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 – H-7300 – and two microphone units – Delegate (H-7800d) and President (H7800c) – 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 stations, daisy-chained on four independent lines (or a
maximum of 30 stations on each line).
The system involves the use of several expansion units – H-08EX. Every expansion unit can support up to
60 stations divided on six lines (never use more than 30 stations on each line).
Adding four expansion units, the system can control up to 254 stations.
The serial connection of each station 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 stations.
President station has priority on others.
Three operating modes: FREE MODE, LIMIT MODE and FIFO MODE
One microphone input (MIC) and one line input (LINE) for external units.
TAPE output for recordings and line output (LINE) for amplification (balanced and unbalanced).
It allows insertion of an audio processor to the chain.
Microphone sensitivity level control.
Loudspeaker level control for the unit monitors
Support video camera tracking and voting function
Product complies with CE regulations

Connect the unit to 230 V AC 50/60 Hz mains . Use the connection cables provided to connect the daisychained stations to the 4 BASE INPUTs (figure 2, ref. 23) as shown in figure 5, paying attention not to
connect more than 30 stations to each line and no more than 64 stations altogether.
Closed-loop lines can be created with the optional 3 m cable, as shown in figure 6. In this way no station
will be isolated in case of interruption one of the lines. The configuration shown in figure 6 cannot allow more
than 30 stations on each loop.
In any case, the maximum limit of 64 stations cannot be exceeded.
The system can host more than one PRESIDENT station. They can be inserted at any position on the chain.
If the system should support video camera track the conference management function, please connect the
system as per figure 7.

7. HOW TO USE THE SYSTEM
Turn on H-7300, the controller LCD will display current working mode (fig1. ref.5)
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 stations 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 H-7300 keeps track of the order in which
the delegate stations are activated. Once the preset limit of simultaneous delegates has been reached,
and a new delegate presses the MIC ON/OFF key (fig. 3 ref. 5) on his microphone base, the FIRST
station that was active when this limit was reached will be made inactive, and the new delegate station
will be activated.
Activation and Deactivation of previous Operating Modes
Using the MODE button (fig. 1 ref. 2), select the desired operating mode and press SAVE (fig. 1, ref. 4). If
the mode requires a numeric limit of delegates, this can be selected pressing the SET button (fig. 1, ref. 3)
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 PRESIDENT presses the PRIORITY key (fig. 3, ref. 6), 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 PRESIDENT again presses the MIC ON/OFF key.
C.ONLY MODE X:
When the PRESIDENT presses the PRIORITY key (fig. 3, ref. 6), 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 stations will be automatically disactivated after 45 seconds of inactivity.
In order to speak again the delegate will have to press MIC ON/OFF again (fig. 3, ref. 5)
A.OFF MODE X:
There are no time limits for the activated DELEGATE bases
This function does not affect the PRESIDENT base
Page 14

MUSIC MODE
When this function is activated the display will read MUSIC MODE followed by the check mark “√”.
When deactivated, the display will show “X” beside this function.”
MUSIC MODE √:
When the PRESIDENT presses the PRIORITY button (fig. 3, ref. 6), the DELEGATE speaker
monitors will reproduce a warning tone.
MUSIC MODE X:
When the PRESIDENT presses the PRIORITY button (fig. 3, ref. 6), the DELEGATE speaker
monitor will not produce a warning tone
Activation/Deactivation of functions

There are three buttons on the microphone unit for voting: yes/abstain/no. After voting starts, delegate
can press the corresponding button according to their willing. The delegate can re-vote before the
voting finishing if they want to revise their vote; the voting results are subject to last key-press. The
voting results will display in the LCD.
ELECT
There are five buttons on the microphone unit for electing: Candidate 1/2/3/4/5. After election starts,
delegate can press the corresponding button according to their willing. The delegate can re-elect before
the election finishing if they want to revise their elect; the election results are subject to last key-press.
