Heritage Audio HA73X2 Elite

• Essentially a dual channel HA-73 Elite

• Made to the same specifications as the acclaimed ´73JR and DMA73 models.

• Industry standard Carnhill transformers hand wound in St Ives, England.

• 80dB, 3 stage fully discrete class A mic preamp.

• Line input on separate XLR for adding fat and warmth to prerecorded tracks.

• 20dB PAD on the mic input to avoid overloading the input transformer when desired.

• LOZ, switches the input impedance of the mic transformer from 200 to 50 ohm.

• 80 Hz hi pass filter. Fully discrete class A.

• Ultra high impedance, JFET based D.I.

• 1 Rack unit format.

• External universal power supply for worldwide use.
