APPENDIX II: RHAON Block Diagrams
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 loudspeaker
control and monitoring. Notice that the wiring loops from loudspeaker to loudspeaker just as it does in analog distribution. 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 AES/EBU inputs on all Iconyx amplifiers and on PM-R series amplifiers are fully balanced 110 Ohm inputs and are equipped with
a balanced loop through to the next array. Their AES/EBU interface automatically detects the source sampling frequency, locks onto that
sample rate whether it is 44.1 kHz, 48 kHz or 96 kHz and converts it to 48 kHz. As a result it is not necessary to re-initialize the system
when running from AES/EBU sources having different sample rates as long as the amplifier is operating with a 48 kHz sample rate. If the
amplifiers(s) are set up for 96 kHz operation, then the source sampling frequency must also be set to 96 kHz.
