BOAZU to SUBWOOFER

When adding a subwoofer to a system with a Boazu integrated amplifier, the subwoofer needs to have high level inputs. It’s not possible to connect a subwoofer in any other way.

When connecting the high level inputs to the speaker outputs of Boazu, it is vitally important to use the following scheme, or fatal damage can occur to both your sub and Boazu:

The wire (often blue or black) that is ‘Left –‘ should go to Left Red (+) on Boazu
The wire (often yellow) that is ‘Left +‘ should go to Left Black (-) on Boazu
The wire (often red )that is ‘Right +‘ should go to Right Black (-) on Boazu

The subwoofer should then be set to phase inverted.

 
BOAZU to LOUDSPEAKERS with ACTIVE AMPLIFICATION

If your loudspeakers have active amplification inside – most commonly driving the bass units – and the signal for this amplification is taken from the regular speaker terminals at the rear, it’s vitally important that you connect your Boazu in the correct way. Please continue reading below!

The BLACK speaker output of Boazu is actually the signal.
The RED speaker output of Boazu is ground.

If your loudspeakers with active amplification only have black and red terminals at the rear, then most likely the BLACK (-) input will be connected to GROUND inside the speaker’s amplifier. If you connect black on your Boazu (signal) to black on your speakers, Boazu will be feeding the signal (and lots of current) into ground, which will cause Boazu to run very hot and potentially cause damage. Instead, you must connect this way:

RED speaker out on Boazu connects to the BLACK (-) input on your loudspeaker
BLACK speaker out on Boazu connects to the RED (+) input on your loudspeaker
