UHF Diversity Wireless Receiver
MAINS ADAPTER & DC JACK (rear panel) -
The Ashdown Freebass UHF diversity receiver
is supplied with a mains adapter to power
the unit. This plugs into the DC jack on the
rear panel of the unit. Use only the mains
adapter that is supplied with the system.
Using any other mains adapter may result in
damage to your system.
POWER BUTTON - Turn the receiver ON by
pressing the POWER button on right hand
side of the front panel. This will light up blue,
the UP, DOWN & SET buttons will light up
green, the Channel Number display will
illuminate showing the currently selected
UHF Frequency Channel and the Audio VU
meter will be back lit.
ANTENNA - The receiver has two antennas
each feeding a separate wireless input stage
for true diversity operation. Before using the
system raise these antennas to allow for
optimum reception.
UP, DOWN & SET BUTTONS - To select the
Channel Number use the UP and DOWN
buttons to reach the desired number as shown
on the CH display and then press the SET
button to select it. The selected Channel
Number will be remembered next time the unit
is powered up to be used. For details of the
specific frequency of each Channel Number see
the chart at the end of these instructions.
The same Channel Number must be used
on receiver and transmitter for the system
to operate.
RF DISPLAY - The RF LED display shows the
level of incoming UHF radio signal being
received from the Belt Pack Transmitter.
When all LEDs are illuminated it indicates you
have optimum signal reception, this is what
you need to try to achieve. If only a few LEDs
are illuminated the system may still function
but it shows you are in a poor reception
mode so try to improve this with antenna
positioning and reducing the distance
between transmitter and receiver.
VU METER - This indicates the level of
incoming audio signal. As long as the meter
indicates below 0dB then the signal will be
clean and undistorted. If the meter is
indicating in the RED region above 0dB then
the signal into the Belt Pack Transmitter will
have to be reduced to prevent overload of
the system and distortion occurring. This is
only ever likely to happen if you are using an
active bass with a very high signal output
level. In this case reduce the setting of the
instruments volume control to the optimum
level for the Freebass system.
VOLUME - This rotary control sets the level of
audio signal to the unbalanced Jack socket
and the Balanced XLR located on the rear
panel. The rear panel HI-MID-LOW slide
switch selects from 3 ranges of signal level to
the balanced XLR.
