OUTPUT IMPEDANCE < 10Ω DC Coupled
ASP8024 Heritage Edition comes with a high-current reference headphone amplier provided
as the ALT3 monitor output destination. The new design features a 250mA high current output
stage based upon class leading Burr-Brown
TM
and LM4562 high-speed ampliers. The output is
entirely D.C coupled with very low output impedance for all types of headphones and there is
only one main capacitor in the signal path for very low distortion and sonic performance!
