Subject: [Drakelist] R4C Speaker Output
Hi Group On the R4C speaker output which is 3.2 ohms. Can
this audio be attached to a computer's microphone jack
(typically 50K) using a resistor pad to prevent overload??

Short answer is yes. I would make a simple pad with a 4
ohm resistor across the output and a high value resistor or
pot feeding the computer line. The resistor across the
output will insure the amplifier is seeing something like
the right load which will give best frequency responce and
minimum distortion. OTOH, the headphone jack is fed from
the same place as the speaker jack and will feed phones of
almost any impedance so its probably not very critical. If
your computer has a "line" input you might try that as well.
