Now you have one heartbeat from the G25U running all devices at 1ppm. This makes the G25U the master clock-out device, with the DAC set to clock/word in and connected to its transport set to word/clock in. Now the D/A converter becomes slave to the G25U and the transport becomes slave to the DAC. For example: use the G25U as master clock to the input of a DAC. To reclock a transport, you need the word sync or clock sync input (or be able to loop a clock sync signal between a DAC and transport). But that is retiming the digital data, not relocking the transport.

"In a nutshell, retiming occurs within the data stream when PCM is input and output via our DSRL元 circuit. That meant inserting brother G between transport and DAC just as one would any other anti-jitter (or anti-digital as it were) box. One had to merely enter/exit the G25U through its digital i/o ports and presto. What Mark seemed to be adding now was that simply by using any of the conventional digital i/o ports (single-ended, balanced, Toslink) found on all digital separates, one could access the G25U's reclocking oscillator. I had believed that without Esoteric's BNC-carried reclocker terminals duplicated on a non-Esoteric machine, you couldn't avail yourself of its internal master clock function.

Thus far, I'd labored under a misapprehension.
#Atomic word clock free#
From any PCM source, DSRL元 provides a smoother output virtually free of jitter that may have been present in or caused by the signal path itself." Since DSRL元 can lock accurately to any sampling frequency between 28 and 54kHz, input signals from such digital sources as satellite broadcasts (32kHz), CD (44.1kHz) and DAT/DVD (48kHz) can be converted to an output signal with improved time axis accuracy. Input data is stored momentarily in RAM, then output with the time axis controlled by a quartz crystal generator. "DSRL元 is our 3rd evolution of a digital servo-ratio-locked loop which helps to reduce the generation of jitter in the signal path for digital transmission. It's a niche no doubt but consumers have bought the G25U, from our research, about 30% of the time for the clock sync and/or DSRL元 retiming and about 70% of the time for the upconverter. In fact, digital cable and network customers are some of our best users, in addition to conventional CD, DVD player or FM tuner customers with PCM digital outputs. "As for upconversion, consumers who have bought the G25U for that alone tell us that they use it with players that have a PCM output but no upconversion. Most players are running from 30-50ppm or worse. 3 to 1 is very subtle but once you take out the G25U after a day or two, you should hear the benefits. Many (even high-end) players don't publish their jitter spec at all. All of our video-capable units are rated +/-10ppm so the G25U makes good sense with a dramatic impact. Those are the only two ways to use that master clock sync feature. Or you need to route it between a transport and DAC. However, to use the clock sync function with any other playback device, you need clock-in or word-in. DSSR元 drops the noise floor of any form of jitter by up to 1/100th below its original level. This circuit reduces injections of jitter noise into a digital PCM data stream because it regenerates/retimes that stream thought the upconverter and internal crystal clock prior to output. More importantly, he will benefit due to Esoteric's DSSR元 circuit. "It is possible that if an existing playback device with upsampling has a defeat option for that circuitry, the user may benefit from the G25U's upsampling.
#Atomic word clock serial#
Unless Mark was to tell me that serial upsampling - putting two upsampling circuits of the same conversion frequencies behind one another - had unexpected benefits. That defeats the other half of brother G.'s feature set. To boot, many dedicated CDPs already sport their own internal 24/192 upsampling. That seems to render the reclocking feature mute. After all, the majority of digital machines lack clock-link inputs. While I still had Mark Gurvey's ear, I asked what most existing G25U customers leash to it.
