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.)
