G25U Esoteric master clock generator and PCM digital audio up-converter
“
If you own any digital source that can output PCM audio signals, the G25U can provide
an instant upgrade for your entire CD/DVD collection through master clock re-timing
and/or through digital audio PCM up-conversion, both at a very affordable price!”
G-25U functional descriptions:
The G-25U contains a highly accurate, internal crystal oscillator known as a
“Master
clock.
” This “clock” reduces system noise and digital artifacts (digital jitter), dropping the
noise level between a DAC and a digital transport to less than 1/100th of non-
synchronized devices. The master clock also re-times the synchronization between the
DAC and transport, providing highly accurate digital audio signals for improved analog
decoding. A more accurate master clock results in higher accuracy in reading and
decoding digital data. This adds extraordinary ambience, imaging and clarity to a digital
audio signal by removing inter-component jitter.
To utilize the Master clock function, you will need a separate DAC and transport with
“Word sync” or “word clock” input on the DAC. For a combined DAC and transport, a
connector for “Word sync” or “word clock” input is required.
The G25U “clock,” allows precise digital playback and enhances existing systems. This
is realized by linking all digital playback components that allow external time
management together under the control of just one master clock. Literally, all digital
devices are operating to a single heartbeat, maximizing the merits of digital audio.
Even if your connected component has no “Word sync” or “word clock” input, the G-25U
improves accuracy by re-timing a PCM data stream. This is done by using a digital audio
input on the G25U, and connecting it between
any audio/video device equipped with a
digital PCM audio output
(CD/DVD players, digital tuners, satellite receivers, high
definition cable boxes, etc) and the digital input of your receiver/preamp/processor. If
your
digital players allow the user to select the digital output format between “Stream”
and “PCM” for Dolby Digital, DTS or other formats, then the G-25U can be inserted in
the digital stream to re-clock, re-time and “clean-up” this PCM digital transmission.
Note: Your receiving device (processor, pre-amp, receiver, et cetera) must also be able
to accept and decode Dolby Digital or DTS PCM data.
An example of use would be a pre-amp processor or separate components with coax or
optical digital input, and an inexpensive CD or DVD player with coax or optical digital
PCM output. In this situation, you can use the G25U to re-time the data stream by
connecting the CD/DVD player digital audio output to the G25U input, then connecting
the G25U digital audio output to your pre-amp processor. This often results in a smother,
more transparent signal.
