Features：
Network power amplifier
1. The network audio power amplifier is a constant voltage power amplifier with built-in 2
channels. It is also an audio terminal encoding and decoding device that can receive network
audio sources, collect local RCA, MIC mixing input, and achieve functions such as controlling the
output audio sources of different channels;
2. Comes with dual network ports, which can be accessed from any place with an Ethernet
interface. It can play network audio and can accept access and control from servers and other IP
network devices;
3. Network fault self-diagnosis, network and service status display;
4. Powerful network audio playback function, which can be used independently in the network,
and can directly play network audio signals from IP network servers and IP network acquisition
terminals;
5. Independent power supply, independent power design is adopted for the control board and
power amplifier board, even if one fails, the normal use of the other will not be affected;
6. Strong cut function, when the fire signal is activated, it will automatically output 24V electric
signal and three-wire strong cut signal to turn on the volume controller, no need for additional
equipment;
7. 2-channel 600/450/300/150W independent power amplifier;
8. Special power amplifier detection function, the network can monitor the power amplifier
status in real time;
9. With power amplifier backup function, the system can achieve switching Master/Slave
Amplifiers automatically when one become fail.
10. With two local RCA, local MIC mixing input function;
11. No signal automatically into standby state, energy saving and environmental protection;
12. Provide complete overheating and overcurrent protection of the whole machine;
13. Work signal indicator, local volume control, color display screen;
14. Network parameters can be configured locally;
Note: Only the power is different between different models, other functions are the same,
please see the function parameters for details.
Accessory:
The product contains a separate AC power cord for powering the product.

1. PA (Power amplifier output switch)
When the power amplifier module is powered on, press this button to power off the power
amplifier module; when the power amplifier module is powered off, press this button to power
on the power amplifier module.
2. SELECT/PUSH (single button shuttle)
In general, press this button to select the volume, rotate it to the right to increase the volume,
rotate it to the left to reduce the volume, press this button again to lock the volume after
adjustment (or wait for 3S), and long press this button to enter the next interface.
3.LCD display
Display status information, parameters and other information of the power amplifier.
4. LAN network status indicator
When the local network is connected to the server normally, the indicator light is on.
5.CH2
Display the working status of channel 2. When the AUX2 channel is in the working state, the
signal light is always on and normally displays; when the power amplifier is protected or the
power is off, the indicator light is red.
6.CH1
Display the working state of channel 1. When the AUX1 channel is in working state, the signal
light is always on and normally displays; when the power amplifier is protected or the power is
off, the indicator light is red.
7. POWER (power indicator light)
Used to indicate the power status of the device.

The Rear Panel
1. AC power interface
AC 220v power supply.
2. Main power switch
Control the power supply of the entire device.
3. Strong cut volume control wiring terminal
Used to connect the speaker line with a three-wire volume controller. When a fire alarm linkage
signal is triggered, it will automatically output a strong cut signal to turn on the volume
controller.
4. Backup audio input interface
Used to connect to the backup power amplifier. When the main power amplifier is detected to
work abnormally, it will automatically switch to the backup power amplifier. Please correctly
connect the backup broadcast cable according to the label.
5. Fire dry contact trigger signal input
Linkage with fire signal.
6. Dry contact signal output
When a fire alarm linkage signal occurs, this port will have a set of dry contact signal output.
7.24V power output
When a fire linkage signal occurs, this port will have a 24V DC output.
8.AUX1/AUX2 input
Please connect an external audio source to this input port, the channels are independent of
each other
9.MIC1/MIC2
Local microphone input port, the channels are independent of each other.
10.10M/100M dual network ports
Used to connect to a local area network, equivalent to a two-port switch (hub), it is
recommended that customers use a standard network.

Other problems
Common problems and solutions for power amplifier failure:
Network power amplifier
Press the switch on the front panel of the
device to supply power to the amplifier to
make the amplifier enter the normal state.
Open the cover to replace the fuse in the
power module. Please replace it with a fuse
of the same specification.(This operation
should be carried out by personnel with
maintenance qualification)
Connect all speakers correctly to ensure
that the total power of the speakers
does not exceed the rated power of the
amplifier. At the same time, when the
speaker cable is too long, the loss caused
by the line needs to be considered.
Turn off the power of the amplifier and
check the speaker line to ensure that the
speaker is properly connected and there
is no short circuit.
Observe whether the fan in the case works
normally, turn off the power amplifier, and
wait for the temperature in the case to
decrease before turning on the amplifier.
Power amplifier
failure
Check the cause of the power amplifier failure;
If it is always under protection state, please contact Thinuna
directly or a local after-sales service organization certified
by Thinuna.
Equipment parameter adjustment:
