IA504 R

IA504 is a half rack sized class-D power amplifier that can work both for constant voltage systems (70 or 100 Volts) as well as professional audio applications with 4 time 125 W 4 ohms, fit for stereo or bridge configuration. Two versions are available: both are equipped with onboard DSP, full range PSU with Power factor correction and a GPIO interface, but they differ on the networking side.

In facts, IA504R version comes with RDNet ports, and IA504D with Dante ports, able to embed remote control and digital audio-in.

RDNet
Digital net for bi-directional control of connected devices.
The acronym RDNet originates from the development, on behalf of RCF and dBTechnologies, of a universal network which allows adjustments in real time and supervision of all the connected systems, using cables based on ethernet cat 5 wires.
With the specific software and the interfaces control 2 and control 8, a complete command of the acoustic system will be possible allowing real time supervision on each electrical component of the various speakers.

RDNet allows you to

Monitor levels, limiters, and temperatures
Select system presets
Configure setups off-line
Mute units
Group modules and assigning group EQ, delay and phase  
Test individual components
Automatically address system components   
Tap into LAN and USB interfaces  
Extend the network via wireless LAN access points.
