Sennheiser SpeechLine – True to the word

The spoken word remains the most personal and powerful tool in communication. It enables us to convey and exchange messages, thoughts and opinions, as well as emotions. Therefore, when using technical devices like microphones, it is most important that no content is lost or misunderstood.

The best microphone is one you don't have to think about while speaking, because it fully captures your voice and picks up your words as precisely as you form them. Easy operation and clear speech intelligibility are perhaps most popularly embodied in the characteristically shaped Sennheiser ME 36, which can be seen on virtually every TV news program.

The qualities of these iconic microphones can also be found in all other microphones of the versatile Sennheiser SpeechLine series. These qualities are also built into any microphone of the versatile Sennheiser SpeechLine portfolio.

Wired or wireless, digital or analog, this comprehensive range of easy to integrate and unobtrusively designed microphones offer a solution for just about any situation, including yours.

In many applications, a speech microphone can help to increase the speech intelligibility or even make it possible in the first place (as in teleconferences). The following chapters describe the most common applications.

Typical applications

Illustration of two business people seated at a round table with city skyline in background (no text or symbols)

A) Conferences (voice lift)

The larger the room, the more helpful is an audio system which enhances the speech intelligibility. Especially in large conference rooms, a speaker seated at one end is difficult to understand at the other end ceiling microphones can be used to pick up what the speaker says. The audio signal can then be spread evenly around the room using wall or ceiling loudspeakers. This application is also known as “voice lift”, i.e. the speech is amplified in the room.

Table or

B) Teleconferences

If the participants of a conference are seated in different rooms, they have to be connected via telephone or remote conference circuit. As a telephone alone can only offer inadequate speech transmission for all participants in the room, table or ceiling microphones should be used in this case too. These are connected to a telephone conference unit such as the Sennheiser TeamConnect system. This processes the signals and establishes the connection to the remote participant.

C) Presentations

Especially in a presentation, in which the focus is on the transmission of content, it is important to understand every word. Here, too, the larger the room, the more necessary it is to amplify the voice. In this case, gooseneck microphones offer the speaker orientation and enhance his presentation.

Typical ways of setting up and installing microphones

Mobile microphones:

Permanently installed microphones:

Illustration of a business meeting with three people at a podium, cityscape background, and pie charts showing percentage distribution (no text or symbols)

A) Table

Especially in conference rooms, an obvious solution is miking up the table. Here all participants are seated around the table. Sennheiser offers mobile solutions as well as permanently installed microphones. The mobile microphones are simply placed on the table.

Mobile installation: Permanent installation:

Suspending a microphone from the ceiling is another alternative. It has the advantage that the microphones can be installed virtually invisibly in the room. Ceiling installation requires precise prior planning, as the microphones are further away from the speaker and the speech intelligibility can be impaired by noise coming from the ventilator of a projector or from an air conditioning unit.

C) Lectern

A lectern is usually used for presentations. Here, too, the microphones can be positioned temporarily or installed permanently. A gooseneck microphone positions the microphone capsule close to the speaker, thus ensuring maximum speech intelligibility. Flexible gooseneck microphones prevent conflicts with laptops because they can be oriented flexibly.

D) Floor

For spontaneous presentations or panel discussions, floor stands provide a solid base for a gooseneck microphone.

Pick-up patterns of the microphones

Omni-directional pick-up pattern

An omni-directional pattern picks up the sound uniformly from all directions.

Cardioid pick-up pattern

A cardioid pattern has a wide directional characteristic, i.e. a wide opening angle. Sound hitting the rear of the microphone is attenuated very strongly.

Super-cardioid pick-up pattern

A super-cardioid pattern has a slightly stronger directional characteristic than the cardioid pattern, so it suppresses noise coming from the side even more strongly but also picks up some of the sound coming from the rear.

Super-cardioid | lobar pick-up pattern

A super-cardioid or lobar pattern has the strongest directional characteristic, i.e. it provides the maximum suppression of sound coming from the side, but it also picks up sound coming from the rear. However, the ratio is lower than it is with the super-cardioid pattern.

Positioning the microphones

A) Distance from the speaker

Basically, the nearer a speaker is to the microphone, the higher the speech intelligibility. For this reason, gooseneck microphones are optimal from an acoustic point of view. They position the microphone capsule close to the speaker while offering excellent orientation.

Boundary layer microphones do not achieve the excellent acoustic characteristics of gooseneck microphones, but they can be positioned especially unobtrusively. These microphones can be integrated into any room due to their small size and the colors they are available in. As a result of the so-called boundary layer effect, the signal picked up by the microphone capsule is amplified on a surface (for example a table or a ceiling panel). In this way, part of the distance to the speaker can be compensated for again.

B) One microphone for each speaker

In the ideal case, a dedicated microphone is used for each speaker. This allows the best possible orientation and distance to the speaker to be ensured at all times. It is also possible to choose a narrower directional characteristic. This allows noise coming from the side as well as acoustic reflections to be minimized, resulting in the highest speech intelligibility.

C) "Shared microphones" - several speakers share one microphone

One microphone per speaker is ideal, but one microphone shared by two speakers is often adequate for many applications. A microphone with a sufficiently wide opening angle should be selected here. The microphone can thus pick up both speakers if installed centrally before them.

Illustration of two people at a podium with microphones, one speaking and the other listening (no text or symbols present)

D) Typical table shapes - U-shaped, round, long, rows

Abstract geometric pattern composed of white blocks on a dark background, no text or symbols present

Depending on the configuration of the tables in a room, different microphones can be selected. In the case of a small round table, for example, a microphone with an omni-directional pick-up pattern (shown as a blue circle) is adequate to pick up all participants uniformly. Directional microphones (shown as a semicircle) are suitable for rows of tables. These microphones minimize the sound coming from the rear and the sides. In oblong conference rooms with long tables, a combination of directional and omni-directional microphones can be a good solution.

E) Speaker is seated

For conferences in which the speakers are seated, planning is easy as the distance between the speaker and the microphone is easy to estimate or measure. Here, the microphone is simply placed on the table and oriented towards the speaker.

F) Speaker is standing

In the case of presentations held at a lectern, the speaker is usually in a standing position. Here, the distance between lectern and mouth is virtually as large as it is with a seated speaker. In courtrooms, the speakers frequently stand up although the table in front of them is often of "normal" height. In this case, long gooseneck microphones should be used ideally in order to reduce the distance between the microphone capsule and the speaker.

Illustration of two people at a podium with microphones, one speaking and the other listening (no text or symbols present)

Typical acoustic situations

A) Normally attenuated room

A normally attenuated room provides an average attenuation of reflections. This is contributed to by carpets, curtains or special acoustic ceilings. In the case of reduced reflections in the room, microphones pick up less noise, which results in the highest speech intelligibility.

B) Room with amplified sound

If the speech in the room is amplified by loudspeakers, this signal can enter the microphone again. This can cause echo, but in the worst case acoustic feedback can be the result. The effect can be reduced by using microphones with stronger directional characteristics.

C) Large rooms with echo – acoustically challenging rooms

The larger the room, the more probable is acoustic disturbance due to reflections or sound coming from loudspeakers. If the room also has many smooth surfaces such as glass fronts or smooth floors, the result is a scenario which is extremely unfavorable acoustically. In this case, only microphones with strong directional characteristics like the ME 36 can ensure speech intelligibility.

Connecting the products

Connecting the products to an audio input

There are two ways to connect the products of the SpeechLine IS microphone series to a suitable audio input:

A) Connection to a mixing console, an auto mixer or a digital signal processor (DSP) using shielded cables
B) Connection to a mixing console via the MAS 133 inline switch box and the MAS 1 microphone button using shielded XLR cables
A) Connecting a microphone to a mixing console | an auto mixer | a digital signal processor (DSP)
Use a suitable shielded cable (e.g. XLR-XLR, XLR-terminal) to connect the microphone to the mixing console, the auto mixer or the DSP. For more information on the connections, refer to the instruction manual of your DSP.
Lay all cables in such a way that other persons cannot trip over them and injure themselves.

Connecting products via the logic function

Once you have established the audio connection (see previous chapter), you can connect the products of the IS microphone series featuring a logic port (shown on the left) to the DSP.

The logic port passes on status information on the microphone button (microphone button pressed/ not pressed) to the DSP. Via the logic output of the DSP, you can additionally control the status of the signal light ring of the microphone button.

The logic output also allows you to integrate and control several MAS 133 inline switch boxes in a system.

The following chapters provide

A) information on how to connect the MAS 133 inline switch box to a DSP
B) information on how to connect microphones
C) an example installation for the Se nnheiser TeamConnect system

A) Connecting the MAS 133 inline switch box to the DSP via the logic function

The way you connect the MAS 133 inline switch box determines which information is passed on to the DSP.

Logic port Function

Passes on status information on the microphone button – button pressed/ not pressed– to the DSP.

Passes on microphone status information – microphone activated/muted – to the DSP.

Use a 2-wire cable ( 0.14–0.5 mm ^2 ) to connect the inline switch box to a GPIO port or logic port of the DSP.
Lay all cables in such a way that other persons cannot trip over them and injure themselves.
▶ Observe the connection instructions in the instruction manual of your DSP.

DSP logic MENHEISER MAS 133 Switch signal out DSP control

B) Connecting microphones to a DSP with logic function

To establish a logic connection in addition to the audio connection:

Use a 3-wire cable ( 0.14–0.5 mm ^2 ) to connect the microphone or the table stand to a GPIO port or logic port of the DSP.
Lay all cables in such a way that other persons cannot trip over them and injure themselves.
Observe the connection instructions in the instruction manual of your DSP.

▶ Set the slide switch for setting the behavior of the microphone button to ON in order to activate the "DSP remote mode". In "DSP remote mode", the microphone is permanently on and is muted or activated via the DSP. The microphone thus permanently provides a reference signal for AEC algorithms in the DSP.

Adjusting and using the products

Adjusting the microphone sensitivity

Use the mixing console, the auto mixer or the DSP to adjust the microphone sensitivity so that over- or under-modulation is avoided. For more information on the audio settings, refer to the instruction manual of the corresponding device.

If interference occurs at high field strengths, remove the source of interference from the microphone.

Activating/deactivating the low-cut filter on the MEB 114 (-S)

A table or lectern transfers the sound produced when a speaker accidentally stumbles against it. The low-cut filter reduces low-frequency noise by filtering out frequencies below 120 Hz.

▶ Set the slide switch to the desired position:

Low-cut filter is deactivated

Low-cut filter is activated

Setting the behavior of the microphone button

The products shown on the left feature a slide switch that allows you to directly set the behavior of the microphone button.

▶ Set the slide switch to the desired position.

Position Function

ON/OFF:

When you press the microphone button, the microphone is:

- activated (lights up green) or

- muted (lights up red).

PTM – Push To Mute:

The microphone is activated, the microphone button lights up green. The microphone button will light up red and the microphone will be muted for as long as you keep the microphone button pressed.

PTT – Push To Talk:

The microphone is muted, the microphone button lights up red. The microphone button will light up green and the microphone will be activated for as long as you keep the microphone button pressed.

ON:

- Protection against accidental operation: The microphone is permanently activated. This setting prevents interruptions due to accidental operation of the microphone button.

- DSP remote mode: The microphone is connected to a DSP via a logic port. In this case, the functions ON, OFF, PTT and PTM can be performed by the DSP.

Activating/muting microphones

The products shown on the left have LEDs that indicate whether the microphone is muted or activated. The LEDs light up as so products are powered via the mixing console, the auto mixer or the DSP.

Whether a microphone is permanently activated or muted or whether it can be activated or muted by pressing the microphone button depends on the setting of the slide switch that sets the behavior of the microphone button (see page 32). When the slide switch is set to ON, the microphone is permanently activated and the microphone button is deactivated.

▶ Press the microphone button, the LED lights up:

... green Microphone is active
