LED BRIGHTNESS CONTROL

Your Plinius SA-250 has an internal LED brightness control that will adjust all three front panel LED’s. A small flat bladed screwdriver can be used to adjust the brightness. The LED brightness control is a small multi turn potentiometer and is located on the front of the main circuit board within the top cavity of the amplifier, and is labelled VR5. Make sure you adjust the correct potentiometer, and remember to remove the mains supply from the amplifier before making any adjustments.

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 at no greater than 20 amps normal blow.

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.
