to the bhi power supply (optional extra) or any suitable 12
–24V dc power source (min 500mA), with a suitable 2.1mm
power connector, centre pin positive (fused at 3A).
3. 2 metre audio input lead terminated with a 3.5mm mono
jack plug. This lead connects to the external speaker
socket or earphone socket of your equipment.
4. Sensitivity control . This controls the input level to the
electronics of the NES10-2, and is adjusted depending on

is not being overdriven.
