Power Supply - MSB Technology Select DAC II User Manual

Power Supply

The Select DAC has a complex power structure.
The DAC has two connectors on the back. Both
require power for the DAC to operate. One side
is Analog and the other side is digital. The better
isolated these two supplies are the better the DAC
will preform. The standard SELECT power
base is a dual supply, with separate transformers
for each side. An system upgrade is to use two
separate mono power supplies, one for each side.
Input Power
Plug the power base directly into the wall power.
In most cases that will sound best. The SELECT
power base contains an isolation technology
and the same kind of noise shield as the MSB
Isolation base. The Power Base detects the
input voltage and switches for 120 V or 240 V
operation.
Note that a special Power Base is made for 100V
which will switch between 100V and 200V. All
supplies are protected from over voltage.
Two fuses are provided:
* 5A 250V SLO BLO - 5 mm x 20 mm miniature fuse is the main fuse.
* 100mA 250V SLO BLO - 5 mm x 20 mm miniature fuse is for the standby supply only (not used
for the DAC).
These fuses are to protect the product in the case of internal failure. These fuses should not blow
during unusual power surges or disturbances. To check the fuses, remove the cover and examine.

Power Supply LED Color Table
White: The unit is on and operating
Pink: The button for the unit is on, but the 12V trigger has
turned it off, OR, the button for the unit is on, but the
protection has shut if off because of overheating or
over voltage.

Power Indicator
The button on the front of the unit turns the
output power on and off. The switch will
show white when powered on, and red when
off, indicating that the unit is plugged into
power. If the remote trigger is used to turn
on or off the unit, the color when off will
be pink to indicate it is being controlled by
another source.
Power Indicator Brightness
The DAC display brightness is set using a
menu feature, but brightness of the power
supply indicator is set using a small dimmer
knob on the bottom of the unit, just under
the power button. You can reach under the
front of the unit and feel the dimmer wheel
and adjust the brightness if you like.
Under the front edge of the Power
Base is a Power Indicator Brightness
adjustment and a switch to select the
number of Power Bases you have:
NORMAL for 1
LINKED for 2.
