Transformer isolated D.I. box that is very versatile and intended for use in the studio and on stage. Unlike standard D.I. boxes, it can accept virtually any input connection and level (including amplifier speaker outputs). Switchable input level handles instrument and Hi-Z buffer out, while switchable FET active circuit ensures an ultra-low noise floor. The unit features an oversized nickel audio transformer with very high quality, switchable ground lift and 6.3mm parallel output and unbalanced buffered output. It can be powered by 48V phantom power or 9V DC.
