I'm the proud owner of a Tascam DR-2d and a CA-9100 Church Audio preamp.
I've read on another thread that the CA-9100 can add up to +20dB gain when cranked to the max.
On the other hand, I couldn't find any information on how much gain can be added from the Tascam recorder itself (mic-in and/or line-in) when starting from 0 and cranking up to 100.
I recorded two shows recently and the first one came out with very low levels while the second one came out slightly distorted.
I've changed the setups on both the Tascam and the CA preamp for the second recording, but not much enough to suspect I'd get such a gap in gain between the two.
Both concerts were pretty similar in SPLs (same venue, same spot, same sound engineer, same kind of music).
1st recording :
CA-9100 (gain @ ~11 o'clock) > Tascam DR-2d (line-in - levels @ 96/100). Peak at ~ -20dB
2nd recording :
CA-9100 (gain @ ~12 o'clock) > Tascam DR-2d (line-in - levels @ 100/100). Sound was slightly distorted at loudest parts...
So there's more than 20dB gap between the two setups for +4/100 gain on the Tascam and +1(hour) gain on the CA preamp.
How can this be possible ? Is the preamp multiplying instead of adding gain to the recorder value ?
Thanks !
