TEAC CG10MAB Reference 500 Series Master Clock Generator - Black

TEAC CG10MAB Reference 500 Series Master Clock Generator - Black

The master clock generator CG10MAB provides an incredibly accurate clock signal so that digital-to-analogue converters (DACs) can operate at their peak efficiency. The fact that the clock signal serves as the cornerstone of all digital signal processing is well acknowledged among audiophiles. As an illustration, the time axis of digital signals like PCM is split into tens of thousands of parts per second. It is far more challenging to reproduce an analogue audio waveform that is similar to the original if the fundamental time axis shifts throughout the D/A conversion process. This is especially true for DSD audio signals because they operate at MHz speeds along the time axis. For the reproduction of digital audio signals, especially Hi Res files that use extremely high sampling rates like DSD 22.5MHz or PCM 768kHz, it is crucial to have a clock signal that is as accurate as possible. A crystal oscillator, or "oven," which maintains the highest and most stable performance under an optimal temperature environment for crystal oscillation, is at the centre of the master clock generator. An extremely precise 10MHz clock signal is produced by this oven-controlled crystal oscillator (OCXO), which is within 3 ppb of frequency temperature characteristics and 0.1 ppm of frequency precision. The front panel's exquisite analogue gauge provides a constant visible indicator of the condition of the internal crystal oscillator.

The CG10MAB master clock generator optimises the performance of USB DACs, network players, CD players, and other gadgets using 10MHz clock input.

A Fresh Reference - Oven-Controlled Crystal Oscillator (OCXO)

In order to produce an accurate clock signal, it is crucial to minimise temperature variations and keep it at a desirable level. This is because temperature has a significant impact on the crystal oscillator's accuracy. To lessen oscillation frequency fluctuations brought on by temperature changes, the CG10MAB makes use of a cutting-edge oven-controlled crystal oscillator called the TEAC Reference OCXO.

A Clock With The Highest Level Of Precision

The TEAC Reference OCXO enables the CG-10M to deliver an ultra high-precision 10MHz clock signal to USB DACs and digital players that is within 3 ppb of frequency temperature characteristics and 0.1 ppm of frequency precision. Every OCXC case has a distinct laser-engraved serial number and the TEAC Reference OCXO logo as evidence of the meticulous quality check carried out during the manufacturing process.

Connectors For Four BNC Clock Outputs

To provide clock signals to numerous devices, four gold-plated BNC connections (50 ohms) are offered. It is possible to connect up to four 10MHz-capable devices at once including SA-CD players, network players, and USB DACs.

Circuit Design That Is Independent And Isolated

To avoid cross-interference when numerous devices are attached to the BNC connectors, every circuit in the CG10MAB is totally isolated, from the power supply section to the buffer-amp at the output stage. Each circuit needs a buffer-amp to prevent signal waveform degradation when many devices share the generated clock signal.

Oven Status Gauge For Tracking Clock Stability

The unit's OVEN STATUS analogue gauge, a TEAC trademark in recent years displays the stability of the crystal oscillator when it is operating. The gauge points to zero, indicating to the user that the digital processing on the linked device is now regulated by an incredibly accurate 10MHz clock signal as the temperature of the oven containing the crystal oscillator rises to the perfect temperature for accurate clock generation. The CG10MAB gauge has a dimmer control and a backlight that may be totally turned off. It is a backlit type.

Power Transformer With A Toroidal Core

The effectiveness of the important clock generation and its subsequent high-precision output are substantially enhanced by a high-capacity toroidal-core power transformer, which continuously supplies a constant, stable current.

Patented "Pin-Point" Feet With Three Positions To Provide Absolute Stability

The CG10MAB uses TEAC's 'Pin-Point' feet which are patented. These cleverly combine two independent metal pieces in a single housing. One is a basin-shaped base that hangs down from the spiked part with a flange-shaped cup to facilitate installation, and the other is a spiked top that is affixed to the bottom of the chassis. For exceptional stability even on an uneven floor, three "Pin-Point" feet are employed, two at the front and one at the back. The three "Pin-Point" feet reduce vibrations and resonance, which helps increase the accuracy of clock oscillation. This, in turn, lessens muddiness in the mid- and low-frequency range, boosts fine sound detail, and improves the soundstage.

With A Sturdy Full-Metal Chassis And An A4-Size Footprint

The CG10MAB was created to complement the popular Reference 500 series. It has a small, A4-size footprint, aluminium panels, and a sturdy metal chassis that shields it from electromagnetic noise.
