Fusion-derived EQ in a 500 Series Module

Derived from the Violet EQ section of SSL's much-admired Fusion processor, the UltraViolet gives you two bands of minimum-phase shelving equalization. This 500 Series module takes things a bit further than Fusion, however, with two additional fully parametric mid bands and a Focus control for surgical tone sculpting. You also get a 5-frequency selectable highpass filter, along with a ±12dB output trim and a bypass switch. Simply stated, the Solid State Logic UltraViolet is a stellar-sounding EQ with eminently musical curves. And here's a quick tip for an instant radio-ready sound: pair the UltraViolet with the 500 Series SSL Bus Compressor module, and every mix will sound like a finished record.

Four bands of flexible SSL-style sound shaping

The UltraViolet puts four flexible bands of legendary SSL tone sculpting right at your fingertips. For starters, you get minimum-phase high shelving and low shelving bands, which were culled from SSL's acclaimed Fusion processor. You also get two fully parametric midbands. The high band gives you a frequency selection of 8kHz, 12kHz, 16kHz, and 20kHz; the low band offers choices of 30Hz, 50Hz, 70Hz, and 90Hz. The high midband ranges from 400Hz to 6kHz, while the low midband ranges from 100Hz to 1.1kHz. You also get a switchable highpass filter with Off, 30Hz, 40Hz, and 50Hz settings. Here at Sweetwater, our favorite feature on the UV is Focus mode, which is available on each individual midband. Pressing the Focus button narrows the corresponding band's Q setting and increases its gain range beyond the normal ±9dB for laser-precise, surgical sonic sculpting.

Solid State Logic UltraViolet EQ Features:

  • Packs 4 bands of SSL console-style sound shaping into a 500 Series module
  • Fusion-derived high/low shelving bands and 2 fully parametric midbands with ±9dB of gain
  • High band gives you a frequency selection of 8kHz, 12kHz, 16kHz, and 20kHz
  • Low band gives you a frequency selection of 30Hz, 50Hz, 70Hz, and 90Hz
  • High midband ranges from 400Hz–6kHz with a continuously variable Q
  • Low midband ranges from 100Hz–1.1kHz with a continuously variable Q
  • Highpass filter includes Off, 30Hz, 40Hz, and 50Hz settings
  • Focus narrows the corresponding band's Q setting and increases its gain range for surgical sonic sculpting
  • ±12dB output trim makes achieving proper gain staging a breeze
  • Bypass switch makes A/B comparisons a piece of cake

Reviews

Does exactly what I hoped it would
I bought the GBus 500 series and then saw this and watched some videos. I like the idea of having an eq to impart some magic at the end of my stereo bus and it does just that. Together with the GBuss it's night and day when they are bypassed.

Truly a steal, wow
Building my 10 slot chassis has been one of the more expensive projects in the studio, so when I saw a STEREO SSL EQ going for around six hundred bucks, I couldn't believe it. After using it extensively on a variety of material I can confidently say this module provides that definitive SSL sound.

In my experience, this module excels at both making precise cuts and pleasant wide boosts. Other reviews lead me to believe that this unit doesn't have a lot of "mojo" when boosting, but I found that to be false. Boosting a drum bus at 400hz with a wide Q sounds absolutely delicious, getting a nice and tight vocal group is ridiculously simple.

The LF and HF bands are exact copies of what is present on my Fusion processor, extremely powerful and easy to use. However, the two MF bands add a whole new layer of control when doing mix bus work. The boosts and cuts sound very full and natural and can easily add a lot of depth to an otherwise sterile mix

Overall, this EQ is very transparent with what it does. You will have a hard time making the unit sound bad for any application. The controls are exactly what you would expect from SSL, and the Focus mode is a very welcomed addition compared to some of the original E series EQ's. The only real downside to this unit is not being able to use it in mono, but that is far from a deal breaker. If you need THE SSL EQ for mix work, treat yourself and get the UV.

Better Than Expected
Pros:
- Unbelievable Price For What You Get
- Stereo EQ That Can Be Used On Tracks, Mix Bus, Or An Insert
- Multiple Frequency Bands To Tweak The Sound
- Focus Mode Is Nice To Help Find A Specific Frequency
- Trim Knob Is Nice To reduce or drive harder into a compressor after this

Cons:
- Only Low Cut & High Shelf Are Stepped, however recall is not bad given dotted markers
- Sounds Best When Cutting Frequencies, Unlike A Very High End EQ that sounds good boosting or cutting like a pultec or Maag EQ

Conclusion: I was very skeptical going into this, but decided to buy because of the price and I wanted a stereo eq for my mix bus to address specific mid frequencies and gently cutting out a bit of mud. I already have a SSL bus +, Gainlabs Empress, & Maag Mastering EQ. I figured I could use this on the SSL Bus + side chain insert if it didn't sound good, but I was pleasantly surprised. The person who said this is best for touching things up before all your other gear is correct. It doesn't have transformers or tubes, so it's not going to provide a lot of mojo, just super clean. It does not affect the stereo image. Helps clean up a mix slightly before it goes into the other analog gear. There are people online who rant about SSL products being made in China, but way I look at it is they are more affordable this way and I've never been disappointed in SSL. I appreciate them making things affordable for the average audio enthusiast or professional. My feeling is if anyone doesn't like this EQ it is because they wanted it to do extreme things like boosting a lot or adding mojo or they don't have great converters or monitors to hear it as all analog gear is highly dependent on that. Can't beat this for the price.
