Speck Electronics LiLo - Manual (Page 14)

Chapter 2 Installation & Setup 10
In the unlikely event that a fuse blows, it is EXTREMELY important that a
fuse of the same type and current rating be replaced. The chart below in
Figure 7 lists the fuse current ratings to be used for your countries mains
voltage. All fuses are 20mm x 5mm slow blow type.
The LiLo will operate satisfactorily over a wide range of ambient
temperatures, and the external power supply will operate from -10º C to
+30 º C. If the power supply is installed in an equipment rack that also
contains heat producing equipment, adequate ventilation should be provided.
This will prolong component life and maximize operational stability.
While the internal circuitry of the Lilo is fully shielded by the chassis,
installation should nevertheless be planned to avoid locating the LiLo
immediately adjacent to power amplifiers, power supplies, or any source of
Electromagnetic emissions.
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 mixer or the mixing system. This subject is discussed in Chapter 4.
Electronic equipment such as power amplifiers, power supplies (especially
wall mount type), video monitors, computers, certain synths and samplers
must be located away from the LiLo and its associated cables. It may be
necessary to alter the positions of certain equipment that you feel would cause
buzzes or hums in the mixer system.
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 mixer and audio
system should be a logical, methodical process.
Start by connecting only the monitor power amp (or powered speakers) 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.
