5. OPERATION
Warning: Before turning on the unit,
please make sure the unit is power off,
the power switch is in the "OFF/off" posi-
tion, and all the volume knob has been set to the
lowest position.
Speaker protection
Clpping not only make thw sound worse, but also
will damage the high frequency drive unit. It is rec-
ommended you that don´t do the clipping to the
unit´s signal to protect the speaker. In addittion,
to avoid the speaker drive circuit burned which is
caused by the strong infrasound signal transmis-
sion of the unit, breathing or the high level which
is caused by the dropping of the microphone and
the low frequency signals. It should take one of
the followings ways:
1. Install the high-pass filter between the mixer
output and unit input.
2. Use the buil-in DSP to set the high-pass filter
(only for the unit with DSP).
3. Install a high-pass filter at the sides of the mix-
er. At the premise of without affecting the
use, set the filter frequency as high as possi-
ble. For example, for music is set to 35Hz, for
the microphone is set to 75Hz. I each mixer´s
input channel, set the frequency of the filter
with the relevant channel below the lowest
fundamental frequency.
Warning: Do not put the sensitive high-
gain devices (such as tape deck) above
or below the unit directly. This will form
a strong magnetic field to cause a "buzzing"
sound near the unshielded device. If you use a
cabinet, we recommend you to place the sensi-
tive devices at least 20cm to the units.
Start-up procedure
According to the users needs, please follow the
connection illustration section of the stereo,
bridge or mono mode of the manual to install,
if it is necessary to change the mode, please
disconnect the power supply.
