External loudspeakers connection
The minimum recommended load per amplifier is 3.2 Ohms and the maximum is 16Ohms.
It is possible to use a load of 2 Ohms but it will result in increased distortion and loss of output power.
Any combination that gives a total load between 3.2 and 16 Ohms is acceptable.
Note the phase (+ sign or Red dot) of the speakers, or loss of sound quality will occur.
Note: never connect the two speaker outputs together in any way or connect them to ground.
This may cause severe damage to the amplifiers.
Examples of loudspeaker connection:
5 Speakers of 16 Ohms each
6 Speakers of 16 (8) Ohms each
Total load of 3.2 Ohms
Total load of 10.6 (5.3) Ohms
8 Speakers of 16 (8) Ohms each
8 Speakers of 4 (8) Ohms each
Total load of 8 (4) Ohms
Total load of 8 (16) Ohms
Extension cables
The microphone cable may be extended up to 30 meters.
If extended further, noise and ”hum” may distort the signal.
There will be no damage caused to the unit.
The loudspeaker cables can be extended up to 30 meters with 0.75mm² cable or 50 meters with 1 or 1.5mm² cable.
If extended further, loss of sound quality may occur, but no damage will be caused.
Beware of polarity of speakers, or loss of sound quality will result.
