2.5 Power supply (15)
The PROLOOP DCCplus induction loop amplifier can be used in countries with 115 V or 230 V mains power
supply.
1. Set the voltage selector (14) to the correct position.
Position "115" for countries with 100 to 120 V (AC) or Position "230" for countries with 220 to 240 V (AC).
Note
The voltage selector is set on "230" position when the PROLOOP DCCplus induction loop amplifier is
delivered.
2. Please check if the fuse holder contains the correct fuse.
3 A fuse (T) if the voltage selector is set on "115" or
1.5 A fuse (T) if the voltage selector is set on "230".
Note
A 1.5 A fuse (T) is set into the fuse holder when the PROLOOP DCCplus induction loop amplifier is
