The 100kHz output also simplifies operation by obviating the need to change the clock-output frequency when switching between sources (CD and DVD-A, for example) or between different oversampling frequencies.

An additional output frequency of 100kHz is also available, which Esoteric thinks might become a universal standard in the future. These clock-output frequencies correspond to the common sampling rates of 44.1kHz (CD and SACD) and 48kHz (DVD). (An additional frequency is available for synchronizing PAL-based video products.) Each section has two outputs, allowing up to six products to be locked to the G-0Rb.

The G-0Rb has three separate clock-output sections, each of which can be independently set to 1x, 2x, or 4x the base frequencies of 44.1kHz and 48kHz. In fact, engaging the G-0Rb catapults the sound of the already great P-03/D-03 into another league, particularly with recordings that have a good sense of space and depth to begin with. Consequently, comparing the sound of the digital front end with and without the clock is as simple and fast as pushing two buttons.Īnd pushing those two buttons renders a staggering improvement in virtually every aspect of the music presentation. In my case, front-panel switches on the P-03 and D-03 disengage the units’ conventional on-board clocks and accept the clock from the G-0Rb. The G-0Rb’s outputs feed the clock-input jacks on a transport and digital-to-analog converter. The G-0Rb can be used with Esoteric transports and processors that accept an external clock signal, as well as with products from other manufacturers that have a word-clock input. A narrow front-panel display indicates the G-0Rb’s output frequency, which is adjustable via a row of buttons (see sidebar for specifics). The rear panel, however, reveals its uniqueness in the audio world-it holds eight BNC clock-output jacks, a BNC clock-input jack, and an AC power socket. The unit is sheathed in Esoteric’s gorgeous metalwork, matching the P-03 universal transport and D-03 digital-to-analog converter in my equipment rack. The G-0Rb looks at first glance like it could be a digital-to-analog converter. But apparently this wasn’t good enough, leading Esoteric’s Motoaki Ohmachi to create a timing device based on the element rubidium. Esoteric already has reduced timing inaccuracy (clock jitter) in its products through the use of a separate clock line between transport and processor, as well as a system in which the processor is the master and the transport a slave. That’s right-the G-0Rb is an atomic clock in your equipment rack that provides an ultra-precise timing reference for the digital-to-analog conversion process.įrankly, I thought an atomic clock with timing precision of ☐.05 parts-per-billion would be overkill. But I didn’t realize just how important it was until I heard the Esoteric G-0Rb Rubidium Master Clock Generator.

I’ve known for some time that clock-timing accuracy is essential to good-sounding digital-audio reproduction.
