Speck Electronics EQ16 - Manual (Page 31)

All wire and cable interfaced to the EQ16 and Speck products 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.
Speck Electronics offers a complete line of interface cables for the
project studio. Contact Speck or your dealer for information on these
cables.
When you are evaluating voltage and current requirements for your
audio system, it is important that your EQ16 equalizer and/or rack
system does not exceed the capacity of your AC service. You should
make certain that the earth (green) wire for the AC system makes a
reliable earth connection, and determine as best as possible that the AC
system is free of noise that could generate unwanted audible sounds or
cause problems in microprocessor based equipment.
When using a larger rack system it is recommended that a dedicated and
isolated AC service be provided. This service should have its own AC
wires, isolated receptacle, and breaker and not be shared with other
unrelated equipment.
Even with an isolated AC system, it may still be necessary to make use
of surge protectors, line filters, isolation transformers, or all of the
above.
Power conditioners should be selected with care, since they sometimes
generate undesirable switching noises in audio systems.
When connecting many pieces of electronic equipment to an AC system
it is important that the AC is properly distributed. It is better to connect
all plugs to a common AC source than to have AC receptacles in
different locations.
When installing a large audio system, it may be necessary to consult a
qualified electrician that is familiar with the specialized style of
electrical wiring required for recording studios.
