A friend of mine is looking for a good front end for his speech sampling A/D converter. What is needed is an amplifier for microphone input with a good LP-filter built in with fixed/variable cutoff frequency in the 5 kHz area. The output can be in the 100mV to 10V range. Isn't anyone out there that can recommend such a box? -- Heimir Thor Sverrisson heimir@rhi.hi.is
