Characteristic of MI-808T：
MI-808T is a wireless monitoring system designed specially for people in
stage performance and broadcasting. Main purpose of this system is to allow
people to listen to their audio sources easily instead of via complicated audio
cables or monitoring speakers. In addition, MI-808T can serve as conference
PA system or multi-lingual translator. To increase audio quality, S/N ratio, and
dynamic range, MIPRO adopts "Dynamic Signal Processing Technology" to
limit noise level to its minimal.

4. Operating MI-808T：
3.Installation of Power Supply
1.Installation of Antenna
Connect output end of DC 12V~15V/1A power supply with input socket of AC
power of transmitter. To avoid the fall off of DC plug accidentally, getting through
linking cable from fix hole and then fasten it.
Install coaxial cable on the transmitter will reach the best transmission effects but
it must notice frequency consistency for both antenna and transmitter.
4.Turn on the transmitter
When turn on the power switch, the green LCD display will be bright and show all
information on it. Transmitter will output transmission signal if PLL circuit is locked.
5. Line-in Level input
It can select stereo or mono Lin-in input, the signal will input from AF IN of right
side. It can select XLR-3 balanced input jack or 6.3mmφ unbalanced input jack.
Because of compound socket, it is available for both type of jacks.
2.Installation of Front Antenna
Cause:
The strength level of signal input is LINE LEVEL. It must magnify the signal
before input if MICPHONE LEVEL input is necessary, otherwise sensitivity is
insufficient. Suggest to connect with monitor output jack of mixer.
Select FB-71 Rack mount kit, use one end to connect with output socket of
transmission signal and the other end connect with transmission antennas. The
transmission effect will enhance if install antennas in front of the panel.
6. Set up appropriate LINE LEVEL
The strength of LINE LEVEL input will show on two bar of LINE LEVEL list of left
side. Adjust the strength of output appropriately to light up three lamps. The maximum
of display of LINE LEVEL would not exceed four lights. When input strength exceeds
the strength of four lights, the red light will light up; and then input signal should be
limited and modulation should not increase.
Therefore, adjust appropriate input
strength to obtain the best dynamic range and S/N ratio and avoid signal distrotion.

13. Rack Installation of 2 Units of MI-808T
5. Important Notes：
A) Single half-rack transmitter
① Screw the fixed rack mount ear on Left and R i ght sides. Please see below
illustration for correct assembly. (Fig. 5)
1.
Don't use same frequency band for both monitor and wireless microphone
system when they work simultaneously.
2.
It must use 50Ω coaxial cable to connect the transmission signal to
exteral antennas. Avoid to use long cable exceeding 5 meters when use
RG-58 or 3D cables.
3.
It is better to maintain non-barrier sight distance between transmission
antennas and receiver. This distance will shorten once there are too
many barriers to absorb electric wave and objects.
4.
When using DC power supply, please be aware of the operating voltage.
Please make sure minimum of 12 volts can be obtained for function
properly. However, the power supply should not exceed its maximum
capacity of 18 volts. When the supply voltage is too high, the system will
suffer severe internal damange. It is preferred the power source is from
a regulated power with the minimum current of 500mA.
( (fig. 5)
B) Dual half-rack transmitters
① Remove the screws of top and bottom of the two transmitters
counterclockwise.
② Position the connect plates between the top and bottom of the two
transmitters and tighten.
③ After joining the two transmitters together, screw the optional accessory rack
mount ears (FB-72) on left and right sides. (Fig. 6)
Notice :
The changes or modifications not expressly approved
by the party responsible for compliance could void the
user's authority to operate the equipment.
IMPORTANT NOTE:
To comply with the FCC RF exposure compliance
requirements, no change to the antenna or the device is
permitted. Any change to the antenna or the device could
result in the device exceeding the RF exposure
requirements and void user's authority to operate the
device.
