MSB Technology Link DAC III User Manual page 4

Power Supply Upgrades
The performance of the LINK can be improved with a larger power sup-
ply. The MSB P1000 is designed as an add-on to the LINK III.
Configuration Options
Inside the LINK III are several headers with jumpers installed. They
change various functions of the LINK III and allow upgrades to be in-
stalled. Several options can be set by the user including phase invert,
digital zero switching and a modification to the analog filter.
Opening the LINK III
Place the LINK III on a soft surface like a tablecloth or carpet. Discon-
nect the power supply. Remove the three philips screws on the back
edge of the cover. Turn the LINK over and remove the three philips
screws from the front edge of the cover. Carefully separate the base from
the cover. Pick up the base and flip it over, placing it inside the cover.
Take care not to disconnect the ribbon cable to the front panel. Place the
LINK so that the RCA connectors are facing AWAY from you. This way
all the diagrams will be oriented correctly.
Phase Invert
Phase invert is normally switchable with the toggle switch on the rear
panel. Phase invert can be permanently set inside the LINK III instead.
Locate the header labeled J14. Remove the switch and place a jumper as
shown.

Digital Zero Option
The analog bypass is normally interrupted when a digital input is active.
Active means that the source plugged in is turned on, not necessarily play-
ing, but just powered on. This feature can be changed to only switch when
nonzero digital audio signals are present. It will ignore data such as
Dolby Digital and DTS signals. In this case the analog input is only inter-
rupted when the digital source is playing valid audio, not just turned on.
Remove the first jumper on J 14 labeled "Zero Option". The jumper may
be placed on just one pin for future use.
