D ESCRIPTION
• System check of all adjusted parameters
• Status check for error diagnosis
• Equalisation control for adjusting system’s audio response
• Audio input for balanced line-level signals such as wireless
receiver, mixing consoles, telephone hybrids etc.
• Unbalanced audio input for system extension
• Record output for direct connection to a recording system
• RS 232 interface allows the operation of the discussion system
via PC or other available media control systems such as AMX®,
Crestron®, Cue®etc. to enable complete conference room control.
•System configuration set-up options:
• Function of the microphone button
On/Off or PTT (Push-To-Talk, as long as the microphone
button is pressed, the microphone unit is switched on).
•Operation mode:
Request-to-Talk
This mode is only possible with an operator manually
controlling a PC or media control system (AMX®or
Crestron®). Pressing the microphone button on the
delegate unit the system registers a request-to-talk.
The operator has control over the next speaker using a
the PC or the console button.
Autonomy
Each participant can enable the microphone until the
maximum number of open microphones (NOM) is
achieved.
Override
Each selected microphone unit switches off the
previously activated microphone unit.
• The talk time of the delegates can be pre-set. After the
time has elapsed the microphone unit switches off.
• A flashing illuminated ring indicates the time when the
microphone is switched off. The flashing illuminated
ring can also be effected by an external control
command (AMX/Panja®, Crestron®).
•Chairman unit operational mode:
Normal
The chairman can switch on his microphone without
any limitation.
Mute
The priority button of the chairman's microphone unit
will mute all activated delegate microphone units.
When the priority button is released, all previously
selected microphones are re-activated.
Clear
The chairman can switch off all active delegate micro-
phone units using the priority button. They remain
switched off until the chairman switches off his micro-
phone unit by pressing the priority button.
• NOM (number of open microphones):
Defines the maximum number of delegate micro-
phones that can be switched on (up to 9 microphone
units).
• Muting the speaker:
When the microphone unit is switched on, it’s own
speaker is muted automatically. It is possible to mute
up to 10 other microphone units (usually the surrounding
units to reduce the possibility of acoustic feedback) as
soon as the speaker is activated.
A RCHITECT ’ S S PECIFICATIONS
Central control unit as main item of the discussion system with
conference media control. Integrated power supply unit and
processor for digital control of up to 32 microphone units. 2 multi-
function buttons and LC-Display with 2 lines/16 segments for
menu driven system operation and configuration. RS 232 interface
port on the front for system configuration with PC. System check
with error message after switching on the device. Master reset to
manufacturer’s default settings. RS 232 interface for operator’s PC
or external console. Two inputs for sound signals 250 mV
(balanced) and 1.55 V (unbalanced). The following three operation
modes can be chosen: Request-to-Talk (after request-to-talk the
chairman releases the microphone), Autonomy (each participant
can switch on and off his microphone unit), Override (each
switched on microphone unit switches off the previously activated
microphone unit). ”Next” function control (first in - first out) in the
Request-to-Talk mode. In each operation mode it is possible to
pre-set the talk time and warning time for each participant and for
the illuminated ring to indicate that talk time has elapsed. The
following parameters can be adjusted within the system configuration:
number and address of the chairman microphone units, function
of the priority button, number of the open microphones, number
and address of the loudspeakers to be muted in the microphone
units, input level of the signals and volume and sound control of
the master signal. 1 connection for microphone line. Recording
output (250 mV) and a 3-pin XLR socket for transformer balanced
line level output (+6 dBm). Recording output is independent from
the output volume adjustment. Desktop housing: 2 rack units high,
