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
