Instruction manual MA120 - MA240

The 4 ohm and 70 volt connectors are not used. Connect the
common or speaker line ground wire to the COM connector.
Connect the 100 volt line to the 100 volt connector.
The minimum speaker line impedance is 83.3 / 41.7 ohms
(120 / 240W).
Check the impedance with an impedance meter before connecting
the speaker line to the amplifier.
Practical example
Connecting the speakers
Example: 100 volt speaker line.
Connect the speaker line wires
as shown.
Note: never use more than one output at a time ! Do not overload
the speaker output. In 70 and 100 volt speaker lines, the power of
all speakers in the chain must be added. The total power MUST be
lower than or equal to the amplifier’s output power. For example:
on a 240 watt 100 volt amplifier, you can connect 4 x 60 watt
100 volt speakers in parallel: 4 x 60 = 240 watts.
Always measure the speaker line with an impedance meter or
speaker line watt meter
