8.3 Shields & Grounds of Equipment
The shield of any audio cable connection should be connected at one end only.
If not, ground loops and high frequency cross-talk could result.
Connect the shield as a general rule to the signal source (output) of anything. In
high RF areas it is wise to connect the other end of the shield through a 0.01
microFarad capacitor. This will ground the RF but will not affect audio
frequencies.
When connecting balanced microphones
, use two conductor shielded audio
cable and connect both conductors and the shield at both ends.
When connecting line level cables, use two conductor shielded cable and follow
the instructions in the paragraph above. Remember, the shield is not considered
to be "ground" and it should only be connected at the output of any device.
There are only a couple of exceptions to this rule, one is patch cords and the
other is microphone cables. We realize that the correct interfacing of different
equipment is difficult, but once properly installed, the system will be clean and
noise free.
It is important to understand the term balanced. Balanced does not mean the
input or output is professional, the single factor that normally determines
whether something is professional is the level of the input or the output. +4 dBu
is considered professional. -10 dBv is considered to be consumer level
semi-professional. Because many semi-professional tape machines are built to
professional specifications, D&R builds into the Cinemix console the ability to
interface with both levels.
Note: When checking your new Cinemix console for noise, you will notice that
the console is extremely quiet without any external equipment hooked up. D&R
is not responsible for the noise you will experience when interfacing other
equipment. Since you are use to other consoles when first encountering a D&R,
the lack of noise from your Cinemix makes you more aware of noise from other
equipment as you hook it up. D&R recommends using the highest quality
external equipment with the Cinemix. Because high quality sound must be
monitored with speakers and amps with extreme specs, D&R suggests using
only the best amps to drive your speakers.
