Internal Fuses And Configuration - IC Audio AMP 120 Bedienungsanleitung

9. Internal fuses and configuration

9.1 Internal extra-low voltage fuse
If there seems to be no supply voltage in a device, the rear side mains fuse and the internal extra-
low voltage fuse have to be checked first – see photos below. Of course only fuses with identical
value may be used.
The internal extra-low voltage fuses have the following specifications:
AMP 120 15 A, 6.3x32 mm
AMP 240 20 A, 6.3x32 mm
AMP 480 40 A, 10 x 38 mm

All amplifiers AMP-series can be set up for 3 different values of input sensitivity by jumper SW401:
100 mV, 500 mV and 1 V.
Factory setting is 500 mV.
