3 Connections
Only three connections need to be made: mains power, audio input signals, and loudspeaker
leads. Do not make any connections to the amplifier or to any preceding equipment with the
amplifier switched on!
3.1 Mains Power Connection
The DS50 is internally selectable for 110-120/220-240V 50/60Hz mains voltage. The mains
voltage is configured at the factory according to standard used in the country of destination. The
exact voltages are stated at the rear of the amplifier. Switching between mains voltages has to
done by an authorised Stage Accompany service centre. Connecting to the wrong voltage is
dangerous and may damage the amplifier. Always ensure that you use a correctly grounded
power supply. If more than one DS50 is to be used, it is advisable to connect each one
separately to the nearest mains supply in stead of connecting several DS50s using an adapter
block (see figure 3-1).
