Critic Reviews

Solid State Logic Fusion

soundonsound.com

The SSL Fusion Processor brings a luxurious touch to your mixes, with its clever design and multiple processing tools like Vintage Drive and HF Compressor, enhancing audio with a pleasing analogue warmth. Its build quality and user-friendly interface stand out, making it a joy to use in various setups. However, some users might find the stereo image controls a bit too aggressive, as well as the lack of precise adjustment options. Overall, while it might not be the most flexible option on the market, it excels in delivering a smooth, character-rich sound that will appeal to those seeking to elevate their mix bus or mastering chain without breaking the bank.

Solid State Logic Fusion - A Real World Review - Mixonline

The SSL Fusion Processor delivers a robust array of tonal enhancements that can elevate any mix, making it a must-have for both seasoned pros and hobbyists. Its Vintage Drive section impresses with warm saturation, while the Violet EQ subtly enhances clarity without harshness. The Stereo Image feature is particularly noteworthy, creating remarkable space in a mix. However, its price point may deter some, especially those accustomed to digital alternatives. Overall, the Fusion might just sidestep the hardware versus plugin debate with its versatility and musicality, but it may not be for everyone.

tapeop.com

SSL's Fusion Master Processor offers a unique blend of analog processing capabilities, delivering impressive tonal manipulation and a wide frequency response. Its five individual sections, including vintage drive and high-frequency compression, provide versatility for mixing and mastering. However, mastering the unit's gain structure and interactions can be challenging, requiring time and experimentation. While it excels in enhancing acoustic tracks, some users may find the transformer section's effect on synth-heavy music less desirable. Overall, Fusion stands out in functionality but may not suit every workflow, leading to a mixed reception among engineers.

Kéž bys tak nešuměl!

Dal bych tak rád plných 5 hvězd, protože SSL Fusion je opravdu skvělý "multiefekt". Má jeden - a možná jenom jeden - problém a tím je šum u jedné fukce s názvem Vintage drive. Ten šum je skutečně silný, opravdu výrazný a zatím jsem nenašel cestu, jak ho jakkoliv efektivně potlačit nebo v lepším případě zcela zničit hardwareovou cestou. O pokus hledat frekvenci šumu se nebavme, to je zcela zbytečné a vaši skladbu tím pouze zničíte. Bohužel - Vintage drive je to nejlepší pro mě z celého SSL Fusion. Takže ano, pokud chcete analogovou simulaci pásu, pak počítejte s tím, že to prostě bude šumět :) Tento nástroj mám v mém nahrávacím studiu Sunteem records.

Rather than put it straight on his mix buss, Marroquin started off using the Fusion on stereo keyboard tracks, then guitars.

“Because I am still on the big SSL - so not in the box – I've been using Fusion as an insert,” he says. “I have got to tell you, I just loved what I heard. It's like having a chain of three or four different plugins all in one. And if like so many people, you are working in the box, you can just put it across part of your stereo buss chain, which is great, because it's got an EQ, it's got a Vintage Drive, a spreader – it's just a very versatile box, and one of my favourite toys right now!”

Fusion can really improve the stereo image of a sound, Marroquin reveals: “I have been using it on a lot of synths – especially if they're playing a melodic line, because Fusion allows me to control how wide I want it to be: I can EQ it very quickly, I can add filters to it; I can make it so that it fits perfectly in the mix, and it's still punchy. I am sure I can use it on a lot of other things, too – on backing vocals for R&B records, I know this will sound delicious.

“It'll also work as a great sweetener, so you can make your mixes super-wide using this box; and SSL have done such a great job too, as it's so simple. Some mixers will do a whole song, and at the very end, they'll just slap on that final EQ or compressor, or a tiny little bit of air at the end of the mix; not to master, but to give it that extra 5%. And this is perfect for that. If you're in the box, put Fusion on bypass, have it in your chain, then towards the end of your mix, just pop it in, and wait for the whole mix to pop out, man!”

“I have got to tell you, I just loved what I heard. It's like having a chain of three or four different plugins all in one.
