Setup And Connections - JB Systems WBS-20 Manual De Instrucciones

ENGLISH
INSTALLING THE RECEIVER:
Standalone: You can use the receiv-
er standalone: just put both antennas
in vertical position and connect the
receiver as described in the chapter
"connections".
In a 19" rack: you can install one or
two receivers in a 19" rack, using an
optional "RP-WMIC" adapter:
1. Install 2 pieces ear short racks on
both side sides of receiver.
2. Install the receiver inside the 19"
metal rack adapter by screwing
the ear short racks.

SETUP AND CONNECTIONS

! Some important notes before we start !
 One receiver can only be used with one transmitter (handheld mic / belt pack). Using 2 or more transmit-
ters simultaneously with the same receiver is impossible: this will result in a lot of interference and trouble!
 Receiver and transmitter should always use the same channel setting (frequency)!
 The distance between receiver and transmitter should at least be 1 meter.
 To minimize interferences install the receiver away from big metal surfaces/objects, TV and other wireless
appliances.
 Try to minimize the number of obstructions (thick concrete walls, big metal objects, ...) in the path between
the transmitter and receiver.
 Up to 4 or 5 transmitters can be used simultaneously on condition that each has its own receiver!
RECEIVER – AUDIO CONNECTIONS
First determine which audio inputs are available on your mixer, next decide how to connect the receiver:
 To a balanced MIC-input of the audio mixer: close
the gain of the mixer input and set the mic/line switch
on the receiver (7) to MIC. Use an XLR/XLR cable to
connect the receiver "XLR-output (5)". Switch the
transmitter (hand mic/belt pack) on and bring the in-
put gain of the mixer slowly up.
 To a balanced LINE-input of the audio mixer:
close the gain of the mixer input and set the mic/line
switch on the receiver (7) to LINE. Use an XLR/XLR
cable to connect the receiver "XLR-output (5)".
Switch the transmitter (hand mic/belt pack) on and
bring the input gain of the mixer slowly up.
 To an unbalanced MIC-input of the audio mixer:
close the gain of the mixer input and set the mic/line
switch on the receiver (7) to MIC. Use the supplied
JACK/JACK cable to connect the receiver "JACK-
output (6)". Switch the transmitter (hand mic/belt
pack) on and bring the input gain of the mixer slowly
up.
 To an unbalanced LINE-input of the audio mixer
or hifi stereo set: close the gain of the mixer input and set the mic/line switch on the receiver (7) to LINE.
Use the supplied JACK/JACK cable to connect the receiver "JACK-output (6)". Switch the transmitter
(hand mic/belt pack) on and bring the input gain of the mixer slowly up.
NOTE: never use the balanced and unbalanced outputs together, this will results in signal loss and in-
creased noise.

WIRELESS HAND MIC – SETUP
 Switch the Receiver on and select a channel.
 Open the battery compartment and insert two AA batteries (alkaline or fully charged Ni-MH type).
 Select exactly the same frequency channel (5) as on the receiver.
 Press the power switch (3) for some seconds: one of the diversity LEDs (4) on the receiver should be lit to
indicate that the RF-signal of the transmitter is captured.
 Speak through the mic: the AF indicator (3) will flash to the rhythm of your voice.
 While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
BELT PACK – SETUP
 Switch the Receiver on and select a channel.
 Open the battery compartment and insert two AA batteries (alkaline or fully charged Ni-MH type).
 Select exactly the same frequency channel (6) as on the receiver.
 Connect the lavalier microphone or optional headset mic and put the MIC/LINE switch (4) on the belt pack
to MIC.
 Alternatively you can also connect a line audio signal (ex. Guitar), in that case you should put the
MIC/LINE switch (4) on the belt pack to LINE.
 Press the power switch (2) for some seconds: one of the diversity LEDs (4) on the receiver should be lit to
indicate that the RF-signal of the transmitter is captured.
 Speak through the mic: the AF indicator (3) will flash to the rhythm of your voice.
 If needed, you can still fine-tune the audio level with the gain knob (7).
 While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
SEVERAL SETS WORKING TOGETHER – SETUP NOTES
Even if the transmitters and receiver have 16 channels, you cannot use 16 wireless systems together: de-
pending on the situation you will be able to use maximum 4 or 5 sets together.
While setting up more than one system, you should choose different channels for each set. It's important that
you never choose consecutive channels. Instead try to divide the channels evenly over the 16 possibilities:
Example1: mic1 = CH1 ~ mic2 = CH3 ~ mic3 = CH5 ~ mic4 = CH7
Example2: mic1 = CH1 ~ mic2 = CH3 ~ mic3 = CH14 ~ mic4 = CH16
Example3: mic1 = CH9 ~ mic2 = CH11 ~ mic3 = CH14 ~ mic4 = CH16
Example4: mic1 = CH1 ~ mic2 = CH5 ~ mic3 = CH11 ~ mic4 = CH16
 First setup one system and leave it switched on. (see above for more information)
 Setup the second system and check if it interferes with the first one (unwanted buzz noises etc.). In case of
interferences, select another channel for your 2
the set switched on.
rd
 For the 3
set, just repeat what you did for set2 until all 3 sets can work together.
TROUBLESHOOTING
Problem Solution
No sound  Check the power supply of the microphone and receiver.
 Check that the transmitter and receiver are tuned to the same channel (frequency).
 Check if the hi-fi appliance or audio mixer is switched on and the receiver output is
connected to audio desired input. Mixer: is the gain open?
 Check if the transmitter is too far away from the receiver or SQUELCH control is set
too high.
 Check if the receiver is located near a large metal object or if there are large obstruc-
tions (ex. large metal object or thick wall) between transmitter and receiver.
Sound interference  Check the antenna location.
 When using 2 or more microphone sets simultaneously, make sure that the selected
channels don't interfere: select another channel pair on one of the sets.
 Check whether the interference comes from other wireless microphones, TV, radio,
PC, etc.
Distortion  Check if the receiver volume level is set too high or too low.
 Check if the mic/line switch and gain volume on the belt pack are correct.
 Check if the interference comes from other wireless microphones, TV, radio, PC, etc.
