Based on the legendary 1073, the two-channel Heritage Audio HA73X2 ELITE microphone preamplifier delivers vivid clarity and pressure to any microphone or instrument, and with up to 80 dB gain, the HA73X2 can be used with any type of microphone, from condenser to dynamic to ribbon microphones. Carnhill's hand-wound input and output transformers give any source, whether microphone, line or DI instrument signal, warmth, richness and assertiveness. The separate gain controls for the inputs and outputs allow the signal to be selectively colored by the transformers without overloading the output stage. The DI circuit is located in front of the transformer of the microphone input: This preserves the specific character of a fed-in bass DI signal. The HA73X2 offers two channels with classic sound characteristics on one treble unit for stereo recordings or two individual signals.
