This takes some pressure off the laptop ports as it offers the full amount of current to each port on the hub. The Maschine Mk2 requires roughly 480mA, ranking it with the large group.Ĭonversely, some USB hubs come with their own power supply, aptly referred to as “powered”. Point to keep in mind: even though a device might appear physically small, it doesn’t disqualify it as powerful. This type of hub works fine if you have a few modular pieces of kit that don’t draw a lot of current, but a more substantial controller will require its own port on the laptop. If you plug in a large controller with a built-in audio interface requiring somewhere around 450 to 500mA (think Traktor Kontrol S4, Pioneer DDJ-SX2) with a smaller modular device needing 100 to 150mA (eg Traktor Kontrol X1) you’ve probably overloaded that system, causing drop-outs, error messages, and general unreliability. For instance, many USB ports output 500mA (milliamperes) of power. While unpowered options such as the one you tried provide you with extra ports, they share the same amount of current from a single USB on your laptop. I have faced some freezes and weird hard drive behaviour.” Digital DJ Tips says:įor USB, the biggest issue you have to consider is power. The problem is that my MacBook has only two USB plugs, and even then you sometimes cannot connect more than one device as this can cause issues. Sigmar Muuga, a member of our Platinum Facebook group, asks: “Hey folks, do you know if there is some good USB hub for DJs? I have tried those €20 hubs but they seem to not work… some weird errors with controllers and hard drives all the time. A high quality powered USB hub will offer far greater reliability for DJs than a cheap, unpowered variant.
