Okay, so you have a flashing light. Deep
breath. We’ll get this taken care of shortly.
When the Vidar 2’s front light flashes during
operation (and the amp mutes), or if it never
stops flashing after you turn on the amp,
there’s a problem, or fault. There are three
kinds of faults:
1. Over-temperature. The heatsinks are too
hot, and Vidar has shut down to protect its
output. If the amp is very hot, turn it off, wait
a while for it to cool down, and try turning
it on again. Please note that in some very
hot ambient environments (over 80 degrees
F), you may need to use an external fan to
avoid over-temperature faults.
2. Over-current. If Vidar is connected to
very low-impedance speakers (2 ohms in
stereo, or 4 ohms in mono), playing very
loud music can cause an over-current condi-
tion. Simply turn the amp off and on again
to clear this fault.

Alternately, Vidar may shut off from over-
current if the speaker cables are shorted. To
troubleshoot this, turn off the amp, discon-
nect the speaker cables from the amp, and
turn it back on again. If it comes back on,
there may be a short in your speaker cables
(or your speakers). Examine your connec-
tions to ensure there are no stray wires or
shorts. Once those have been fixed, you
can reconnect the speakers and play music
again.
3. High DC offset. Vidar is a DC-coupled
amp. Its microprocessor monitors DC levels
at the output. However, it may not always
be able to correct for extremely high DC
from your source (such as a preamp). To
clear this fault, turn off the amp, disconnect
the RCA cables or XLR cable from the amp,
and turn it back on again. If the amp turns
on normally, then there may be high DC on
the output of your source. Have the source
inspected and repaired.
