Two channels of rich, thick 73 preamp sound in one 1U rack unit. The Heritage Audio HA73X2 Elite is a dual-channel microphone preamp built to the same specifications as Heritage Audio’s 73 JR II and DMA 73 – the exact equivalent of two HA73 Elite channels. Modern production methods are used, while key vintage parts are kept, like Carnhill transformers hand-wound in St Ives, England.
Why customers choose it
Who it is for
Home and project studios, singers, guitarists and bass players, engineers recording stereo sources or two sources at once, and anyone who wants a real 73-style preamp for vocals, guitars, bass, drums and more.
