trying to get some insightful opinions on this, and possibly some education:

....for running instruments from a Sansamp (1/4" out) into a 737, would you recommend the instrument input (front panel 1/4", unbalanced); or into the rear panel xlr balanced line input (using 1/4" out - from sansamp - to xlr cable - into 737 - ?)

I suppose the sansamp is an unbalanced output, but does it bring the signal to line level (for which the Avalon's line input would make sense) or is this still considered an unbalanced instrument level that should go into the front of the 737?

thanks for any advice on differentiating between these two signals
