>>Peter, write to us about "A" scales and "B" scales. ---------- If I might be permitted to jump in here, IIRC the "A" scale has the dB on top and the 0-100+% on the bottom, used more for recording. The "B" scale has percent on top (for mod monitors and suchlike broadcast use) with the dB scale on the bottom. Glen Kippel KHCS Palm Desert, CA
