ARCHITECT‘S SPECIFICATION
A complete professional audio system for web and tele-
conferencing applications in standard meeting rooms,
comprised of a central unit, a combox and other devices
such as microphones and active loudspeakers.
The audio system shall be capable of simultaneous multip-
le conferencing operation, i.e. capable of allowing users to
combine several conferences set up on different connecti-
on types (e.g. a web conference via Skype, a teleconferen-
ce via landline and a mobile phone conference via GSM)
into one conference where all participants can interact
with each other simultaneously.
The central unit shall be an automatic mixer for professio-
nal quality audio in multiple microphone web and telecon-
ferencing applications. It shall provide advanced mixing
capabilities and configuration options. All devices used
in the system shall be connected, directly or indirectly, to
the central unit. The central unit shall be equipped with
a TELCO telephone interface. An Ethernet port shall be
provided for network connections. The central unit shall
feature an RS-232 control port for connecting a third party
media control system (Creston, AMX, etc.). The central unit
shall have a USB 2.0 port for connecting a PC for confi-
guration purposes and shall also be configurable via the
RS-232 port or the network (Ethernet port). The required
“Configuration Manager“ PC software for configuring the
central unit and all other components shall be supplied.
The central unit shall feature eight mic/line inputs (each
with 24V switchable phantom power), two additional line
inputs and eight audio outputs for connecting e.g. active
loudspeakers. The central unit shall work with any micro-
phone with a standard terminal connector. The central unit
shall support mono and stereo acoustic echo cancellation,
i.e. one or two out of the eight outputs shall be selectable
as the acoustic echo cancellation reference. If all eight
output channels do not suit the echo cancellation needs,
two freely configurable virtual reference channels shall
be selectable as the reference for echo cancellation. The
connection between the central unit and the combox shall
be made by means of a standard CAT5 cable.
The combox shall be “plug and play” (no drivers required)
and shall be the system’s audio interface, allowing the
system to be used as an audio extension. The combox shall
be used to process computer audio as well as headset or
enterprise telephone audio in the system. The USB 2.0 port
of the combox shall allow the connection of a PC. Via the
combox, the system shall be capable of playing back all
audio from the PC (e.g. web conferences, any audio and
video content) as well as picking up and processing the
audio in the meeting room and feeding it back to the PC. In
addition, any device with a 4-pin 3.5 mm jack socket (e.g.
a mobile phone or tablet PC) shall be connectable to the
combox’s headset socket via a 4-pin special cable, thus
allowing audio from the mobile device to be processed in
the system. The combox shall not be required for telecon-
ferencing via landline.
Using the “TeamConnect“ dialer iOS app for iPad/iPhone
or the browser-based dialer (e.g. computer, Android tablet
PCs, …), the central unit shall be remote controllable. The
dialer used shall be capable of establishing the landline
connection for teleconferencing and shall include remote
control functions for the overall system (e.g. selecting and
applying previously saved configuration presets, adjusting
the volume, muting the whole system and accessing a
phone book).
The microphones shall be pre-polarized condenser
boundary layer microphones operating on 24V phantom
power. The microphone capsules shall be optimized for
speech intelligibility. The microphones shall be available as
surface-mounted versions with either an omni-directional
or a cardioid pick-up pattern and as a tabletop version with
a cardioid pick-up pattern. The tabletop version shall also
be available as an -S variant with a programmable micro-
phone button (toggle on/off, PTM, PTT and permanent on)
and a bi-color LED ring for status indication. The surfa-
ce-mounted microphones shall be available as -L variants
featuring an XLR-5 connector and a bi-color LED ring.
The loudspeaker shall be active and optimized for speech
intelligibility. Its high, medium and low frequency levels
shall be adjustable in order to obtain optimum sound
quality depending on the mounting position of the speaker
and the room characteristics. The loudspeaker shall have 2
power modes: on and auto standby. The loudspeaker‘s high
pass filter shall be adjustable to 50 Hz, 70 Hz or 100 Hz.
The input sensitivity shall be selectable between -6 dBu,
0 dBu or +10 dBu. The loudspeaker shall come complete
with a wall mounting kit and, when wall mounted with the
supplied spacers, shall be pivotable by 180° and tiltable.
Up to eight loudspeakers shall be connectable to the cen-
tral unit.
Dimensions shall be as follows: central unit: 432 x 191 x
51 mm (17“ x 7.5“ x 2“); combox: 119 x 143 x 44 mm (4.7“ x
5.6“ x 1.7“); tabletop boundary layer microphone: 85 x 100 x
25 mm (3.35“ x 3.94“ x 0.98“); surface-mounted boundary
layer microphone: 28.5 mm (1.12“) in diameter and 83 mm
(3.27“) in total height, installation height shall be 12 mm
(0.57“); loudspeaker: 240 x 140 x 161 mm (9.45” x 5.51” x
6,34”). Approximate weights shall be as follows: central
unit: 2.25 kg (4.5 lbs.); combox: 0.75 kg (1.51 lbs.); table-
top boundary layer microphone: 291 g (10.27 oz); surfa-
ce-mounted boundary layer microphone: 58 g (2.05 oz);
loudspeaker: 3.1 kg (6.83 lbs.).
The devices shall be manufactured by Sennheiser and shall
be as follows: central unit shall be type CU1; combox shall
be type CB1; tabletop boundary layer microphones shall be
type MEB 114 and MEB 114-S; surface-mounted boundary
layer microphones shall be type MEB 102 and MEB 104 and
their -L variants; loudspeaker shall be type SL Loudspeaker
