Connection Method of Balanced Output:
!
When receiver and mixer/amplifier is under long distance. or the connectors of
receiver/mixer/amplifier are “XLR” types. Using audio output cables with “XLR” or
“Cannon” type connectors, connect one end to the balanced output jacks , of the
receiver, and the other end to the “MIC IN” input jack of the mixer or amplifier, as
shown in Figure 1. (The configuration of the 3-pin connector is as shown in Figure
2.)
Electrical Guitar Output:
!
Using audio output cable attached with “PHONE PLUG” type, plug one end from the
balanced output jack of a receiver, and the other end to the input jack of a guitar
amplifier. Switch the Level Switch “LINE” position.
Antenna Inputs:
!
The antenna inputs provide 8-volt DC biased and are designed to work with MIPRO
antenna boosters. If the connecting cable is longer than 10 meters (approx. 30'), it
is advisable to install an antenna booster to ensure optimal reception.
Receiver Operating Tips
Prior to powering on the receiver, ensure all transmitters are turned off and the
mixer's volume control is set to a minimized setting.
Normally, the RF meter level glows when a transmitter is powered on to indicate the
receiver is ready for operation. Once an audio signal is received from the
transmitter, the AF (audio) meter level glows based on signal strength. If the meter
or indicator does not glow or there is no audio output, the system may not be set
up properly. Re-check that the transmitter is turned on and the receiver and
transmitter are on the same frequency (if not, the transmitter will need to be reset
via the ACT function).
The microphone output level needs to be adjusted at the amplifier or mixer. There
is no need to adjust output levels at the receiver itself.
Antenna dividers and receivers must be from the same frequency band.

Rackmount Installation for Receivers
Receiver Rack-Mount Kits
Half-Rack Unit Receiver
!
Install the optional FB-71 rackmount kit & fasten with screws on both sides. (Figure 3)
1-Rack Unit Receiver
!
Install the optional FB-72 rackmount kit & fasten with screws on both sides. (Figure

!
!
The rack mountable kits are pre-drilled with 4 opening holes to be fitted on an EIA
standard 19-inch rack case. (Figure 5)
For ideal reception and performance, install the receiver at least 1 meter (3 feet)
above the ground and away from EMI / RFI “noise” sources. In addition, place the
transmitter/microphone at least 1 meter (3 feet) away from the receiving antenna,
as shown. (Figure 6)
