Introduction Thank you for purchasing the X-DAC. We sincerely hope that it will bring you many years of listening pleasure. The X-DAC uses some of the latest in CD technology to pro- vide a genuine upgrade to the performance of your CD player whether you are playing standard or HDCD disks. The X-DAC uses an 18 bit Burr-Brown "Co-phase" DAC which combines bitstream conversion for the lowest bits and R-2R multibit for the higher bits, subjectively this gives both the low level detail resolution and smoothness of bitstream with the solid bass response and timing of multibit. The special HDCD compatible digital filter used incorporates 8 times oversampling (which allows a simple and phase-coherent analog filter), digital domain de-emphasis and auto- matic decoding of HDCD encoded disks. This is a new way of recording CD's that gives improvements in dynamics and detail resolution. Your X-DAC is fully compatible with this process and will automatically detect if a CD disk is HDCD encoded and then perform the correct de-coding, in this mode the HDCD indicator on the front panel will light up. Installation Precautions Your new X-DAC is designed and built to provide trouble-free performance, as with all electronic devices it is however necessary to observe a few precautions. Please ensure that you have complied with these before you connect the power to your X-DAC. Retain this guide for future reference. n nDo not use the X-DAC near water. n nKeep the X-DAC away from heat sources such as radiators. n nOnly use the mains adaptor provided. The use of other adaptors could seriously damage your X- DAC.n nPlace all connecting cables where they are not likely to bewalked on or trapped by items placed on them. This Hi-Fi product has been tested to ensure that its operation will not be adversely affected by normal background levels of R.F.I. (Radio Frequency Interference). It is possible that if the unit is sub- jected to abnormally high levels of R.F.I. the unit may not perform as expected. In the unlikely event of this happening please contact Musical Fidelity's service department. Do not remove any covers, the X-DAC will not be covered under warranty if it has been tampered with. There are no adjust- ments within. Please refer all service work to an authorised Musical Fidelity agent. Connections All connections should be made before the mains adaptor is plugged in. The X-DAC is easy to connect into your system. Simply con- nect a digital output from your CD player (or other digital source) to one of the X-DAC's digital inputs. The X-DAC has both optical and electrical type digital inputs, you may use either. Then connect the X-DAC left and right outputs to a line level input (e.g. CD or AUX) on your amplifier system. Once these connections are made plug in the mains adaptor, the "Lock" LED should light to show that the X- DAC has detected a valid incoming digital signal and one of the sample frequency LEDs should light (44.1kHz for CD, 48kHz for DAT etc.) The X-DAC has been designed so that it may be left on indefinately. The X-DAC has two sets of outputs you may use either of these to connect to your amplifier. For the best results we recommend that you use Musical Fidelity X-LINX "no-nonsense" interconnect cables. Further improvements in sound quality can be gained by using a Musical Fidelity X10-D valve line stage between the X-DAC outputs and the inputs of your amplifier - contact your dealer for details.
