Rack Installation

The US-903DCPRO / 5 is provided as a table top unit
or for installation into a rack for units with a width
of 482 mm (19") For rack installation, unscrew the
four feet and screw the two supplied mounting
brackets (12) with two screws each to the front at
the left and right sides of the housing

Connection
1) Insert the two supplied antennas (3) to the BNC
antenna jacks ANT 1 and ANT 2 (13) and place
them in a vertical position
2) For connection to the subsequent unit (e g
mixer, amplifier), the following audio outputs
can be used:
AF OUTPUT BAL. (14)
balanced XLR outputs for the output signals of
the receiver units CH 1 and CH 2 for connection
to a balanced microphone input each
AF MIXED OUTPUT UNBAL. (16)
unbalanced 6 3 mm output for the master signal
of the two receiver units for connection to a line
input (a matching connection cable is supplied)
3) Connect the supplied power supply unit to the
jack (17) for the power supply and to a mains
socket (230 V/ 50 Hz)

Operation
Switch on the receiver with the POWER switch
(11) The display (10) shows the adjusted group
and the adjusted transmission channel (c) for the
two receiver units If a receiver unit does not receive
a radio signal of sufficient power or if the mute
function of the wireless microphone MH-8800G / 5
is switched on, the receiver unit will be muted and
the display will show MUTE (e)
Make the following adjustments separately for
each receiver unit
1) Before switching on the transmitter, set the re-
ceiver to a transmission channel which is not
used and which is free from interference, see
chapter 6 1 Via the audio unit connected to
the output, no interference or signals of other
transmissions must be audible and the reception
bar graph RF (a) must not indicate any signal
2) Switch on the wireless microphone MH-8800G / 5
or the pocket transmitter PT-920BG / 5 and set
it to the group and the transmission channel
adjusted on the receiver: see instruction manual
of the microphone or the transmitter
If the transmitter and the receiver are set
to the same channel and if a radio signal of
sufficient power is received, muting will be de-
activated [indication MUTE (e) is extinguished]
One of the indications
to indicate which of the two antennas receives
the more powerful radio signal The bar graph
RF (a) shows the quality of the signal received:
the more segments of the bar graph light up,
the better the reception
If the reception is poor or if there is interference,
check if
a the reception is better on a different trans-
mission channel
b the batteries of the transmitter are not suffi-
ciently charged (see battery status indication
on the transmitter)
c the distance between the transmitter and
the receiver is too long
d the reception is disturbed by objects in the
transmission path
The transmitter and the receiver should have
a minimum distance of 50 cm to metal ob-
jects and any sources of interference, e g
motors or fluorescent tubes
e the reception can be improved by turning
the antennas
f the squelch adjusted by means of the con-
trol SQUELCH (15) is too high (see operating
step 5)
