Live in Concert (STG Nov 96)

muzines.co.uk

The Allen & Heath GL4000 is a versatile and compact mixing console, impressively designed to handle front-of-house, monitor mixing, and multitrack recording roles with ease. Its adaptability makes it valuable for venues with changing requirements and limited budgets. Highlights include 8-group FOH or 12-bus monitor configurations, MIDI automation, and flexible channel sizes, expandable up to 48 channels. Despite its non-modular design, the GL4000 offers substantial flexibility with optional expanders and power supply choices. The EQ section is sophisticated, featuring a four-band sweep with switchable Q for mid-bands, a rare high-end touch. However, it might not appeal to users seeking a fully modular setup. Overall, it’s a robust and feature-rich option for those needing a compact, all-in-one solution.

At 2:34 in this video with Future Music Magazine, Ulrich talks about the GL4000 saying "I’ve been mixing stuff in the box for the last eight or nine years probably, and I always had a subjective feeling that the results weren't quite as good as the results that I used to have when I was still using a desk before that. I think the biggest problem is not even so much individual sounds, but when it comes to summing in the end, I always had the impression that the overall sound picture I was getting was lacking sort of detail and clarity and those details as well as separation and presence of individual elements. This summer I was working at a studio where I had the opportunity to use a desk again after a longer period of not doing it, and I just noticed that it wasn't just a subjective impression, I think actually objectively the summing is better in a desk, and that's why I decided to put one into the studio again."
