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
