Manley LAB SERIES DELTA SIGMA DIGITAL TO ANALOGUE CONVERTER - Manual (Page 5)

CONNECTING YOUR CONVERTER
Setting up your converter is rather easy.
1. Connect all source components (turntable, CD, Tuner, Tape DAT, etc.) to
your preamplifier as normal, reserving one pair of inputs for the converter.
The usual choice is the CD inputs and not using the CDs internal (infernal)
converters and audio outputs.
2. Connect the RCA SPDIF interconnects from the output of the CD or DAT to
the RCA SPDIF input on the back of the converter . Use digital interconnects
for best performance. Video interconnects are a second choice but audio
interconnects will generally not be acceptable due to the fact that the digital
signal extends to several megahertz.
3. Ensure that the "mains" switch on the front panel is in the "off" or "0" posi-
tion and that the front panel gain controls are counterclockwise.
4. Connect the RCA audio interconnects from the left and right outputs of the
converter to the preamp inputs.
5. Turn on converter and CD or DAT you plan to use.
6. Verify that the LOCK LED lights at this time or when you start the CD or
DAT. If the LOCK LED is not lit turn the power switch off for 5 seconds
and turn it back on to reset the converter. If you ever have to do this make
sure the preamp is turned down to prevent potentially damaging thumps.
7. Wait 30 seconds to let the converter to warm up and reach stablity. Turn the
converter gain controls clockwise. On the preamp select the converter and
turn up the volume and enjoy.
8. The GAIN CONTROLS on the converter enable this unit to be optimized to
your system. You can use them to match the volumes with your turntable,
tuner and other inputs so that selecting the converter will not cause a drastic
change in volume. They also provide a way to interface direct to the power
amps if no other source is needed the power amp has no gain controls or the
controls are not practical to use. Of course, these are separate controls to
allow use as balance adjustments and maintain absolute minimum crosstalk.
The "purist" approach is to leave the gain controls fully clockwise so that the
pots are virtually bypassed.
