Zero Distortion – less than one part per million

High output level +30dBu

Very low output impedance will drive long lines without interference or signal loss

True 48 volt phantom, polarity reverse & clip indicator

Separate XLR & 1/4” Phone (t-r-s) outputs, each with its own gain/level controls

1/4” phone connector output will drive balanced or unbalanced inputs

Full differential (balanced) from XLR in to XLR out – no internal conversion to single-ended

All discrete components; Class A amplification (no ICs in the signal path)

Greater transparency with minimum signal path and minimum features
