NOTE:

The dual + and -- subout terminals of the

 

750d/1500d are paralleled internally

 

and the combined load impedance

 

should be taken into consideration when

 

connecting multiple subwoofers.

 

The audio signal to the slave amplifier is

 

180° out of phase. The subwoofer’s

 

negative terminal must be connected to

 

the slave amplifier’s positive terminal.
