A5 DAB/FM TUNER
DAB/FM Tuner with Remote Control
INSTRUCTIONS FOR USE
Thank you for purchasing the Musical Fidelity A5 DAB/FM Tuner.
The A5 DAB/FM Tuner uses the latest technology in Digital Audio Broadcast
receiver circuitry coupled with a high quality FM tuner, and valve output stage to
give top quality reception of both analogue and digital stations. The FM section
also features RDS and radio text
Both DAB and FM programmes are extracted digitally and up sampled to 192kHz
sampling rate which allows the DAC to give better aliasing rejection, resulting in
clearer, more decisive sound from DAB as well as FM.
The audio output uses a 6922 dual triode valve per channel to give the soothing
valve sound to all your favourite stations.
Aesthetically, the A5 DAB/FM Tuner is a perfect match for
other products in the Musical Fidelity A5 Series .
Together these components form one of the finest hi-fi systems available.
Dust regularly with a soft duster or soft brush, but be careful when using cleaning
or polishing agents - they may harm the surface finish.

GENERAL ADVICE
INSTALLATION PRECAUTIONS and USER INFORMATION
Your new A5 DAB/FM tuner is designed and built to provide trouble-free performance, 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 A5 DAB/FM tuner 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 tuner unit, for example, a flower vase
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 tuner is dangerous, and may cause electric shock or fire hazard.
Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.
Do not remove any covers or try to gain access to the inside. There are no internal adjustments or
fuses you can replace yourself. Refer all service work to an authorised Musical Fidelity agent.
Note: Unauthorised opening of the equipment will invalidate any warranty claim.
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 A5 DAB/FM tuner please quote 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 normal
background 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.

REMOTE CONTROL
REMOTE CONTROL
The upper group of buttons on the remote control enable main functions of the tuner 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 A5 DAB/FM tuner.
Equivalent buttons on the remote handset have the same functions as those on the front panel of the
unit.
As the remote control uses an invisible infra-red light beam, the transmitter must be pointed
directly towards the display window on the front of the amplifier, without visual obstruction
between them.
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 SUM-4, AAA or LR03.
Please dispose of used batteries in accordance to local regulations.

INTRODUCTION / INSTALLATION
INTRODUCTION
AUDIO CONNECTION
Congratulations on your purchase of an
A5 DAB/FM Tuner and remote control.
The tuner should be connected to a suitable
pre-amplifier or integrated amplifier input by
audio cables with RCA / phono type plugs.
These link the left and right AUDIO OUTPUT
sockets on the rear panel of the A5 DAB/FM
Tuner to the “tuner”or other suitable line-level
input sockets on the amplifier.
This tuner is is designed to bring DAB into the
realms of hi fidelity sound reproduction with
the smooth sound of valves to complement the
very latest technology DAB/FM receiver
circuit. To this end, a pair of 6922 dual triodes,
(one per channel) are incorporated into the
LINE OUT stages which themselves have
vanishingly low noise and distortion and output
impedance is low.
Do not use any amplifier sockets intended for
“vinyl” phono cartridge input, as the sensitive
circuit will overload, producing a severely
distorted sound.
Great attention has been paid to internal layout,
isolating each circuit section to prevent
possible interaction.
If desired, the unit can be attached to an
external DAC of your choice. The unit outputs
COAX and OPTICAL digital signal stream at
48kHz.
The resultant performance achieved by this
tuner is among the best in the world. It has
excellent signal / noise ratio, low distortion,
wide bandwidth, huge dynamic range and
extraordinary resolution of fine detail.
NOTE: The digital output works for both DAB
and FM bands.
AERIAL (ANTENNA)
To cater for later upgrades, both DAB and FM
are available from the optical and coaxial
digital outputs for connection to an external
DAC of your choice
For ease of installation, a tri-band aerial is
supplied with the unit. This covers the FM,
DAB II, III and L-bands and picks up sufficient
signal for most domestic purposes..
The aerial is plugged into the tri-band antenna
F connector at the rear of the unit, and should
be securely fastened by tightening the nut.
However, if FM stereo background noise is
obtrusive, radio text is corrupted or DAB cut-
out is experienced, or unit is to be used in a
fringe area, a rooftop DAB and FM aerial may
be required, please contact an approved aerial
contractor with good local knowledge.
INSTALLATION
Position the tuner on a stable, horizontal
surface where there is no risk of it being
knocked, or subjected to vibration.
All input, output and power connections should
be made with the mains power switched OFF.
CLEANING
Before cleaning the tuner, switch off power at
the mains switch and remove the mains plug
from the wall socket.
Clean the cabinet and remote control unit using
a moist cloth. We do not advise using solvents,
white spirit or thinners as they could damage
the surface finish.
