tX-USBhub

  Those esteemed customers having experience of using the tX-USB and tX-USBexp products of USB host cards would have known the fact as to how much the quality of USB port affects the audio sound.

The tX-USBhub, used as connected to those devices, such as the Note PC, Mac mini and NUC board, provided with no PCI or PCI express slot, may substitute the functions of tX-USB or tX-USBexp products.

 The functions of tX-USBhub would be simply defined as USB 2.0 hub, but can be described further in detail as an “Audio USB 2.0 Hub” designed and developed solely to achieve high quality for USB audio devices employing the technologies used in the products of tX-USB and tX-USBexp, which provides the excellent sound quality unequaled and incomparable to other conventional USB hubs.

– Ultra Low Noise Regulator : Extremely low noise power supply circuit, as designed considering the noises generated from the power supply circuit itself.

– Ultra Low Jitter Clock : Super-precision clock circuit improving the sound quality by reducing the jitter of audible band most sensitive to human.

– Active Noise Canceller : Make the clock frequency vibration caused by the voltage variations and noise stable, so it produces the best sound quality.

– 2nd stage power regulator for highest sound quality

– USB port power on/off switch for highest sound quality

– USB port signal noise filter for highest sound quality

– High performance capacitor for improvement sound quality

– USB port power over current & thermal protection for safety operation

Applicable to operate connecting the USB audio devices and external storage devices simultaneously through two USB ports built in the product, allowing selection of products fitting to the operating condition out of embedded type tX-USBhubIN for installation inside of PC enclosure and external type tX-USBhubEX for standalone operation.

Also, outstanding sound quality improvement effect can be experienced using the premium quality battery based power supply available with separate purchase.

Do try and in person experience the high quality sound system produced from the new platform beyond and above the existing PC product criteria.

FAQ

Can I use both USB ports at the same time?

Recommend using 1 USB port. If you use both USB ports at the same time, it will degrade sound quality.

How different between tX-USBhub and tX-USBexp?

 The tX-USBexp and tX-USBhub’s basic concept and technique are the same ;

  Ultra Low Noise Regulator,

  Ultra Low jitter clock,

  Active Noise canceler,

  Multi stage regulator

  and also others are applied into both tX-USBhub and tX-USBexp.

 The main components used on the tX-USBhub are also the same as tX-USBexp, so their sound character and design are like a twins.

 But the main difference is that tX-USBhub is not an USB host card as like tX-USBexp is, the tX-USBhub is USB 2.0 hub , so it has 2 USB ports.

 Also tX-USBhub has more benefits than the tX-USBexp since the connection to mainboard is made by USB connector only.

 Both tX-USBexp and tX-USBhub could work with external power, and as this fact, everyone knows the good power supply such as mBPS-d2s or sPS-1000 improves sound a lot. As for the external version(tX-USBhubEX), it should work with the external power all the time so it has big merits to take good sound quality with NUC board, Note PC(Laptop), Mac or etc..

 But please consider that even though both tX-USBexp and tX-USBhub have the same techniques, concept and sound character, after all the result comes out differently depending on various circumstances as like M/B, power supply, memory, CPU, HDD, SSD…. so it can not be judged simply which one is the better one, but you can consider building the super clock(sCLK or sCLK-EX) with tX-USB series board, their combination is amazing.
