A Diffrent 'Board But The Same Topic;
Last week I purchased a bog-standard Dynamic Microphone IMP.600 for the princely sum of £1.00 (US$1.88 at the time of writing). Plugged it straight into the back of the 6K and perfect sound quality. Even enough to record vocals as a WAV file ('board connected to PC).
Depending where you live you might not even have a PoundStore (i.e. everything costs £1.00) but if you have make use of it as their blank CD-Rs are excallent value.
(NB If there are any spelling problems in the above, forgive me but I only got up 5 minutes ago)
