Warm Audio EQP-WA Tube Eq Review
3, 4, 5, 8, 10, 12 and 16kHz, exactly mimicking the classic units, with +18dB of available boost. As this is a peaking EQ, a bandwidth control is employed to adjust the contour of the EQ curve from sharp to broad. The HF shelving Cut control has five selectable frequencies at 3, 4, 5, 10 and 20kHz; the first two frequency points are additional to the original design.
Practical Tip
For a great bass drum sound perform the legendary low-end trick of boosting and cutting simultaneously. Select 30Hz and dial-in equal amounts of boost and cut until you hear the low-end gain weight while the boxy mids are reduced.
The high-frequency section at 3, 4 or 5kHz will bring out the click of the beater and a touch of extreme top cut produces a beautifully rounded bass drum sound.
Inside the Box
Internally, the fully-discrete unit features a vacuum tube make up gain amplifier, which employs two high-voltage Tung-Sol valves (tubes): a 12AX7 and 12AU7. Warm has sensibly avoided using a valve rectifier as the Pultecs did; purists may bemoan this, but the truth is that solid-state rectifiers are much more efficient than tubes, and arguably allow the unit to perform better. Input and output transformers, along with the inductor, are by the ever popular CineMag brand.
On the rear of the unit is a connector for an IEC power lead (supplied), along with balanced Input and Output connectors that support both XLR and quarter-inch TRS jack cables. Warm recommends that it’s not advisable to connect both input connectors or both output connectors at once.
Straight out of the box we were impressed with the feel of the unit, which oozes quality. The large vintage-styled pots are smooth in operation and finely indented for precise recall of settings, which is particularly useful when using a pair, as we did, for stereo processing. The chicken-head type rotary switches that allow selection of frequencies engage with a satisfying clunk that feels purposeful and inspires confidence.
Even the powered-up LED glows a gentle red that doesn’t dazzle like many units that opt for neon-blue indicators. Only the Warm logo is a blot on the unit’s faceplate. On the company’s earlier orange units (WA12 and Tonebeast) the logo looked funky in black. On this new grey blue, not so much.
We made many of our tried and tested EQ moves with the unit – a touch of 10kHz sparkle on snare drum, some 16kHz air on vocal tracks, and a subtle 60Hz boost on bass guitar to name but three – as well as making use of the extra frequency bands not featured on traditional units. The 800Hz setting in the low-end section was excellent at giving some body to an electric guitar track and we further tailored the sound to add some bite and presence at 3kHz. As a final touch we cut some extreme top at 20kHz where very little useful electric guitar information exists, creating a big, full-bodied sound that was still able to cut through the mix.
As we usually work in stereo, we couldn’t resist strapping our two EQP-WA review units across some stereo mix-busses and previously prepared final stereo mixes; the results were very good. This is something we’ve been unable to do with our single Pultec copy, unless we processed each channel separately, but now we can see why this type of equalizer is so revered as a program equalizer.
With many Pultec clones costing several times the asking price of Warm’s new version, owning more than one is beyond the reach of many smaller studios. Now it’s possible to have a pair for less money than any of the single-channel boutique units. With that in mind, the question we found ourselves asking wasn’t, “can we afford to buy both of these?”, rather “can we afford not to?”
Don’t make the mistake of thinking that the low price of the EQP-WA equates with low quality. This new Warm product can hold its own in comparison with any Pultec-styled EQ. The ability to perform all the tricks of these units coupled with the advantage of additional frequency points surely makes this a first among equalizers
