This unit is supplied in the U.K. with a mains lead fitted with a moulded 13 amp plug.
If, for any reason, you need to cut off this plug, please remove the fuse holder and dispose
of the plug safely, out of reach of children. It must not be plugged into a mains outlet.
The wires in the mains lead supplied with this appliance are coloured in accordance
with the following code:
Green and yellow..............Earth
Blue...............................Neutral
Brown................................Live
WARNING - This appliance must be earthedAs the colours of the wires of the mains lead of this appliance may not correspond with the
coloured markings identifying the terminals in your plug, proceed as follows:
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
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.
WARNING:
Any modifications to this product not expressly approved by Musical Fidelity
who is the party responsible for standards compliance could void the users
authority to operate this equipment.BEFORE SWITCHING ONPlug 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).
STARTING. . . .
Press the POWERbutton on the 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 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 correspon-
ding blue indicator LED on the front panel
will light to confirm your choice.
Now adjust the volume control to obtain
the preferred sound level.TAPE RECORDINGTo record, simply select the requiredsource with the up or down input selectorbutton on the front panel, or directly from
the remote control. This source will now
be routed to the X-80s TAPE RECORD
output for recording by the external tape
deck.
You will still also be able to hear theselected source through the loudspeakers.Note - adjustment of the volume control
has no effect on the recording level.SAFETY INFORMATIONOPERATION

but as with all electronic devices it is necessary to observe a few precautions:
Heed all warnings shown on the back of the product.
Only connect the 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, who should then check the unit before further use.
Entry of liquid into the amplifier is dangerous, and may cause electric shock or fire hazard.
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.
Refer all service work to an authorised Musical Fidelity agent.
NOTE: Unauthorised opening of the equipment will invalidate any warranty claims.
There are fuses inside the 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.
Dust regularly with a soft cloth or soft brush, but be careful when using cleaning or polishing
agents - they may harm the surface finish.
The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected
or damaged by lightning. For protection of your audio system during electrical storms, remove
the mains plugs and disconnect any aerial lead.If after-sales service is required, to help your dealer identify the X-80 Integrated amplifier pleasequote the serial number located on the rear panel of the unit.
RADIO FREQUENCY INTERFERENCE (R.F.I)This product has been tested to ensure that its operation is not adversely affected by normalbackground levels of R.F.I., and that it does not itself generate excessive amounts of interference.However, if a problem persists, please contact your Musical Fidelity agent.All input, output and power connections
should be made with the mains power
switched OFF.
INPUT CONNECTIONSThe 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, 3and 4, corre-
sponding 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 X-80s TAPE RECord out-
put sockets to the line input sockets of
the your tape deck.CONNECTIONSGENERAL ADVICEOUTPUT CONNECTIONSConnect your loudspeakers to the pairs of
terminals on the back panel marked as
LEFTand RIGHTSPEAKERoutputs.
Note: the combined load impedance
must not be less than 4 ohms.
PRE-AMPLIFIER OUTPUTThe 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 X-80s
speaker outputs are used to drive the
speakers tweeter (high audio frequen-
cies), and an external stereo amplifier
drives the woofer (low frequencies).
The X-80s PRE OUTRCA sockets
would therefore be connected to the input
of the external woofer amplifier in this
example.
If you are in doubt about bi-amplifica-
tion, please contact your dealer for
advice.
