Subject: Re: Sound Devices Mix Pre limiter fault?

I've experienced no problems with my SD MixPre limiter. Is it
possible you have it set unreasonably low?
Glen Trew is especially complimentary of the MixPre limiter. (See:
/group/ /browse_thread/thread/b8d3120be057c87/f6a3b8428371ab72?lnk=gst&q=MixPre+limiter&rnum=2#f6a3b8428371ab72
)

Sound Devices is still at the AES Convention today (Booth 918). If
you're at or near NYC I'd recommend paying them a personal visit.
