The SR 40 SINGLE/DUAL series includes two stationary receivers for use with all WMS 40 and Microtools Series trans-
mitters. They feature a half-rack case for mounting in a 19" rack.
The SR 40 SINGLE provides a single reception channel and operates on one fixed, quartz stabilized frequency in the
660 MHz to 865 MHz UHF carrier frequency range.
The SR 40 DUAL combines two SR 40 SINGLE receiver channels in one half-rack case. Each channel operates on a
separate frequency.
1 ON/OFF: On/off pushbutton switch with status LED.
2 Antenna (1 per channel): Fixed-length UHF antenna permanently mounted on the front panel.
3 VOLUME (1 per channel): This rotary control adjusts the receiver’s output level from microphone to line level for
matching to the input sensitivity of your mixer or amplifier.
4 RF OK (1 per channel): This LED illuminates to indicate that signal is being received. If no signal is received or the
automatic squelch is on, the RF OK LED goes out and the audio output is muted.
5 AF CLIP (1 per channel): This LED illuminates to indicate the audio level of the received signal is overloading the
receiver's audio section.
6 Color code lines: The color indicates the carrier frequency of the respective receiver channel. Both the SR 40 SIN-
GLE and the SR 40 DUAL have two color code lines. On the SR 40 SINGLE, both color code lines are of the same
color. Transmitters tuned to the same frequency are marked with the same color. Refer to the Manual Supplement
sheet for a color code table.

7 Carrier frequency label: A label indicating the carrier frequency (frequencies) and approval marks of your receiver
is affixed to the rear panel of the receiver.
8 AUDIO OUT (1 per channel): Balanced TRS 1/4" jack, adjustable from mic to line level. You can connect the out-
put either to an XLR microphone input or to an unbalanced line input on a mixer or amplifier.
9 Strain relief for the feeder cable of the supplied AC adapter.
10 DC ONLY: Input connector for the supplied AC adapter.
The automatic squelch circuit switches the receiver off if the received signal is too weak, in order to suppress the re-
lated noise or the residual noise of the receiver while the transmitter is off.
The HT 40 PRO handheld transmitter operates on a single fixed, quartz stabilized frequency in the 660 MHz to
865 MHz UHF carrier frequency range and uses an antenna integrated in the body.
The microphone element permanently mounted on the transmitter uses a high quality cardioid transducer from AKG. It
provides low handling noise sensitivity, high gain before feedback, and brilliant sound quality, as well as a built-in wind
and pop filter to reduce wind and breath noise.
11 On/off switch: This slide switch provides three positions indicated in the display window:
ON: Power to the transmitter is on.
MUTE: The signal delivered by the microphone element is muted while power and the RF carrier frequency remain
on.
OFF: Power to the transmitter is off.
12 Status LED: Indicates the transmitter's operating status.
LED lit green: Battery is OK.
LED lit red: From the moment the LED changes to red, the battery capacity will provide a maximum of two operat-
ing hours. We recommend replacing the battery with a new one as soon as possible.
• If you use a rechargeable battery, the LED will change to red 15 minutes before the battery will be dead!
13 Color code clip: The color of this plastic clip indicates the carrier frequency of your transmitter. Receiver channels
tuned to the same frequency are marked with the same color. Refer to the Manual Supplement sheet for a color code
table.
You can remove the color code clip on the HT 40 PRO and replace it with the supplied semitransparent clip.
14 Battery compartment lid: Refer to section 3.5.
15 Carrier frequency label: The label above the battery compartment indicates the carrier frequency and approval
marks of your transmitter.
You can use the PT 40 PRO bodypack transmitter with both dynamic microphones and condenser microphones oper-
ating on a supply voltage of approx. 4 V. You may also connect an electric guitar, electric bass, or remote keyboard.
The PT 40 PRO operates on a single fixed, quartz stabilized frequency in the 660 MHz to 865 MHz UHF carrier frequency
range.
16 On/off switch: This slide switch provides three positions indicated in the display window:
ON: Power to the transmitter is on.
MUTE: The signal delivered by the microphone element is muted while power and the RF carrier frequency remain
on.
OFF: Power to the transmitter is off.
17 Status LED: Indicates the transmitter's operating status.

The PT 40 PRO has been designed specifically for use with the following AKG microphones:
•CK 55 L, C 417 L, C 520 L, C 555 L
•C 516 ML, C 518 ML, C 519 ML
• The MKG L guitar cable from AKG lets you connect an electric guitar, electric bass, or remote keyboard to the body-
pack transmitter. One or two MKG L guitar cables, respectively, are included in the Instrumental Set SINGLE and In-
strumental Set DUAL. The MKG L guitar cable is also available separately as an accessory.
• Prior to setting up your WMS 40 SINGLE/DUAL, check that the transmitter and receiver are tuned to the same
frequency. The easiest way to do this is to compare the color codes on the transmitter and receiver.
• You can either use the receiver freestanding or mount it in a 19" rack using the optional RMU 40 rack mounting kit.
For instructions on how to rack mount the receiver, refer to the RMU 40 manual.
• 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, place the receiver as follows:
1. Place the receiver near the performance area (stage). Make sure, though, that the transmitter will never get 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 big metal objects, walls, scaffolding, ceilings, etc.
1. For each channel, use a balanced cable with an XLR connector and 1/4" TRS jack plug (available from electronics
or hi-fi stores).
2. Connect the (each) AUDIO OUT jack (8) on the receiver rear panel to the desired balanced (XLR) microphone input
on the mixer or amplifier.
3. Turn the (two) VOLUME control(s) (3) on the receiver all the way CCW to set the receiver output to mic level.
1. Use a standard 1/4" jack cable to connect the (each) AUDIO OUT jack (8) on the receiver rear panel to an unbal-
anced 1/4" line input jack on the mixer or amplifier.
2. Turn the (two) VOLUME control(s) (3) on the receiver all the way CW to set the receiver output to line level.
• To avoid hum interference, do not use any audio cables that are longer than 10 feet (3 m)!
1. Check that the AC mains voltage stated on the included power supply is identical to the AC mains voltage
available where you will use your system. Using the power supply with a different AC voltage may cause
damage to the unit.
2. Point the antenna(s) (2) upward.
3. Plug the feeder cable on the included power supply into the DC ONLY socket (10) on the receiver.
4. Bend part of the feeder cable into a small bight, pass the bight through the strain relief (9) from above, and slip the
bight over the hook on the strain relief (9). Tighten the cable.
5. Plug the AC adapter into a convenient power outlet.
6. Press the ON/OFF switch (1) to switch power to the receiver ON.
1. Depress the snap hook on the battery compartment lid (14)/(21).
2. Pull the battery compartment lid (14)/(21) off the transmitter in the direction of the arrow.
3. Insert the supplied battery into the battery compartment conforming to the polarity marks.
The transmitter will not function if you insert the battery the other way round.
4. Set the on/off switch (11)/(16) to "ON" to switch power to the transmitter on.
If the battery is in good condition, the status LED (12)/(17) will be lit green.
If the status LED (12)/(17) is lit red, the battery will be dead within about two hours. Replace the battery with a new
one as soon as possible.
If the status LED (12)/(17) fails to illuminate the battery is dead. Insert a new battery.

A handheld vocal microphone provides many ways of shaping the sound of your voice as it is heard over the sound sys-
tem.
The following sections contain useful hints on how to use your HT 40 PRO handheld transmitter for best results.
Basically, your voice will sound the 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, insinuating, etc. simply by changing your work-
ing distance.
Proximity effect is a more or less dramatic boost of low frequencies that occurs when you sing into the microphone from
less than 2 inches. It gives more "body" to your voice and an intimate, bass-heavy sound.
Sing to one side of the microphone or above and across the microphone’s top. 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 overemphasize "sss",
"sh", "tch", "p", and "t" sounds.
Feedback is the result of part of the sound projected by a speaker being picked up by a microphone, fed to the ampli-
fier, and projected again by the speaker. Above a specific volume or "system gain" setting called the feedback thresh-
old, the signal starts being regenerated indefinitely, making the sound system howl and the sound engineer desperately
dive for the master fader to reduce the volume and stop the howling.
To increase usable gain before feedback, the microphone element of the HT 40 PRO handheld transmitter has a car-
dioid polar pattern. This means that the microphone is most sensitive to sounds arriving from in front of it (your voice)
while picking up much less of sounds arriving from the sides or rear (from monitor speakers for instance).
To maximize gain before feedback, place the main (aka "FOH" - front of house) 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 FOH speakers.
Feedback may also be triggered by resonances depending on the acoustics of the room or hall.With resonances at low
frequencies, proximity effect may cause feedback. In this case, it is often enough to move away from the microphone
a little to stop the feedback.
1. Never let more than two persons share a microphone.
2. Ask your backing vocalists never to sing more than 35 degrees off the microphone axis.
The microphone is very insensitive to off-axis sounds. If the two vocalists were to sing into the microphone from a
wider angle than 35 degrees, you may end up bringing up the fader of the microphone channel far enough to cre-
ate a feedback problem.
1. Fix the microphone to the supplied lavalier clip or to the optional H 41/1 tiepin.
2. Clamp the microphone on your clothing as close as possible to the talker's mouth.
• Remember that gain-before-feedback will be the higher the closer the microphone sits to the user's mouth!
3. Make sure to aim the microphone at the user's mouth.
1. Put the microphone on.
2. Bend the gooseneck so that the microphone will sit to one side in front of the corner of your mouth.
• You can adjust the microphone to conform exactly to the shape of the user’s head. For details, refer to the C 555 L
instruction manual which you can download from www.akg.com.
• Should you hear excessive pop noise ("p" and "t" sounds are overemphasized unnaturally), move the microphone
capsule further away from your mouth (up or back).
• If the microphone sounds "thin" or flat, move the microphone capsule closer to your mouth (refer to fig. 3).
• Find the optimum position during the soundcheck.
If (for instance,on an open-air stage) excessive wind or pop noise becomes audible, attach the supplied windscreen to
the microphone.
1. Slide the windscreen onto the microphone capsule.
2. Pull the windscreen over the outer edge of the microphone capsule.
A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to penetrate into the
microphone. This barrier prevents the microphone sound entries from being clogged by perspiration or makeup, which
would make the sound dull and reduce the sensitivity of the microphone. Therefore, never remove the moisture shield
from the microphone!
In case the moisture shield is damaged or lost, the C 555 L head-worn microphone includes a replacement moisture
shield.
