EV Rider MA-1212 - Manual (Page 2)

A 24V DC power source (i.e. a battery) has to be connected to the terminals (13) that are covered by a
protective lid. To reduce the risk of dropping voltage to a minimum and to eliminate the danger of damaging
Switching the amplifier on or off is performed through the power switch (6).
At all times, the amplifier has to be operated under appropriate conditions. This includes that the
