Netgear M4250 AV Switch Renew Program x Giesemann OCXO Edition

Audiophile are welcome to approach us for details on modification. The below is an example of modification we done for one customer recently.  

Why it is important to use OCXO Master Clock for Network Switch?

  • This is a night and day difference, and Master Clock unlock the full potential on Network Switch 
  • Giesemann Clock is the heart of any digital audio system. It sets the tempo of all the digital pieces of audio equipment in a audiophile system.
  • Based on ultra high precision, the Giesemann clock OCXO is extreme low in phase noise in 1Hz and 10Hz interval. It brings the pivotal timing accuracy that enable DAC, Music Streamer and any audiophile network switch products equipped with a SYNC input of Master Clock to function optimally.

The GCSM will be powered 12V DC with arrays of LT3045 Regulators for OCXO module. The power module will be enhanced with exotic Floyt Bioploar Audio Capacitor x 2.  

What is the special when we design the power section for Giesemann Clock Sync Module (GCSM) ?

  • Single 12V, a universal DC voltage to power the modules. 
  • By using LT3045s in parallel to spread the current, it is designed for very high PSRR.
  • The power section will equiped with Four LT3045 in parallels to ensure Ultra High PSRR (Power Supply Rejection Ratio), this ensure the high ability to remove power supply ripple, if any, on the input external power supply 
  • This ensure highest Audio performance on OCXO with lowest derivation on Phase Noise and Allan Derivation
