Speck Electronics MicPre 5.0 - Manual (Page 32)

The following information is not specific to the operation of the
MicPre 5.0, but rather general information regarding the “care and
feeding” of an audio system.
A general discussion about AC, AC grounding, audio grounding,
EMI, and quality wiring is discussed in this section. These
subjects are very often overlooked or misunderstood, and should
be given consideration when interfacing your equipment to any
audio product.
A “quality” installation is essential when wiring any audio system.
When the time comes to actually interconnect your equipment,
proceed slowly. Interfacing the many pieces of electronic
equipment to your MP 5.0 and audio system should be a logical,
methodical process.
Start by connecting only your headphones or monitor power amp
to the mixer, and then add one line signal to the mixer at a time;
carefully listening and monitoring your progress. If a problem
arises, such as a buzz, hum, intermittent signal, or nonexistent
signal, stop at that point and solve the problem before proceeding.
Due to the high performance of the MP 5.0, it is recommended that
you use only the highest quality audio cable. A high quality cable
by definition, is a cable that provides good mechanical strength,
high microphonic noise immunity, high frequency response, low
crosstalk and 100% shielding ability. All audio cable used with the
MP 5.0 should be a 3 conductor foil shield type (2 inner conductors
and a shield drain conductor). It is not recommended that the 2
conductor "off the shelf cables" be used.
All wire and cable interfaced to the MP 5.0 should be terminated
with high quality connectors. A 1/4" plug or XL connector should
make a positive connection to its respective mating jack and
provide adequate strain relief to its cable. All connectors should
also have a metal shell to provide 100% shield for exposed
conductors.
Feel free to check with Speck Electronics for recommendation
when selecting cable and connectors.
