Krell Industries EVOLUTION TWO MONAURAL PREAMPLIFIER - Manual (Page 53)

Questions and Answers
Q. Why does the second preamplifier channel not respond when I select an input
or adjust the volume on the other preamplifier channel?
A. The two preamplifier channels must be linked together using the RJ-45 cable
in order for functions to be sent between preamplifier channels.
Q. I renamed the B-1 input on one of the preamplifier channels. Why does it still
read B-1 on the other preamplifier channel?
A. When two or more preamplifier channels are linked, basic functions such as
volume and input selection are simultaneously executed by all linked preampli-
fier channels. In order for linked preamplifier channels to recognize customized
menu functions such as renaming inputs, the clone procedure must be per-
formed. For more information, see Clone, on page 35, and Software Clone,
on page 45.
Q. When I adjust the balance, the sound moves to the side that is opposite my
adjustment. What is wrong?
A. The Evolution Two preamplifier is preset from the factory as either a left or a
right preamplifier. Make sure the preamplifier chassis with the white connectors
is used for the left channel and the preamplifier chassis with red connectors is
used for the right channel.
Q. What should I do if I see a DC ERROR message?
A. The Evolution Two preamplifier has a sophisticated DC protection system that
detects potentially harmful DC. Please contact Krell to determine what action
to take, if you see a DC error message.
Q. The Evolution Two preamplifiers are plugged into AC outlets and the link
cables are connected, but the preamplifier channels do not power on. What
should I do?
A. The link cables only pass data between preamplifier channels. The power sup-
ply chassis must be connected to the preamplifier chassis with the provided
12-pin DC cable.
