MC2 Audio E4-75 Owner's Manual page 10

Channels C & D +ve = channel D +ve (pin +1 on connector D or +2 on connector C)
-ve = channel C –ve (pin -1 on connector C)
Note: Both level controls must be set to the same position.
When operating in bridged mode, the minimum impedances are 8 ohms.
Note: 1. Negative (-ve) output terminals must not be joined together, since they are not both at
0V.
2. Because the currents involved are very high, the speaker cables should conform to the
following minimum requirements, otherwise the losses will cause the cables to get hot
and audio power will be reduced:
3. Do not connect the inputs/outputs to any other voltage source such as a battery,
mains source or power supply, regardless of whether the amplifier is turned on or off.
3. Do not run the output of any amplifier channel back into another channel's input and
do not parallel or series-connect an amplifier output with any other amplifier output.
E4-75 - 14A into 4 ohm speaker loads.
