of the PC Board. They are placed right next to the Crystal unit, and are 
connected to this. NB! There is also another light grey smd capacitor near by, 
it is not connected to the crystal unit. Do NOT remove this component!
SMD 
components are Removed by alteringly each solder terminal, in a rapid pace, so 
the component finally melts off. Never use force on such components, the PC 
Board can be damaged. 
LClock Gnd (Blue twisted wire) is Connected to jumper 
pos. nr. 9091.
LClock Out (Red twisted wire) is Connected to the Crystal unit 
PCB solder pad closest to the front panel. +12 V (Red single wire) is taken from 
78M15 pos. 6577, right hand PCB solder pad, (output) when you see the text 
'78M15' correctly. 78M15 is placed near the right hand corner of CD transport, 
on the main PC Board.

Remove the top plate, You need a Torx 10 screwdriver for this 
job. Remove the original crystal unit, it is placed right in front of the 'Coax 
Out' plug. 

Remove the green choke (looks like a resistor, but green) right 
next to the crystal unit. Also remove the yellow capacitor next to the crystal 
unit. 

Cut pin 10 of the nearest 74HCU04.

Since there is no designators on MicroMega's Circuit Board, we 
have to use photos instead
 



 


 

 


This installation shows a LClock C2, but the XO clock 
fits in the same manner, just using connection wires instead.
Short Circuit 
the two solderpads from the now removed crystal unit.
Connect LClock Out (Red 
twisted wire) to pin 9 of the 74HCU04.
Connect LClock Gnd (Blue twisted wire) 
to pin 7 of the 74HCU04.
Connect LClock +12 (single red wire) to the input of 
the 7805 showed. This is the left pin when reading the '7805' text 
correctly.

Remove the topcover on the 
CD player enclosure. The Crystal unit is a bit hard to locate, but it IS 
there!
It is placed on the large PCB assembly in the middle of the CD player, 
right next to the PCB wire connector with the two grey wires. It is a tiny 
cylindric Crystal unit measuring just 2,5 m.m. in diameter and 10 m.m. 
length.
On the Crystal unit (pos. X101) is marked 4YBH, a rather 
noninformative text but it IS a 16,9344 MHz crystal.
Remove X101, C157 and 
C158. It is accomplished by removing the three wire connectors from the PC 
Boards right hand edge ( when you view the CD player from the front panel ), 
loosen screws holding the PC Board, and the nut on the Coax Out jack from the 
exterior. Tilt The PC Board gently out of the chassis.
Connect LClock Out 
(Red twisted wire) to the PCB solder pad of X101 furthes away from the CD 
transport.
Connect LClock Gnd (Blue twisted wire) to the PCB solder pad of 
C157, closest to the rear panel.

Remove the top cover, 
for this you need a 2 m.m. hex-key and a pozidrive screwdriver. 
Numeral is 
not equipped with a Crystal unit, but instead it has a (cheap) clock generator, 
it is placed at the midst of the PCB assembly, which also holds the XLR and RCA 
jacks. It is a blank shiny square metal can of 10 by 10 m.m.
There is also a 
clock generator on the CD transport PCB, it is purposed to run when the 
transport is used with another DAC the the Numeral. Don't bother tampering with 
this other clock generator. 
Remove the clock on the XLR/RCA PC Board, it has 
pos. X1. It is done by adding lots of solder to all four PCB solder pads, and 
heat them two and two changing in a rapid pace. At the same time, carefully pull 
the can out of the PCB in tiny steps with a finger.
Connect LClock Out (Red 
twisted wire) to the PCB solder pad of X1, furthest away from the sharp corner 
of the clock generator symb? on the PCB.
Connect LClock Gnd (Blue twisted 
wire) to den PCB solder pad of X1, closest to the sharp corner.
Connect 
LClock +12V (Red single wire) to right hand PCB solder pad (output) on U5 (7812) 
it is placed approximately 4 cm. towards the frontpanel starting from 
X1.
