If no power comes out of the UPC-200 it probably indicates no power is going into the UPC-200.
There are no internal fuses. Check the front panel of the UPC-200 to see if the power light is lit. If it is
not, and no power is coming from the outlets of the UPC-200, there are several possibilities:
You are not giving the UPC power
Plug your AV unit into the same power source as the UPC-200 to test.
Another possibility is the line cord. Swap line cords and make sure the unit has power.
Sometimes the line cord feeding the UPC-200 is not functioning properly. Test both cords if
necessary.
If the UPC-200 and its powered equipment lose power mysteriously chances are pretty
good that you have the UPC-200 connected to a switched receptacle on the wall or the back of a
receiver or a power conditioner. Switched AC receptacles are those receptacles that are controlled
by a wall mounted power switch and are typically intended to be used to power on/off a lamp in the
room. Most times these receptacles are unmarked and inadvertent switching on or off of the power
switch can cause a lot of headaches trying to track down the reason your new equipment does not
power up. Most switched receptacles are on the top AC receptacle in a two gang box. Always use
the lower receptacle on the wall port if you are unsure.
The internal surge protector board has died
If there is a surge too large for the UPC-200’s internal surge protector to handle, the UPC-200 will
disconnect your equipment from the AC line. Therefore, no power will be delivered through the UPC-
200 rear mounted outlets.
If you have determined the UPC-200 does not pass power, after performing the above tests, turn to
the service section of this manual for details on receiving service.
If you do not hear or see a signifi cant improvement in your system’s performance, there are several
possibilities:
You have not upgraded the power cables
Whenever you place any piece of equipment in line with the AC power you add another power cable.
So, even if the new unit did nothing to improve the AC power, the mere act of adding two power cables
in series with each other can have a deleterious effect on performance. It is, therefore, critical that the
two power cords be of a higher quality and larger gauge then the original if possible.
Use shorter power cables of high quality so that the total length of the two power cables equals the
original length of the one power cable. i.e. two 1 meter cables with the UPC 200 between them,
relative to a single 2 meter cable plugged directly into the wall.
Use heavier gauge power cables
A typical power cable is 14 gauge and can constrict or limit the power delivery to and from the UPC-
200. The heavier the wire gauge of the power cables connecting the UPC-200 to the wall, the better.
The same rule applies to the output of the UPC-200, heavier gauge power cables are better.
