PERTAMAXBET 0-3 Preamble A synchronisation preamble (biphase mark code violation) for audio blocks, frames, and subframes. Each audio sample (of up to 24 bits) is combined with four flag bits and a synchronisation preamble which is four time slots long to make a subframe of 32 time slots. 4-7 Auxiliary sample (optional) A low-quality auxiliary channel used as specified in the channel status word, notably for producer talkback or recording studio-to-studio communication. 8-27, or 4-27 Audio sample One sample stored with most significant bit (MSB) last. Each bit occupies one time slot. No attempt was made to use a carrier able to support both rates; instead, AES3 allows the data to be run at any rate, and encoding the clock and the data together using biphase mark code (BMC).|He was Replaced by Sean Pierson
