The HT 40 handheld transmitter oper- ates on one fixed, quartz stabilized fre- quency in the 710 MHz to 865 MHz UHF carrier frequency range and uses an antenna integrated in the body. The microphone element permanentiy mounted on the transmitter is acousti- cally identical to the D 880 vocal micro- phone from AKG. This microphone fea- tures a built-in wind and pop filter to reduce wind and breath noise and pro- vides low handling noise sensitivity, high gain before feedback, and brilliant sound quality.

2.5 Controls (See fig. 1 on page 13)

1 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. This pre- vents the receiver from respon- ding to interference from other transmitters. OFF: Power to the transmitter is off. 2 Status LED: Indicates battery status. LED flashes momentarily upon switching ON and extinguishes: batteries are OK. LED lights constantiy: batteries will be dead in about 50 minutes. 3 Color Code: The color of this plastic clip indicates the carrier frequency of your transmitter. Receivers tuned to the same frequency are marked with

the same color (refer to section 2.6). You can remove the color code clip on the HT 40 and replace it with the supplied black clip. 4 Battery Compartment Lid: Refer to section 3.2. 5 Carrier Frequency Label: The label above the battery compartiment indicates the carrier frequency and approval marks of your transmitter.

83 Setting Up Important: Prior to setting up your WMS 40, 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.

3.1 Placing the Receiver

Reflections off metal parts, walls, cei lings, etc. or the shadow effects of musi- cians 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 perform-

ance area (stage). Make sure, though, that the transmitter will never get any closer to the receiver than 10 ft (8 m). Optimum separation is 16 ft. (5 m).

2. Check that you can see the receiver

from where you will be using the transmitter.

8. Place the receiver at least 5 ft. (1.5 m)

away from any big metal objects, walls, scaffolding, ceilings, etc.

3.2 Inserting and Testing Batteries

1. Depress the snap hook on the battery

compartment lid (4).

2. Pull the battery compartment lid (4)

down to remove it from the trans- mitter. Important: The foam pads on the inside of the battery compartment lid holds the batteries in place. Do not remove the foam pad. If you do, the batteries will not be held in place properly and may cause a rattling noise. 1.5V Fig. 2: Inserting the batteries.

3. Insert the supplied batteries into the

battery compartment conforming to the polarity marks. The transmitter will not function with incorrectly inserted batteries. . Set the onoff switch (1) to “ON” to switch the power to the transmitter on. The status LED (2) will flash momen- tarily. Ifthe batteries are in good con- dition, the status LED (2) will extin- guish. If the status LED (2) illuminates the batteries will be dead within about 50 minutes. Replace the batteries with new ones as soon as possible. If the status LED (2) fails to flash momentarily the batteries are dead. Insert new batteries. . To close the battery compartment, slide the battery compartment lid (4) onto the battery compartment from below to the point that it will click shut.

Switch power to the receiver on and check the setting of the VOLUME control: Fully CCW if you connected the receiver to a microphone input. Fully CW if you connected the receiver to a line input. . Set the on/off switch (1) to “ON” to switch power to the transmitter on. Since the HT 40 handheld transmitter has been designed specifically for the integrated microphone element, there is no need to set gain on the handheld transmitter. Therefore, the handheld transmitter has no level or gain control. Switch power to your sound system or amplifier on. Talk or sing into the microphone and set the levels on your mixer or ampli- fier referring to the appropriate instruction manual or by ear.

3.4 Replacing the Color Code Clip

(Refer to fig. 3) Fig 3: Replacing the color code clip.

1. Use a screwdriver to lift the upper

end of the color code clip.

transmitter to the point that it snaps into place with an audible click.

1. Move the transmitter around the area

where you will use the system to check the area for "dead spots", ie., places where the field strength seems to drop and reception deteriorates. If you find any dead spots, try to elim- inate them by repositioning the receiver. If this does not help, avoid the dead spots.

2. The RF LED on the receiver going out

means no signal is being received or the squelch is active. Switch power to the transmitter ON and/or move closer to the receiver, to the point that the RF LED on the receiver will come back on. 4 Microphone Technique 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 40 hand- held transmitter for best results.

4.1 Working Distance and Proximity

Effect 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 agressive, neutral, insinuating, etc. simply by changing your working distance. Proximity effect is a more or less dramatic boost of low frequencies that occurs when you sing into the micro- phone from less than 2 inches. It gives more “body” to your voice and an intimate, bass-heavy sound.

4.2 Angle of Incidence (See fig. 4)

Fig. 4: Angle of incidence 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.

4.3 Feedback (Refer to fig. 5)

Feedback is the result of part of the sound projected by a speaker being picked up by a microphone, fed to the amplifier, and projec- ted again by the speaker. Above a specific volume or “system gain” setting called the feedback threshold, the signal starts being regenerated indefinitely, making the sound system howl and the sound engineer despe- rately dive for the master fader to reduce the volume and stop the howling. To increase usable gain before feed- back, the microphone element of the HT 40 handheld transmitter has a super- cardioid polar pattern. This means that the microphone is most sensitive to Fig. 5: Feedback

sounds arriving from in front of it (your voice) while picking up much less of sounds arriving from the sides or rear (rom monitor speakers for instance).main (“FOH) speakers in front of the microphones (along the front edge of the stage). If you use monitor speak- ers, be sure never to point any micro- phone 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 micro- phone a little to stop the feedback.

4.4 Backing Vocals (Refer to fig. 6)

1. Never let more than two persons

2. Ask your backing vocalists never to

sing more than 85 degrees off the

Fig. 6: Backing vocals. 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 create a feedback problem.

For troubleshooting hints, refer to the instruction manual of your receiver. 5 Cleaning

To clean the transmitter case, use a soft cloth moistened with water.

5.2 Internal Windscreen

1. Unscrew the wire-mesh cap of the

handheld transmitter CCW and remo- ve the wire-mesh cap from the trans- mitter.

2. Remove the windscreen (foam sheet)

from the wire-mesh cap.

3. Wash the windscreen in mild soap

4. As soon as the windscreen has dried,
