VH-110 WIRELESS SYSTEM
The VH-110 true diversity VH Series wireless system is a high quality audio product that has built
in noise reduction and utilizes the true diversity reception technique. True diversity receivers
contain two completely independent receivers tuned to the same frequency within a single
chasis. An internal processor compares the signal strengths at the output of each receiver and
determines which receiver has the clearest and strongest signal, and then that signal is than
directed to audio output. This is an automatic function that can be monitored by watching the A-B
diversity indicators on the front panel of the receiver.
Four different models are available and all operate on a VHF high band frequency between
174.60 MHZ to 204.60 MHZ.
THE MODELS AVAILABLE ARE:
VH-110M - which comes equipped with a hand held microphone transmitter.
VH-110L - which comes equipped with a belt pack and lavalier transmitter.
VH-110H - which comes equipped with a belt pack and a headset transmitter.
ALL MODELS ARE AVAILABLE IN SIX DIFFERENT FREQUENCIES:

RECEIVER OPERATION
Note: Effective range between the microphone and receiver is up to 250 feet.
1. Remove all packing materials. Save the box and packing material to transport the unit, and in
case the unit ever requires service.
2. Plug the AC adaptor into the rear of the receiver where the jack is labeled DC 12V. Then plug
the adaptor into an appropriate AC outlet. Switch the power to the ON position. Note: The
adaptor is available in 120V AC or 230V AC.
3. Extend the antennas fully and point them toward the direction you will be speaking from.
4. Insert the 1/4" phone cable into the jack labeled AUDIO OUT on the rear of the receiver, and
connect the other end of the cable to your amp, effects or mixer mic jack.
5. Adjust the volume using the level control on the front panel.
6. To adjust the squelch, place the small plastic tool (included with the unit) in the hole marked
SQUELCH at the back of the unit, and slowly turn the tool to adjust the output level to just
above the level of background noise. Setting the squelch too high will reduce the range of the
system. Setting the squelch too low will increase the level of unwanted noise.
HAND HELD TRANSMITTER FEATURES
• High sensitivity cardiod capsule for professional use
• Special noise absorption parts inside the barrels eliminating switch shock and handling noise
• Frequency with quartz locked control
CAUTIONS
1. Do not drop the microphone onto a hard surface.
2. Do not strike the microphone head front with fist or fingers, and do not blow strongly into the
microphone head front.
3. Do not use the microphone in areas of high humidity and/or high temperature as this could
lead to damage of the microphone.
HAND HELD TRANSMITTER OPERATION
1. Open the battery holder by turning it counterclockwise. Insert a 9V battery into the battery
holder according to the polarity indication marked on the battery housing. Close the battery
holder.
2. Push the power switch to the ON position. The BATT indicator should flash once briefly as you
turn on the mic indicating that the mic has sufficient power. If the BATT stays on, it indicates
that the battery has insufficient power and should be changed. If the BATT does not light at all
and the mic does not work, it indicates that the battery is dead , and you should change the
battery. If the microphone is not going to be used for any length of time, push the power
switch to OFF and remove the battery. Do not switch the mic on and off rapidly, because you
won't get a true indication from the BATT indicator.
LAVALIER BELT PACK TRANSMITTER FEATURES
• Heavy duty strain relief
• Foam wind screen
• Tie clip
LAVALIER BELT PACK TRANSMITTER OPERATION
1. Open the battery door by sliding towards the arrow. Insert a 9V battery into the battery holder
according to the polarity indication marked on the battery housing. Close the battery door.
2. Push the power switch to the ON position. The LOW BATT indicator should flash once as the
switch passes MUTE indicating that the mic has sufficient power. If the LOW BATT stays on,
it indicates that the battery has insufficient power and should be changed. If the LOW BATT
does not light at all, it indicates that the battery is either dead or not positioned correctly, and
you should correct the positioning or change the battery. If the transmitter is not going to be
used for any length of time, push the power switch to OFF and remove the battery.
3. The lavalier mic clip should be placed as high as possible in a vertical line with your mouth.
