Installation
In your System
While the SP20 does not dissipate an unusual amount of heat, it is important
that it be provided with reasonable airow to assure long, trouble-free
operation. In addition, the following installation guidelines will help insure
maximum sonic performance as well as reliable service:
Operate unit in upright and horizontal position, preferably on solid, non-
metal shelving.
Do not stack the preamp on top of a power amplier: not only could this
cause overheating, but hum may be introduced into the preamp from the
proximity of the amplier’s power transformer.
Do not stack components or other objects directly on top of the SP20.
Do not place or operate your preamp on a soft or irregular surface such as
a rug. This will prevent proper ventilation.
Do not operate your preamp without the top and bottom covers installed.
These are required both for safety as well as shielding from interference
(except in service operations by qualied personnel).
Ensure a minimum of 8-10” clearance above the unit when placed on
shelving.
