Heritage Audio HA-73 overview

  • 1Description

The Heritage Audio HA 73 is a 1 RU single-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 a three-stage discrete Class-A preamp, which utilizes stepped input gain and a -20 dB pad. Hand-wound Carnhill transformers impart color and character to the output.

Connect a mic or line input via balanced XLR jacks or hook up a guitar, bass, or keyboard to the integrated Hi-Z, JFET-based DI via the front-panel 1/4" jack. The selectable 82 Hz high-pass filter enables 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 73 ships with an external universal power supply for worry-free use anywhere in the world.
