Warning: Avoiding Hearing Damage –
Permanent noise-induced hearing loss may occur on prolonged exposure to loud sounds wearing earphones or headphones. We recommend you listen responsibly by limiting the amount of time that you use earphones or headphones at high volume.

• To prevent possible hearing damage, do not listen at high volume levels for long periods.

1. Connect an antenna to each antenna connector 0 on the rear panel.
2. Power Connection: Connect the power supply to the DC input jack? and plug the other end into an AC power source.
3. Audio Output Connection:
   • Each channel signal output can be connected to the mixer or amplifier’s MIC IN jack by using a cable with balanced XLR connector. Fig. 2
   • 3-pin XLR output wiring diagram, as Fig. 3 shows.
   • Using a cable with one end XLR plug, one end 6.3 0 phone plug, connects to LINE IN jack of a mixer or amplifier. Switch the Volume Level Switch® to +16dB.
   • When audio output is connected to MIC IN jack of a mixer or amplifier, switch the Volume Switch® at OdB. When connected to LINE IN, switch to +16dB. Switch to -6dB if the maximum output volume of an amplifier is distorted.
4. Antenna Connection: antenna connectors provide 8-volt DC bias to work with MIPRO antenna boosters. If the antenna cable is longer than 10 meters, it is recommended to add an antenna booster to ensure optimal reception.

Receiver Operation

1. Before turning on the receiver, ensure all transmitters are powered off and the mixer or amplifier’s volume control is minimized. When the receiver is turned on and the VFD screen glows, it is working normally.
2. RF meter level glows when transmitter is powered on. Once audio signal is received from the transmitter, the AF audio meter level glows in accord with signal strength. System is abnormal if RF indicator or AF meter does not glow, then adjustment or repair might be required.
3. The microphone volume is adjusted at the amplifier or mixer. No adjustment needed at the receiver.

Tips for Receiver Installation

1. Receivers can be installed on an EIA standard 19-inch rack case.
2. Rack mount kit (optional).
3. For improving reception, an optional rear-to-front antenna cable installation through rackmount screw holes is highly recommended.
4. For improving reception range, install the receiver at least 1 meter above the ground and away from EMI / RFI “noise” sources. In addition, place the transmitter at least 1 meter away from the receiving antenna.
5. Proper installation of antennas enhances the operating efficiency of receiver. The most important rule is to minimize the distance between the receiving antenna and transmitter for best reception quality.
6. Use MIPRO’s antennas to ensure proper receiving sensitivity.
7. Antenna connector provides 8V DC bias output. Short circuits should be avoided.
8. Install MIPRO’s directional antennas and boosters if extended reception distance is required.
9. Use the antenna distributor in the multiple channel wireless systems to simplify the antenna installation and improve receiving efficiency.
10. For multiple compatible systems operation, it is recommended to select MIPRO’s factory preset interference-free channels within the same group to ensure optimum performance.
11. Rackmount two units side-by-side: (optional)
    • Remove top and bottom screws, as .
    • Screw top, bottom and back plates to joint two receivers, as .
    • Rackmount with an optional rack-mount kit, as .

5. EQ will automatically be set to EQ-09 when interfaced with a PC computer. Receiver will transfer the 32 parameters to EQ-09 from PC computer.

PC ADDRESS Setting.

1. Receiver has ACT-BUS interface. Install MIPRO hardware and software for PC remote­ control and monitoring up to 64 MIPRO receiver channels simultaneously.
2. Address numbers need to be pre-programmed in advance from 01 – 64 before interfacing for network monitoring and control. However, to ensure networking is working properly, all address numbers need to be different from each other to avoid address conflicts.
