STARTING
. . . .
Press the POWER button on the X-Pre V3.
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.
If PHONO input was selected when
previously powered off, there will be an
additional muting period of about 10 seconds
before sound can be heard.
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, 3or 4on 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.
TAPE RECORDING
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
X-Pre V3’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.
OPERATION .

.FACILITIES .
REMOTE CONTROL
Buttons on the remote control with blue-grey surround enable main functions of the pre-
amplifier to be operated from a convenient distance. Remaining buttons on this universal
handset are for use with other Musical Fidelity products, and have no effect on the X-Pre V3.
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(PHONO), 2, 3or 4selects a corresponding pre-amplifier input.
Pressing the MUTE button mutes the OUTPUT sockets, but has no effect on the TAPE REC
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 turn 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. Do not dispose of used batteries in a fire.
