Overview

Silent Angel Genesis GC 25MHz | Audiophile Master Clock

The Silent Angel Genesis GC 25MHz is a high-precision external master clock engineered for audiophile network switches, music servers and digital streaming components. Built around Silent Angel's dedicated TCXO clock architecture, advanced high-frequency filtering and low-noise power circuitry, the Genesis GC delivers a stable 25MHz reference signal for compatible high-performance digital audio systems.

Designed around the native clock frequency used by many Ethernet networking circuits, the 25MHz Genesis GC provides an external reference without requiring the frequency conversion associated with 10MHz clock sources in compatible 25MHz network devices.

Native 25MHz Clocking for Digital Audio

Many Ethernet controllers and network switching circuits operate using a 25MHz clock reference. When a 10MHz external clock is used with these circuits, additional frequency synthesis may be necessary to generate the required operating frequency.

Silent Angel's 25MHz clocking approach is designed to eliminate that conversion stage in compatible equipment, avoiding an additional potential source of phase noise and timing fluctuations.

The Genesis GC 25MHz delivers a dedicated reference signal from an independent chassis, isolating its clock circuitry from the electrical activity and shared power resources of connected audio equipment.

Advanced Clock and Noise Reduction Technology

The Genesis GC combines precision clock generation with specialized electrical and mechanical engineering.

  • Native 25MHz TCXO: Delivers a stable clock reference for compatible digital audio and networking components.

  • Direct clock architecture: Supports compatible equipment without requiring 10MHz-to-25MHz frequency conversion.

  • High-frequency noise filtering: Helps suppress unwanted electrical interference.

  • High-permeability EMI absorbers: Protect sensitive clock circuitry from electromagnetic interference.

  • Low-ripple power circuitry: Provides stable power for consistent clock operation.

  • Gold-plated BNC output: Provides a reliable connection to compatible external clock inputs.

Dedicated External Clock Architecture

Internal clock circuits operate alongside processors, networking components and other electronics that can introduce electrical interference.

The Genesis GC addresses this challenge by housing its precision oscillator in a dedicated aluminum alloy enclosure. Its independent power circuitry and noise-reduction technologies are designed to maintain a stable reference signal outside the receiving component.

The single gold-plated BNC output supports automatic 50/75-ohm impedance detection for compatibility with appropriately equipped digital audio components.

FAQs

Please read our FAQs page to find out more.

Do you price match?

Yes. We match any authorised dealer, including big-box retailers. If you find the same product at a lower price, contact us and we'll match it.

Do you offer free shipping?

Yes — free shipping on every order, with 2-day delivery available on most products. Easy returns and exchanges are included.

Where is your showroom?

We're at 6362 Alder Drive, Houston, Texas. The showroom lets you hear and compare reference-level systems in person before making any decisions. If you're considering a larger purchase or installation, it's well worth the visit.

Can I buy online without visiting the showroom?

Yes. The full product range is available through the online store with free nationwide shipping. For more complex system builds, speaking with one of our advisers first tends to lead to a better result.

Do you offer financing?

Yes. Special financing is available through the BrandSource Credit Card for qualifying purchases, allowing you to spread payments over time with no annual fee. Promotional rebate savings are also available periodically. See the financing page for full details.

Do you install systems as well as sell equipment?

Yes — installation is central to what we do. We design and install whole-home audio and video, home theaters, media rooms, outdoor audio, lighting and motorised shades, and full smart home automation.

Do you provide support after installation?

Yes. We provide ongoing service and support to ensure systems continue performing as intended — not just on installation day, but over the long term.
