We’re moving to a two-channel backup for Zoom-heavy calendars and I want a setup our whole crew can mirror. Current test is a Tascam DR-10L at 24‑bit/48 kHz on the witness plus Case CATalyst Audiosync on the laptop, naming like 2025-10-22_Smith_v_Jones_Rm3, with a QA goal of sub‑30‑second clip retrieval — any tips on gain/limiter settings or alternate recorders (MixPre-3, H1n) that have held up in real proceedings?
On my DR‑10L I enable dual‑record for a safety track, low‑cut at 80 Hz, limiter on, and set gain so normal speech peaks around −12 dBFS; that’s kept witness tracks clean while still giving me a belt‑and‑suspenders buffer. If you go MixPre‑3 II as the room backup, 32‑bit float with limiters off rides out Zoom shout‑laughs but bloats files, and adding the start time to the filename (e.g., 2025‑10‑22_0930) makes “sub‑30‑second” pulls quicker in Case CATalyst.
For sub‑30s pulls, sync clocks before roll: set the DR‑10L’s date/time and NTP‑sync the laptop, then slate “Smith v Jones, Rm3, witness” at start so timestamps line up and retrieval’s a jump, not a scavenger hunt. If you need a swap, MixPre‑3 II’s 32‑bit float is forgiving on surprises; H1n works but its lav input is hissy and that gain slider loves to get bumped, @lambert_f45.
