Chapter 3 Connection and operation

Input / Output

Connecting knowledge:

• Input wire use the shielded wire with high shielding layer density;

• Input signal use balanced connection, to reduce noise interference;

• If using unbalanced connection, the shorter the better, had better not exceed 3 meters;

• Signal cable should avoid go together with power cable and PA output cable, to avoid noise;

• Please power off all devices before change connection; otherwise it may cause damage to the hearing and speakers.

• Connection diagram: balanced analog input
  

• Connection diagram: unbalanced analog input
  

Stereo mode

MONO mode

Bridge mode

Note:

In the bridge mode, the DIP switch is set to MONO, the signal is input from the A/C channel, and output from the A/C, and the output terminal is connected to 1+ 2-;
The constant voltage output setting is the same as the bridge output setting.

Operating instructions

Please confirm before installation:

• The power cord not connected to the power socket;
• The power switch is off;
• Volume knob turned off (counterclockwise to limit).

Protect speaker

Clipping not only makes the sound quality worse, but also damages the treble unit (the “Clip” indicator will be turned on when clipping), you can reduce the input signal level to avoid clipping.
The speaker drive circuit may be burned by strong infrasound signal. The sound of breathing and the high level and low frequency signal caused by the dropping of the microphone are typical infrasound signals. To prevent infrasonic signals, one of the following methods should be used:

• Install high pass filter between the mixer output and PA input;
• Open the high pass filter in the mixer. Set the filter frequency as high as possible without affecting the using. For example, set to 35 Hz for music signal and 75 Hz for microphone signal. For each mixer input channel, the filter frequency is set below the minimum fundamental frequency of the related channel.

Matters need attention

Although PA will be protected under exceptional circumstances, please pay attention to the use of PA in order to achieve the best performance and maximum safety:

1. It is necessary to configure PA before use, including the connection of input and output cables, improper wiring will result in equipment failure;
2. Before turning on the power supply of the device, make sure that the volume control knob is adjusted to the minimum. Otherwise, sudden bursts of sound may damage your hearing;
3. Do not connect the ground wire of the output cable and the ground wire of the input signal, which will form ground loop and cause oscillation;
4. Do not connect the output to the power supply, battery or mains supply. Otherwise it may cause an electric shock;
5. Tampering with the circuit or unauthorized modification of the circuit can be dangerous and cause all services provided by the agent fail;
6. Do not use PA when the yellow “Clip” LED blinks continuously;
7. Please do not make mixer overload, otherwise it will send the clipping signal to PA, and PA will precisely reproduce these signals and speakers may be damaged;
8. Do not use PA below the nominal load, too low load may cause PA output protection and premature clipping may damage the speaker;
9. When PA is switched on, the output interface may have a fatal voltage.
   Note: TAIDEN is not responsible for any damage caused by excessive use of other system components.

Heat sinking

Heat sinking method: Cold air intake from front panel vent, flow through the heat sink and take away heat, and discharge from rear panel. In order to have a good heat sinking, please put the device in 0 – 40 °C environment, and make a smooth ventilation between the front and rear panel. Reserved space shall not be less than: side 5 cm, rear 10 cm.
If the temperature of the internal heat sink is more than 70 °C, the power limit function will be activated, and the output power will be reduced to avoid excessive temperature rising. If the temperature of the internal heat sink continues to rise to more than 85 °C, PA will be protected and the output will be turned off. When it drops to a safe temperature, PA will start automatically.

Troubleshooting

The following table lists the main reasons for the abnormal work and treatment measures, as well as the circuit protection in each case.

insert it firmly
Rear panel breaker disconnect| Check the circuit breaker and reset it
PA power switched off| Check the front panel power switch and place it in the “On” position
“Power” indicator blinks| AC voltage low| Check AC cable
“Fault” indicator on| Short circuit in speaker terminals, PA output terminals or speaker cable| Locate the short circuit and eliminate the short circuit.
PA overload| Supports 4 Ω and above speakers system c
“Clip” indicator on| Input signal is too high| Lower input level
Power off  during operation (All indicator off)| PA output DC voltage| Consult your local service center
