3. Voltage Selection PCB;
The Voltage Selection PCB is located in the front of the chassis by the power & standby switch & is
secured by 4 self tapping screws.
The fuse, NTC & link wires, on the PCB must be configured for the required voltage as set out in the table.
1. Power switch;
In general appearance the 2 switches look the same,
but use 007305 for 230V & 007435 for 100 -115V range.
Nexus Bass Amplifiers can be adapted to run from different
voltages by making changes in three places.
1. The Power Switch
2. Mains Inlet & Resettable Trip
3. The Voltage Selection PCB
2. Mains Inlet & Resettable Trip;
The mains inlet & resettable trips must be changed as set out in the table below for the
various voltages.
The items are located at the rear of the amplifier as in the photo.
The Mains Inlet is secured by 2 x M3 screws, nuts & washers, & the resettable trip is secured
by 1 x hex nut.
