Related Questions and Answers

Q: 1. What are the dimensions of this unit?

A: It is 4.6" wide x 4.7" deep x 1.75" high.

Q: 2. I know this has been asked in a different form, but I just need to make sure. I intend to connect this to a laptop that will be sleeping 99% of the time when not in use, and then plug it in a power conditioner that I switch off when not in use. My question is if this hub will 'disconnect' from the laptop when powered off, and will not transmit buss power from the sleeping laptop, effectively keeping things like an SSD drive or buss powered midi keyboard ON? To be clear, I want this disconnect to happen. Hope this made sense. Thanks!

A: Yes, when the host computer would sleep the access to the powered device is cut. Due to the device needing to be accessed to start its function.

Q: 3. I purchased this in November 2020. Nice sturdy piece of hardware, but some USB devices to not seem to work with it. The light above the slot does not light up, and the device is not recognized. For example, my Epson Perfection 4870 Photo scanner. It's not that the slots are not functioning, because I have moved working devices around to double-check. Does this hub maybe not work with devices that are too old?

A: It is entirely plausible that some older devices would not be compatible with this hub.

Q: 4. What is the length of the A & C connectors and what is the total length of the cords on the AC adapter?

A: 1 meter.

Q: 5. Would all the ports power a bus powered audio interface, or only the charging port? And would it still power the interface without the computer connected?

A: It would depend on how much power your audio interface consumes. The red port can provide up to 2.4a of power. The hub does not have to be connected to the wall for power. However, the devices you connect may or may not be power by the hub.

Q: 6. Will this work as a headphone amp/ dac as well as microphone amp? Am wanting to improve sound from laptop to headphones

A: Do not understand what you mean with dac . If the purpose is to improve the laptop output, I suggest you look for something else, as this pre-amp was conceived for high quality Analog to Digital Conversion (ADC) from microphones. The headphone level you've got with this pre-amp is just for monitoring purposes during recording, thus the output level is quite comparable to what's provided by a laptop.

Q: 7. Will this work with Windows 10?

A: Not compatible with Windows 10.

Q: 8. I'm getting really low monitoring through headphones on this. even turned up to 10 and balanced to hear the preamp only. Does anyone else have this issue?

A: I haven't heard of this issue per-say. The first thing I'd look at would be the impedance specification on my headphones. If it's on the high side, I'd consider getting a headphone amp, or headphones with a lower impedance.

Q: 9. Does this hub come with all cables necessary or are additional accessories required to use this device ?

A: I agree with the others who have answered: The hub came with a power supply and USB3 cable, which is all I need to make it work with my computer.

Q: 10. Will it handle two (2) self powered USB Laser Printers, and 1 external Backup Drive as the sum total of the peripheral load?

A: I doubt it. It fried my external drive after a week, it would unmount while files were being transferred. After the 4th or 5th time it happened the drive died. Have not been able to get the drive to work since. I returned the hub. i wouldnt plug anything into this hub unless you can afford to lose it.
