Shunt USB or HDMI conditioner

USB transmission was developed for connecting computer peripherals, certainly not for transporting digital audio. Frequently, the computer’s high-frequency noise of the power supply is superposed on the data lines. Although the data can be corrected due to buffers and asynchronous transmission (redundancy), the jitter of the physical signal is very high. Still a long way from really jitter-free.

These are the two main problems:
  • High-frequency noise of the computers' power supply is superposed on the data lines, interfering with digital and even analog signals after your DAC.
  • Jitter is too high, the original signal will not pass bit-perfect. It doesn't matter much what type of metal and purity conductor is used for the transmission. As long as no active corrective circuitry is used, noise problems will stay more or less the same.

  • Telos Macro Quantum USB active noise cancelling works just like a triaxial stabilizer for your camera. By using a detection circuit to detect noise and take countermeasures (sending the original noise exactly out of phase), a relatively stable USB transmission channel is obtained.

    The Telos Engineering Team uses two special ICs to detect and compensate. After plugging in Macro Q, it connects with the data lines and the special IC will detect random noise and create a dynamic noise trap, achieving the purity of the real transmission signal by reducing losses in the digital signal path.

    Macro Q is able to generate an exact copy of the noise of any digital device connected to the USB, perfectly phase shifted to yield a noise sum that's nearly zero. This will tremendously expand dynamic range of the USB data lines, thus eliminating errors and jitter.

    The specially treated connecting cable is an integral part of the system and has to be used in order to get the best results. 

    To make the Macro Q an even more effective device, a Schumann generator has been incorporated. This results in a cleaner data transmission of which the effects can't be missed. You will notice a less "digital" sound, with more calmness and details.

    The improvement in sound quality is nothing short of spectacular! Review by John van Polen
    The main source in my high end stereo system is a Marantz SA-10, which I only use as a CD-player. So the digital inputs and outputs are left untouched. As open inputs and outputs may capture electrosmog or reflect noise from the player itself, I closed these inputs and outputs with dedicated plugs. That surely yielded some improvement soundwise. Just the other day, I replaced the Jitterbug from Audioquest in the USB-A input with the Telos Macro Q. The improvement in sound quality is nothing short of spectacular! The system now obviously sounds more relaxed, natural and effortless. More information is conveyed, there is more separation between musical instruments and yet the music sounds more pleasant. I could never have imagined that the USB-option on this precious machine would lay such a burden on its sound quality … . Anyway, I have a significantly better CD-player now! I guess the Telos Macro Q is a must for any “high end guy” owning an essential component with an open USB-A input … . (Posted on 7/29/2022)
