System installation
1. In order to achieve the best operation of the equipment, the height of the
receiver should be higher than 1 meter from the bottom and at least 1
meter from the wall surface.
2. Keep the antenna away from interference sources, such as computer
equipment, digital equipment, televisions and cars, and also away from
large-area metal objects.
3. Install the antenna on the antenna connector on the rear panel, and pull
the antenna to a position at a 45° angle to the vertical.
4. Minimize obstacles as much as possible between the location of the
receiver and the place where the transmitter is used.
5. When two transmitters are used at the same time, the distance between
the transmitter and the receiver must be at least 2 meters.
System connection
1. Connect the output end of the DC12V/1000mA DC output power supply to
the transmitter DC power input socket. To prevent the DC plug from
accidentally detaching, first pass the wire through the fixing hole and then
tighten it.
(Note: The input voltage of the AC power adapter must be selected to meet
the power supply specification range of the area of use.)
2. There are two types of audio jacks on the rear panel of the transmitter,
namely Φ6.3mm balanced output socket and XLR-3/6.3 mm combined
balanced input jack.
Use a suitable cable to connect the output of an external device (such as
a mixer or a second PM-320TX) to the XLR-3/6.3 mm combined balanced
input jack.
Use a suitable cable to connect the input end of an external device (such
as a mixer or a second PM-320TX) to the Φ6.3 mm balanced output jack.
(Note: After the signals of the input jacks BAL AF IN 1/L and BAL AF IN 2/R
are separated, they continue to be transmitted to the output jacks LOOP
OUT BAL 1/L and LOOP OUT BAL 2/R. Therefore, you can only transmit
Use the output jack when the machine is switched on. )
3. Set the appropriate audio input level
The intensity of the audio input signal will be displayed on the AF level
meter on the OLED display panel, and the intensity of the input audio
signal will be adjusted appropriately. Therefore, the input intensity must be
adjusted appropriately to obtain the best signal-to-noise ratio and dynamic
range, and to avoid signal distortion.
4. Headphone connection
Insert the monitor headphone connection plug into the 3.5mm headphone
stereo socket, you can also connect general headphones or connect the
output end to the audio input of other audio equipment.
Note: The headphone output socket is a stereo output. Note that the
connected plug must be a stereo plug. If it is a mono headphone plug, one
side of the output may be short-circuited and the headphone output circuit
on the other side may be burned.
5. Multi-system mixed group connection mode
Some performers need to hear the signal of their own playing instrument
and the mixed instrument. With the help of this device, each performer can
hear this combination” effect or their independent performance effect,
and send a whole band from the mixer Mix the effect to the first transmitter
(PM-320T) BAL AF IN 1/L and BAL AF IN 2/R input terminals, and then
from the LOOP OUT BAL 1/L and LOOP OUT BAL 2/R output terminals,
connect To the BAL AF IN 1/L and BAL AF IN 2/R inputs of a transmitter.
Using this link, you can operate all transmitters, and create a mixer to
listen to each performer through the auxiliary output of the mixer. Send
these different combinations to each performer’s receiver (PM-320R).
