2. DESCRIPTION
This conference system uses digital technologies according to the European Community's IEC914 and ISO
standards.
It is composed of a main unit and two microphone units – Delegate and Chairman – that feature high
sensitivity, a wide frequency response, an internal loudspeaker and a cardioid electret microphone with a
lighted ring for the visual identification of the microphone in use. The system is precabled to ensure fast and
easy installation.
The device may include up to 64 microphone units, daisy-chained on four independent lines (or a maximum
of 30 units on each line).
The system involves the use of several expansion units. Every expansion unit can support up to 60 units
divided on six lines (never use more than 30 units on each line).
Adding four expansion units, the system can control up to 254 units.
The serial connection of each unit is achieved through single multicore, prerouted cables that may be used
either for fixed or mobile systems.
Main Functions:
It directly powers and controls 64 microphone units.
Chairman unit has priority on others.
Three operating modes: FREE MODE, LIMIT MODE and FIFO MODE
Microphone sensitivity level control.
Built-in video processor to support video camera tracking
Product complies with CE regulations

6. INSTALLATION AND CONNECTION
Connect the unit to 230 V AC 50/60 Hz mains. Use the connection cables provided to connect the daisy-
chained microphone units to the 4 Delegates outputs, paying attention not to connect more than 30
microphones units to each line and no more than 64 microphone units altogether.
The configuration cannot allow more than 30 microphone units on each loop.
In any case, the maximum limit of 64 microphone units cannot be exceeded.
The system can host more than one Chairman microphone. They can be inserted at any position on the
chain.
1- Prepare conference controller, chairman microphone, delegate microphone, main extension cable
and microphone branch cable (Y type)
- The controller is supplied with a main extension cable (13 m with one male DIN-8 connector for
connection to the controller, one female DIN-8 connector for connection to the microphone Y type
branch cable), one male-female XLR cable, one RCA-6.3 mm jack audio cable and one power
cable
13 m
- Chairman microphone and delegate microphone are supplied with a branch/interconnection Y
type cable (2+1.5 meters) with one female DIN-8 connector for connection to the main extension
cable or to the previous microphone, 2 male DIN-8 connector for connection to microphone and
extend the line to the next microphone
2Connect the main extension cable (male DIN-8 13 m) to one of the sockets group (DELEGATES)
of the controller. In each of the 4 lines you can connect 30 mics maximum. Connect the other end
of the extension cable (female DIN-8 13 m) to Y type microphone branch cable (male DIN-8 2 m),
connect the chairman or delegate microphone to the Y type microphone branch cable (male DIN-8
1.5 m), and the male DIN-8 connector to the next Y type microphone branch cable (female DIN-8
2m) to extend the microphones
Note: Paying attention not to connect more than 30 microphones units to each line and no more than
64 microphone units altogether, microphone quantity in one system may decreased according to
different microphone type and cable length.
3If desired, contact any of the line-level outputs (balanced XLR or unbalanced RCA) to the input of
an amplifier.
4Connect the controller to 230 V AC 50/60 Hz mains by power cable.
5To talk on a microphone, please press the on/off key. When you finish talking, turn off the
microphone by pressing the key again. If microphone is active, indicator light switches on.
6When chairman press and hold the PRIOR key 1 second on chairman microphone unit, all active
delegate microphones will be switched off and the chairman microphone will active.

7. HOW TO USE THE SYSTEM
Turn on controller, the controller LCD will display current working mode
MODES OF OPERATION:
FREE MODE
When this mode is selected, the display will read FREE MODE. In this mode, an unlimited number of
participants can speak simultaneously.
LIMIT MODE
When this mode is selected, this display will show LIMIT MODE, plus the number of delegates that
can speak simultaneously. Once this number of delegates is reached, no further delegates will be
allowed to intervene until the number of active delegate units again falls below this limit.
FIFO MODE
When this mode is selected, the display will read FIFO MODE (First In-First Out), plus the number of
delegates who can speak simultaneously. In this mode, the controller keeps track of the order in which
the delegate units are activated. Once the preset limit of simultaneous delegates has been reached,
and a new delegate presses the MIC ON/OFF key on his microphone base, the FIRST delegate unit
that was active when this limit was reached will be made inactive, and the new delegate unit will be
activated.

12
Activation and Deactivation of previous Operating Modes
Using the MODE button, select the desired operating mode and press SAVE. If the mode requires a numeric
limit of delegates, this can be selected pressing the NUMBER button and pressing SAVE to complete the
setup.
FUNCTIONS:
C. ONLY MODE
When this function is activated, the display will show “C.ONLY MODE” followed by the check mark “√”.
When deactivated, the display will show “X” beside this function.
C.ONLY MODE √:
When the CHAIRMAN presses the PRIORITY key, all DELEGATES will be excluded, and the
DELEGATE microphones will not reactivate when their MIC ON/OFF key is pressed. These will
remain excluded until the CHAIRMAN again presses the MIC ON/OFF key.
C.ONLY MODE X:
When the CHAIRMAN presses the PRIORITY key, all DELEGATES will be excluded, but the
DELEGATE microphones will be reactivated normally when their MIC ON/OFF keys are pushed.
In either case (C.ONLY MODE “√” or “X”), the number of DELEGATES who can speak simultaneously
will be determined by the previously selected limit.
A. OFF MODE
When this function is activated, the display will read A.OFF MODE followed by the check mark “√”.
When deactivated, the display will show “X” beside this function.
A.OFF MODE √:
All activated DELEGATE units will be automatically disactivated after 45 seconds of inactivity. In
order to speak again the delegate will have to press MIC ON/OFF again
A.OFF MODE X:
There are no time limits for the activated DELEGATE bases
This function does not affect the CHAIRMAN unit
AUTO CODING
Each mic has a number ID which is affected (very important to setup the auto-track and voting function)
Controller:
- The controller starts the setup of the mic code by turn on the controller+ hold and press Number
button
- For that, use the buttons MODE and Number to select the start number, once the selected start
number, press SAVE button, operator can start coding, usually system setup the code from 1
- In general, you assign number 1 to the chairman mic.
- The first setting code will transmitted to all the delegate mic.
.
Microphone:
- This coding information is displayed on all the microphone LCD, press the on/off button of the
corresponding mic to the affected the number.
- The other mics are always show the coding information but with an incremented number of a unit.
- All mic LED will start flash during setup code, the LED will off after setup code.
- Please restart the system to save the system code setup of mic
Activation/Deactivation of functions
Select a function using the scroll button MODE and activate/disactivate pressing the NUMBER button
