Warm Audio WA-MPX

Warm Audio WA-MPX tube preamplifier: Authentic vintage sound for modern studios

The Warm Audio WA-MPX is an exact replica of one of the most revered tube microphone preamps that shaped the rock 'n' roll era. This device brings back to life the classic sound of the band era, heard on recordings by icons such as Elvis Presley, Les Paul and Bing Crosby. The WA-MPX combines high-quality components, a detailed circuit design and the ability to add tape saturation to create a warm and analog sound that meets the demands of today's artists. Combining traditional tube technology with modern features, the WA-MPX is the perfect tool to give recordings the warm, saturated sound of decades past.

Warm Audio: Reliable reproductions of legendary audio devices

Warm Audio is renowned for its authentic reproductions of classic studio equipment and offers musicians and sound engineers access to legendary sounds at affordable prices. The WA-MPX tube preamplifier fully embodies this principle and delivers the characteristic analog sound that can be heard on countless hit recordings from the 50s to the 70s. The combination of handcrafted circuitry and high-quality components, such as specially wound CineMag transformers and vintage tubes, ensures that the WA-MPX captures the essence of the original both sonically and visually.

Handcrafted circuit design for ultimate analog sound

The WA-MPX is completely discrete and hand-built, with a three-tube circuit per channel that offers the typical warm and full sound character of a tube preamp. The tube combination of two 12AX7 and one 12AU7 vacuum tube provides harmonic distortion and natural compression, making the sound more lively and colorful. The tube is used as an amplifier stage and produces a rich, analog timbre that creates a natural and detailed sound, especially with vocals and instruments with low frequencies.

Authentic tape saturation for analog sound

A highlight of the WA-MPX is the switchable Tape Saturation control, which emulates the harmonic distortion and natural compression of an analog tape recorder. This tape saturation gives the sound additional warmth and fullness and makes the sound particularly present and assertive in the mix. The harmonic overtones created by the saturation add a subtle distortion that creates an authentic vintage sound quality, especially on guitars, bass and vocals.

90 dB analog tube amplification for maximum flexibility

With up to 90 dB of tube gain, the WA-MPX offers exceptional performance for all types of microphones, including those with low output levels or with quiet sound sources. The high-gain switch activates a third tube in the circuit, providing an additional 20 dB of gain. This is particularly beneficial for recording acoustic instruments and quiet vocals where every nuance needs to be captured clearly. This extreme gain capability combined with the tape saturation and filters allows for exceptional flexibility in sound shaping.

High-quality CineMag USA transformers for optimum signal transmission

The WA-MPX is equipped with specially wound CineMag transformers, which are manufactured in the USA and are known for their high fidelity and stability. These transformers contribute significantly to the characteristic warmth and clarity of the WA-MPX and ensure a detailed and dynamic signal transmission. The 600Ω transformers in the microphone input and the transformers for line level guarantee a perfect balance between warmth and precision in the sound.

Versatile sound options and analog sound control

The WA-MPX offers several sound processing options to shape the sound exactly to the musician's individual wishes. The integrated 80 Hz high-pass filter is ideal for controlling low-frequency noise, while the 2 kHz low-pass filter focuses the mids and provides additional warmth for assertive vocals and instruments. These filter options add punch and precision to the sound, which is particularly useful for drums and bass.

The classic Warm Audio tone control modifies the impedance of the input transformer and adds even more analog timbre to the signal. This function allows the harmonic overtones to be amplified, making the sound even more lively and full. Together with the tape saturation control, the WA-MPX offers everything you need to give a mix that characteristic vintage touch.

Versatile connection options and robust construction

The WA-MPX is equipped with multiple inputs, including an XLR mic input, a TS instrument input and a TRS line input, allowing easy connection to microphones, instruments and other audio devices. Outputs include XLR and TRS line level, allowing the WA-MPX to integrate seamlessly into any studio setup. A VU meter provides precise level metering while giving the unit a classic, retro-inspired look.

With a robust aluminum front panel, a sturdy steel housing and vintage Bakelite-style knobs, the WA-MPX combines the aesthetics of the 50s and 60s with modern design. The integrated 48V phantom power supply and the internal IEC 115V/230V power input make the device versatile and user-friendly.

Conclusion: Warm Audio WA-MPX - The perfect tube preamp for classic analog sound

The Warm Audio WA -MPX is an excellent choice for anyone looking for the unmistakable analog sound of a tube preamplifier. With its authentic tape saturation, high-quality workmanship and versatile sound options, the WA-MPX delivers the warm, harmonically saturated sound that is essential for professional recordings and mixes. The WA-MPX is ideal for the studio, but also for use on stage, and thanks to its handcrafted circuit design and sturdy construction, it is a durable and reliable device for demanding audio professionals.
