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.
Two versions available:
IA504R version comes with RDNet ports
IA504D with Dante ports, able to embed remote control and digital audio-in.
