gain before feedback issue, I bet it sounded phenomenal, for its time. [user]STEVETERRY[/user] was probably there, maybe he can tell us.
wall of sound" rigs circa 1973-74. It is important to understand that the concept was essentially a separate system for each source (in fact the bass was treated as four sources, one per string) and every speaker reproduced only one source. Being behind the band the system also served as the monitor system, letting the band hear the same mix the audience heard, in fact mixing was from on stage. Feedback was avoided by using a dual 'differential' mic approach where each vocal mic had a second identical mic attached to it that was wired out of polarity so that when the two were summed most of the system content was cancelled out. A good summary of the system is posted here, http://dozin.com/wallofsound/index.html
Before dismissing this system, realize that not only was this system very technically advanced at the time, but the concept of separating sources is also gaining new popularity. For the last Red Hot Chili Peppers tour, Dave Rat used a dual line array configuration that allowed assigning sources to either array, thus reducing the 'load' each array carried and providing increased clarity. For example, you're not asking a speaker or driver reproducing the vocals to at the same time reproduce the impact of a snare or crash and vice versa. So sometimes the idea that everything old is new again can also apply to technology.
Brad that system may be technically advanced for the time, and might sound very good........ But it would still give me nightmares to be an audio tech for that tour.
glad im not the only one thinking that, haha
looks like a great system for the era
house for years where the only things to eat were red meat and acid. The Dead eventually canned Owsly because the rig was such a tour nightmare. Him and his Altec Voice of theatre bins currently reside Australia because he suspects mass disaster in North America is upon us. An intense case of the crazies aside, I'm with MuseAV; the concept (setup aside) was bitchin'. The system removes the phase and headroom issues of a conventionally mixed PA, but if you've never taped a 57 to a 58 then this might be to old school for you to handle.
