Power and Warranty
Power Requirements
In the factory configuration, NS
160/NS380 are fit for 50Hz/220v
alternative power. Please make sure
that the voltage shown on the power
label of the AC input connector on
the back panel is consistent with the
supply voltage before using.
If the connected AC voltage is not
consistent, it may cause danger of
fire or safety problems, and
damage to the device. If you have
any question about the voltage
requirements or the regional voltage,
please consult the local authorized
dealer before connecting to the
mains.
warning：please make sure that all
the components of your audio
system have stable connection to
earth. Please do not use the “earth
disconnector”, for it damages the
safety plug or grounding plug.
Otherwise dangerous voltage will
generate between components and
may cause damage.
Note：NS 160/NS380 are capable of
producing breathtaking sound at a high
power. But your power supply may be a
marring factor for the sound due to your
listening habits or the number of
speakers and amplifiers in you audio
system. In this case, you may install a
dedicated AC circuit. If you have
multiple AC circuits for power supply,
please consult a qualified electrician to
ensure all components operate with the
same, stable and low-impedance
earthing reference. Unplug Model One
from the AC wall outlet during a
lightning storm or when not in use for an
extended period of time.
Warning: Before moving the device,
please remove the plug from the AC
power outlet and unplug the power
cord from the back panel to ensure
that the device is powered off.

Front Panel
1Power SW：Press the power switch button to boot the apparatus. Press
again, the apparatus goes into stand-by mode. In stand-by mode, the circuits
and components inside need only low voltage to operate and the power
consumption and heat generated are very little.
2Indicators: The indicators will be inactive in stand-by mode, and will
remain active in operation.
Back Panel
1Pre amp input: Input the pre amp signal to this terminal via high-quality
XLR signal wire. Please notice the right and left channel with the mark R(right
channel) and the mark L(left channel).
Note: please do switch off the main power before connect /
disconnect the signal wire.
2Speaker output: connect this terminal to the speaker via high-quality
speaker cable. Please notice the “+” and ”-” polarization and the left and right
channels. The mark “+”=positive, “-”= negative, “R” = right channel, and “L” =
left channel.
Note: please mind the right polarization, and the wrong polarization
will damage the apparatus. And switch off the main power before
connect / disconnect the speaker cable.
3Power input: input AC power into the apparatus via standard power
cable.
Note: the nominal voltage of the apparatus is 220V/50Hz AC power,
please make sure your wall socket meets the specifications.
4Power Switch: “-” = switch on, “O” = switch off. When you flip the
button to “-” position, the apparatus goes into stand-by mode.
Note: the left and right power of NS380 are separate, and you have to

XLR balance input plug pins
1. Earth pin
2. Signal + (positive phase)
3. Signal - (negative phase)
Connection

damaged or even transistors burned out. If you convert to single-ended input
at your own risk, any damage caused to the power amp or other connected
units will be not covered by the warranty.
2. Connect the speaker cable to the loudspeakers with the right polarization
and left and right channel connection.
3. Connect the power cable to the main power socket.(220V/50Hz).
Note: Do not switch on the main power before all the components are
well connected and keep the positive and negative poles of the speaker
cable separate from each other.
Power on
If all the components are well connected, power on the device by flipping the
power switches on both sides to the “-” position. Press the switch key on the
