NOTE: These instructions apply in the United  
Kingdom only – consult your dealer about wiring  
conventions in other countries.  
The power switch mounted on the Thunders 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.  
Green and yellow wire connects to EARTH (E or  
symbol  
)
Blue wire connects to NEUTRAL (N)  
Brown wire connects to LIVE (L)  
Please ensure that the replacement lead contains a  
5A fuse.  
OPTIONAL DC POWER CONNECTIONS  
REAR PANEL  
Refer to Diagram on Page 11  
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.  
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 5A standard type.  
Again, if you need to replace it use an identical type  
rated at 5A. If the fuses keep blowing return the CD  
player to your dealer.  
You will also need to re-configure your player for  
external DC operation using the internal jumpers as  
described below.  
OUTPUT CONNECTIONS  
Before attempting to re-configure your player, dis-  
connect the mains lead at the wall socket. Having  
made your player safe, remove the cover by un-  
screwing the screws located on the top and those  
on the underside using a combination of a T10  
security torx driver and a No.1 posi-drive screwdriver  
lift the cover and locate the blue jumpers in the back  
right corner using Diagram 3 (see page 9) 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.  
The analogue output sockets on the CD player are  
found on the rear panel. There are both balanced  
and unbalanced connections available and we  
strongly advise you to use the balanced where  
possible. Connect these to your amplifier or pre-  
amplifiers CD or Auxiliary 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 both optical and coaxial digital outputs as  
standard on all our players. Our research shows that  
the levels of signal jitter caused by separating the  
players 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 Diagram 1 (see page 7).  
However, we caution you that this addition will have  
a slight detrimental effect upon the players  
performance.  
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  
Before attempting to re-configure your player, dis-  
connect the mains lead at the wall socket. Having  
made your player safe, remove the cover by un-  
screwing the screws located on the top and those  
on the underside using a combination of a T10  
security torx driver and a No.1 posi-drive screwdriver

configuration. Replace the cover and re-connect the

should now work accordingly.  
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.

VARIABLE OUTPUT VERSION.  
TIME: Push once during Play mode to display the  
time remaining on the current track. Push again to  
display the time remaining on the disc. Push while  
the player is in Stop mode to display the total  
number of tracks and playing time of the disc.  
Note: if the disc contains more than 69 tracks the  
display will show “_ _ . _ _” instead of the remaining  
time. It will show the same if the remaining time  
exceeds 100 minutes during PROGRAM PLAY  
mode.  
If your player was specified as a variable type then  
you will find a label “VAR”‚ next to the serial no.  
There is no readout or display of the volume however  
it will remember where you last left it, even if you  
power the player off. So in answer to the question;  
How do I know how loud it is? It is where you last left  
it! The mute function on the handset will also mute  
the players output completely, push the button for a  
second time and output will be restored. There is  
enough gain to drive any power amplifier into clip-  
ping however the factory default setting is quite low,  
as we do not know what amp and speakers you  
may have and we do not want you to leap out of  
your skin when you first play a disk. The volume  
control operates in the analogue domain so you are  
not reducing the bit count or resolution, it is a micro  
processor controlled resistor ladder and has only a  
very subtle effect on sound quality like any volume  
control.  
DISPLAY: Push once to turn off the display. Push  
again to return the display to full brightness.  
Note: When the display is switched off, pushing any  
control on the player or remote handset, or changing  
the disc, will switch on the display for about 3  
seconds. Please note that this function only works if  
a disc is present in the player and playing.  
REMOTE CONTROL FUNCTIONS  
As well as duplicating the major controls found on  
the player, the remote handset provides the following  
additional features.  
OPERATING YOUR CD PLAYER  
You can control the major functions of your CD  
player from either the remote control handset or the  
buttons on the player’s facia. If you simply wish to  
play a disc you do not need the remote control.  
However, do not lose the handset because it is  
required when you wish to program the player or use  
features such as FF or FR.  
PROGRAM: push to construct a program  
containing up to twenty-four selected tracks. The  
player will play your selections in the order in which  
you enter them into the program.  
1. Select a track number by pressing the PREVIOUS  
or NEXT key, or by using the numerical keys.  
2. Press PROGRAM. “PROGRAM” appears on the  
display panel indicating Program Play mode. This  
is quite dull.  
PLAYER CONTROLS  
OPEN: Push once to close the player’s drawer after  
inserting a disc. Do not push the drawer closed with  
your hand as this can damage the drawer  
mechanism.  
3. To add further tracks repeat steps 1 and 2.  
Once you have entered all the desired tracks, you  
can play your programme by pressing the PLAY  
button  
PLAY/PAUSE: Push once to start the disc playing. If  
the players drawer is open, pushing play will cause it  
to close and commence playing automatically.  
Pressing for a second time whilst playing a disc will  
pause the disc.  
To erase a programmed track, press the CLEAR key.  
Each time you press CLEAR, the last selection in the  
program will be removed. Press STOP to stop the  
program playing, then press STOP again.  
REPEAT: Push once to repeat the whole disc. Push  
twice to repeat the track currently playing. Pressing  
the button a third time returns normal operation.  
FAST FORWARD and REWIND: To move rapidly to  
a particular section of music you can use the FAST  
FORWARD or REWIND keys, depending, obviously,  
upon whether you wish to access a section not yet  
reached or one that you have passed. While the  
player is in Play mode you will hear music playing at  
high speed. To move quickly through the disc in  
silence, press PAUSE before pushing the FF or REW  
buttons.  
STOP: Push once to stop the player operating.  
PREVIOUS: Push during Play mode to play the  
previous track. Pushing more than once will cause  
the player to go back an equivalent number of  
tracks.  
NEXT: Push during Play mode to play the next track.  
Pushing more than once will cause the player to  
advance an equivalent number of tracks.  
NUMERIC KEYS: These are used for entering  
selections in Program mode or for starting Play  
mode from a particular track. For example, loading a  
disc and then pressing “7” will cause the player to  
start playing the disc beginning at track 7. To access  
tracks greater than 9, first press “0” followed by the  
track number required.

VOLUME: The volume buttons will operate the  
volume function on any remote control amplifier that  
accepts RC5 commands. They are provided solely  
for your convenience, as there are no volume control  
functions on the CD player  
TIMER MODE  
Your player is equipped with a Timer Mode. This  
allows the player to automatically play a disc when  
powered on from the mains via the use of an exter-  
nal timer. It is switched off by default at the factory.  
To turn this on follow the instructions below using  
Diagram 2 (see page 8).  
HIDDEN MODES  
These are only accessible with the use of an RC5  
handset with the appropriate keys (Not the supplied  
handset).  
Before attempting to re-configure your player, dis-  
connect the mains lead at the wall socket. Having  
made your player safe, remove the cover by un-  
screwing the screws located on the top and those  
on the underside using a combination of a T10  
security torx driver and a No.1 posi-drive screwdriver  
lift the cover and locate the yellow jumper located in  
the bottom right corner of the main PCB using  
Diagram 2 (page 8). To set the Timer ON remove the  
yellow jumper or place it in such a way that it is held  
by only one pin. Replace the cover and re-connect  
the mains lead to the wall socket. The Timer Mode  
should now be operational via the use of an external  
mains power timer.  
SHUFFLE: Press SHUFFLE followed by PLAY to  
listen to tracks in a random order. To cancel Shuffle  
mode, press SHUFFLE again.  
INTRO: Press INTRO and the player will scan  
through the disc playing the first 10 seconds of each  
track. Press INTRO while in Play mode and the  
player will scan through the disc playing the first 20  
seconds of each track. To cancel either Intro mode  
simply press PLAY.
