If liquids are spilled on any component, stop using t e set immediately, allow unit to dry out and ave it c ecked

by qualified personnel before furt er use.

Avoid impact or eavy vibration to any of t e components. Dropping a microp one can cause capsule failure.

No user serviceable parts inside transmitter or receiver - refer servicing to qualified service personnel.

Safety

• Ensure t at t e correct adapter is used wit adequate current rating and t at t e mains voltage is as

stated on t e adapter.

• Avoid ingress of water or particles into t e transmitters or receiver

• Use alkaline or NiMH batteries in t e transmitters and remove if t ey are unused for long periods.

• Observe t e correct polarity w en replacing batteries

Placeme t

• Keep all components out of direct sunlig t and away from eat sources.

• Do not place eavy objects on top of t e receiver or transmitters

• If rack-mounting, use t e rack ears provided and do not place eavy equipment above t e receiver.

• Keep t e transmitters and receiver away from damp or dusty environments.

Clea i g

Setti g Up

Insert t e supplied AA batteries into t e transmitter by carefully unscrewing t e base of t e

and eld or opening t e flap of t e bodypack to reveal t e battery compartment. Insert t e batteries

(ensuring t at + and - are t e correct way round for eac cell) and carefully replace t e cover.

For neckband or lavalier microp ones, connect t e microp one lead into t e bodypack, ensuring it is securely

pus ed into t e socket.

T e receiver antenna may be connected directly to t e BNC connector on t e rear panel or

alternatively front-mounted onto rack ears (see below)

If t e receiver is to be rack-mounted, place t e supplied rack ears against eac side of t e receiver

and fix securely wit 2 screws in eac . T ese rack ears ave a ole for front-mounting t e antenna

and a BNC extension lead for fixing into t e ole. T is s ould be connected to t e BNC on t e rear

panel, creating a front socket for t e antenna to connect onto.

A c oice of unbalanced 6.3mm jack or balanced XLR output is available on t e rear panel of t e

receiver. Connect t e jack or XLR (optional) lead to t e relevant output connector, turn down t e

volume of any equipment (mixer, amplifier etc.) t at t e signal will be fed into and t en connect t e

jack or XLR to t e equipment.

Position t e receiver wit in t e best available line of sig t to t e transmitters and connect t e DC

jack of t e supplied power adaptor to t e receiver and t e plug top to t e mains outlet.

Operatio

Turn microp one levels down on t e receiver and switc on power on t e front panel of t e receiver.

Warning! - take care not to point microp ones towards speakers – t is can cause damaging feedback

(loud w istle or owling noise) – try to point microp ones away from t e speaker cabinets.

For t e and eld version, move t e switc on t e and eld transmitter upward to switc it on and

t e LCD display s ould lig t for a few seconds, s owing t e carrier frequency and battery status.

For t e bodypack transmitter, press and old t e front on/off button until t e display lig ts up for a

few seconds, ensuring t at t e Mute switc is off. T e display will s ow t e current carrier frequency

and battery status. T e transmitter frequency s ould matc t e frequency on t e receiver. If not,

see “Tuning” below.

Gradually increase t e microp one level on t e receiver, t en increase t e volume on t e mixer or

amplifier until t e sound from eac microp one can be eard t roug t e equipment.

By Pressing t e Mode button twice on t e belt pack, you can set t e input sensitivity of t e transmitter. T is

means you can connect devices wit a different output level to t e supplied microp one, or turn t e level down

if t e device is overloading.

After pressing t e button twice you will see t e left and bars flas on t e screen. Using t e set button you can

select Line, Low, Medium, or Hig sensitivity. Line being t e least sensitive.

Tu i g

T e carrier frequency may be selected on t e receiver unit by pressing t e SET button, w ic

causes t e GROUP label to flas in t e display. Buttons 16 & 17can be used to select t e

Group from 1 to 7. Pressing t e SET button again causes t e CHANNEL label to flas . T e c annel

can be selected wit in a group using buttons 16 & 17.

Groups 1 to 6 ave between 3 and 5 preset c annels, w ilst Group 7 allows access to all 81 possible

frequencies. Depending upon any ot er radio signals in t e vicinity of t e operating environment,

one particular Group may offer a better c annel spacing t an anot er and t is s ould be determined

by experimentation. If a particular group of frequencies results in poor reception or interference, try

WMU-116 Radio Micropho e

anot er or use Group 7 to manually select carrier frequencies in 25kHz steps. T e groups ave preset c annel

spacing t at work on t e licence free band. Up to four microp ones can be used toget er, use t e same group

and select different frequencies for eac microp one set.

Once a c annel is selected, press SET to accept t e c annel and press SET again to transmit t e IR

sync signal (animated lines will s ow next to IR in t e display). Hold t e IR detector on t e and eld

microp one or bodypack transmitter up to t e IR sender on t e main unit to sync t e carrier frequency to t e

transmitter. T e transmitter must be switc ed on for t is to work and will flas briefly w en t e frequency is

sync ronised and a padlock sign will appear on t e receiver display. T e two displays will s ow t e same

frequency at t is point.

I Use

Switc ing on t e transmitter will send a radio carrier frequency to t e receiver and also send a

pilot tone frequency, w ic is not audible but is used by t e receiver to open t e audio c annel. T is

system elps to avoid any spurious radio frequencies interfering wit t e wireless microp one signal.

W en t e transmitter’s RF signal is recognized by t e receiver, an RF meter will s ow t e carrier

signal strengt in t e LCD display, t is is to t e left of t e display. If t e transmitter is out of range t e display

bars will dissapear. Likewise, speaking into t e microp one will send audio over t is carrier and an AF volume

meter will s ow t e audio level in t e LCD display.

For t e neckband or lavalier microp one, t ere is also a mute switc on t e top of t e bodypack,

w ic can be used to temporarily cut t e microp one output w ilst maintaining t e carrier

frequency. T is may be useful to silence t e mic w ilst moving across t e front of speakers or as a

standby setting.

If t e wireless system is to be out of use for longer t an a few minutes, it is preferable to switc t e

transmitter off, w ic deactivates t e radio carrier signal and powers down t e transmitter.

Be sure to turn down t e volume of t e mixer or amplifier and t en switc off t e receiver.

Unplug signal leads from t e receiver and mixer or amplifier w en moving or packing away.

If t e system is not to be used for long periods of time, remove t e batteries from t e transmitters

and unplug t e power adapter from t e receiver and t e mains outlet.

Folding away or removing t e antennas can also elp avoid damage w en t e system is not in use.
