Q. I own both a CD andDATplayer. Do I have to change my cables every
time I listen to a different digital source?
A. No. Your SBP-64X will accommodate both thefiber optic an~l coaxial input.
Simply connect both sources using the separate inputs.
Note; When the SBP-64X senses two live inputs simultaneously, it will default to
thefi~er optic link. Therefore, when you wish to listen to the source linked with
coa£ial cable, you must turn the other (optically linked) source off.
Q.
Will I damage my SBP-64X if I leave the power "ON" all the time?
A. No. These Class "A" analog circuits are most accurate and stable if left to idle
when not in use, and the circuitry ages fastest when cycling "ON" and "OFF".
The fact is, your Krell Digital processor will sound better and probably last longer
if left "ON".
Note: For the protection of your processor, we recommend disconnecting the
power supply from the wall oudet before any electrical storms or if you plan on
being away from your home for prolonged periods of time.
Q.
Do I have to switch the Sampling Frequency when I go between my CD
and DA/?
A.
No. Your SBP-64X automatically senses the input frequency and does all
necessary switching.
Q. Sometimes, while listening to myDAT, the 44.1 k//zLED is illuminated.
I thought DAT used 48 kHz. Is my processor malfunctioning?
A.
Some Digital Audio Tape recorders can record and playback in either 44.1 kHz
or 48 kHz depending on the source the tape was recorded from. The SBP-64X’s
LED’s are informing you of the frequency it is receiving, and as a consequence,
the sampling frequency at which the tape was recorded in.
Q. I’m not getting any sound through the processor.
A. Most likely, there has been a simple mistake in installation.
Suggestion: Check all connections IN and OUT from the processor. Check all
power connections. Make certain that the power supply is switched into the ON
or UP position. Have you selected the correct source on your preamp? Check
the front panel LED’s for power supply stability.
If you still have no sound, turn off the power and contact your dealer.
Q.
I have some very fine audiophile interconnect cable which has superior
sonic characteristics. Can I use this for my coaxial digital input?
A. You may experiment with any high quality cable. Do note, however, that most
audio interconnect cable is not designed to carry the ultra high frequency infor-
mation of a digital bit stream.
Note: For the SBP-64X, we recommend non-capacitive coaxial cable which has
a bandwidth in excess of 10 MHZ and excellent shielding properties.
Q. While listening to my SBP-64X I experience occasional periods of silence
through my speakers. Is my processor malfunctioning?
A. These drop outs are caused by bad data in the digital stream which is sensed
by the SBP-64X. This corruption in the data may be due to a poor input con-
nection, damaged or dirty source material, or interconnects which do not have
a wide enough bandwidth.
This intermittent muting is caused by the SBP-64X. It is sensing the bad data and
muting the signal to prevent possible damage to your associated components.
Suggestion: Try changing your source material, and check your connections.
If these are not the causes, speak with your dealer about obtaining different
cabling.If you are usingfiber optics and source material and connections are
not the problem, speak with your authorized dealer
Q.
I am getting hum in my system only when I have the SBP-64X turned
"ON". Is there something wrong with my processor?
A. You must have placed the power supply in close proximity to a hum sensitive
component, such as your preamp or phono turntable.
Suggestion: Relocate the power supply in accordance with the installation
guidelines.
