[QUOTE="Christian Tepfer, post: 16142, member: 108"] Re: combined latency in IEM with 01v96 I just stumbled over 2 01V96, so here you are with the latencies: 01V96 analog channel in/Aux out 44.1kHz: 1.31ms 48kHz: 1.19ms 88.2kHz: 0.63ms 96kHz: 0.56ms (group out adds a little latency, not measurable, around .01ms) 01V96 analog in -> channel -> aux -> ADAT -> 01V96 channel -> aux out -> analog out 44.1kHz: 1.9ms 48k: 1.73ms 96kHz: 1.38ms 01V96 analog in -> channel -> aux -> analog -> 01V96 channel -> aux out -> analog out 44.1kHz: 2.6ms 48kHz: 2.4ms 96kHz: 1.15ms So what's interesting: the analog double conversion is faster than ADAT at higher sample rates, slower at lower rates. EDIT: a lot of people are using external A/D to raise the usable channel count. Be careful when using internal and external A/D, as there is a difference in latency: Focusrite @48kHz: 1.31ms internal A/D @48kHz: 1.19ms [/QUOTE]
