INSTALLATION AND OPERATION
PLACEMENT AND VENTILATION
Your Plinius SB-301 is designed to operate at a moderately high temperature, even more so when used in
Class A. The ideal location is on a rigid stand or floor mounted away from direct contact with any
temperature sensitive materials or deep pile carpets. The flow of air around the amplifier should also be
kept unimpeded, so ensure that the heat sinks (cooling fins) are not covered or restricted in any way to
ensure adequate ventilation.
The Plinius SB-301 design incorporates a very high level of mechanical decoupling of the input and
output. It can however still be influenced by acoustical feedback in the operating environment. The use of
acoustic cones or a suitably spiked amplifier stand or table may further enhance the performance of this
amplifier. Consult your PLINIUS dealer for further advice if required.
MAINS VOLTAGE CONNECTION
Firstly check that the mains supply voltage printed on the rear of this amplifier is similar to the mains
supply voltage in your area. If in doubt, please consult your PLINIUS dealer.
Mains supply power connection is via the supplied plug-in lead. A standard IEC socket connects the
mains power at the amplifier end while a local mains plug is required at the wall end.
The wiring code used inside all Plinius product is:
Green to Earth/Ground
Blue to Neutral
Brown to Phase/Live
Should a ‘local’ plug need fitting to the wall end of the lead, ensure that a suitably qualified or experienced
service technician wires the plug correctly.
IMPORTANT: DO NOT POWER UP YOUR AMPLIFIER UNTIL YOU HAVE CONNECTED
YOUR INPUT/OUTPUTS CORRECTLY FOR YOUR SYSTEM, (AS
EXPLAINED IN THE NEXT SECTION).
