Warm Audio WA73: The Ultimate Analog Front-End
The Warm Audio WA73 is designed for producers and engineers who want to transcend the flat sound of standard interface preamps. This unit is an accurate tribute to the legendary 1073, a device that has been the definition of “big” sounding recordings for decades. Whether you’re working on vocals, drums or guitars, the WA73 gives your signal the body and texture it needs to fit right into the mix.
Custom CineMag USA Transformers
A ’73-style preamp is all about the transformers. Warm Audio has worked closely with CineMag USA to develop components that precisely mimic the harmonic complexity of vintage British hardware. When you run the input-gain “hot” and lower the output volume, your sound takes on a wonderful analog saturation that instantly adds character to your recordings.
Versatility and Control
The WA73 is more than just a microphone amplifier:
80 dB Gain: With an impressive gain reserve of 80 dB, you get a crystal clear and powerful signal from even the most insensitive microphones (such as ribbon mics).
Tone switch: Change the input impedance to subtly adjust the character of your microphone.
Hi-Z Instrument Input: The front instrument input makes the WA73 a great DI for bass guitars and synthesizers.
High-Pass Filter: An inductor-based filter (adjustable at 50, 80, 160 or 300 Hz) helps eliminate unwanted low-frequency rumble right at the source.
Professional Workflow
The WA73 is built for intensive studio use. The stepped gain control ensures that you can always reproduce settings exactly(recall), which is essential for professional sessions. With its rugged 19-inch housing, this is the perfect upgrade for any rack.
