Heritage Audio TT-73 Tabletop Microphone Preamp

Heritage Audio TT-73 Desktop Microphone Preamp: Vintage Sound in a Portable Package
The Heritage Audio TT-73 Desktop Microphone Preamp is a one-channel, portable preamp that delivers the legendary sound of the Neve 1073 in a compact, rugged form. Designed to provide the rich, punchy, and vibrant sound that made the 1073 famous, the TT-73 offers all-discrete, Class A electronics that are faithful to the original vintage Neve 80 Series console preamps. Whether you're in the studio or on the go, the TT-73 gives you the flexibility to achieve that classic, in-your-face sound, with the same warmth and character that has made the Neve 1073 a sought-after piece of gear for decades.

Portability Meets Legendary Neve Sound
For musicians and engineers who want the iconic Neve sound on the road, the TT-73 is the perfect solution. With its lightweight, portable form factor, it’s easy to take anywhere—from hotel rooms to live performances—while still maintaining the high-quality sound you expect from Heritage Audio. The “TT” in its name stands for Table Top, indicating that this preamp is not only studio-worthy but also designed for mobile use. With a convenient handle and the same tonal warmth of the original 1073, the TT-73 is perfect for recording or amplifying instruments in various environments, including live settings, remote locations, or small studios.

80dB Mic Pre and 50dB Line Pre for Versatility
The TT-73 offers an 80dB Class A microphone preamplifier and a 50dB Class A line preamplifier, providing a wide range of gain options to suit any audio source. With its high-gain positions and selectable input impedance, the TT-73 is particularly well-suited for ribbon mics, offering the optimal high impedance for older models. The line preamp features bridging input impedance, ensuring clean signal transfer, and the unit’s all-discrete design minimizes distortion, giving you a pure, vibrant sound. Whether you’re tracking vocals, guitars, or other instruments, the TT-73 ensures your recordings stay full of life and presence.

Flexible Direct Input for Multiple Uses
One of the standout features of the TT-73 is its ultra-high impedance J-Fet Direct Input (DI), which is built into the front panel and is connected to a high-quality Neutrik jack. This DI input allows you to connect instruments directly to the preamp, bypassing the mic input, and delivering clean line levels to front-of-house or recording systems. The DI circuit is positioned before the mic input transformer, ensuring it remains active when in DI mode. Additionally, the DI Thru jack features a ground lift switch, allowing for simultaneous, hum-free use of instrument amplifiers. This flexibility makes the TT-73 an excellent tool for both studio and live sound environments.

Premium Components for Superior Sound
The TT-73 is built with the same attention to detail and premium components that Heritage Audio is known for. It features Carnhill input and output transformers, which are crucial for providing the distinct warmth and punch that vintage Neve gear is known for. The 80Hz highpass filter, a third-order Bessel filter with an 18dB/octave slope, ensures that low-end rumble is eliminated without affecting the musicality of your recording. The preamp also features gold-plated Neutrik XLR connectors, ensuring that every connection remains clean and secure, while the custom-designed PSU accepts worldwide voltages, making it an ideal choice for traveling engineers and musicians.
