Speck Electronics MicPre 5.0 - Manual (Page 12)

To avoid electrical shock, plug the MP 5.0 into a properly wired
receptacle. The ground pin of the power cord is internally
connected to the chassis. For safety reasons, do not lift the
ground on the power plug by using a ground lift adapter.
The location of the MP 5.0 should be such that the operator has a
clear, unobstructed view of the front panel from his/her normal
operating position. The unit should also be within easy reach of
the operators normal position in order to facilitate the use of the
front panel controls
The ½ rack form factor of the MP 5.0 allows a single unit to be
mounted on a table top with the (4) rubber bumpers supplied with
the unit, multiple units stacked, or two units mounted side-by-side
on a 1U rack shelf manufactured by Middle Atlantic Products
(Model UTR1).
When attaching the MP 5.0 to the rack shelf, it should be secured
with the (2) 6-32 x ½” machine screws supplied with the unit. Do
not use screws that are longer than ½” in length as they could
damage the internal circuit board. When the MP 5.0 or multiple
MP 5.0’s are mounted to the rack shelf, they may be installed into
any 19" wide equipment rack that uses standard E.I.A. universal
spacing.
Any device that emits a high EMI (Electro Magnetic Interference)
or RFI (Radio Frequency Interference) energy field should be
treated with suspicion. EMI is considered any unwanted signal
which adversely affects the operation of the MP 5.0 or the audio
system. This subject is discussed in Chapter 4.
Electronic equipment such as power amplifiers, power supplies,
video monitors, computers, certain synths and samplers must be
located away from the MP 5.0 and its associated audio cables. It
may be necessary to alter the positions of certain equipment that
you feel would cause buzzes or hums in the audio system.
