ARCHITECT’SSPECIFICATIONS
The control unit shall be the core of a digital wireless discussion
system. The DSSS modulation shall ensure high immunity from
interference in the frequency range of 2.4 / 5.2 and 5.8 GHz. The
HD- High Definition audio mode shall provide an audio bandwidth
of 24 KHz and a sampling rate of 48 KHz. The HQ- High Quality of
service mode shall be used for a user-optimised transmitting and
receiving performance in difficult environments in terms of radio
transmission. The AVB (Audio Video Bridging) input and output for
digital signal transmission in building networks shall be compliant to
the IEEE 801.1 standards. The true diversity antenna technology
shall ensure highest transmission reliability. The digital 128-bit
encryption shall include an additional 24-bit PIN code. There shall be
an automatic recognition of interferences in all frequency ranges.
The silent change to an interference-free frequency range shall be
automatic or manual according to the EN 300328 ETSI. The control
unit shall manage up to 150 microphone units. There shall be
4 audio up-streams for up to 4 microphone signals. There shall be
2 audio down-streams for loudspeaker transmission and headphone
output. The NOM - Number of open Microphones function shall
allow the allocation of up to 4 microphone units simultaneously.
The audio channel allocation of the microphone units shall be
processor-controlled and automatic. The control unit shall feature
different operating modes: Manual – each participant can turn the
microphone on and off; Voice Activation – the microphone is turned
on when someone speaks into it; Override – when a microphone
unit is activated, the one that was activated before will be turned
off; Push-To-Talk – as long as the participant speaks into the micro-
phone, he/she must press the microphone button. For flexible audio
routing there shall be an integrated DSP. Zoning – the output
channel allocation of individual microphone units shall be divided
into 4 different audio zones analogue or digital via AVB. With the
Mix-Minus function the system shall be integrated into tele and
video conferences. The control unit shall feature a fully parametrical
4-band equalizer for microphone unit loudspeakers and master
output, a NOM attenuation for the master output and individual
audio zone outputs as well as an analogue audio input for external
signals or digital via AVB. The system control and configuration shall
be done via RS 232, USB or Ethernet. The connection to a media
control system shall be possible. An integrated web service shall be
available for platform independent system configuration via
Smartphone, tablet PC or laptop/PC. The individual audio channels
shall be monitored via adjustable headphone connections with a
jog/shuttle button on the front. The OLED display shall indicate the
state and operation of all parameters. The connection on the front
shall be a plug-in type: 1x headphone output via 1/4" jack
(6.35mm); 1 x USB Type B. The connection on the rear shall be a
plug-in type: 1x bal. audio master output via 3-pin XLR; 1x bal. audio
master output via Phoenix terminal strip; 1x unbal. audio master
output via RCA; 4x bal. audio zone outputs via Phoenix terminal
strip, 1x digital AVB (Audio Video Bridging) via RJ45; 1x unbal. audio
input via RCA; 1x RS232 via 9-pin Sub-D; 1x TCP/IP via RJ45;
2x antenna connections N(HF). The dimensions of the 19" desktop
housing with 1 U shall be (WxHxD) 440 x 44 x 239 mm
[17.32" x 1.73" x 9.41"]. The delivery shall include 2 angled rod
antennas.

DESCRIPTION
The Quinta CU control unit is used to control about 150 wireless
microphone units with loudspeakers. Depending on the settings
and selected operating mode up to 4 microphone units can be
turned on simultaneously (e.g. 3 delegate and 1 chairman micro-
phone unit). There is a constant status inquiry, monitoring or
control due to the data connection to the microphone units.
Individual microphone units can be activated via the RS 232 serial
interface. The complete discussion system can be switched off via a
control command or by pressing the “Stand-by” button on the
front. The 4 LEDs on the front indicate the assigned transmission
channels of the microphones. For maximum security the control unit
can be protected with a PIN code accepting only microphone units
that have the correct PIN code. In addition to this, the radio
transmission is digitally encrypted.
The Quinta system meets the regulations of the European Tele-
communications Standards Institute (ETSI) and can be integrated
inot existing or new building computer networks that comply
IEEE 802.1 IT standard (AVB). For a safe wireless transmission there
are three frequency bands available: 2.4 / 5.2 / 5.8 GHz. The
switching of the channels is either automatically or manually.
The protection against unauthorised listening is guaranteed by using
128-bit encryption and a 24-bit PIN-code.
The integrated Web server allows configuring the control unit with
a Smartphone, tablet PC or PC via USB, LAN, WLAN.
The system can be connected to a media control system via the
RS 232 interface. This allows a particularly convenient operation and
provides different status indicators e.g. the battery status. Furthermore,
the Quinta system can be integrated into tele and video conferences.
