TEAC CG 10-M master clock generator, black

The CG 10-M is a master clock generator that delivers extremely accurate clock signals, enabling D / A converters to operate at the highest quality.It is well known to the audiophile community that the clock signal is the basis of any digital signal conversion.The converters use digital signals such asPCM, with extreme accuracy, is broken down into tens of thousands of parts per second along the time axis.If this fundamental time axis fluctuates during the digital-to-analog conversion process, rendering the same analog waveform as the original is much more difficult.For DSD audio signals that operate in the Mhz range, this is even more true.Therefore, it is very important that the clock is as accurate as possible, especially when processing high-resolution files that are converted with ultra-high sampling, such asDSD at 22.5 MHz or PCM at 768 kHz.The heart of the master clock generator is a crystal oscillator which is housed in a controlled temperature box inside the "oven" in order to keep it operating at its best and most stable while the temperature is crystal oscillation is in the most ideal range.Since temperature greatly affects the accuracy of the crystal oscillator, minimizing temperature fluctuation and keeping it at an ideal level is critical to the accuracy of the clock generated.Built into the CG-10M, the TEAC Reference OXCO gave up oscillation to reduce frequency fluctuations due to temperature change. This oscillator (OCXO for short) produces an extremely accurate 10 MHz clock with only +/- 3 ppb frequency temperature characteristics. and +/- 0.1 ppm frequency accuracy with the current frequency range.The instrument panel on the front of the device gives a continuous visual indication of the status of the internal crystal oscillator. The CG-10M has 4 gold plated 50 Ohm BNC connectors, allowing up to 4 simultaneous devices such as USB DAC, AC or SACD player to be connected capable of receiving a 10MHz reference clock. All circuits of the CG-10M, from the power supply unit to the output amplifier buffer amplifier, are completely isolated to prevent cross interference when multiple devices are connected to the BNC inputs.By incorporating a buffer amplifier into each circuit, the waveform of the signal is not distorted even if the clock generated is divided between several devices. The front panel instrument shows the stability of the crystal oscillator during operation.As the temperature in the "oven" containing the oscillator reaches an ideal level for clock signal generation, the "oven" power consumption decreases and the instrument points toward zero, thereby signaling to the user that the digital processing of the connected device is already extremely accurate to 10 MHz. is controlled by clock.The instrument is backlit, adjustable or even completely off.The oscillator is usually stable after 2 minutes of power-on, but at least 10 minutes are required to reach the ideal state. A high-capacity toroidal transformer provides continuous, stable power to the device, which greatly contributes to maintaining clock generation efficiency and resulting in high precision operation.The CG-10M footrest is a TEAC patented "Pin-Point".These legs consist of two separate metal parts in an integrated housing.The upper part is fastened to the housing, which ends in a pin and the lower part of the foot depends on it.There are two legs on the front of the device on two sides and one on the back, so the support is stable even on uneven surfaces.Pin-Point device feet help maintain clock oscillation accuracy by minimizing vibration and resonance.As a result, mid- and deep-range washes, spatial mapping and fine detail reproduction are improved.v
