PPM8-G2
Table top microphone consoles for commercial use

PPM8

PPM8 is a uni-directional addressable condenser paging microphone compatible with IDA8 and DIVA8 systems. PPM8 uses RS485 protocol over a single CAT-5 cable connection to transport both audio and power from the paging console to the system units. The PPM8 has 8 zone buttons with a sleek gooseneck microphone, providing both durability and aesthetics in a slim, stable chassis.
 
The PPM8 enables live announcement to any pre-assigned zones (an optional SP version also allows broadcast of pre-recorded messages). The paging station has a gooseneck microphone, a push-to-talk button, zone selection keys and a monitor speaker. Buttons can represent a single zone or a group of zones and are easily defined in the software using a simple matrix selection.
 
All buttons can be programmed with drag & drop features from the software and each button can be programmed for PTT (Push To Talk) or latching functionality.
In addition to the zone LEDs, “Hold” and “Busy” LED signals make this an extremely user-friendly paging console.
 
The uni-directional condenser microphone ensures high-quality directive signal pick-up from the user with minimal interference from the surroundings thanks to the cardioid polar pick-up pattern. In accordance with BS5839, the PPM8
is monitored on RS485.
 
The RS485 communication protocol allows daisy-chaining up to 300m on a single CAT-5 cable (FTP/STP) and makes each station easy to connect using standard RJ45 connectors and the junction connection box (supplied with PPM8).
If Power over Ethernet is not available, or the CAT-5 cable is over 50m long, the console can be powered locally with a 24 VDC supply.
 
Note:
There are two versions of the PPM8 paging console with identical hardware and functionality but different firmware for compatibility with different systems.
 
PPM8-AS: Used with IDA8 system and ECS system controllers and slaves
PPM8-G2: Used with DIVA8 system controllers
