  • XO2 and XO3: Low Jitter CD Clock Oscillators
    Mounting instructions for: XO2 and XO3: low jitter CD clock oscillators Congratulations! You just bought a high quality, low jitter master clock oscillator. This document gives guidance to mounting and connecting it in your CD player. Introduction XO2 and XO3 are equal, except the reclocking option for XO3. XO2 and XO3 S Need to be supplied from a DC voltage of 9 to 35V, approximately 30mA. S Generate a new clock, which needs to be fed to the input of the original oscillator XO3 additionally needs: S to be fed with the original SPDIF signal (generated by the decoder chip) S the newly generated SPDIF signal to be connected to the original, or new digital output Mounting Mounting your XO is not that difficult. However some experience is needed to: S recognise and locate components S find specific connections and IC pin numbers S measure voltages using a multimeter S careful soldering of small parts If you feel lack of skills and or experience in some of the above listed subjects, please ask someone else to support you. Know your connections What is on the PCB XO, heart of the circuit Low noise adjustment - do not touch ! Supply (9-35Vdc/30 mA) SPDIF in Clock out SPDIF outputs The supply and SPDIF in (XO3 only) and clock out (XO2 and XO3) are already equipped with wiring. The supply wire may be extended using normal gauge wire, the others may not. If longer wiring is required, the use of coax is advised. Please contact me. Guido Tent can be contacted for questions and orders at: [email protected] 1 How to connect XO2 or XO3 in your player General Read these full instructions below, before starting any work.

Tighten nut to value on label. attach BD-2HLS to paddle. the BD-2HLS. 847.325.7825 OR VISIT WWW.REMKE.COM/MELNI MELNI BD-2HLS THE SMARTER CRIMPLESS CONNECTOR. Traditional electrical connector methodology is based on crimping, using a device to conjoin two pieces of metal by deforming one or both of them in a way that causes them to hold to each other. This requires multiple lugs and specialized dyes, each one manufactured for a specific cable size. The process is lengthy and intricate, requiring precise tools to secure the connection, such as hydraulic or mechanical crimps that are expensive and hard on the installer’s back and shoulders. Though this practice is time consuming, expensive and hazardous, it has been the accepted process for years. But all it takes is one idea to change everything. Introducing the BD-2HLS Melni Crimpless Connector. The BD-2HLS is a mechanical connector that can replace existing commercial mechanical and crimp-style connectors. Its crimpless installation design and spiral insert technology simplifies the connection process making it safer, easier and less expensive. A revolutionary innovation, the BD-2HLS is redefining the electrical industry. While traditional 2-hole lugs are non-range taking, the Melni BD-2HLS accepts anything between 2/0 AWG and #2AWG, spanning a large range of cable and wire sizes, and drastically reducing installation time. The BD-2HLS is all that’s required for a variety of electrical applications - having multiple lug sizes and specialized dies on hand just isn’t necessary anymore.

  • The Future of Audio
    The Future of Audio ■Audio is a cultural treasure nurtured over many years Ever since the dawn of audio technology, there is an ongoing debate whether the sound of audio equipment should be as transparent as possible or display a characteristic of its own, much like a musical instrument. Whichever side of this argument one favors, it is a fact that the reproduction chain from the microphone to the loudspeaker has come a long way. The accumulation of technology has made it possible to increasingly eliminate colorization, resulting in the sound that we have today. But this fact notwithstanding, there is practically no speaker that sounds exactly like another, nor is one amplifier exactly the same as another. Even products using digital technology have their own particular sonic characteristics. Audio technology has evolved to a very sophisticated level. However, the sound of two pieces of equipment may differ, even if their measurement data are the same. This indicates that measurement technology has not yet advanced to duplicate the full depth of human sensory perception. This uncharted territory is where the joy and creativity of audio is born. Paradoxically, the ideal state of audio equipment is one where the equipment itself disappears, allowing listeners to fully immerse themselves in the music. With regard to an amplifier, this means stepping up the level of the recorded signal and correctly delivering it to the loudspeakers without introducing distortion. However, this is easier said than done, and so far the only means of determining whether the speakers are being correctly driven by the amplifier is a subjective evaluation by listening to the sound.
