AES50 in UseAES50 has been thoroughly proven on many high profile tours, live events and installations including:-Led Zeppelin (O2 Arena), Metallica,

AES50 – Key Attributes for Live SoundAES50 is ideally suited to Live Concert Sound applications, as it simultaneously provides:-• High Channel Count•

Low and Deterministic Latency Keeping transmission latency to an absolute minimum is critical with the increasedadoption of in-ear monitoring.• The de

AES50 Error Detection and CorrectionAES50 has two forms of error detection and correction:-•A Cyclic Redundancy Check (CRC) checksum is calculated at

AES50 ConnectionsAES50 uses the four pairs of Cat 5/5e cable as follows:-1 - Audio data transmit +2 - Audio data transmit –3 - Audio data receive +4 -
