The rack mountable kits are pre-drilled with 4 opening holes to be fitted on an EIA
standard 19-inch rack case. (Figure 7)
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 8)

Receiver Operating Tips

Prior to powering on the receiver, ensure all transmitters are turned off and the
mixer's volume control is set to minimum.
Normally, the RF meter level illuminates fully 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 will also illuminate based on signal level.
If the meter or indicator does not indicate or there is no audio output, the system
may not be set up properly. Re-check that the transmitter has fresh batteries and is
turned on and the receiver and transmitter are on the same frequency. If not, the
transmitter will need to be set up via the ACT sync function.
The microphone output level in normal use should be adjusted at the amplifier or
mixer. There is no need to adjust output levels at the receiver itself once initial
setup is completed.
The antenna inputs provide an 8-volt DC bias and are designed to work with MIPRO
antenna boosters and active antennas. If the connecting cable is longer than 10
metres (approx. 30'), it is advisable to install an antenna booster to ensure optimum
reception.
Antenna dividers and receivers must match the same frequency band (i.e. both
should be marked 6B, 6C etc.)
