Chapter 3 Connection and operation
3.1 Input/Output
Connecting knowledge:
For input, use the shielded wire with high
shielding layer density;
Balanced connection to reduce noise
interference;
For unbalanced connection, the shorter the
cable is the better. Maximum length does not
exceed 3 meters;
Keep signal cables isolated from power cable
and PA output cable to avoid noise;
Please power off all devices before changing
connection; otherwise it may cause damage
to the hearing and loudspeakers.

Figure: bridge mode
Note: HPA-160A/02 has no Dante function.
3.3 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).
3.3.1 Protect speaker
Clipping not only makes the sound quality worse, but
also damages the treble unit.
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 use. 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.
3.3.2 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;
To Dante network
5

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. 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;
7. Do not use PA below the nominal load, too low
load may cause PA output protection and
premature clipping may damage the speaker;
8. 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.
