SMSL G1 10M External Master Clock SC-Cut OCXO Quad-Channel BNC Clock

Description

Product Overview

The SMSL G1 10M Master Clock is engineered to set a new benchmark in audio timing precision. At its heart lies an imported, communications‑grade SC‑cut oven‑controlled crystal oscillator (OCXO) that delivers exceptionally low phase noise, ensuring that every digital audio sample is synchronized with nanosecond accuracy. The unit measures 9.41 x 1.5 x 3.74 inches and weighs 5.13 pounds, making it a compact yet robust addition to any professional audio environment. Four independent 10 MHz BNC outputs are driven by separate buffer stages, allowing you to connect multiple devices without cross‑talk or signal degradation. A high‑quality clock cable is included, providing a reliable link to SMSL PL200T, T2, D200, PA200, and other compatible gear. The design incorporates a Porcupine toroidal transformer and dedicated power filtering to minimize magnetic leakage and external interference, guaranteeing a clean clock signal even in electrically noisy settings.

Usage

Designed for audiophiles, recording studios, broadcast facilities, and high‑end home theater installations, the G1 master clock excels wherever precise timing is critical. Connect the BNC outputs to your digital‑to‑analog converters, DACs, or network audio players to eliminate jitter‑induced distortion and preserve the original soundstage. The clock’s low‑noise performance is especially beneficial for multi‑channel setups, where each channel must remain perfectly in phase to avoid imaging errors. Its compact desktop form factor allows placement on a rack or a dedicated shelf, while the included cable simplifies integration into existing signal chains. Whether you are mastering a track, streaming high‑resolution audio, or calibrating a reference system, the G1 ensures that timing errors are reduced to a level that is virtually inaudible.

FAQ

What is the advantage of an SC‑cut OCXO over a standard crystal oscillator?

An SC‑cut OCXO offers far superior temperature stability and lower phase noise, which translates to more accurate timing and less jitter in digital audio applications.

Can I use the G1 clock with devices that require a different frequency output?

The G1 provides a fixed 10 MHz output, which is the standard reference frequency for most high‑end audio equipment. For other frequencies, a frequency multiplier or divider can be added downstream.

How does the independent buffering of each BNC output improve performance?

Separate buffer stages prevent one output from loading or affecting the others, ensuring consistent signal integrity across all connected devices.

Is the included clock cable suitable for long‑distance connections?

The supplied cable is optimized for typical studio distances up to 2 meters. For longer runs, a high‑quality shielded coaxial cable is recommended to maintain signal purity.

What warranty and support does SMSL provide for the G1 master clock?

SMSL offers a one‑year limited warranty covering manufacturing defects, along with dedicated technical support to assist with installation, configuration, and troubleshooting.
