Surround Monitor Controller 2489
IMPORTANT: Before connecting the SMC or any other equipment turn off all
power at all units.
It makes good sense to think about where you place your SMC before connec-
ting it. It should be positioned so that you can easily reach it, but there are
other considerations. Try not to place it near heat sources or in direct sunlight,
and avoid exposure to excessive vibrations, dust, heat, cold or moisture. It
should also be kept away from transformers, motors, power amplifiers and
digital processors. In addition, please:
• Do not open the case. You may risk electric shock and damage to your
equipment.
• Leave repairs and maintenance to a qualified service technician. Should
foreign objects fall inside the case, contact your authorized dealer or
support person.
• To avoid electric shock or fire hazards, do not expose your unit to rain or
moisture.
• In case of lightning, unplug the unit. Always unplug the cable by pulling on
the plug only; never pull on the cable.
• Never force a switch or knob.
• Use a soft, lint-free cloth to clean the case. Avoid cleaning agents as they
may damage the unit.
The SMC’s power supply was carefully engineered to provide clean and consis-
tent current – an important prerequisite for excellent audio. Built around a
toroidal transformer, the power supply generates a minimal electromagnetic
field with no hum or mechanical noise. The output side is filtered by an RC
circuit to extract noise and hums inherent in commercial AC power.
All audio-related components are fed by two separate voltage regulators to
minimize disturbance from other components.
An AC power cord is included for connection to the standard 3-prong IEC
connector. The transformer, power cord and IEC connector are VDE, UL and
CSA approved. The AC fuse is rated at 315 mA (230 V version) or 630 mA (115 V
version).
