Serial Digital (AES3) aka AES/EBU
The block diagram below shows a RHAON system using digital audio distribution in the AES3 format along with RHAON loudspeak-
er control and monitoring. Notice that the wiring daisy chains from loudspeaker to loudspeaker. The digital audio distribution line is
conventional twisted pair shielded digital audio cable, Beldon 1800B or 1800F or equivalent.
Notes
1. In this system, RHAON and the Ethernet network are being used only for loudspeaker control and monitoring.
2. Neither CobraNet digital audio distribution nor analog audio distribution are available when AES3 format digital audio distribution is
being used; the AES3 format audio channels occupy the amplifier’s analog input channels.
3. The AES3 inputs on RHAON empowered PN1, PF1 and PF2 loudspeaker amplifiers are high impedance to allow daisy chain con-
nection. The last unit in the loudspeaker chain should be terminated with a 110 Ohm resistor. Systems having Iconyx, IC Live and
PM series amplifiers do not need the termination resistor.
4. The distribution line shield in systems having PN1, PF1 and PF2 amplifiers should be connected only to the AES3 source device.
It should not be connected to the amplifiers, but instead should be telescoped around the amplifier.
5. In RHAON ccontrolled systems having PN1, PF1 and PF2 amplifiers the AES33 clock and the CobraNet/RHAON clock need to be
synchronized. Most AES32 sources allow for synchronous operation with CobraNet. For best results, connect the RHAON network
first, then connect the CobraNet synchonized AES3 source and then individually switch the loudspeakers to AES/EBU mode.
