Just thought I'd mention that I've been using the SPL MTC 2381, Monitor Talkback Controller for a year now and it is excellent. I'm really happy I bought it and highly recommend it. It does exactly what its supposed to do and the sound quality is excellent."Stereo volume, source and monitor control with cue mixing and talkback functions" The way its designed in so logical. Perfect for engineers migrating from the old analog console to a DAW and wondering WT.... , where is the monitor knob! It sits at the perfect angle at my desk, very well thought out. Two thumbs up on this. Thanks for recommending it Paul! http://www.spl.info Cheers!
