TEAC Audio CG‑10M‑X Master Clock Generator

Unlock studio‐grade timing precision in your digital audio system with the TEAC Audio CG-10M-X — a high-precision 10 MHz master clock generator designed to drive up to four devices.

Product Description

The TEAC Audio CG-10M-X is a reference-series 10 MHz master clock generator engineered for digital audio systems seeking extreme timing stability. It features a high-performance oven-controlled crystal oscillator (OCXO) housed in a thermostatic chamber, delivering frequency temperature characteristics within ±3 ppb and frequency precision within ±0.1 ppm. 

With four gold-plated BNC outputs (50 Ω impedance, 0.5 Vrms sine wave) you can supply the same ultra-stable clock reference to up to four compatible DACs, network players or CD transports, thereby synchronizing multiple components in your system. 

In this “X” edition, TEAC has refined the output buffer amplifier circuit, power supply, and chassis mechanics — including a semi-floating top panel, Stressless three-point isolation feet and a robust full-metal chassis — all designed to reduce vibration and electromagnetic interference for clearer digital playback. 

It’s ideal for those operating systems with DACs and transports that include a 10 MHz input, especially in high-end digital chains where multiple components must lock to the same master clock for minimal jitter and maximum clarity.

Top 20 Questions About TEAC Audio CG-10M-X

What is the TEAC Audio CG-10M-X used for?
The CG-10M-X generates an ultra-stable 10 MHz clock signal that you feed into compatible DACs, network players or CD transports to improve synchronization and reduce timing variation (jitter).

What devices can benefit from the TEAC Audio CG-10M-X?
Devices with a 10 MHz external clock input (BNC) — such as high-end DACs or transports — can be driven by the CG-10M-X to improve timing fidelity.

How many devices can the TEAC Audio CG-10M-X drive at once?
Up to four devices can be connected simultaneously via the four BNC outputs.

What improvements does the “X” edition include over prior versions?
The “X” edition features refined output buffer amplifiers, improved power supply circuits, a semi-floating top panel, Stressless isolation feet and upgraded chassis design for lower noise and better sound.

Does the TEAC Audio CG-10M-X include an internal oscillator?
Yes — it uses TEAC’s Reference OCXO (oven-controlled crystal oscillator) which maintains extremely precise frequency stability.

How long does the TEAC Audio CG-10M-X need to reach full stability?
The oscillator stabilizes around 2 minutes after power-on, but TEAC recommends 10 minutes of operation for ideal condition.

What connector type does the TEAC Audio CG-10M-X use for clock outputs?
Gold-plated BNC connectors (50 Ω).

What is the output level of the TEAC Audio CG-10M-X?
0.5 Vrms sine wave at 10 MHz.

Will the TEAC Audio CG-10M-X improve any DAC?
Only if your DAC (or transport) supports an external 10 MHz clock input and operates in a system where clock distribution matters (e.g., multiple devices or chain lock). If your system lacks a 10 MHz input, it may offer no benefit.

Is the TEAC Audio CG-10M-X suitable for stereo listening systems?
Yes — particularly in high-end digital setups where precise clocking can reduce noise, improve clarity and widen soundstage.

Does the TEAC Audio CG-10M-X require a warm-up period?
Yes — at least 10 minutes is recommended for the OCXO to reach peak stability.

What power requirements does the TEAC Audio CG-10M-X have?
US version uses 120 V/60 Hz; power consumption ~15.4 W during warm-up, ~10 W when stable.

What footprint will the TEAC Audio CG-10M-X occupy in my rack?
The unit is compact (approx 290 × 84.5 × 248.7 mm) — about the size of an A4 sheet — so it fits easily into many audio racks.

Can I upgrade the firmware or functions of the TEAC Audio CG-10M-X?
No — it is a precision hardware clock generator rather than a firmware-driven device.

What isolation or mechanical design features does the TEAC Audio CG-10M-X include?
It uses three-point “Stressless” support feet and a semi-floating top panel to reduce vibrations and treat mechanical coupling.

How does the TEAC Audio CG-10M-X fit into a digital audio system?
You place the clock generator in your audio chain, power it up, allow it to stabilise, then connect its BNC output(s) to the 10 MHz input(s) on your DAC(s)/transport(s). Set those devices to accept external clock.

Do I need special cables for the TEAC Audio CG-10M-X?
Yes — you’ll need 50 Ω BNC coax cables suitable for digital clocking, of reasonable quality and appropriate length to maintain signal integrity.

What is the warranty or support for the TEAC Audio CG-10M-X?
The unit is supported via authorised TEAC dealers; confirm local warranty details.

Is the TEAC Audio CG-10M-X compatible with all brands of DACs?
Only with DACs or transports that explicitly include a 10 MHz BNC clock input. Check your component’s spec before purchase.
