About Heritage Audio TT-73

An embodiment of superior audio technology, the TT-73 Tabletop Microphone Preamplifier is essentially a reimagined single-channel DMA73. This innovative product adds a unique dimension to the Heritage Audio's range of professional audio equipment, extending its applications to on-stage performances, portable audio systems, on-location recordings, and even hotel room setups.

Designed with the modern musician in mind, the TT-73 allows you to deliver 1073-driven line levels directly to front-of-house (FOH) engineers via the conveniently located front panel DI inputs. This feature enables musicians to maintain studio-quality recording levels, even when on the road or in non-traditional recording environments like hotel rooms.

One of the standout features of the TT-73 is its ability to elevate stage microphone signals to line level, eliminating the need for long cable runs. This is just a glimpse into the vast possibilities this preamplifier offers.

The TT-73 is also equipped with DI THRU jacks, a new addition to the range of tabletop units, facilitating simultaneous use of instrument amplifiers. To prevent any ground loops from introducing hum in the audio, a ground lift switch has been incorporated.

The TT-73 doesn't compromise on aesthetics either. The fusion of warm wood and RAF blue-gray steel gives this tabletop unit a distinctive look that stands out in any professional recording environment. It's more than just a piece of equipment; it's a statement piece that adds a touch of class to your semi-pro facility.

With its global internal power supply meticulously designed to prevent noise introduction, the TT-73 Tabletop Microphone Preamplifier is a testament to Heritage Audio's commitment to delivering high-quality, reliable, and versatile audio solutions.
