Introduction

Connections

Thank you for purchasing the X-A200, 200 watt monobloc power

amplifier.

We sincerely hope that it will bring you many years of listening

pleasure.

Installation Precautions

Your new X-A200 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-A200. Retain this guide for future reference.

nn Do not use the X-A200 near water.

nn Keep the X-A200 away from heat sources such as

radiators.

nn 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-A200 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.

All connections should be made before the mains lead is plugged in

and the unit switched on.

The X-A200 is a mono power amplifier, two are supplied for stereo operation, further units can be used if required for multi channel surround sound systems or for bi-amping etc.

The X-A200 can be used with a preamplifier or any line level source which has a volume control. We highly recommend the matching X-PRE or 'Nu-Vista' Class A Tube Preamps available from Musical Fidelity as an excellent choice.

Connect your pre-amp or other line level source to the phono input on the back panel marked "Line Input". For the best results we recommend that you use Musical Fidelity X-LINX "no-nonsense" interconnect cables for this connection.

Connect your loudspeaker to the loudspeaker terminals situated on the back panel marked "Loudspeaker Output"

Once these connections are made, plug in the IEC type mains lead and switch on the unit.

Bi-Amping

The X-A200 has a "Loop Out" facility to allow for easy bi-amping of speakers with bi-wireable crossovers. In this kind of set-up typically one X-A200 is used to drive the tweeter (high frequencies) and one to drive the woofer (low frequencies) of each loudspeaker enclosure. Thus in this example four X-A200s would be required for a stereo pair.

Taking the left channel connections first, the pre-amp's (or other source's) left output is first connected to the first X-A200's line input and then that X-A200's loop output is connected to the second X-A200's line input, both X-A200s will now be driven from the same left channel signal. The first X-A200 can now be used to drive the woofer and the second, the tweeter of the left channel loudspeaker.

Repeat this process for the right channel.

If you are in any doubt about bi-amping, please contact your

dealer who will be able to help and advise you.
