High-speed USB MIDI HOST box (UMH-21) is a new generation of USB MIDI host box launched by DOREMiDi. This product has standard high-speed USB2.0, which has the characteristics of strong compatibility, fast transmission rate and high stability. The product has a firmware upgrade function and is perfectly compatible with all devices with a USB MIDI interface.
At present, there are various USB HUBs on the market, and some USB hubs cannot be used on the UMH-21. So DOREMiDi designed this product - USB HUB-4. This product (USB-HUB4) is used with the high-speed USB HOST box (UMH-21), so that the USB HOST interface of UMH-21 can connect multiple USB MIDI instruments at the same time.
1. with 4 USB expansion ports.
2. High-speed USB2.0 version.
3.With external 5V DC power supply interface.
4. Made of aluminum alloy shell.
Note: If you have other USB HUB products, we cannot guarantee that it will work with UMH-21.
But you must know that the USB HOST interface of UMH-21 only supports connecting to USB2.0 hubs with up to 4 USB expansion ports.
