Installation Precautions

Your new X-PRE 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-PRE. Retain this guide for future reference.

• Do not use the X-PRE near water.
• Keep the X-PRE away from heat sources such as radiators.
• Only use the mains adaptor provided. The use of other adaptors could seriously damage your X-PRE.
• Place all connecting cables where they are not likely to be walked 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 subjected 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-PRE will not be covered under warranty if it has been tampered with. There are no adjustments 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.
• True to the X-PRE’s design aim of maximum sonic fidelity the X-PRE is a minimalist design with only essential facilities included.
• The X-PRE has four line-level inputs (labelled 1 to 4) suitable for use with all line level components (such as CD, Tuner, Tape machines etc.) and one set of line level outputs all situated on the back panel. All connections use RCA/Phono sockets.
• Each of your line level sources should be connected to an input on the back of the X-PRE and then the X-PRE’s output connected to the input of your amplifier system.
• For the best results we recommend that you use Musical Fidelity X-LINX “No-Nonsense” interconnect cables for all connections.
• Once all connections are made, turn the volume control to minimum and plug in the supplied mains adaptor. Allow a couple of minutes for the valves to warm up and then slowly advance the volume control and sit back and enjoy the music.
• The X-PRE has been designed to be left on indefinitely.
