CONNECTIONS - Analogue
Two sets of analogue outputs are provided for connection to your amplifier. Be sure
to set the amplifier’s volume to off before making the connection.
The De-emphasis process is now carried automatically within the DAC itself. We
recommend that the connections for right and left should only be made to the
sockets on the rear panel marked DIRECT for BEST RESULTS.
De-emphasis means that the CD has been encoded with a treble increase which the
`De-emp` circuit in the converter will correct. The BEST connection for most CD`s,
for sound quality, should be via the Direct Out.
CONNECTION – MAINS : The DAC has an IEC mains inlet socket, use the supplied
mains cable to connect the unit to the local mains supply, the fuse is situated in the
inlet socket as well.
OPERATING THE DAC2.
Once all the connections are complete, turn on the CD transport. Next turn on the
DAC by using the rocker switch located on the back panel next to mains inlet socket.
Now turn on the amplifier. Red led on front panel confirms unit is on.
If all is in order, the system is now ready to play music, and at last the sound of your
compact discs will be tolerable!
The DAC2 will improve over time and start to sound really well balanced. This is
because of the “bedding in” time taken by new electrical components inside the unit.
Also, the DAC’s sound quality improves as the unit reaches its normal, stable
operating temperature.
Only a rear panel on/off switch is provided as the unit is designed for continuous
operation. The DAC need not be switched off each time after use. It is interesting to
note that continuous operation not only results in optimum sonic performance (since
the unit is maintaining a constant operating temperature) but also causes less
electrical stress and so extends component and valve life.
EXPERIMENTING WITH DIFFERENT VALVES.
As mentioned before the 6DJ8/ECC88 have a number of equivalents and were made
by a large number of manufacturers, they are now only made in Russia and
Yugoslavia.
Equivalents include,
7308, E88CC, 6922, E188CC, CV2493 (E88CC), CV5358 (ECC88), CV 4110 (very
low noise E188CC version), CV4108, CV4109, CV4111 (all E188CC).
These were made by Sylvania, PhilipsECG, Mullard, Philips (Holland), Siemens,
Telefunken and many others.
The best I have found are the Telefunken E88CC 01 gold pin, expensive, but worth
every penny.
