I recently bought a Presonus Audiobox USB interface. Two inputs, which are a universal XLR / 1/4" type. I had planned on using it both with two microphones and also with a small 8 channel mixer, plugging the line level outputs of the mixer into the inputs of the interface to do some live 2 channel recording.
Now that I've actually read the manual (note to self: always download and read the manual before buying) it seems to say that these inputs are for microphones or guitars ONLY, not line level devices such as mixers or keyboards. The specific text:
Instrument Inputs (Channels 1 and 2). The TS connector on channels 1 and 2 are for
use with an instrument (guitar, bass, etc.). When an instrument is plugged into the
instrument input, the mic preamp is bypassed, and the AudioBox USB becomes an active
instrument preamplifier.
NOTE: Active instruments are those that have an internal preamp or a line level output.
Active instruments should be plugged into a line input rather than into an instrument input.
Plugging a line level source into the instrument inputs on the front of the AudioBox USB
not only risks damage to these inputs but also results in a very loud and often distorted
audio signal.
(In other words, don’t plug a line level source into the combo jacks of channel 1 or 2.)
Needless to say this sucks, and it looks like I wasted some cash. I was wondering if anyone here had tried using a mixer or keyboard or other such device in their Audiobox USB?
