OPTIONAL DC POWER CONNECTIONS
If you have opted for one of our external Whirlwind
DC power supplies this should be connected using
only the cables supplied with the Whirlwind. We
strongly recommend that you do not replace or
attempt to modify these cables. Doing so can
adversely affect the CD player’s performance and is
likely to cause damage.
You will also need to re-configure your player for
external DC operation using the internal jumpers as
described below.

SWITCHING YOUR CD PLAYER ON AND OFF
If you are using a Whirlwind external DC supply to
power the analogue parts of your CD player we
suggest that this, once connected, is left switched
on all the time. To avoid “switch-on thumps” being
transmitted to your loudspeakers when you switch
on your CD player, we recommend that you always
switch on – or cancel mute on – your amplifier last.
Start by powering source components, such as your
CD player, then power the pre-amplifier. Then switch
on the power amplifier. When you’ve finished
listening, mute or turn off the power amplifier and
then mute your pre-amplifier. Finally, turn off your CD
player and other source components. You may, if
you wish, leave your CD player powered up at all
times: this will enable it to deliver optimum
performance as soon as you begin listening,
however we suggest that you switch off the display
when not required. This requires that a disc is
present in the player at all times.
The power switch mounted on the Thunder’s rear
connects and disconnects the mains supply. When
mains is connected, the display on the facia will
illuminate. If you plan to be away from home for long
periods – when, for example, you are on holiday –
you can use this switch to power down the CD
player completely. For absolute safety, disconnect
the mains lead from the wall socket. We advise that
you do this during thunderstorms to avoid damage
from power line surges.
REAR PANEL
MAINS CONNECTIONS
Next to the mains switch, on the rear panel, is an
IEC socket into which the supplied mains lead fits.
The fuse in the UK mains plug is a 3A standard type.
Again, if you need to replace it use an identical type
rated at 3A. If the fuses keep blowing return the CD
player to your dealer.
OUTPUT CONNECTIONS
The analogue output sockets on the CD player are
found on the rear panel. Connect these to your
amplifier or pre-amplifier’s CD input using high quality
interconnect cables (we strongly recommend Merlin
cables for optimum performance). On all players, the
socket marked in red is the right channel, and the
white socket is the left channel.
There are digital outputs as standard on all our
players. Our research shows that the levels of signal
jitter caused by separating the player’s transport
mechanism and DAC introduce an unacceptable
degradation in sound quality, counteracting the
benefits accrued through using our high quality,
ultra-low jitter, 24-bit DAC. If you wish to make digital
recordings you will need to switch on the digital
output provided using the yellow internal jumper, see
Before attempting to re-configure your player,
disconnect the mains lead at the wall socket.
Having made your player safe, remove the cover
by unscrewing the five screws located on the rear
and the four on the underside. The cover slides off
backwards. Locate the blue jumpers using the
diagram above (Diagram 1.) and position them for
the desired configuration. Replace the cover,
connect your Whirlwind power supply and re-
connect the mains lead to the wall socket.
