While this does reduce the level of EMI, it may also degrade the performance of the circuit. If high speed data needs to be carried, then any sharp edges will be removed by the filters, and in the worst case, the signal may be attenuated to such a degree that the system does not work.

 · A circuit board is a piece of insulation that is threaded with conductive wires and similar components. When a power supply introduces an electrical charge to the board, it is distributed along these wires to different components in a variety of ways. This lets the board control how these components are activated and charged during the use of an electrical device.

For amplifiers with a 0.775V position, this positions corresponds to a 0 dBu level. The 1.4V position corresponds to a +4 dBu level. The 26 dB position is a fixed gain position. The 26 dB position is also the lowest gain position, and will usually work well with output levels of +10 dBu (2.5Vrms and above).
