PLINIUS SB-301 MKII
Product Features
ERROR DETECTION
The Plinius SB-301 MKII Power Amplifier has in-built error detection. This will function
under the following conditions:
•
When the amplifier is overdriven/clipped
•
If any internal fuse is damaged.
Should either of these circumstances arise the amplifier will disconnect both
channels and mute the input. This condition will remain until the input signal level is
reduced or the damaged fuse replaced. When error detection is triggered the power
LED will turn off and the mute LED will pulse. The internal error LED (located towards
the front of the circuit board in the top cavity of the amplifier) will also light.
FUSE PROTECTION
When any internal fuse is damaged one or more fuse warning LEDs will light. These
LEDs are under the amplifier lid located near the centre of the main circuit board
with the rail fuse holders. If any of the internal fuse LEDs are glowing ensure that
your amplifier is switched OFF and disconnected from the mains supply. The lid of
the amplifier will need to be removed and the fuse adjacent to the lit LED should be
replaced. Replace them with the same type only.
IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING.
NOTE: that fuse failure may indicate a severe problem. Check all speakers and
speaker cables for damage etc. Should the amplifier continue to exhibit rail fuse
failure, contact your Plinius dealer.
MAINS/LINE FUSE
A Mains/Line fuse is fitted within the IEC Mains/Line socket on the rear of the amplifier.
A small drawer at the bottom of this socket may be removed (after the IEC plug is
removed) by levering it out with a flat blade screwdriver. The fuse fitted should be
rated as specified on the rear panel.
In the unusual event that this fuse should blow, you must first establish the cause of
this failure (such as power surges, damaged mains cable etc) before replacing the
fuse with one of the same rating and type.
IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING.
NOTE: Fuse failure may indicate a severe problem. Should the amplifier continue to
exhibit mains fuse failure contact your Plinius dealer.
