2. Connect the audio source, such as a mixer.
Connect the mixer output to the XLR /ɑ6.3mm combo
input in the Front panel of SIEM-2T with the AF input
cable.
NOTE: Two balanced XLR /ɑ6.3mm combo inputs are
provided. You may use either one or both for a stereo source.
Also, two balancedɑ6.3mm loop out connectors are provided
for multiple systems application.

2. Connect with the earphone IE-1
(1) Plug the earphone into the jack of the receiver.
(Figure 1)
(2) Make sure the volume is at low level to avoid injury
to your ears.
(3) Insert earphones into your ear at a correct position.
(Figure2)
(4) Check if the silicon sleeve is suitable for your ear. If
not, replace with other sizes of sleeves for comfort
and best isolation. (Figure 3)
(5) Make sure correct channels are chosen. The letter
“R” and “L” on the earphones indicate the right and
left ear respectively.

7. Installation
Here are some basic operation modes for your reference.
Also, you may make use of the loop out connectors for
multiple systems application.
1. Connect the mixer outputs to inputs of the first transmitter.
2. Connect loop out connectors of the first transmitter to the
second one.
3. Connect subsequent systems in the same way.
1. Set for Multiple Systems
2.Mix For Multiple Systems
This installation enables each performer to create their own mix.
1. Send the band mix to input (Right / CH.2) of the first
transmitter.
2. Connect loop out connector (CH.2) of the first transmitter to
input (Right/CH.2) of the second transmitter.
3. Connect individual solo mix to input (Left/CH.1) of each
performer's transmitter.

8. Recommendations
1. In order to achieve the optimum reception and also extend
the operating distance, please leave an “open space”
between the receiver and transmitter.
2. Keep the devices away from the metal objects or any
interference sources, at least 50 cm.
3. Remove batteries from the battery compartment when the
receiver will not be used for long time.
4. When you need to replace the batteries, please replace both
batteries at the same time with new ones.
