What does the internal blue switch do on my MS and MPS series amps??
Early MS275s (as well as other early MS series amplifiers) had another two-position switch on the circuit board with a blue dot next to it. This is the Master/Slave switch. The standard position is towards the blue dot, which is the slave position. There are two 1/8″ mono phono jacks for connecting amplifiers together located on the amplifier’s end panel. The Master/Slave switch configures the amp as either the master or slave in a multiple amp installation. One amplifier is designated as the master amp with all others as slaves. This allows the master amplifier to control power supply switching for all amps. By switching all power supplies in sync, AM radio performance is improved by eliminating heterodyne noise. However, if connected and configured incorrectly, power supply damage to all amplifier power supplies is highly probable. For this reason, we eliminated this feature on later model MS amplifiers. The switch can be in either position and has no effect on performance if this fe
