System installation and connection

System installation

1. In order toachieve the best operationof the equipment, the height ofthe receiver should behigher than 1 meterfrom the bottom andat least 1 meterfrom the wall surface.
2. Keep the antennaaway from interference sources, such as computerequipment, digital equipment, televisions and cars, and also awayfrom 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 muchas possible between thelocation of the receiverand the place wherethe transmitter is used.
5. When two transmittersare used at thesame time, the distance between thetransmitter and the receivermust be at least2 meters.

System connection

1. Connect the outputend of the DC12V/1000mADC output power supplyto the transmitter DC powerinput socket. To prevent theDC plug from accidentallydetaching, first pass the wirethrough the fixing holeand then tighten it.
   ( Note: The input voltage ofthe AC power adaptermust be selected to meetthe power supply specificationrange of the areaof 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.
   1. Use a suitable cable to connectthe output of anexternal device (such as a mixeror a second PM-320TX) to theXLR-3/6.3 mm combinedbalanced input jack.
   2. 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 signalsof the input jacks BAL AFIN 1/L and BALAF IN 2/R areseparated, they continue to betransmitted to the outputjacks LOOP OUT BAL1/L and LOOP OUTBAL 2/R. Therefore, you can only transmit. Use the output jack whenthe machine is switchedon.)
3. Set the appropriateaudio input level
   The intensity of theaudio input signal willbe displayed on theAF level meter onthe OLED display panel, andthe intensity of theinput audio signal willbe adjusted appropriately. Therefore, the input intensitymust be adjusted appropriately to obtainthe best signal-to-noise ratio anddynamic range, and to avoidsignal distortion.
4. Headphone connection
   Insert the monitor headphoneconnection plug into the3.5mm headphone stereo socket, youcan also connect generalheadphones or connect theoutput end to theaudio input of otheraudio equipment.
   Note: The headphone output socketis a stereo output. Notethat the connected plug mustbe a stereo plug. Ifit is a monoheadphone plug, one side of theoutput may be short-circuitedand the headphone output circuiton the other sidemay be burned.
5. Multi-system mixed groupconnection mode
   Some performers need tohear the signal oftheir own playing instrumentand the mixed instrument. Withthe help of thisdevice, each performer can hearthis "combination" effect ortheir independent performance effect, and send a whole band fromthe mixer Mix theeffect to the firsttransmitter (PM-320T) BALAF IN 1/L andBAL AF IN 2/Rinput terminals, and then from theLOOP OUT BAL 1/Land LOOP OUT BAL2/R output terminals, connect To theBAL AF IN 1/Land BAL AF IN2/R inputs of a transmitter. Using this link, you can operateall transmitters, and create a mixerto listen to eachperformer through the auxiliary output of the mixer. Send these different combinations to each performer's receiver (PM-320R).
