Heritage Audio HA-73X2 overview

  • 1Description

The Heritage Audio HA 73X2 is a 1 RU dual-channel Elite Series microphone preamplifier designed to provide the sound of classic Neve 1073 preamps for recording engineers, musicians, and vocalists in mobile-recording rigs and home, project, and commercial studios. It features 80 dB of gain via three-stage discrete Class-A preamps, which utilize stepped input gain and -20 dB pads. Hand-wound Carnhill transformers impart color and character to the output.

Connect mic or line inputs via balanced XLR jacks or hook up instruments to the integrated Hi-Z, JFET-based DIs via the front-panel 1/4" jacks. The selectable 82 Hz high-pass filters enable quick low-end management when rumble or proximity effect needs to be attenuated. Phantom power and input impedance are selectable and the output level is continuously variable.

The HA 73X2 ships with an external universal power supply for worry-free use anywhere in the world.
