Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
- Apparatus should not be exposed to dripping or splashing and no objects filled with liquids, should be placed on the apparatus.
- Use only with the battery which specified by manufacturer.
- The power supply cord set is to be the main disconnected device.
- Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
WARNING

Receiver Installation
-
Antenna Connection:
Connect an antenna to each of the antenna connectors 0 on the rear panel. Fig. 2. Antenna connectors provide an 8-volt DC bias to work with MIPRO antenna boosters. If the antenna cable is longer than 10 meters, it is advisable to install an antenna booster to ensure optimal reception. -
Power Connection:
Connect the power supply to the receiver DC input10 and plug it into an AC power source. Fig. 2. -
Audio Output Connection:
-
(A) When connecting the audio output to the MIC IN jack of the mixer or amplifier, switch output level switch e to O dB. When connecting to LINE IN jack, set
output level switch to +16 dB when using balanced XLR connector or set output level switch to +10 dB when using unbalanced (6.3 0) connector. When connecting to an amplifier with non-standard gain, set output level switch to -6 dB when there is distortion at the maximum output level. -
(B) Output for electric guitar/bass: Use a 6.3 0 phone cable. One end to receiver’s unbalanced output jack and the other end to guitar/bass amplifier’s input jack. Switch the output level to the “+10 dB” position.
-
(C) Use an XLR cable to connect the receiver audio output jacks 6)’11) to a mixer or an amplifier’s MIC IN jack.
-
(D) Use a PHONE cable to connect the unbalanced phone jacks 12 16 18 to a mixer or an amplifier’s LINE IN jack.
-
(E) To mix the multiple channel outputs, connect to the mixed output jacks 11)or 12 and switch the output switch 14 to the MIX position. Fig. 3
-
(F) See Fig. 4 for a 3-pin XLR connector wiring diagram.
-
Receiver Operation
- Before turning on the receiver, ensure all transmitters are powered off and the mixer’s volume control is set to a minimized setting. When the receiver is turned on and the LED screen glows, it is working normally.
- RF meter level ® glows when a transmitter is powered on. Once the audio signal is received from the transmitter, the AF level meter 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.
- (For ACT-311/ACT-312 only} The microphone volume is adjusted at the amplifier or mixer. No adjustment is needed at the receiver.
Rackmount Installation for Receivers
- Single half-rack or single 1-rack receiver: Install the optional rack mount kit and fasten with screws on both sides. Fig. 5
- Receiver Rack-Mount Kits (optional). Fig. 6
- Fasten the receivers on an EIA standard 19-inch rack case. Fig. 7
- For ideal reception range, install the receiver at least 1 meter above the ground and away from EMI / RFI “noise” sources. Besides, place the transmitter at least 1 meter away from the receiving antenna, as shown in Fig. 8.
- Proper install of antennas affects the operating efficiency of the receiver. The main principle is to minimize the distance between the receiving antenna and transmitter for best reception quality.
- Use MIPRO supplied antennas to ensure proper receiver sensitivity.
- The antenna connector provides an 8V DC bias output. Short circuits should be avoided.
- Install MIPRO directional antennas and boosters if extended reception distance is required.
- Use the antenna distributor in the multiple channel wireless systems to simplify the antenna installation and improve receiving efficiency.
- For multiple wireless systems operations, it is recommended to select MIPRO’s factory preset interference-free channels within the same group to ensure optimum performance.
