MK II

Use  high-quality,  shielded  cables  to  connect  your  console,  workstation  or 
other sources to your Blue Sky BMC MK II. Foil-shielded cables, such as Belden 
8451,  8761,  or  9501  should  do  quite  well.  Other  high  quality  cables  are 
available and those that incorporate better shielding will yield an overall higher 
noise rejection, lowering your systems susceptibility to external interference. 
Another important tip to keep in mind when wiring your system is to route all 
line level cables away from the AC and other power sources, this will reduce 
the probability of having AC hum emanating from your monitoring system.
