Overview of the SpeechLine Wired series
Sennheiser SpeechLine Wired – Word for word
The spoken word is and remains the most personal and powerful instrument of
communication we know.
It allows us to voice opinions, thoughts and views as well as emotions. This is why it is so
important that when using technical aids, such as microphones, none of the content is lost or
misunderstood.
The best microphones are those that the speaker does not have to think about while speaking
because they capture the voice easily and record words as clearly and precisely as they are
spoken. Perhaps the best-known microphone, which combines ease of use with high speech
intelligibility, is the characteristically designed Sennheiser ME 36, which can be seen in
almost every television news broadcast.
The qualities of this classic can also be found in all the other microphones in Sennheiser’s
versatile SpeechLine Wired series.
Whether wireless or wired, digital or analog, this comprehensive series of user-friendly, easy-
to-integrate and discreetly designed microphones offers a solution for every scenario.
In many applications, a speech microphone can help to increase speech intelligibility or even
make it possible in the first place (e.g. for telephone conferences). The following chapters
describe the most common use cases.
5
| 2 - Product information
Typical applications
Conferences (voice lift)
The larger the room, the more helpful is an audio system which enhances speech
intelligibility. In large conference rooms in particular, a speaker seated at one end is difficult
to understand at the other end. Table or ceiling microphones can be used to record the
speaker. The audio signal can then be distributed evenly throughout the room via wall or
ceiling speakers. This application is also known as voice lift, as the speech is amplified in the
room.
Teleconferencing
If not all participants in a meeting are sitting in the same room, they must join via telephone
or remote conference. Since a telephone alone cannot provide adequate voice transmission
for all participants in the room, table or ceiling microphones should also be used in this case.
These are connected to a teleconference unit such as the Sennheiser TeamConnect system.
This processes the signals and establishes the connection to the remote participants.
Presentation
Particularly for presentations, where the focus is on conveying content, it is important that
every word can be understood clearly. Again, the larger the room, the more important it is to
amplify the voice. In this case, gooseneck microphones provide orientation for the speaker
and support their presentation.

Table
In meeting rooms in particular, it is useful to have a microphone on the table. All participants
then sit around the table. Sennheiser offers both mobile solutions and built-in microphones.
Simply place the mobile microphones on the table.

8

Ceiling
%
An alternative is miking from the ceiling. The advantage of this approach is that the
microphones can be installed in such a way that they are practically invisible in the room.
Ceiling mounting requires precise planning as the microphones are further away from the
speaker and the speech intelligibility may be impaired by fan noise from a projector or air
conditioning system.
Lectern
A lectern is usually used for presentations. Here too, microphones can be placed temporarily
or permanently installed. A gooseneck microphone brings the microphone capsule close
to the speaker thereby ensuing maximum speech intelligibility. Flexible goosenecks avoid
conflicts with laptops as they can be flexibly aligned.
9
| 2 - Product information
Floor
For spontaneous presentations or panel discussions, floor stands provide a solid base for a
gooseneck microphone.
10
| 2 - Product information
Microphone pick-up patterns
Omni-directional polar pattern
The omni-directional picks up sound information evenly in all directions.
Cardioid polar pattern
The cardioid features broad directivity and a wide apex angle. Sound that hits the back of the
microphone is attenuated the most.
Supercardioid polar pattern
11
| 2 - Product information
The supercardioid is slightly more directional than the cardioid, meaning it suppresses even
more noise from the side, but also picks up some sound from behind.
Supercardioid | lobar polar pattern
The supercardioid or lobar has the strongest directional effect, i.e. the greatest suppression
of sound from the side, but also absorbs sound from behind. However, the ratio is lower here
than with the supercardioid.
12
| 2 - Product information
Positioning of the microphone type
Speaking distance
As a rule of thumb, 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 and at the same time
provide excellent orientation.
While boundary microphones do not quite achieve the excellent acoustic properties of
gooseneck microphones, they can be positioned extremely inconspicuously. Thanks to their
small size and appropriate colors, these microphones can be integrated into any room. Due
to the so-called boundary effect, the signal picked up by the microphone capsule is amplified
on the surface (e.g table or ceiling panel). This compensates for some of the distance to the
speaker.
One microphone for each speaker
Ideally, each speaker will use a dedicated microphone. This ensures the best possible
alignment and distance to the speaker at all times. The directivity can also be made
narrower to minimize lateral noise and acoustic reflections. This ensures the highest speech
intelligibility.
“Shared mics” – several speakers share a microphone
One microphone per speaker is ideal, but for many applications one microphone for two
people is sufficient. In this case, you should select a microphone with a wide enough apex
angle for the recording. This allows the microphone to pick up both speakers when installed
centrally in front of them.
Typical table shapes – U, round, long tables, rows
Different microphones can be selected depending on the arrangement of the tables in a
room. With a small, round table, for example, an omni-directional microphone (shown as
a blue circle) is sufficient to pick up all meeting participants evenly. For rows of tables,
directional microphones (shown as a semicircle) are more suitable, as they minimize the
13
| 2 - Product information
sound from the back and sides. In long meeting rooms with long tables, a combination of
directional and omni-directional microphones can be a solution.
Speaker in sitting position
For meetings in which speakers are seated, planning is straightforward, as the distance to
the microphone can be easily estimated or measured. The microphone is simply placed on
the table in the direction of the speaker.
Speaker standing
In the case of presentations at a lectern, speakers are usually standing. Here the distance
between the lectern and the speaker’s mouth is similar to that when sitting. In courtrooms,
speakers often stand, while the table in front of them is usually at “normal” height. In this
case, long gooseneck microphones should ideally be used to ensure proximity to the speaker.
14
| 2 - Product information
Typical acoustics
Normally damped room
A normally damped room has an average attenuation of reflections. Carpets, curtains or
special acoustic ceilings make a positive contribution to this. When acoustic reflections in the
room are reduced, microphones pick up less “noise” and speech intelligibility is at its highest.
Room with sound system
If speech is amplified by loudspeakers in the room, this signal can also get back to the
microphone as an echo or, in the worst case, acoustic feedback. This effect can be reduced
by using more directional microphones.
Large/reverberant room – Acoustically challenging rooms
The larger the room, the more likely it is for acoustic interference to occur due to reflections
or sound from loudspeakers. If there are also lots of smooth surfaces, such as glass fronts or
smooth floors, this represents a very unfavorable acoustic scenario. In this case, only highly
directional microphones such as the ME 36 can ensure speech intelligibility.

Connecting products via the logic function
Once you have established an audio connection (see Connecting products to an audio input),
you can also connect certain products in the SpeechLine Wired series to the digital signal
processor (DSP) via a logic port.
The logic port forwards the switching information of the microphone button (pressed/not
pressed) to the DSP. You can also use the logic output on the DSP to control the status of the
luminous ring on the microphone button.
The logic output also allows several MAS 133 switch boxes to be integrated and controlled in
a system.
The following chapters show
• A) how to connect the MAS 133 switch box to a digital signal processor (DSP) or
• B) to the microphone

signal processor (DSP) so that it neither is neither overdriven nor underdriven. For
more information about the audio settings, see the instruction manual for respective
device.
If interference occurs in the microphone at high field strengths, remove
the source of interference from the microphone.

Setting the “low-cut” filter on the MEB 114 (-S)
Tables and lecterns transmit sound if the speaker accidentally bumps into them,
for example. The “low-cut” filter enables frequencies under 120 Hz to be filtered
out and interference reduced.
Slide the switch to the desired position.

Setting the switching behavior of the microphone
On the products shown here, you can set the switching behavior of the microphone directly
using a slide switch.
Slide the switch to the desired position.
ON/OFF
As soon as you press the microphone button, the microphone
is:
• Activated (lights up green) or
• Muted (lights up red).
PTM - Push to mute
57
| 3 - User manual
The microphone is active, the microphone button lights up green. As
long as you keep the microphone button pressed, it lights up red and
the microphone is muted.
PTT - Push to talk
The microphone is muted, the microphone button lights up red. As long
as you keep the microphone button pressed, it lights up green and the
microphone is activated.
ON
• Protection against incorrect operation: The microphone is
permanently activated. This setting prevents interruptions
caused by accidentally pressing the microphone button.
• DSP remote mode: The microphone is connected to a digital
signal processor (DSP) via a logic connection. In this settings,
the ON, OFF, PTT and PTM functions can be taken over by the
digital signal processor (DSP).

Muting/activating microphones
These products use LEDs to indicate whether the microphone is muted or activated. The
LEDs light up as soon as the products are supplied with power via the mixing console, auto
mixer or the digital signal processor (DSP).
You use the switching behavior to determine whether a microphone is permanently activated
or muted or whether a button press switches between these states (see Setting the
switching behavior of the microphone). In the ON setting, the microphone is always active
and the microphone button is deactivated.
Press the microphone button; the LED lights up:
• green = microphone is active
• red* = microphone is muted
*This function is not supported by all mixing consoles, auto mixers and digital signal
processors (DSP).
The luminous rings on the microphones and switches light up synchronously.
