Description

Zone selection (Z1 to Z4) on each channel for multiple or individual broadcasting
Volume equalizer for each channel
Volume control and vumeter for each output
Exit monitoring for each zone
Inter ON/OFF phantom powering on microphone inputs

Option Microphone consoles :

The PTT 100N console is equipped with switchable chime, siren and priority functions. When the "Talk" button is pressed, the message is broadcast simultaneously in all zones. Three 100N PTT stations can be connected. The lectern is connected to the preamplifier via RJ45/Cat.5 socket (3m cable included).

The RM-400 Microphone Keypad provides remote control. The priority and chime function can be activated or deactivated. Equipped with switches to address the message to one, several or all zones. Up to 32 RM-400 stations can be addressed and connected in series up to 1.2 km long. The connection is made via CAT5 cable with RJ45 plugs.

Input terminal for announcements (Inter selection Link for announcements on each zone)
Local input terminal block (Inter selection Link for emergency message on each zone) (use of announcement or local signal, interception of the signal for the main unit)
PTT micro console input terminal block for emergency announcements (RJ45 socket)
Type: RS-485, max. distance 1.2 km
Detector circuit for reducing consumption in stand-by mode or when the amplifier does not receive a signal
The device can be operated in emergency mode on DC 24V.
