NOTE
• Before setting up your Perception wireless, check that the transmitter and receiver are
tuned to the same frequency. The wireless connection will not work if the receiver and
transmitter are tuned to different frequencies.
• Never use both outputs (BALANCED and UNBALANCED) at the same time. This can cause
loss of signal and increased noise.
• Set up the receiver as a free-standing unit.
• Reflections off metal parts, walls, ceilings, etc. or the shadow effects of musicians and
other people may weaken or cancel the direct transmitter signal.
For best results, set up the receiver as follows:
1) Place the receiver near the performance area (stage). Make sure, though, that the
transmitter will never be any closer to the receiver than 10 ft (3 m). Optimum separation
is 16 ft (5 m).
2) Check that you can see the receiver from where you will be using the transmitter.
3) Place the receiver at least 5 ft. (1.5 m) away from any large metal objects, walls,
scaffolding, ceilings, etc.

Setting up
Connecting an instrument
1) Remove the battery compartment cover.
2) Plug the jack plug on the MKG L guitar cable into the output jack of your instrument and
the mini XLR connector on the guitar cable into the audio input socket of the bodypack
transmitter.
3) Turn the bodypack transmitter on by setting the on/off switch to "ON".
4) Set the SQUELCH control on the receiver to minimum and switch the receiver on.
5) Play your instrument.
6) Use the screwdriver integrated in the battery compartment cover to set the GAIN control
to a position where the CLIP LED on the receiver will flash occasionally.
7) Replace the battery compartment cover on the transmitter.
Before the soundcheck
1)
Move the transmitter around the area where you will use the system to check the area for
"dead spots", i.e. places where the field strength seems to drop and reception
deteriorates.
If you find any dead spots, try to eliminate them by repositioning the receiver. If this does
not help, avoid the dead spots.
2) If the RF OK LED on the receiver goes out, this means no signal is being received or the
squelch is active.
Switch the transmitter on, move closer to the receiver or adjust the squelch level to the
point where the green RF OK LED lights up.
3) If interference noise occurs, adjust the squelch level until the interference noise goes
away.
Do not set the squelch level higher than necessary. The higher the squelch level, the lower the
sensitivity of the receiver and hence the smaller the range between transmitter and receiver.

Microphone technique
4 Microphone technique
HT 45 handheld transmitter
A handheld vocal microphone provides many ways of shaping the sound of your voice as it is
heard over the sound system.
The following sections contain useful hints on how to use your HT 45 handheld transmitter for
best results.
Working distance and proximity effect
Basically, your voice will sound bigger and mellower, the closer you hold the microphone to
your lips. Moving away from the microphone will produce a more reverberant, more distant
sound as the microphone will pick more of the room’s reverberation.
You can use this effect to make your voice sound aggressive, neutral, sensual, etc. simply by
altering your distance from the microphone.
The proximity effect is a powerful increase in low frequency response that occurs when a
sound source is close to a microphone (less than 2 inches / 5 cm). It gives more "body" to
your voice and an intimate, bass-heavy sound.
Angle of incidence
Sing to one side of the microphone or above and across the top of the microphone. This
provides a well-balanced, natural sound.
If you sing directly into the microphone, it will not only pick up excessive breath noise but also
overemphasise "s", "sh", "tch", "p", and "t" sounds.
Feedback
Feedback occurs when part of the sound projected by the loudspeakers is picked up by a
microphone, amplified and fed back to the speakers. Above a certain volume (the feedback
threshold) this process becomes a vicious circle, making the sound system howl and screech.
The only solution is to turn down the volume.
To reduce the danger of this happening, the microphone of the HT 45 has a cardioid pickup
pattern.
This means that the microphone is most sensitive to sounds arriving from in front of it (your
voice), while picking up hardly any sound arriving from the sides or rear (from monitor
speakers for instance).
To maximize gain before feedback, place the PA speakers in front of the microphones (along
the front edge of the stage).
If you use monitor speakers, be sure never to point any microphone directly at the monitors or
at the PA speakers.
Feedback may also be triggered by resonances (due to the room acoustics), particularly in the
low frequency range, and thus indirectly by the proximity effect. In this case, it is often enough
to move away from the microphone a little to stop the feedback.
Backing vocals
1) Never let more than two people share a microphone.
2) Backing vocalists should not sing at more than 35° to the microphone axis.
The microphone is very insensitive to sounds arriving from the side. If the two vocalists
were to try and sing into the microphone at an angle of more than 35° to the microphone
axis, you would have to turn up the level of the microphone channel high enough to cause
a feedback problem.
Perception wireless
29
Microphone technique
PT 45 bodypack transmitter
CK 55 L lavalier microphone
Fix the microphone to the supplied lavalier clip or to the optional H 41/1 tiepin.
1)
Clip the microphone onto the speaker's clothing, as close as possible to his or her
mouth.
The closer the microphone is to the speaker's mouth, the less danger there is of feedback.
NOTE
2)
Make sure to aim the microphone towards the user's mouth.
C 544 L headset microphone
Putting on the microphone
1) Put the microphone on.
2) Bend the gooseneck so that the microphone sits to one side in front of the corner of your
mouth.
NOTE
• If you hear excessive pop noise ("p" and "t" sounds are overemphasised unnaturally),
move the microphone capsule further away from your mouth (back or down).
• If the microphone sounds "thin" or flat, move the microphone capsule closer to your
mouth.
• Find the optimum position during the soundcheck.
Windshield
If (for instance,on an open-air stage) excessive wind or pop noise becomes audible, attach the
supplied foam windshield to the microphone.
1)
2)
Slide the windshield onto the microphone capsule.
Pull the windshield over the outer end of the microphone capsule.
Moisture shield
A special moisture shield on the microphone capsule makes it harder for moisture and
makeup to penetrate into the microphone.
This prevents the microphone apertures from being clogged by perspiration or makeup, which
would make the sound dull and reduce the sensitivity of the microphone. Therefore, you
should never remove the moisture shield from the microphone.
The C 544 L headset microphone includes a replacement moisture shield in case the first one
gets damaged or lost.
