For high-end audio nothing is more important than ensuring purity of signal.

Perturbations, phase-noise/jitter and poor locking ability can all interrupt the smooth flow of signal between audio modules.

Golledge’s range of products recommended for high-end audio avoid spurious resonances by using only the highest quality quartz and mounting techniques. This helps to decrease the likelihood of unwanted perturbations affecting your tuning curves or control loops.

We also offer VCXOs with wide pullability, ensuring ease of locking between audio modules.

All of our audio-recommended products also feature fantastically low jitter specifications, meaning you don’t need to worry any longer about introducing noise into the output of your DAC. We also offer ultralow phase noise OCXOs for those wanting the ultimate in clean audio reproduction.

Our expert in-house engineering department can help with any custom requirements, testing and specifications you require, if you need a custom part please get in touch, we'd love to help.
