Connecting to Power Supply
DANGER
Electric shock caused by short-circuit
The device accepts AC mains power at 100–240 V and 50/60 Hz. Do not supply power at any other
voltage or frequency to the device.
This device falls under IEC protection class I. Make sure that the device is always electrically connected
to the ground (earth).
Before connecting the device to the socket-outlet:
Make sure that the power supply matches the input voltage specified on the information label on
the device.
Make sure that the socket-outlet has ground (earth) connection.
Connect the device to the socket-outlet with the power plug.
Power Linking of Multiple Devices
This device supports power linking. Power can be relayed to another device via the power OUT
connector. Note that the input and the output connectors have different designs: one type cannot be
connected to the other.
Power linking of multiple devices must be carried out only by instructed or skilled persons.
WARNING
Incorrect power linking may lead to overload of the electrical circuit and result in serious
injuries and damage of property.
To prevent overload of the electrical circuit, when power linking multiple devices:
Use cables with sufficient current-carrying capacity. The power cable supplied with the device is not
suitable for power linking of multiple device.
Make sure that the total current draw of the device and all connected devices does not exceed the
rated capacity of the power cables and the circuit breaker.
Do not link more devices on one power link than the maximum recommended number.
Maximum recommended number of devices:
at 100–120 V: 5 devices
at 200–240 V: 10 devices

5. Operation
Safety Instructions for Operation
Attention
This device must be used only for the purposes it is designed for.
This device is designed to be used as an active subwoofer. It is suitable only for indoor use.
Any other use, not mentioned under intended use, is regarded as non-intended and incorrect use.
Switching On/Off
The device has a power switch.
●To switch the device on, press the power switch (11) in ON position.
●To switch the device off, press the power switch (11) in OFF position.
DSP Settings
The NRG-12SA has an internal DSP (Digital Signal Processing) which optimizes the output sound
depending on the type of the input sound source. If you use the device with active full-range speakers
from the NRG range, you can use one of the factory presets for the respective model.
Press the DSP button (04) repeatedly to select one of the 4 options. The LED indicator of the selected
option lights up.
●NRG 8A: Use this setting when the device is connected to an NRG-8A
active full-range speaker
●NRG 10A: Use this setting when the device is connected to an NRG-10A
active full-range speaker
●NRG 12/15A: Use this setting when the device is connected to an NRG-12A or
an NRG-15A active full-range speaker
●Sub Filter: Use this setting when you want to adjust manually the crossover
frequency. See 5.4. Adjusting the Sub Filter on page 18
Adjusting the Sub Filter
You can manually adjust the crossover frequency of the device so that it matches the specifications of
the connected full-range speaker.
To adjust the crossover frequency:
Select the option Sub Filter with the DSP button (04). See 5.3. DSP Settings on page 18.
Turn the sub filter frequency control (05) to set the crossover frequency. The adjustment range is 80–
170 Hz.

19
NRG-12SA
Product code: D3657
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.
5.7. 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
6. Troubleshooting
This troubleshooting guide contains solutions to problems which can be carried out by an ordinary
person. The device does not contain user-serviceable parts.
