Operating Instructions

1. Antenna Installation

2. Rear Antenna Installation: Attach supplied antenna to the antenna connector. Ensure both the antenna and the transmitter have the same frequency band for optimal transmitting efficiency.

3. Install an optional FB-71 rear-to-front rackmount kit with cable. Attach supplied antenna to the front for improved optimal transmitting efficiency.

4. Power
   Connect the supplied 12-15VDC / 1A power supply & cable to the DC Input Jack.Get the cable through the cable hole to prevent accidental disconnection.

5. Power On
   Press the Power Button Oto the ON position. The OLEO screen backlight lightens and displays various parameters.

6. Analog Audio Input and Output Connection
   In stereo mode, the stereo input signals with XLR plugs or the mixed mono signal with a 6.3 0 phone plug by plugging into AF IN XLR Combo«,. The LOOP OUT 41) L and R output sockets are possible to transmit the audio signals from one transmitter daisy chaining the signals to other transmitters in balanced transmission mode.

7. Input Signals Level Indicator Setting
   If the audio input signal is too low, it will result in a high noise floor and worse sound quality; if the audio input signal is too high, it will result in distortion.
   Recommended setting methods as below:

8.  Press the UR-LEVEL Buttons 0 to set the LEVEL Meter to 0. Activate the source audio output and set the output level to the maximum.

9. Watch the color of the UR Input Quality Indicator 0 and adjust the proper gain by the UR-LEVEL Buttons 0 until the green indicator (OK) lights on.

10. Orange indicator (LOW) indicates the audio input signal or gain is set too low.

11. Red indicator (PEK) indicates the audio input signal or gain is set too high.

12. When the audio input signal continues to be too high, the screen will display
    “CLIP !” warning message to denote the sound distortion. It is necessary to check if the input signal level is set too high to avoid distortion.

13. During the setting process, plug the headphone into the monitor jack on the transmitter, and watch the color of OLEO indicators to adjust the proper input level, and then turn on the receiver to monitor the sound.

14. Headphone Monitoring

15. Insert a 6.3 0 or 3.5 0 headphone into the Headphone Jacks@G , and adjust Volume Control 8 to the adequate volume.
    Warning: Permanent noise-induced hearing damage or loss may occur on prolonged exposure to loud sounds wearing earphones or headphones.

Cautions & Recommendations

1. Do not use the same frequency bands when mixing MIPRO IEM and MIPRO wireless microphone systems to avoid potential interferences.

2. Do use 500 coaxial cable to connect the transmitter to the external antenna. RG-58 or 3D cable should not exceed 2 meters. Recommend to use 5D-FB or 8D-FB cable for an even longer length to decrease the cable loss of
   2.4 GHz transmission.

3. If possible, maintain line-of-sight between transmitter and receivers for optimal reception quality during outdoor or indoor performances. Indoor reception quality tends to degrade due to obstacles and objects absorbing radio waves making the reception distance shorter compared with outdoor performances.

4. The power supply voltage should not be less than 12VDC and not higher than 15VDC. Ensure at least 1A or more output current. Insufficient voltage causes operating instability or malfunction; exceeding voltage causes reduced product life cycle and possible short or damaging circuits.

5. Ml-24T/Ml-24TD stationary transmitter should pair with the Ml-24R bodypack receiver.

Notes

1. Refer to the actual product in the event of product discrepancy.
2. Carrier frequency range, RF power and maximum deviation range comply with the regulations of different countries.
