Hello. Does anyone know why my audio levels drop significantly as soon as I start recording? Only recording 4 tracks of audio from a Tascam Portastudio. Get the levels perfectly set, press record, and all 4 tracks drop to -24 db or lower. Sometimes, without changing anything at all, after maybe 19 attempts, the volume level will suddenly play and record at the correct level. I can't be the only one having this issue. Greatly appreciate any solutions.
