HA73X2 - Dual Channel 1073 Mic Preamp
The Heritage Audio ELITE series is a budget-friendly version of the widely respected, hand-wired 73JR and DMA73 preamps. A combination of mass production, lean manufacturing and modern construction techniques makes it possible to offer a zero compromise, high quality yet very affordable series of products.
The dual channel HA73X2 ELITE microphone preamplifier is based on the iconic 1073, amplifying any microphone or instrument with vibrant clarity and punch. On driving the input harder it provides the saturated sound as known from a vintage console. With 80dB of gain the HA73X2 is suitable for any type of microphone - condenser, dynamic, or ribbon. The hand wounded Carnhill input and output transformers add warmth, girth, and authority to any sound source - mic, line, or even DI instruments. The separate input and output gain controls make it easy to control the transformer color without overloading the output stage. The DI circuit is ahead of the mic input transformer, perfect for adding some character to DI bass signals on the way in. The HA73X2 offers two channels of classic sound in one rack unit for stereo recordings or two single sources.
