4. Installation
(1) System Installation
LOOP Applications
Use the Loop OUT L (left) and R (right) outputs to send a copy of the audio signal
going into the transmitter to other devices. Shown here are a few examples of the
many configurations for the LOOP outputs.
NOTE: The input level control and the input pad do not affect the level of
the LOOP signals.
Stereo for multiple Systems
Use the LOOP OUT connectors to send one stereo signal from the mixing console
to multiple IEM 4.16-RX wireless transmitters. This frees up outputs on the mixing
console for other uses.
Connect the first transmitter to the mixer.
Connect the next transmitter to the first transmitter‘s LOOP outputs. Form
a chain using all transmitters in your installation.

Mix Mode for Multiple Systems
Some performers need to hear more of their own voice or instrument while others
want to hear more of the band. With this setup, each performer hears a
combination of the whole band and their own instrument and the performer can
use the receivers balance control to create the desired mix of the whole band to
input 2 of the first transmitter. Connect input 2 of the next transmitter to the
LOOP OUT R output of the first transmitter. Continue the chain with all the
transmitters. Next, create sole mixes for each performer using the auxiliary
outputs of the mixing console. Send these mixes to input 1 of each performers
transmitter

(2) Power Installation
Connect the output port of the DC12V-15V/800mA to the input of the DC
Power of the transmitter.
(3) Turn On Power
Press the power button and the LCD will illuminate, meanwhile more
information will be displayed and will output the transmitting
signal once the PLL circuitry is locked

(4) Audio Signal Input
Optional stereo and mono channel input, mono channel input from AF II IN of the
right side, you can choose XLR-3 balanced input or 6.3 unbalanced input
connector.
(5) Configuring Suitable Audio Input Standard
The strength of the audio input signal will be display on the LCD panel, you
can set the strength to show 8 bars and when the strength is over the 8
bars the input signal will be limited even when the signal is stronger. By
doing this you can obtain the best S/N ratio and dynamic range by
adjusting the input strength to avoid distortion.
(6) Setting Frequency of the Transmitter
a. Press the UP and DOWN button, the system will change the frequency
and channel according to the preset menu. When the LCD displays the
frequency the channel will also change. When the name appears the
system is changing automatically according to the frequency or channel.
b. Press UP and DOWN button to the desired frequency or channel you re
quire. The frequency or chanel you have chosen will begin to flash
c. Press SET button and the frequency or channel has been fixed and the
CPU will lock the frequency the LCD will stop flashing and will revert to
it’s orignal status.

(19) Switch for Sound Mode
To choose the current headphone output for stereo or mono channel, it should
be consistent with the transmitter
Notice: when choosing the stereo sound mode, you will have better
sound behavior but an increase in S/N when choosing single output mode, the
S/N will be larger and will increase distance

6. Notice
(1) When this system is being used together with a wireless
microphone system, please avoid the same frequency range to prevent distortion
(2) Please make sure that there are no obstacles between the antenna of the
transmitter and the receiver. When used indoors the obstacles will absorb wave form
that will shorten the transmission distances
(3)Connect the transmitting signal to the external antenna with coaxial cable, the
coaxial cable should be 50Ω, generally 5 meters RG-58
(4) The working life time for the battery depends on the output volume power of the
headphone and choosing a headphone with better sensitivity will increase battery life
(5) The voltage of the power supply should exceed 12V and less than 18V while
making sure that the output current is over 500mA
(6) Please remove the batteries when not in use over a long period of time.
