My CD transport has both fiber optic and coaxial outputs. Which one
should I use?
Given a choice, we prefer the ST format due to its complete isolation of the
grounds between digital source and processor. This minimizes the
possibility of ground loops in the digital components. The ST format also
has the added benefit of substantially higher bandwidth than coaxial or the
standard fiber optic interface. If a coaxial cable must be used, we suggest
the AES/EBU balanced format. This format utilizes a -+ 5v digital format
and has the additional benefit of balanced termination.
Will I damage my KPS-20 if I leave the power ON all the time?
No it's intended to be on at all times. The circuits perform more consistently
once they reach thermal equilibrium.
NOTE: For the protection of your unit, we recommend disconnecting the AC
cord from the wall outlet before any electrical storms or if you plan on being
away from home for prolonged periods of time.
I have some very fine audiophile interconnect cable which has superior
sonic characteristics. Can I use this for my coaxial digital input?
You may experiment with any high quality cable. Note that most audio
interconnect cable is not designed to carry the ultra-high frequency
information of the digital bit stream.
NOTE: For the KPS-20, we recommend non-capaditive coaxial cable which has
a bandwidth in excess of I OMHz and excellent shielding properties. This is
true on both RCA and XLR terminated cables.
When I try to play a certain disc the KPS-20 displays an error message and
will not play. Is the transport defective?
Check to make sure the magnetic clamp is properly centered on the disc. If
this is not the problem, the disc may need to be cleaned. If the surface of
the disc is soiled the laser cannot read the data and ~will display an error
message or skip sections of tracks. You may want to experiment with some
of the compact disc cleaning products. If after cleaning the disc, it still will
not play, the problem may be with the indexing on the CD. Some recording
companies stretch the parameters of the CD, preventing them from
