Warm Audio EQP-WA – Tube Program Equalizer
OVERVIEW
The One EQ to Rule Them All
The EQP-WA is a faithful recreation of the most renowned tube equalizer in recording history, the original vintage Pultec-Style “EQP-1A.” Just like the original, the all-analog EQP-WA is able to maintain full, harmonically rich tone while adding and subtracting frequency information, compared to plug-ins and digital emulations that are unable to preserve the full character while sculpting the tone. The 100% analog, fully-discrete circuit adds anything from thump to punch to brilliance on the way in or in post-processing to program material. The original has been used on legendary recordings by artists like Led Zeppelin, John Mayer, Bob Dylan, The Beatles and more. Producers from George Martin to Rick Rubin have used vintage originals to shape the sound of music’s biggest hits for decades.
Pure Sound-Shaping with Rich Analog Tone
Equalization is a key element of any professional recording, and the EQP-1A-style of EQ is the industry benchmark for professional EQ without compromising tone. To combat the expected tone loss during signal processing, the EQP-WA is designed just like the original, with discrete tubes and transformers designed to enhance tone, not destroy it. Loaded with premium 12AX7 & 12AU7 tubes and CineMag transformers, the output amplifier section of the EQP-WA passes the EQ-corrected audio through tubes and transformers to maintain signal integrity and rich tone. This results in more width, depth, and separation on tracks. Favourite uses for the EQP-WA include setting vocals in a mix, adding final touches to drums and final mixes, separating guitar tracks, and dialling in clarity to bass guitar. Even with that exhaustive list, there’s no studio application that the EQP-WA can’t handle.
Applications
Vocals – Sculpted for the Mix:
Find the exact frequencies that will help the vocals either sit “on top” of the mix, or “set back” for that extra professional polish.
Acoustic Guitar – Dial in Percussive Tones:
Dial in pick and string noise on the acoustic guitar, adding texture to mixes with dense track counts.
Bass – Craft Rich & Clear Tones:
Perfectly balance the “boom” of the bass with the clear fretboard clarity on both electric and stand-up acoustic bass.
Drum Bus – Tune to the Track:
Boost and cut sub bass to lower-mids and handle mids-highs to tune your drums to complement the mix.
“Warm Audio has taken a world-class design, added some useful features and improved some of the original units’ antiquated internal components to create a superb product that punches way above its weight.” – MusicTech

KEY HIGHLIGHTS
USA-Made Transformer From Cinemag
The USA-made CineMag transformers inside the EQP-WA are made like they used to be, with rich history from some of the most sought-after analog consoles. The transformers inside the EQP-WA let through all of the rich gain and harmonic overtones from the tubes that can be lost in the process of altering frequencies in an analog signal. This additional layer of analog colour allows the EQP-WA to deliver pure analog warmth associated with the most prized vintage tube-based program equalizers.
Premium Name-Brand Vacuum Tubes
One of the key elements of the EQP-WA sonic signature is the analog warmth of the output gain. Using premium vacuum tubes, the EQP-WA adds rich character after the equalization stage to deliver a recording with ideal EQ without sacrificing rich analog tone.
Hand-Tested, Elite Build Quality*
Every single EQP-WA is meticulously hand tested & inspected at Warm HQ in Austin, TX by real musicians and engineers with passion for superior sound.

The low-frequency selector determines the frequency that can be emphasized with the amount control. Boosting & cutting at the same time can create desirable phase effects and clean up the midrange after the boost. Boost low frequencies from 0dB @ ‘0’ setting to 12dB @ ‘10’ setting. Cut low frequencies from 0dB @ ‘0’ setting to 18dB @ ‘10’ setting.
