Product code: D3659 

 

Adjusting the Phase 

The device has a phase switch. You can reverse the phase if the bass response is too weak.  

Slide the sub phase switch (06) up/down to choose one of the 2 options: 

 

0°: 

normal phase – the subwoofer and the main speakers are in phase, which creates a strong 
bass response 

 

180°: 

reversed phase – the sound waves of the subwoofer are inverted compared to the rest of 
the speakers. This setting helps reduce any phase cancellation due to the physical 
distance between the speakers 

 

Adjusting the Gain 

Turn the sub master gain control (08) to the left/right to decrease/increase the master volume. This setting 
affects the overall volume.

LED Statuses 

The device has 4 status LED indicators (07). The LED indicators have the following statuses: 

 

 

Protect:   Illuminates when the amp is overloaded. This can happen when the 

input signal is too high or when the ambient temperature is too high. 
Decrease the volume of the connected device 

 

Limit:  

Illuminates prior to the amp clipping and distorting. Adjust the input 
levels so that this LED indicator illuminates only briefly during the highest 
peaks. If you operate the device with this indicator continuously on, this 
will result in degraded sound quality and could damage or reduce the 
service life of the components 

 

Signal:  

Illuminates when signal is present 

 

Power:  

Illuminates when the device is powered on
