1A, or 2-2.4A. When using a 1A power supply the outputs will be limited to a total of 1000mA (1A). This is usually enough for one digital pedal, and three or four analog pedals. When chaining two 529’s together to power 10 pedals then you will most likely need a 2A supply.
Note, that when daisy chaining two 529 units together via a USB cable, the two 500mA outputs will be common with the USB, i.e. they will not be isolated from each other. All 150mA outputs will, however, remain isolated. If noise from digital pedals connected to the 500mA outputs is present in such a configuration, it is recommended to power these pedals from an alternate supply, or to power each 529 separately.
The 529 can be powered from a USB port on a desktop or laptop computer. The power output will depend on the specific computer. These are commonly limited to 500mA. Check the specifications for your computer. If the USB port is limited to 500mA, this will be the maximum the 529 will be able to provide to the pedals. This is normally enough for 4 or 5 analog pedals.
One of the most useful features of the 529, is it enables powering of effects pedals from a standard portable USB battery pack. There are hundreds of different batteries available at a wide range of capacities and price points.
The 529 is available with an optional Mission 529 Verified 10,000mAh battery. This battery is ideal for powering a pedal board, and is our preferred battery pack for the 529. See the battery feature list on this page for details.
Most USB battery packs should work with the 529. Mission has tested other battery packs. Look for the Mission 529 Verified logo when choosing a battery pack. The logo indicates Mission has tested that battery for compatibility and performance.
The length of time you can run your pedals on a battery depends on the total power consumption of the pedals, and the capacity of the battery. We have provided some charts for guidance on this page.
Connect the USB In on the 529 to the included USB wall charger using a USB A-B cable. When USB power is present the LED’s next to the outputs will illuminate blue.
Check the current draw of the pedals you are going to connect. The user guide or manufacturers web site will normally have this information. Pedals with a current draw is less than 150mA can be connected to any output. Pedals with greater than 150mA current draw should be connected to the 500mA output.
Connect your 9V pedals to the appropriate power outputs using the supplied power cables. Note that all outputs are center pin negative. Use an appropriate polarity reversal adapter, if using center pin positive pedals.
Check that your pedals are functioning correctly. If there is a fault on the pedal or the output, the LED on that output will turn off.

Introduction to the 529
Battery Feature List
The Pro bundle version includes a 529 and a Mission validated APC 10,000mAh rechargeable USB Lithium Polymer battery.
Battery charge time from empty to full charge is approximately 8 hours using a 2.1A USB charger connected to the charging port (the USB micro connector in the middle). The LED’s on the front of the unit should light to indicate charging.
Once charged, quickly press the green button on the side to turn the outputs on. The LED’s will light and indicate charge state. Hold the green button in for several seconds to turn the outputs off. The LED’s will go out to indicate the unit is switched off.
It is recommended to connect the 529 to the 2.4A output to provide the maximum power to the 529. A second device such as a phone can be simultaneously connected to the 1A output. Total current from both outputs cannot exceed 2.4A.
Does the 529 contain a battery?
There is no battery inside the 529. You can fix it permanently to a pedal board without having to remove it to recharge or replace the battery. Any 5V USB external battery pack can be connected to the 529 via the USB input.
Can the 529 be powered from laptop?
Yes, you can connect the 529 to a laptop or desktop USB port. The available power will depend on the specific computer. Most computer USB ports are limited to 500mA, but this is still enough for several analog pedals. If your computer has a charging port, then that may provide more power.
Will it fit under a Pedaltrain?
Yes, the 529 is just 1″ deep and will fit under Pedaltrain boards including the Nano without any modifications.
Can I connect two 150mA outputs in parallel?
Yes, in most cases this should work. If you have a device that requires more than 150mA, and you are already using the 500mA output, you can connect two 150mA outputs in parallel using a suitable cable. This will provide a single output with a current limit of 300mA, from two 150mA outputs.
Can I daisy-chain several pedals to a single output?
You can connect multiple pedals to a single 9V output on the 529 to power more than five pedals. If you do this, keep in mind that you cannot exceed the current limit of the single output. If you connect more than one pedal to one output, add the current draw for each pedal, and make sure the total does not exceed the current limit for the output. For example. If you have three pedals that draw 50mA each, that will be the maximum you can connect to a single 150mA output.
Note also that pedals daisy-chained to a single output will not be isolated from each other, which, depending on the pedals, may increase noise.
Is the 500mA output isolated?
The 500mA output is isolated from the 150mA outputs. When using a single 529, if you connect five devices to the five outputs, they will all be isolated from each other.
The 500mA output is common with the USB output. If you daisy-chain two 529’s together via the USB output, or power a device such as a phone or USB powered pedal from the USB out, these will be common with the 500mA outputs. The 150mA outputs will still all be isolated.
Can I connect a low power pedal to the high power output?
Yes. The current limit is just the maximum that output is rated to provide. A device will only draw the current that it needs, so you can connect a low power pedal such as one that draws 20mA, to the 500mA output, and it will still only draw 20mA.
If the connected device or cable has a fault that causes a short-circuit, it could draw more current and damage the device. The 529 has short circuit protection to help prevent this. If the output is short-circuited, the 529 will shut down the output and the LED will go out. The faulty device or cable should be removed immediately.
Is the 529 quieter or noisier than an AC/DC power supply?
When comparing with high quality isolated AC supplies, in most cases system noise should be about the same, or less. Using a battery can sometimes result in less noise due to the isolation from AC common mode noise, and exclusion of ground loops.
When compared to low cost daisy-chain power supplies the noise level will often be much less since isolated supplies are not subject to digital noise being passed into the signal chain through a common DC return path.
Can the 529 power an Eventide H9?
Yes, the 500mA output on the 529 is suitable for powering an Eventide H9. Note that because the H9 uses a center pin positive, 2.5mm connector, you will need a suitable cable such as the Mission 2.5mm adapter cable.
It is NOT recommended to daisy chain additional pedals to the 500mA output when connecting the H9.
