Buzz on my speakers: What am i doing wrong?
I have the Tapco S8 speakers and a juli@ soundcard which has changeable I/O part. one is cinch (rca) and the other is 6,3. the speakers have rca/6,3 and xlr inputs. when i use the rca on both soundcard and speakers there's no buzz. when using the 6,3 connected to the speakers there's buzz.- tried two differnt styles of 6,3 plugs - instrument cables (mono) and others (stereo). if i am correct. only ones that give no buzzing are rcas??
list from the manual of the tapco s8s:
RCA Plugs and Jacks
RCA-type plugs (also known as phono plugs)
and jacks are often used in home stereo and video
equipment and in many other applications. They are
unbalanced and electrically equivalent to a 1/4" TS
phone plug.
1/4" TS Phone Plugs and Jacks
“TS” stands for Tip-Sleeve, the two connections
available on a mono 1/4" phone jack or plug. They
are used for unbalanced signals.
1/4" TRS Phone Plugs and Jacks
“TRS” stands for Tip-Ring-Sleeve, the three
connections available on a stereo 1/4" or balanced
phone jack or plug. TRS jacks and plugs are used to
make balanced connections to the S•8:

from the description of the soundcard:
Specifications.
- 2 analog inputs and 2 analog outputs with unique swappable I/O socket design: users can choose between unbalanced RCA I/O (-10dBV) and Balanced TRS I/O (+4dBu)
from the manual of the tapco s8s i get the impression that the inputs are ment to be used with unbalanced trs (6,3) the soundcard has a balanced output. could this be the problem?
from the speaker manual:
• Unbalanced TS (Tip-Sleeve) lines can be
accommodated via the TRS jack. See “Appendix B:
Connections” for more information.
• When using a TS or TRS plug, make sure it is pushed all
the way into the jack. Partially inserting the plug into
the jack could result in a drop in signal level (by 6 dB).
