Okay, so you have a flashing light. Deep breath.
We’ll get this taken care of shortly.
When the Vidar’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.
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 condition. 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 trouble-
shoot this, turn off the amp, disconnect 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 connections 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
and adjusts it down to zero. However, it may not
be able to correct for 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.
