When you hit the dead spot on the pots, the meter still shows signal leading you into a trap of thinking you've got signal, but nothing is recorded?
Not sure what you're saying here. When you hit the dead spot, the meter shows no signal because the channel has turned off, and you're recording silence. If it was showing signal, that means you're not at the dead spot.
It might also be worth pointing out in the FAQ that before upgrading the firmware, the higher gain range may not be appropriate for rockNroll with high gain mics based on some user experience.
Maybe, but I think before everyone has a total cow about this, someone else needs to verify my measurements and make sure my numbers are accurate. As I said, those lower limits are not
official, and are what I figured out through my own testing. My basic math skills are known to be rather suspect at times.
The dead zone on the pots is a huge annoyance. Again, everyone here needs to email Tascam customer support if they want to see any chance of this or other issues fixed.
If I had my way, I'd keep the 4 gain levels they went to in the newer firmwares, but lower them all by 10dB, making the max gain of the unit +53dB. And this is coming from a classical recording person. I say this for two reasons:
1. Once you get halfway through HIGH+, it's far too noisy to use for much of anything. Jim Williams said on GS that that's when the input transistor noise dominates.
2. Anyone that truly needs +63dB of gain is probably doing so with a professional piece of equipment from Sound Devices, Zaxcom, Aeta, Nagra, Millenia, Benchmark, etc.
