Advanced Application - Remote Turn-on
If you wish to operate an amplifier channel in low power standby with remote turn-on, set its rear panel switch to SLAVE.
Ex5 volts connected to the FAULT FLAG holds the amplifier in standby.
Floating the FAULT FLAG or connecting it to ground turns the channel on.
Basic Application
Don't let those extra connections and switches intimidate you.
The MA 4 is a high-quality general-purpose amplifier and connects like any other.
