Receiver Installation. Fig. 2

1. Connect an antenna to each antenna connector(i)on the rear panel.
2.  Power Connection: Connect the power supply to the DC input jackand 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 an XLR Male to XLR Male microphone cable. Fig. 2
   •  3-pin XLR output wiring diagram,as Fig. 3 shows.
   • The mixed audio signals of CH1 ~ CH4 from a receiver’s balanced output XLR connector W can be connected to the balanced input jack of a mixer or amplifier. Another way is to connect from a receiver’s unbalanced output 6.3 mm connector GI to the LINE IN jack of a mixer or amplifier.
   •  Use an XLR to 6.3 mm jack cable to plug into the LINE IN jack of a mixer or amplifier. Switch the Volume Level Switch Cl) to +10dB.
   • Unbalanced Output Connection: When a receiver and a mixer/amplifier is under short distance or the connectors of receiver/mixer/amplifier are “PHONE” type, use a 6.3 mm jack to 6.3 mm jack audio cable to connect from the unbalanced output jack of the receiver to the LINE IN jack of a mixer/amplifier.
   • When the audio output is connected to the MIC IN jack of a mixer or amplifier, switch the Volume Switch 0 at 0dB. When connected to LINE IN, switch to + 16dB for a balanced output XLR connector and switch to +10dB for an unbalanced output 6.3 mm connector. Switch to -6dB if the maximum output volume of an amplifier is distorted.
4. Antenna Connection: antenna connectors provide 8-volt DC bias for 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 the transmitter is powered on. Once the audio signal is received from the transmitter, the AF audio meter level glows in accord with signal strength. The system is abnormal if the 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 is needed at the receiver.

Tips for Receiver Installation

1.  Receivers can be installed on an EIA standard 19-inch rack case. Fig. 4
2. Rackmount kit (optional). Fig. 5
3.  For improving reception, an optional rear-to-front antenna cable installation through rackmount screw holes is highly recommended. Fig. 6
4.  For improving the reception range, install the receiver at least 1 meter above the ground and away from EMI / RFI “noise” sources. Also, place the transmitter at least 1 meter away from the receiving antenna. Fig. 7
5.  Proper installation of antennas enhances the operating efficiency of the receiver. The most important rule is to minimize the distance between the receiving antenna and transmitter for the best reception quality.
6. Use MIPRO’s antennas to ensure proper receiving sensitivity.
7. The antenna connector provides 8V DC bias output. Short circuits should be avoided.
8. Install MIPRO’s directional antennas and boosters if an 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:
    •  Remove top and bottom screws,as Fig. 8.
    •  Screw top, bottom and back plates to joint two receivers, as Fig. 9
    •  Rackmount with an optional rack-mount kit, as Fig. 10.
