DAB500
Digital Radio Tuner
Owner’s Manual
INTRODUCTION
Congratulations on purchasing this Digital Radio Tuner from Cambridge
Audio. It is the result of an extensive Research and Development program
undertaken to identify the circuitry and components fundamental to our
highly regarded and critically acclaimed products.
This new DAB radio is an advanced digital product capable of receiving and
decoding the abundance of digital radio broadcasts available.
This unit takes advantage of the very latest, third-generation DAB chipset:
the highly integrated Frontier Silicon FS2020 module, which embraces the
FS1010 single-chip DAB/Audio processor. The unit is based on the META
processor design and Ensigma DAB IP licensed from Imagination
Technologies.
This is coupled to a high performance 24-bit/192kHz, WM8716 digital to
analogue converter, with built-in 128fs oversampling, from respected
manufacturer Wolfson Microelectronics.
Our aim in realising the DAB500 was to bring into the home digital radio's
beautifully clear reception, remarkable ease-of-use and superior text
information.
Interconnects are something that shouldn't be overlooked. Please do not
compromise your system's performance by using poor quality cables. A
system is only as strong as its weakest link. Your dealer can supply quality
Cambridge Audio cables, either digital or analogue, that will ensure the
DAB500 performs to its full potential.
Please do read and retain this guide as it contains important safety and
operational information.
Now we invite you to sit back, relax and enjoy!

SAFETY PRECAUTIONS
For your own safety please read the following instructions carefully before
attempting to connect this unit to the mains.
• Check that the rear of your unit indicates the correct supply voltage.
• If your mains supply voltage is different, consult your dealer.
This unit is designed to operate only on the supply voltage and type that is
indicated on the rear panel of the unit. Connecting to other power sources
may damage the unit.
This equipment must be switched off when not in use and must not be used
unless correctly earthed. To reduce the risk of electric shock, do not remove
the unit’s cover (or back). There are no user serviceable parts inside. Refer
servicing to qualified service personnel. If the power cord is fitted with a
moulded mains plug the unit must not be used if the plastic fuse carrier is
not in place. Should you lose the fuse carrier the correct part must be
reordered from your Cambridge Audio dealer.
The lightning flash with the arrowhead symbol within an
equilateral triangle is intended to alert the user to the presence
of uninsulated ‘dangerous voltage’ within the product’s
enclosure that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended
to alert the user to the presence of important operating and
maintenance instructions in the service literature relevant to
this appliance.
This product complies with European Low Voltage
(73/23/EEC) and Electromagnetic Compatibility
(89/336/EEC) Directives when used according to this
instruction manual. For continued compliance only
Cambridge Audio accessories should be used with this
product and servicing must be referred to qualified service
personnel.
PLUG FITTING INSTRUCTIONS (UK ONLY)
The cord supplied with this appliance is factory fitted with a 13A mains plug
fitted with a 3A fuse inside. If it is necessary to change the fuse, it is
important that a 3A one is used. If the plug needs to be changed because
it is not suitable for your socket, or becomes damaged, it should be cut off
and an appropriate plug fitted following the wiring instructions below. The
plug must then be disposed of safely, as insertion into a 13A socket is likely
to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains
plug to the power cord the wires should be fitted as shown in this diagram.
The colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your
plug. Connect them as follows:-
• The wire which is coloured BLUE must
be connected to the terminal which is
marked with the letter ‘N’ or coloured
BLACK.
• 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
GREEN/YELLOW must be connected to
the terminal which is marked with the
letter ‘E’ or coloured GREEN.
NOTE:
If your model does not have an earth wire, then disregard this
instruction.
If a 13 Amp (BS 1363) plug is used, a 3 Amp fuse must be fitted, or if any
other type of plug is used a 3 Amp or 5 Amp fuse must be fitted, either in
the plug or adaptor, or on the distribution board.
