Two Altec limiters have been on the bench recently for testing & refurbishment. I’ve recapped & modified both units and am hugely impressed with them – they’ve really exceeded my expectations
They seem to be typical of 70s industrial / installation gear with terminal strip i/o, balancing transformers and plugin preamps to match sources. I think a lot were installed in schools, churches & etc and were setup then left alone. They have two inputs – nominally one mic and one line input which are mixed together – and a switchable output limiter
