I need a small, simple preamp to tailor the output of a standard
electret mic, to limit the bandwidth to approximately a telephone, say
300 - 3400 Hz and with fairly sharp cutoff.
Must be available quickly, I haven't time to design and build. If the
project works I will need several.
Most simple off-the-shelf preamps do not have tone controls, or are
large and unnecessarily complex for my purpose. Google hasn't been my
friend so far.
Any ideas?
Thanks.
