How does MIKEY Digital compare to the other audio recording accessories on the market?MIKEY Digital is the only accessory that has both a built-in microphone & 1/8 inch (3.5mm) line-in jack. It also has very high quality microphone capsules & Blue's decades of microphone design experience, resulting in the best recording quality. Is it possible to record with the microphone & line-in at the same time? No. How does MIKEY Digital compare to my built-in microphone? There are numerous advantages-- can record in stereo, whereas others can only record in mono higher fidelity, sound quality-- the analog mics rely on the built-in A-D converter & circuitry, whereas MIKEY Digital uses Blue's discreet preamplifier, processing, & A-D conversion higher SPL handling (built-ins & cheap mics can only go to ~100d B, MIKEY digital can go to ~130d B) automatic gain-- MIKEY Digital can adjust to a wide range of recording situations, built-ins have no flexibility adjustability-- built-ins & simple plug-in mics don't have electronics or sophistication so there's no control over the mic or input flexibility-- MIKEY Digital can record directly or take a wide range of inputs How does the automatic gain control/versatile input work? Those usually don't sound good... Blue utilized a powerful processor which constantly analyzes the sound & tracks the change in sound volume over a long periods of time, so it is able to make better decisions around when to change the sensitivity. Similarly, the processor tracks the versatile input to analyze the load & voltage level of what is plugged into it, & adjusts accordingly to the best sound quality. Is the line-in on MIKEY Digital stereo? Yes. Stereo, if mono signal is present it will dupe the mono signal to both stereo channels.
