MUSICAL FIDELITY X-80 (01) PDF Document

The specifications for the MUSICAL FIDELITY X-80 are as follows:

Dust regularly with a soft cloth or soft brush, but be careful when using cleaning or polishing agents – they may harm the surface finish.

Input facilities: 4 pairs line level RCA connectors.

Output facilities:

2 amplifier channels via 1 pair per channel binding posts.

1 pair RCA audio outputs controlled by the volume.

1 pair RCA tape record fixed line level output.

The unit is supplied with a mains lead fitted with a moulded 13 amp plug. The wires in the mains lead are coloured in accordance with the following code:

Green and yellow: Earth

Blue: Neutral

Brown: Live

WARNING – This appliance must be earthed.

The wire which is coloured green-and-yellow must be connected to the terminal in the plug which is marked with the letter E or coloured green or green-and-yellow, or by the earth symbol.

The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.

The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.

If connecting to a BS1363 plug, a 13 amp fuse must be used.

Plug the accessory IEC mains lead into the rear panel socket, then the other end into a wall outlet.

Turn the volume control on the front panel to minimum (anticlockwise).

Press the POWER button on the MUSICAL FIDELITY X-80 amplifier – the blue power LED on the front panel will light indicating that the unit is ready for use. However, for about six seconds no sound will be heard from your speakers, and the red mute LED will be lit, confirming initial mute action.

Select the required audio input source by pressing the < or > function button on the front panel one or more times.

Alternatively, direct access can be obtained by pressing buttons 1, 2, 3 or 4 on the remote control. In either case, a corresponding blue indicator LED on the front panel will light to confirm your choice.

Now adjust the volume control to obtain the preferred sound level.

To record, simply select the required source with the up or down input selector button on the front panel, or directly from the remote control. This source will now be routed to the MUSICAL FIDELITY X-80’s TAPE RECORD output for recording by the external tape deck.

You will still also be able to hear the selected source through the loudspeakers.

Note: Adjustment of the volume control has no effect on the recording level.

All input, output and power connections should be made with the mains power switched OFF.

The MUSICAL FIDELITY X-80 has four pairs of “line level” inputs controlled by the internal volume setting. They all have the same input sensitivity, and are therefore suitable for use with any source component having an output of at least 300mV.

The four left and right socket pairs on the rear panel are marked INPUT 1, 2, 3 and 4, corresponding with the blue function indicator LEDs on the front panel.

Connect the left and right outputs from your audio components to each of the four sets of RCA sockets to suit your own order of preference.

Connect the MUSICAL FIDELITY X-80’s TAPE RECord output sockets to the line input sockets of your tape deck.

Connect your loudspeakers to the pairs of terminals on the back panel marked as LEFT and RIGHT SPEAKER outputs. Note: the combined load impedance must not be less than 4 ohms.

The MUSICAL FIDELITY X-80 amplifier has its pre-amplifier output available from RCA sockets on the back panel marked PRE-OUT, and is controlled by the volume adjustment. This is to allow “bi-amplification” using suitable external amplifiers and crossover networks to power the speaker drive components separately, giving noticeable improvement in clarity, imaging and bass weight.

In this arrangement, typically the MUSICAL FIDELITY X-80’s speaker outputs are used to drive the speaker’s “tweeter” (high audio frequencies), and an external stereo amplifier drives the “woofer” (low frequencies). The MUSICAL FIDELITY X-80’s PRE OUT RCA sockets would therefore be connected to the input of the external “woofer” amplifier in this example.

If you are in doubt about bi-amplification, please contact your dealer for advice.

Only connect the MUSICAL FIDELITY X-80 Integrated amplifier to a mains outlet having the same voltage as marked at the back of the unit.

Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is switched off.

Position the mains lead and signal interconnects where they are not likely to be walked on or trapped by items placed on them.

Do not use near water, or place water-filled containers on the amplifier, for example, flower vases or potted plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform your dealer.

Do not place the unit near heat sources such as radiators, direct sunlight or other equipment. The case of this amplifier can run at high temperatures – operate the unit in a well ventilated area, and do not touch the cabinet sides or top after periods of use at high output power.

Do not remove covers or try to gain access to the inside. There are no internal user adjustments. Unauthorised opening of the equipment will invalidate any warranty claims.

There are fuses inside the MUSICAL FIDELITY X-80 amplifier. In the unlikely event that one blows, refer the unit to your audio dealer. Do NOT try to replace the fuses yourself as this will invalidate the warranty.

Buttons on the remote control with blue-grey surround enable main functions of the amplifier to be operated from a convenient distance. As the remote control uses an invisible infra-red light beam, the transmitter must be pointed directly towards the receiver window on the front of the amplifier, without visual obstruction between them.

Pressing button numbers 1, 2, 3 or 4 selects a corresponding amplifier input.

Pressing the MUTE button mutes the SPEAKER output and PRE-OUT sockets, but has no effect on the TAPE OUT sockets for recording. To show that the amplifier is muted, the red LED on the front panel lights. Press the MUTE button again to cancel mute function, and the red LED will go out.

Pressing the volume-up or -down buttons on the remote handset will advance the motorised volume control in the required direction. This action also cancels the mute function.

If the range of the remote control greatly decreases, replace the batteries with new ones. Do not mix old and new batteries – two are required, size LR03 or AAA, manganese alkaline type.
