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.

Microphone input impedance

HI: 1200 Ohm minimum

LO: 300 Ohm minimum
