Operation
Install fresh batteries in the transmitters (fresh to the section relative to the
specific transmitter you are using).
Connect the AC power adapter to a wall outlet and to the back of the receiver.
Screw antenna A, B in, and position them 60 degrees apart from each other.
Connect one of the two outputs available at the back panel to the next stage
in your system. Typically, use the1/4”output to connect to unbalanced
equipment such as consumer level receivers, amplifiers, and mixers. Connect to
professional equipment using the XLR output (cable not included).
Make sure the volume of your speaker is off, turn on the receiver and the
transmitters. Press SET button. You will see LCD screen shows “IR---”
status. Aim the transmitter’s IR at the receiver’s IR window. Once the pair up
is completed, frequency will be shown on the LCD screen. On top of frequency,
you can also see group number and channel number.
Press up or down button to select the desired frequency, then press
“SET” again to confirm setting and pair up.
You can use multiple receivers at the same time, and set all the transmitters
to different channels. There are 100 channel selections available for this system!
For better result, keep the transmitter at least 2’away from the receiver but
within the transmitter’s range (80m/260ft). Keep the transmitters in a direct line
of sight with the receiver whenever possible.
Electronics devises such as mobile phones, radios, and other transmitting devices
may interfere with the wireless system transmitters. Please keep transmitter and
receiver away from those devices and other possible interfering sources.
