The second reason is for sonic shaping. All LaChapell Audio preamps place the -20dB pad function in such a way that, when engaged, the gain contribution from the input transformer is effectively eliminated. When that loss of gain is made up by dialing in INPUT gain, the user has essentially traded transformer gain with vacuum tube gain. As a result, the distortion is different, the frequency response is different, etc. User who use this this technique express hearing more “air” and “depth” to the sound. It’s not always preferred but it demonstrates the preamps sonic flexibility. A couple areas where this technique is routinely used are drum overheads and stereo piano overheads.
It’s been a LONG time coming, but it’s finally here. Version brings many noteworthy features and fixes. All known compatibility issues have been addressed for current users, and for those users that have been waiting patiently (or not), we’re finally fully consistent – all plugins are available 32 and 64 bit, both Mac and PC (with the exception of Psycho Dither which is still WIP and Microschope which has been retired due to lack of activity). The most exciting bit for new users, though, is additional platform support. We now support VST3 and (wait for it…) Pro Tools. Our plugins are available in RTAS (legacy), 32-bit AAX Native (Pro Tools 10), and 64-bit AAX Native (Pro Tools 11). Where appropriate, we have also built in support for Audiosuite (AS).
